## `BeeGFS on Demand` collector
|
||||
This Collector is to collect BeeGFS on Demand (BeeOND) metadata clientstats.
|
||||
|
||||
```json
|
||||
"beegfs_meta": {
|
||||
"beegfs_path": "/usr/bin/beegfs-ctl",
|
||||
"exclude_filesystem": [
|
||||
"/mnt/ignore_me"
|
||||
],
|
||||
"exclude_metrics": [
|
||||
"ack",
|
||||
"entInf",
|
||||
"fndOwn"
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
The `BeeGFS On Demand (BeeOND)` collector uses the `beegfs-ctl` command to read performance metrics for
|
||||
BeeGFS filesystems.
|
||||
|
||||
The reported filesystems can be filtered with the `exclude_filesystem` option
|
||||
in the configuration.
|
||||
|
||||
The path to the `beegfs-ctl` command can be configured with the `beegfs_path` option
|
||||
in the configuration.
|
||||
|
||||
When using the `exclude_metrics` option, the excluded metrics are summed as `other`.
|
||||
|
||||
Important: The metrics listed below, are similar to the naming of BeeGFS. The Collector prefixes these with `beegfs_cstorage`(beegfs client storage).
|
||||
|
||||
For example beegfs metric `open`-> `beegfs_cstorage_open`
|
||||
|
||||
Available Metrics:
|
||||
|
||||
* sum
|
||||
* ack
|
||||
* close
|
||||
* entInf
|
||||
* fndOwn
|
||||
* mkdir
|
||||
* create
|
||||
* rddir
|
||||
* refrEnt
|
||||
* mdsInf
|
||||
* rmdir
|
||||
* rmLnk
|
||||
* mvDirIns
|
||||
* mvFiIns
|
||||
* open
|
||||
* ren
|
||||
* sChDrct
|
||||
* sAttr
|
||||
* sDirPat
|
||||
* stat
|
||||
* statfs
|
||||
* trunc
|
||||
* symlnk
|
||||
* unlnk
|
||||
* lookLI
|
||||
* statLI
|
||||
* revalLI
|
||||
* openLI
|
||||
* createLI
|
||||
* hardlnk
|
||||
* flckAp
|
||||
* flckEn
|
||||
* flckRg
|
||||
* dirparent
|
||||
* listXA
|
||||
* getXA
|
||||
* rmXA
|
||||
* setXA
|
||||
* mirror
|
||||
|
||||
The collector adds a `filesystem` tag to all metrics

## `BeeGFS on Demand` collector
|
||||
This Collector is to collect BeeGFS on Demand (BeeOND) storage stats.
|
||||
|
||||
```json
|
||||
"beegfs_storage": {
|
||||
"beegfs_path": "/usr/bin/beegfs-ctl",
|
||||
"exclude_filesystem": [
|
||||
"/mnt/ignore_me"
|
||||
],
|
||||
"exclude_metrics": [
|
||||
"ack",
|
||||
"storInf",
|
||||
"unlnk"
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
The `BeeGFS On Demand (BeeOND)` collector uses the `beegfs-ctl` command to read performance metrics for BeeGFS filesystems.
|
||||
|
||||
The reported filesystems can be filtered with the `exclude_filesystem` option
|
||||
in the configuration.
|
||||
|
||||
The path to the `beegfs-ctl` command can be configured with the `beegfs_path` option
|
||||
in the configuration.
|
||||
|
||||
When using the `exclude_metrics` option, the excluded metrics are summed as `other`.
|
||||
|
||||
Important: The metrics listed below, are similar to the naming of BeeGFS. The Collector prefixes these with `beegfs_cstorage_`(beegfs client meta).
|
||||
For example beegfs metric `open`-> `beegfs_cstorage_`
|
||||
|
||||
Note: BeeGFS FS offers many Metadata Information. Probably it makes sense to exlcude most of them. Nevertheless, these excluded metrics will be summed as `beegfs_cstorage_other`.
|
||||
|
||||
Available Metrics:
|
||||
|
||||
* "sum"
|
||||
* "ack"
|
||||
* "sChDrct"
|
||||
* "getFSize"
|
||||
* "sAttr"
|
||||
* "statfs"
|
||||
* "trunc"
|
||||
* "close"
|
||||
* "fsync"
|
||||
* "ops-rd"
|
||||
* "MiB-rd/s"
|
||||
* "ops-wr"
|
||||
* "MiB-wr/s"
|
||||
* "endbg"
|
||||
* "hrtbeat"
|
||||
* "remNode"
|
||||
* "storInf"
|
||||
* "unlnk"
|
||||
|
||||
|
||||
The collector adds a `filesystem` tag to all metrics

|
||||
- The global metrics are metrics which require data from all event set measurements to be derived. The inputs are the metrics in the event sets. Similar to the metrics in the event sets, the global metrics are defined by a name, a formula, a scope and a publish flag. See event set metrics for details. The only difference is that there is no access to the raw event measurements anymore but only to the metrics. So, the idea is to derive a metric in the "eventsets" section and reuse it in the "globalmetrics" part. If you need a metric only for deriving the global metrics, disable forwarding of the event set metrics. **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.

||||
|
||||
Additional options:
|
||||
- `access_mode` : Method to use for hardware performance monitoring (`direct` access as root user, `accessdaemon` for the daemon mode)
|
||||
- `accessdaemon_path`: Folder with the access daemon `likwid-accessD`, commonly `$LIKWID_INSTALL_LOC/sbin`
|
||||
- `force_overwrite`: Same as setting `LIKWID_FORCE=1`. In case counters are already in-use, LIKWID overwrites their configuration to do its measurements
|
||||
- `invalid_to_zero`: In some cases, the calculations result in `NaN` or `Inf`. With this option, all `NaN` and `Inf` values are replaces with `0.0`.

You can copy this JSON and add it to the `eventsets` list. If you specify multiple event sets, you can add globally derived metrics in the extra `global_metrics` section with the metric names as variables.

|
||||
### Mixed usage between daemon and users
|
||||
|
||||
LIKWID checks the file `/var/run/likwid.lock` before performing any interfering operations. Who is allowed to access the counters is determined by the owner of the file. If it does not exist, it is created for the current user. So, if you want to temporarly allow counter access to a user (e.g. in a job):
|
||||

||||
Before (SLURM prolog, ...)
|

```

# Configuring the CC metric collector
|
||||
|
||||
The configuration of the CC metric collector consists of five configuration files: one global file and four component related files.
|
||||
|
||||
## Global configuration
|
||||
|
||||
The global file contains the paths to the other four files and some global options.
|
||||
|
||||
```json
|
||||
{
|
||||
"sinks": "sinks.json",
|
||||
"collectors" : "collectors.json",
|
||||
"receivers" : "receivers.json",
|
||||
"router" : "router.json",
|
||||
"interval": 10,
|
||||
"duration": 1
|
||||
}
|
||||
```
|
||||
|
||||
Be aware that the paths are relative to the execution folder of the cc-metric-collector binary, so it is recommended to use absolute paths.
|
||||
|
||||
## Component configuration
|
||||
|
||||
The others are mainly list of of subcomponents: the collectors, the receivers, the router and the sinks. Their role is best shown in a picture:
|
||||

||||

|
||||

|
||||
|
||||
|
||||
```
|
||||
|
||||
There are four parts:
|
||||
- The collectors read data from files, execute commands and call dynamically loaded library function and send it to the router
|
||||
- The router can process metrics by cacheing and evaluating functions and conditions on them
|
||||
- The sinks send the metrics to storage backends
|
||||
- The receivers can be used to receive metrics from other collectors and forward them to the router. They can be used to create a tree-like structure of collectors.
|
||||
|
||||
(A maybe better differentiation between collectors and receivers is that the collectors are called periodically while the receivers have their own logic and submit metrics at any time)
|
||||
|
||||
|
||||
### Collectors configuration file
|
||||
|
||||
The collectors configuration file tells which metrics should be queried from the system. The metric gathering is logically grouped in so called 'Collectors'. So there are Collectors to read CPU, memory or filesystem statistics. The collectors configuration file is a list of these collectors with collector-specific configurations:
|
||||
|
||||
```json
|
||||
{
|
||||
"cpustat" : {},
|
||||
"diskstat": {
|
||||
"exclude_metrics": [
|
||||
"disk_total"
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The first one is the CPU statistics collector without any collector-specific setting. The second one enables disk mount statistics but excludes the metric `disk_total`.
|
||||
|
||||
All names and possible collector-specific configuration options can be found [here](../collectors/README.md).
|
||||
|
||||
Some collectors might dynamically load shared libraries. In order to enable these collectors, make sure that the shared library path is part of the `LD_LIBRARY_PATH` environment variable.
|
||||
|
||||
### Sinks configuration file
|
||||
|
||||
The sinks define the output/sending of metrics. The metrics can be forwarded to multiple sinks, even to sinks of the same type. The sinks configuration file is a list of these sinks, each with an individual name.
|
||||
|
||||
```json
|
||||
{
|
||||
"myinflux" : {
|
||||
"type" : "influxasync",
|
||||
"host": "localhost",
|
||||
"port": "8086",
|
||||
"organization" : "testorga",
|
||||
"database" : "testbucket",
|
||||
"password" : "<my secret JWT>"
|
||||
},
|
||||
"companyinflux" : {
|
||||
"type" : "influxasync",
|
||||
"host": "companyhost",
|
||||
"port": "8086",
|
||||
"organization" : "company",
|
||||
"database" : "main",
|
||||
"password" : "<company's secret JWT>"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The above example configuration file defines two sink, both ot type `influxasync`. They are differentiated internally by the names: `myinflux` and `companyinflux`.
|
||||
|
||||
All types and possible sink-specific configuration options can be found [here](../sinks/README.md).
|
||||
|
||||
Some sinks might dynamically load shared libraries. In order to enable these sinks, make sure that the shared library path is part of the `LD_LIBRARY_PATH` environment variable.
|
||||
|
||||
### Router configuration file
|
||||
|
||||
The collectors and the sinks are connected through the router. The router forwards the metrics to the sinks but enables some data processing. A common example is to tag all passing metrics like adding `cluster=mycluster`. But also aggregations like "take the average of all 'ipc' metrics" (ipc -> Instructions Per Cycle). Since the configurations of these aggregations can be quite complicated, we refer to the router's [README](../internal/metricRouter/README.md).
|
||||
|
||||
A simple router configuration file to start with looks like this:
|
||||
|
||||
```json
|
||||
{
|
||||
"add_tags" : [
|
||||
{
|
||||
"key" : "cluster",
|
||||
"value" : "mycluster",
|
||||
"if" : "*"
|
||||
}
|
||||
],
|
||||
"interval_timestamp" : false,
|
||||
"num_cache_intervals" : 0
|
||||
}
|
||||
```
|
||||
|
||||
With the `add_tags` section, we tell to attach the `cluster=mycluster` tag to each (`*` metric). The `interval_timestamp` tell the router to not touch the timestamp of metrics. It is possible to send all metrics within an interval with a common time stamp to avoid later alignment issues. The `num_cache_intervals` diables the cache completely. The cache is only required if you want to do complex metric aggregations.
|
||||
|
||||
All configuration options can be found [here](../internal/metricRouter/README.md).
|
||||
|
||||
### Receivers configuration file
|
||||
|
||||
The receivers are a special feature of the CC Metric Collector to enable simpler integration into exising setups. While collectors query data from the local system, the receivers commonly get data from other systems through some network technology like HTTP or NATS. The idea is keep the current setup but send it to a CC Metric Collector which forwards it to the the destination system (if a sink exists for it). For most setups, the receivers are not required and an the receiver config file should contain only an empty JSON map (`{}`).
|
||||
|
||||
```json
|
||||
{
|
||||
"nats_rack0": {
|
||||
"type": "nats",
|
||||
"address" : "nats-server.example.org",
|
||||
"port" : "4222",
|
||||
"subject" : "rack0",
|
||||
},
|
||||
"nats_rack1": {
|
||||
"type": "nats",
|
||||
"address" : "nats-server.example.org",
|
||||
"port" : "4222",
|
||||
"subject" : "rack1",
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
This example configuration creates two receivers with the names `nats_rack0` and `nats_rack1`. While one subscribes to metrics published with the `rack0` subject, the other one subscribes to the `rack0` subject. The NATS server is the same as it manages all subjects in a subnet. (As example, the router could add tags `rack=0` and `rack=1` respectively to the received metrics.)
|
||||
|
||||
All types and possible receiver-specific configuration options can be found [here](../receivers/README.md).

|

|

"subject": "<subscribe topic>"
|
||||
}
|
||||
```
|
||||
## Available receivers
|
||||
|
||||
The `nats` receiver subscribes to the topic `database` and listens on `address` and `port` for metrics in the InfluxDB line protocol.
|
||||
- [`nats`](./natsReceiver.md): Receive metrics from the NATS network
|
||||
- [`prometheus`](./prometheusReceiver.md): Scrape data from a Prometheus client
|
||||
- [`http`](./httpReceiver.md): Listen for HTTP Post requests transporting metrics in InfluxDB line protocol
|
||||
|
||||
# Contributing own receivers
|
||||
A receiver contains a few functions and is derived from the type `Receiver` (in `metricReceiver.go`):
|
||||
* `Start() error`
|
||||
* `Close()`
|
||||
* `Name() string`
|
||||
* `SetSink(sink chan lp.CCMetric)`
|
||||
* `New<Typename>(name string, config json.RawMessage)`
|
||||
|
||||
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 `receiveManager.go`. There is a list of receivers called `AvailableReceivers` which is a map (`receiver_type_string` -> `pointer to NewReceiver function`). Add a new entry with a descriptive name and the new receiver.
|
||||
For an example, check the [sample receiver](./sampleReceiver.go)
