Configuration is implemented using a single json document that is distributed over network and may be persisted as file.
Supported metrics are documented [here](https://github.com/ClusterCockpit/cc-specifications/blob/master/metrics/lineprotocol_alternative.md).
There is a main configuration file with basic settings that point to the other configuration files for the different components.

}
```
The `interval` defines how often the metrics should be read and send to the sink. The `duration` tells collectors how long one measurement has to take. An example for this is the `likwid` collector which starts the hardware performance counter, waits for `duration` seconds and stops the counters again. If you configure a collector to do two measurments, the `duration` must be at least half the `interval`.
The `interval` defines how often the metrics should be read and send to the sink. The `duration` tells collectors how long one measurement has to take. This is important for some collectors, like the `likwid` collector.
The `collectors` contains all collectors executed collectors. Each collector can be configured in the `collect_config` section. A more detailed list of all collectors and their configuration options can be found in the [README for collectors](./collectors/README.md).
See the component READMEs for their configuration:
* [`collectors`](./collectors/README.md)
* [`sinks`](./sinks/README.md)
* [`receivers`](./receivers/README.md)
* [`router`](./internal/metricRouter/README.md)
The `sink` section contains the configuration where the data should be transmitted to. There are currently four sinks supported `influxdb`, `nats`, `http` and `stdout`. See [README for sinks](./sinks/README.md) for more information about the individual sinks and which configuration field they are using.
In the `default_tags` section, one can define key-value-pairs (only strings) that are added to each sent out metric. This can be useful for cluster names like in the example JSON or information like rank or island for orientation.
With `receiver`, the collector can be used as a router by receiving metrics and forwarding them to the configured sink. There are currently only types `none` (for no receiver) and `nats`. For more information see the [README in receivers](./receivers/README.md).

# CCMetric collectors
This folder contains the collectors for the cc-metric-collector.
# `metricCollector.go`
The base class/configuration is located in `metricCollector.go`.
# Collectors
* `memstatMetric.go`: Reads `/proc/meminfo` to calculate **node** metrics. It also combines values to the metric `mem_used`
* `loadavgMetric.go`: Reads `/proc/loadavg` and submits **node** metrics:
* `netstatMetric.go`: Reads `/proc/net/dev` and submits for all network devices as the **node** metrics.
* `lustreMetric.go`: Reads Lustre's stats files and submits **node** metrics:
* `infinibandMetric.go`: Reads InfiniBand metrics. It uses the `perfquery` command to read the **node** metrics but can fallback to sysfs counters in case `perfquery` does not work.
* `likwidMetric.go`: Reads hardware performance events using LIKWID. It submits **socket** and **cpu** metrics
* `cpustatMetric.go`: Read CPU specific values from `/proc/stat`
* `topprocsMetric.go`: Reads the TopX processes by their CPU usage. X is configurable
* `nvidiaMetric.go`: Read data about Nvidia GPUs using the NVML library
* `tempMetric.go`: Read temperature data from `/sys/class/hwmon/hwmon*`
* `ipmiMetric.go`: Collect data from `ipmitool` or as fallback `ipmi-sensors`
* `customCmdMetric.go`: Run commands or read files and submit the output (output has to be in InfluxDB line protocol!)
If any of the collectors cannot be initialized, it is excluded from all further reads. Like if the Lustre stat file is not a valid path, no Lustre specific metrics will be recorded.

}
}
}
```
The configuration of the collectors in the main config files consists of two parts: active collectors (`collectors`) and collector configuration (`collect_config`). At startup, all collectors in the `collectors` list is initialized and, if successfully initialized, added to the active collectors for metric retrieval. At initialization the collector-specific configuration from the `collect_config` section is handed over. Each collector has own configuration options, check at the collector-specific section.
In contrast to the configuration files for sinks and receivers, the collectors configuration is not a list but a set of dicts. This is required because we didn't manage to partially read the type before loading the remaining configuration. We are eager to change this to the same format.
## `memstat`
# Available collectors
```json
"memstat": {
"exclude_metrics": [
"mem_used"
]
}
```
The `memstat` collector reads data from `/proc/meminfo` and outputs a handful **node** metrics. If a metric is not required, it can be excluded from forwarding it to the sink.
Metrics:
* `mem_total`
* `mem_sreclaimable`
* `mem_slab`
* `mem_free`
* `mem_buffers`
* `mem_cached`
* `mem_available`
* `mem_shared`
* `swap_total`
* `swap_free`
* `mem_used` = `mem_total` - (`mem_free` + `mem_buffers` + `mem_cached`)
## `loadavg`
```json
"loadavg": {
"exclude_metrics": [
"proc_run"
]
}
```
The `loadavg` collector reads data from `/proc/loadavg` and outputs a handful **node** metrics. If a metric is not required, it can be excluded from forwarding it to the sink.
Metrics:
* `load_one`
* `load_five`
* `load_fifteen`
* `proc_run`
* `proc_total`
## `netstat`
```json
"netstat": {
"exclude_devices": [
"lo"
]
}
```
The `netstat` collector reads data from `/proc/net/dev` and outputs a handful **node** metrics. If a device is not required, it can be excluded from forwarding it to the sink. Commonly the `lo` device should be excluded.
Metrics:
* `bytes_in`
* `bytes_out`
* `pkts_in`
* `pkts_out`
The device name is added as tag `device`.
## `diskstat`
```json
"diskstat": {
"exclude_metrics": [
"read_ms"
],
}
```
The `netstat` collector reads data from `/proc/net/dev` and outputs a handful **node** metrics. If a metric is not required, it can be excluded from forwarding it to the sink.
Metrics:
* `reads`
* `reads_merged`
* `read_sectors`
* `read_ms`
* `writes`
* `writes_merged`
* `writes_sectors`
* `writes_ms`

_Example config suitable for AMD Zen3_
The `likwid` collector reads hardware performance counters at a **hwthread** and **socket** level. The configuration looks quite complicated but it is basically copy&paste from [LIKWID's performance groups](https://github.com/RRZE-HPC/likwid/tree/master/groups). The collector made multiple iterations and tried to use the performance groups but it lacked flexibility. The current way of configuration provides most flexibility.
The logic is as following: There are multiple eventsets, each consisting of a list of counters+events and a list of metrics. If you compare a common performance group with the example setting above, there is not much difference:
```
EVENTSET -> "events": {
FIXC1 ACTUAL_CPU_CLOCK -> "FIXC1": "ACTUAL_CPU_CLOCK",
FIXC2 MAX_CPU_CLOCK -> "FIXC2": "MAX_CPU_CLOCK",
PMC0 RETIRED_INSTRUCTIONS -> "PMC0" : "RETIRED_INSTRUCTIONS",
PMC1 CPU_CLOCKS_UNHALTED -> "PMC1" : "CPU_CLOCKS_UNHALTED",
PMC2 RETIRED_SSE_AVX_FLOPS_ALL -> "PMC2": "RETIRED_SSE_AVX_FLOPS_ALL",
PMC3 MERGE -> "PMC3": "MERGE",
-> }
```
The metrics are following the same procedure:
```
METRICS -> "metrics": [
IPC PMC0/PMC1 -> {
-> "name" : "IPC",
-> "calc" : "PMC0/PMC1",
-> "socket_scope": false,
-> "publish": true
-> }
-> ]
```
The `socket_scope` option tells whether it is submitted per socket or per hwthread. If a metric is only used for internal calculations, you can set `publish = false`.
Since some metrics can only be gathered in multiple measurements (like the memory bandwidth on AMD Zen3 chips), configure multiple eventsets like in the example config and use the `globalmetrics` section to combine them. **Be aware** that the combination might be misleading because the "behavior" of a metric changes over time and the multiple measurements might count different computing phases.

# Contributing own collectors
A collector reads data from any source, parses it to metrics and submits these metrics to the `metric-collector`. A collector provides three function:
* `Init(config []byte) error`: Initializes the collector using the given collector-specific config in JSON.
* `Read(duration time.Duration, out *[]lp.MutableMetric) error`: Read, parse and submit data to the `out` list. If the collector has to measure anything for some duration, use the provided function argument `duration`.
* `Name() string`: Return the name of the collector
* `Init(config json.RawMessage) error`: Initializes the collector using the given collector-specific config in JSON. Check if needed files/commands exists, ...
* `Initialized() bool`: Check if a collector is successfully initialized
* `Read(duration time.Duration, output chan ccMetric.CCMetric)`: Read, parse and submit data to the `output` channel as [`CCMetric`](../internal/ccMetric/README.md). If the collector has to measure anything for some duration, use the provided function argument `duration`.
* `Close()`: Closes down the collector.
It is recommanded to call `setup()` in the `Init()` function.
Finally, the collector needs to be registered in the `metric-collector.go`. There is a list of collectors called `Collectors` which is a map (string -> pointer to collector). Add a new entry with a descriptive name and the new collector.
Finally, the collector needs to be registered in the `collectorManager.go`. There is a list of collectors called `AvailableCollectors` which is a map (`collector_type_string` -> `pointer to MetricCollector interface`). Add a new entry with a descriptive name and the new collector.

## `ibstat` collector
```json
"ibstat": {
"perfquery_path" : "<path to perfquery command>",
"exclude_devices": [
"mlx4"
]
}
```
The `ibstat` collector reads either data through the `perfquery` command or the sysfs files below `/sys/class/infiniband/<device>`.
Metrics:
* `ib_recv`
* `ib_xmit`
The collector adds a `device` tag to all metrics

## `ipmistat` collector
```json
"ipmistat": {
"ipmitool_path": "/path/to/ipmitool",
"ipmisensors_path": "/path/to/ipmi-sensors",
}
```
The `ipmistat` collector reads data from `ipmitool` (`ipmitool sensor`) or `ipmi-sensors` (`ipmi-sensors --sdr-cache-recreate --comma-separated-output`).
The metrics depend on the output of the underlying tools but contain temperature, power and energy metrics.

_Example config suitable for AMD Zen3_
The `likwid` collector reads hardware performance counters at a **hwthread** and **socket** level. The configuration looks quite complicated but it is basically copy&paste from [LIKWID's performance groups](https://github.com/RRZE-HPC/likwid/tree/master/groups). The collector made multiple iterations and tried to use the performance groups but it lacked flexibility. The current way of configuration provides most flexibility.
The logic is as following: There are multiple eventsets, each consisting of a list of counters+events and a list of metrics. If you compare a common performance group with the example setting above, there is not much difference:
```
EVENTSET -> "events": {
FIXC1 ACTUAL_CPU_CLOCK -> "FIXC1": "ACTUAL_CPU_CLOCK",
FIXC2 MAX_CPU_CLOCK -> "FIXC2": "MAX_CPU_CLOCK",
PMC0 RETIRED_INSTRUCTIONS -> "PMC0" : "RETIRED_INSTRUCTIONS",
PMC1 CPU_CLOCKS_UNHALTED -> "PMC1" : "CPU_CLOCKS_UNHALTED",
PMC2 RETIRED_SSE_AVX_FLOPS_ALL -> "PMC2": "RETIRED_SSE_AVX_FLOPS_ALL",
PMC3 MERGE -> "PMC3": "MERGE",
-> }
```
The metrics are following the same procedure:
```
METRICS -> "metrics": [
IPC PMC0/PMC1 -> {
-> "name" : "IPC",
-> "calc" : "PMC0/PMC1",
-> "socket_scope": false,
-> "publish": true
-> }
-> ]
```
The `socket_scope` option tells whether it is submitted per socket or per hwthread. If a metric is only used for internal calculations, you can set `publish = false`.
Since some metrics can only be gathered in multiple measurements (like the memory bandwidth on AMD Zen3 chips), configure multiple eventsets like in the example config and use the `globalmetrics` section to combine them. **Be aware** that the combination might be misleading because the "behavior" of a metric changes over time and the multiple measurements might count different computing phases.

## `memstat` collector
```json
"memstat": {
"exclude_metrics": [

```
The `memstat` collector reads data from `/proc/meminfo` and outputs a handful **node** metrics. If a metric is not required, it can be excluded from forwarding it to the sink.
Metrics:
* `mem_total`
* `mem_sreclaimable`
* `mem_slab`
* `mem_free`
* `mem_buffers`
* `mem_cached`
* `mem_available`
* `mem_shared`
* `swap_total`
* `swap_free`
* `mem_used` = `mem_total` - (`mem_free` + `mem_buffers` + `mem_cached`)

## `nvidia` collector
```json
"nvidia": {
"exclude_devices" : [
"0","1"
],
"exclude_metrics": [
"nv_fb_memory",
"nv_fan"
]
}
```
Metrics:
* `nv_util`
* `nv_mem_util`
* `nv_mem_total`
* `nv_fb_memory`
* `nv_temp`
* `nv_fan`
* `nv_ecc_mode`
* `nv_perf_state`
* `nv_power_usage_report`
* `nv_graphics_clock_report`
* `nv_sm_clock_report`
* `nv_mem_clock_report`
* `nv_max_graphics_clock`
* `nv_max_sm_clock`
* `nv_max_mem_clock`
* `nv_ecc_db_error`
* `nv_ecc_sb_error`
* `nv_power_man_limit`
* `nv_encoder_util`
* `nv_decoder_util`
It uses a separate `type` in the metrics. The output metric looks like this:
`<name>,type=accelerator,type-id=<nvidia-gpu-id> value=<metric value> <timestamp>`

## `topprocs` collector
```json
"topprocs": {
"num_procs": 5
}
```
The `topprocs` collector reads the TopX processes (sorted by CPU utilization, `ps -Ao comm --sort=-pcpu`).
In contrast to most other collectors, the metric value is a `string`.

# ClusterCockpit metrics
As described in the [ClusterCockpit specifications](https://github.com/ClusterCockpit/cc-specifications), the whole ClusterCockpit stack uses metrics in the InfluxDB line protocol format. This is also the input and output format for the ClusterCockpit Metric Collector but internally it uses an extended format while processing, named CCMetric.
It is basically a copy of the [InfluxDB line protocol](https://github.com/influxdata/line-protocol) `MutableMetric` interface with one extension. Besides the tags and fields, it contains a list of meta information (re-using the `Tag` structure of the original protocol):
```golang
type ccMetric struct {
name string // same as
tags []*influx.Tag // original
fields []*influx.Field // Influx
tm time.Time // line-protocol
meta []*influx.Tag
}
type CCMetric interface {
influx.MutableMetric // the same functions as defined by influx.MutableMetric
RemoveTag(key string) // this is not published by the original influx.MutableMetric
Meta() map[string]string
MetaList() []*inlux.Tag
AddMeta(key, value string)
HasMeta(key string) bool
GetMeta(key string) (string, bool)
RemoveMeta(key string)
}
```
The `CCMetric` interface provides the same functions as the `MutableMetric` like `{Add, Remove, Has}{Tag, Field}` and additionally provides `{Add, Remove, Has}Meta`.
The InfluxDB protocol creates a new metric with `influx.New(name, tags, fields, time)` while CCMetric uses `ccMetric.New(name, tags, meta, fields, time)` where `tags` and `meta` are both of type `map[string]string`.
You can copy a CCMetric with `FromMetric(other CCMetric) CCMetric`. If you get an `influx.Metric` from a function, like the line protocol parser, you can use `FromInfluxMetric(other influx.Metric) CCMetric` to get a CCMetric out of it (see `NatsReceiver` for an example).

# CC Metric Router
The CCMetric router sits in between the collectors and the sinks and can be used to add and remove tags to/from traversing [CCMetrics](../ccMetric/README.md).
# Configuration
```json
{
"add_tags" : [
{
"key" : "cluster",
"value" : "testcluster",
"if" : "*"
},
{
"key" : "test",
"value" : "testing",
"if" : "name == 'temp_package_id_0'"
}
],
"delete_tags" : [
{
"key" : "unit",
"value" : "*",
"if" : "*"
}
],
"interval_timestamp" : true
}
```
There are three main options `add_tags`, `delete_tags` and `interval_timestamp`. `add_tags` and `delete_tags` are lists consisting of dicts with `key`, `value` and `if`. The `value` can be omitted in the `delete_tags` part as it only uses the `key` for removal. The `interval_timestamp` setting means that a unique timestamp is applied to all metrics traversing the router during an interval.
# Conditional manipulation of tags
The `if` setting allows conditional testing of a single metric like in the example:
```json
{
"key" : "test",
"value" : "testing",
"if" : "name == 'temp_package_id_0'"
}
```
If the CCMetric name is equal to 'temp_package_id_0', it adds an additional tag `test=testing` to the metric.
In order to match all metrics, you can use `*`, so in order to add a flag per default, like the `cluster=testcluster` tag in the example.

# MultiChanTicker
The idea of this ticker is to multiply the output channels. The original Golang `time.Ticker` provides only a single output channel, so the signal can only be received by a single other class. This ticker allows to add multiple channels which get all notified about the time tick.
```golang
type MultiChanTicker interface {
Init(duration time.Duration)
AddChannel(chan time.Time)
}
```
The MultiChanTicker is created similarly to the common `time.Ticker`:
```golang
NewTicker(duration time.Duration) MultiChanTicker
```
Afterwards, you can add channels:
```golang
t := MultiChanTicker(duration)
c1 := make(chan time.Time)
c2 := make(chan time.Time)
t.AddChannel(c1)
t.AddChannel(c2)
for {
select {
case t1 := <- c1:
log.Print(t1)
case t2 := <- c2:
log.Print(t2)
}
}
```
The result should be the same `time.Time` output in both channels, notified "simultaneously".

This folder contains the receivers for the cc-metric-collector.
# CCMetric receivers
# `metricReceiver.go`
The base class/configuration is located in `metricReceiver.go`.
This folder contains the ReceiveManager and receiver implementations for the cc-metric-collector.
# Receivers
* `natsReceiver.go`: Receives metrics from the Nats transport system in Influx line protocol encoding. The database name is used as subscription subject for the NATS messages. It uses https://github.com/nats-io/nats.go
# Configuration
# Installation
Nothing to do, all receivers are pure Go code
# Receiver configuration
The configuration file for the receivers is a list of configurations. The `type` field in each specifies which receiver to initialize.
```json
"receiver": {
[
{
"type": "nats",
"address": "nats://my-url"
"address": "nats://my-url",
"port" : "4222",
"database": "testcluster"
},
}
]
```
## `nats`
The receiver connects to `address` and `port` and subscribes itself for all messages with topic `database`. The default port is `4222`.
## Type `nats`
```json
{
"type": "nats",
"address": "<nats-URI or hostname>",
"port" : "<portnumber>",
"database": "<subscribe topic>"
}
```
The `nats` receiver subscribes to the topic `database` and listens on `address` and `port` for metrics in the InfluxDB line protocol.
# Contributing own receivers
A receiver contains three functions and is derived from the type `Receiver` (in `metricReceiver.go`):
* `Init(config ReceiverConfig) error`
* `Start() error`
* `Close()`
* `Name() string`
* `SetSink(sink chan ccMetric.CCMetric)`
The data structures should be set up in `Init()` like opening a file or server connection. The `Start()` function should either start a go routine or issue some other asynchronous mechanism for receiving metrics. The `Close()` function should tear down anything created in `Init()`.
Finally, the receiver needs to be registered in the `metric-collector.go`. There is a list of receivers called `Receivers` which is a map (string -> pointer to receiver). Add a new entry with a descriptive name and the new receiver.
Finally, the receiver needs to be registered in the `receiveManager.go`. There is a list of receivers called `AvailableReceivers` which is a map (`receiver_type_string` -> `pointer to Receiver interface`). Add a new entry with a descriptive name and the new receiver.

This folder contains the sinks for the cc-metric-collector.
# CCMetric sinks
# `metricSink.go`
The base class/configuration is located in `metricSink.go`.
This folder contains the SinkManager and sink implementations for the cc-metric-collector.
# Sinks
* `stdoutSink.go`: Writes all metrics to `stdout` in InfluxDB line protocol. The sink does not use https://github.com/influxdata/line-protocol to reduce the executed code for debugging
* `influxSink.go`: Writes all metrics to an InfluxDB database instance using a blocking writer. It uses https://github.com/influxdata/influxdb-client-go . Configuration for the server, port, ssl, password, database name and organisation are in the global configuration file. The 'password' is used for the token and the 'database' for the bucket. It uses the v2 API of Influx.
* `natsSink.go`: Sends all metrics to an NATS server using the InfluxDB line protocol as encoding. It uses https://github.com/nats-io/nats.go . Configuration for the server, port, user, password and database name are in the global configuration file. The database name is used as subject for the NATS messages.
* `httpSink.go`: Sends all metrics to an HTTP endpoint `http://<host>:<port>/<database>` using a POST request. The body of the request will consist of lines in the InfluxDB line protocol. In case password is specified, that password is used as a JWT in the 'Authorization' header.
# Configuration
# Installation
Nothing to do, all sinks are pure Go code
# Sink configuration
The configuration file for the sinks is a list of configurations. The `type` field in each specifies which sink to initialize.
```json
"sink": {
"user": "testuser",
"password": "testpass",
"host": "127.0.0.1",
"port": "9090",
"database": "testdb",
"organization": "testorg",
"ssl": false
"type": "stdout"
[
{
"type" : "stdout",
"meta_as_tags" : false
},
{
"type" : "http",
"host" : "localhost",
"port" : "4123",
"database" : "ccmetric",
"password" : "<jwt token>"
}
]
```
## `stdout`
When configuring `type = stdout`, all metrics are printed to stdout. No further configuration is required or touched, so you can leave your other-sink-config in there and just change the `type` for debugging purposes
This example initializes two sinks, the `stdout` sink printing all metrics to the STDOUT and the `http` sink with the given `host`, `port`, `database` and `password`.
## `influxdb`
The InfluxDB sink uses blocking write operations to write to an InfluxDB database using the v2 API. It uses the following configuration options:
* `host`: Hostname of the database instance
* `port`: Portnumber (as string) of the database
* `database`: Name of the database, called 'bucket' in InfluxDB v2
* `organization`: The InfluxDB v2 API uses organizations to separate database instances running on the same host
* `ssl`: Boolean to activate SSL/TLS
* `user`: Although the v2 API uses API keys instead of username and password, this field can be used if the sink should authentificate with `username:password`. If you want to use an API key, leave this field empty.
* `password`: API key for the InfluxDB v2 API or password if `user` is set
If `meta_as_tags` is set, all meta information attached to CCMetric are printed out as tags.
## `nats`
* `host`: Hostname of the NATS server
* `port`: Portnumber (as string) of the NATS server
* `user`: Username for authentification in the NATS transport system
* `password`: Password for authentification in the NATS transport system
## Type `stdout`
```json
{
"type" : "stdout",
"meta_as_tags" : <true|false>
}
```
The `stdout` sink dumps all metrics to the STDOUT.
## Type `http`
```json
{
"type" : "http",
"host" : "<hostname>",
"port" : "<portnumber>",
"database" : "<database name>",
"password" : "<jwt token>",
"meta_as_tags" : <true|false>
}
```
The sink uses POST requests to send metrics to `http://<host>:<port>/<database>` using the JWT token as a JWT in the 'Authorization' header.
## Type `nats`
```json
{
"type" : "nats",
"host" : "<hostname>",
"port" : "<portnumber>",
"user" : "<username>",
"password" : "<password>",
"database" : "<database name>"
"meta_as_tags" : <true|false>
}
```
This sink publishes the CCMetric in a NATS environment using `host`, `port`, `user` and `password` for connecting. The metrics are published using the topic `database`.
## Type `influxdb`
```json
{
"type" : "influxdb",
"host" : "<hostname>",
"port" : "<portnumber>",
"user" : "<username>",
"password" : "<password or API key>",
"database" : "<database name>"
"organization": "<InfluxDB v2 organization>",
"ssl" : <true|false>,
"meta_as_tags" : <true|false>

This sink submits the CCMetrics to an InfluxDB time-series database. It uses `host`, `port` and `ssl` for connecting. For authentification, it uses either `user:password` if `user` is set and only `password` as API key. The `organization` and `database` are used for writing to the correct database.
## `http`
* `host`: Hostname of the HTTP server
* `port`: Portnumber (as string) of the HTTP server
* `database`: Endpoint to write to. HTTP POST requests are performed on `http://<host>:<port>/<database>`
* `password`: JSON Web token used for authentification
# Contributing own sinks
A sink contains three functions and is derived from the type `Sink` (in `metricSink.go`):
A sink contains three functions and is derived from the type `Sink`:
* `Init(config SinkConfig) error`
* `Write(measurement string, tags map[string]string, fields map[string]interface{}, t time.Time) error`
* `Write(point CCMetric) error`
* `Flush() error`
* `Close()`
The data structures should be set up in `Init()` like opening a file or server connection. The `Write()` function takes a measurement, tags, fields and a timestamp and writes/sends the data. For non-blocking sinks, the `Flush()` method tells the sink to drain its internal buffers. The `Close()` function should tear down anything created in `Init()`.

Finally, the sink needs to be registered in the `metric-collector.go`. There is a list of sinks called `Sinks` which is a map (sink_type_string -> pointer to sink). Add a new entry with a descriptive name and the new sink.
Finally, the sink needs to be registered in the `sinkManager.go`. There is a list of sinks called `AvailableSinks` which is a map (`sink_type_string` -> `pointer to sink interface`). Add a new entry with a descriptive name and the new sink.
