+A node agent for measuring, processing and forwarding node level metrics. It is part of the [ClusterCockpit ecosystem](https://clustercockpit.org/docs/overview/).

 The metric collector sends (and receives) metric in the [InfluxDB line protocol](https://docs.influxdata.com/influxdb/cloud/reference/syntax/line-protocol/) as it provides flexibility while providing a separation between tags (like index columns in relational databases) and fields (like data columns).

 One might think this does not happen often but often used metrics in the world of performance engineering like Instructions-per-Cycle (IPC) or more frequently the actual CPU clock are derived with events like `CPU_CLK_UNHALTED_CORE` (Intel) which do not increment in halted state (as the name implies). In there are different power management systems in a chip which can cause a hardware thread to go in such a state. Moreover, if no cycles are executed by the core, also many other events are not incremented as well (like `INSTR_RETIRED_ANY` for retired instructions and part of IPC).

+### `lockfile_path` option
+LIKWID can be configured with a lock file with which the access to the performance monitoring registers can be disabled (only the owner of the lock file is allowed to access the registers). When the `lockfile_path` option is set, the collector subscribes to changes to this file to stop monitoring if the owner of the lock file changes. This feature is useful when users should be able to perform own hardware performance counter measurements through LIKWID or any other tool.
+
 ### `send_*_total values` option

 - `send_core_total_values`: Metrics, which are usually collected on a per hardware thread basis, are additionally summed up per CPU core.

With the `include_devices` list you can specify which network devices should be measured. **Note**: Most other collectors use an _exclude_ list instead of an include list. Optionally, you can define an interface_aliases mapping. For each canonical device (as listed in include_devices), you may provide an array of aliases that may be reported by the system. When an alias is detected, it is preferred for matching, while the output tag stype-id always shows the actual system-reported name.

 This collector reads running average power limit (RAPL) monitoring attributes to compute average power consumption metrics. See <https://www.kernel.org/doc/html/latest/power/powercap/powercap.html#monitoring-attributes>.

 The Likwid metric collector provides similar functionality.

 # The MetricAggregator

 In some cases, further combination of metrics or raw values is required. For that strings like `foo + 1` with runtime dependent `foo` need to be evaluated. The MetricAggregator relies on the [`gval`](https://github.com/PaesslerAG/gval) Golang package to perform all expression evaluation. The `gval` package provides the basic arithmetic operations but the MetricAggregator defines additional ones.
@@ -35,4 +46,4 @@ The MetricAggregator provides these functions additional to the `Full` language
 ## Limitations

 - Since the metrics are written in JSON files which do not allow `""` without proper escaping inside of JSON strings, you have to use `''` for strings.
- Since `\` is interpreted by JSON as escape character, it cannot be used in metrics. But it is required to write regular expressions. So instead of `/`, use `%` and the MetricAggregator replaces them after reading the JSON file.

 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.

+**Note**: Use the [message processor configuration](https://github.com/ClusterCockpit/cc-lib/blob/main/messageProcessor/README.md) (option `process_messages`) instead of `add_tags`, `delete_tags`, `drop_metrics`, `drop_metrics_if`, `rename_metrics`, `normalize_units` and `change_unit_prefix`. These options are deprecated and will be removed in future versions. Until then, they are added to the message processor.

 In some cases, you need to derive new metrics based on the metrics arriving during an interval. This can be done in the `interval_aggregates` section. The logic is similar to the other metric manipulation and filtering options. A cache stores all metrics that arrive during an interval. At the beginning of the *next* interval, the list of metrics is submitted to the MetricAggregator. It derives new metrics and submits them back to the MetricRouter, so they are sent in the next interval but have the timestamp of the previous interval beginning.

-# 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                 // Measurement name
-    meta   map[string]string      // map of meta data tags
-    tags   map[string]string      // map of of tags
-    fields map[string]interface{} // map of of fields
-    tm     time.Time              // timestamp
-}
-
-type CCMetric interface {
-    ToPoint(metaAsTags map[string]bool) *write.Point  // Generate influxDB point for data type ccMetric
-    ToLineProtocol(metaAsTags map[string]bool) string // Generate influxDB line protocol for data type ccMetric
-    String() string                                   // Return line-protocol like string
-
-    Name() string        // Get metric name
-    SetName(name string) // Set metric name
-
-    Time() time.Time     // Get timestamp
-    SetTime(t time.Time) // Set timestamp
-

-    AddTag(key, value string)                  // Add a tag
-    GetTag(key string) (value string, ok bool) // Get a tag by its key
-    HasTag(key string) (ok bool)               // Check if a tag key is present
-    RemoveTag(key string)                      // Remove a tag by its key
-

-    AddMeta(key, value string)                  // Add a meta data tag
-    GetMeta(key string) (value string, ok bool) // Get a meta data tab addressed by its key
-    HasMeta(key string) (ok bool)               // Check if a meta data key is present
-    RemoveMeta(key string)                      // Remove a meta data tag by its key

-    GetField(key string) (value interface{}, ok bool) // Get a field addressed by its key
-    HasField(key string) (ok bool)                    // Check if a field key is present
-    RemoveField(key string)                           // Remove a field addressed by its key
-}
-
-func New(name string, tags map[string]string, meta map[string]string, fields map[string]interface{}, tm time.Time) (CCMetric, error)
-func FromMetric(other CCMetric) CCMetric
-func FromInfluxMetric(other lp.Metric) CCMetric
-```
-
-The `CCMetric` interface provides the same functions as the `MutableMetric` like `{Add, Get, Remove, Has}{Tag, Field}` and additionally provides `{Add, Get, 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).
-
-Although the [cc-specifications](https://github.com/ClusterCockpit/cc-specifications/blob/master/interfaces/lineprotocol/README.md) defines that there is only a `value` field for the metric value, the CCMetric still can have multiple values similar to the InfluxDB line protocol.

 # 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.

-## Configuration
-
-The configuration file for the receivers is a list of configurations. The `type` field in each specifies which receiver to initialize.
-
-```json
-{
-  "myreceivername" : {
-    "type": "receiver-type",
-    <receiver-specific configuration>
-  }
-}
-```
-
-This allows to specify
-
-## Available receivers
-
- [`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
- [`ipmi`](./ipmiReceiver.md): Read IPMI sensor readings
- [`redfish`](redfishReceiver.md) Use the Redfish (specification) to query thermal and power metrics
-
-## Contributing own receivers
-
-A receiver contains a few functions and is derived from the type `Receiver` (in `metricReceiver.go`):
-
-For an example, check the [sample receiver](./sampleReceiver.go)

-## `http` receiver
-
-The `http` receiver can be used receive metrics through HTTP POST requests.

-### Configuration structure
-
-```json
-{
-  "<name>": {
-    "type": "http",
-    "address" : "",
-    "port" : "8080",
-    "path" : "/write",
-    "idle_timeout": "120s",
-    "username": "myUser",
-    "password": "myPW"
-  }
-}
-```
-
- `type`: makes the receiver a `http` receiver
- `address`: Listen address
- `port`: Listen port
- `path`: URL path for the write endpoint
- `idle_timeout`: Maximum amount of time to wait for the next request when keep-alives are enabled should be larger than the measurement interval to keep the connection open
- `keep_alives_enabled`: Controls whether HTTP keep-alives are enabled. By default, keep-alives are enabled.
- `username`: username for basic authentication
- `password`: password for basic authentication
-
-The HTTP endpoint listens to `http://<address>:<port>/<path>`
-
-### Debugging
-
- Install [curl](https://curl.se/)
- Use curl to send message to `http` receiver
-
-  ```bash
-  curl http://localhost:8080/write \
-  --user "myUser:myPW" \
-  --data \
-  "myMetric,hostname=myHost,type=hwthread,type-id=0,unit=Hz value=400000i 1694777161164284635

-## IPMI Receiver
-
-The IPMI Receiver uses `ipmi-sensors` from the [FreeIPMI](https://www.gnu.org/software/freeipmi/) project to read IPMI sensor readings and sensor data repository (SDR) information. The available metrics depend on the sensors provided by the hardware vendor but typically contain temperature, fan speed, voltage and power metrics.

-
-Global settings:
-
- `interval`: How often the IPMI sensor metrics should be read and send to the sink (default: 30 s)
-
-Global and per IPMI device settings (per IPMI device settings overwrite the global settings):
-
- `exclude_metrics`: list of excluded metrics e.g. fan_speed, power, temperature, utilization, voltage
- `fanout`: Maximum number of simultaneous IPMI connections (default: 64)
- `driver_type`: Out of band IPMI driver (default: LAN_2_0)
- `username`: User name to authenticate with
- `password`: Password to use for authentication
- `endpoint`: URL of the IPMI device (placeholder `%h` gets replaced by the hostname)
-
-Per IPMI device settings:
-
- `host_list`: List of hosts with the same client configuration
- `cli_options`: Additional command line options for ipmi-sensors

-## `nats` receiver
-
-The `nats` receiver can be used receive metrics from the NATS network. The `nats` receiver subscribes to the topic `database` and listens on `address` and `port` for metrics in the InfluxDB line protocol.
-
-### Configuration structure
-
-```json
-{
-  "<name>": {
-    "type": "nats",
-    "address" : "nats-server.example.org",
-    "port" : "4222",
-    "subject" : "subject"
-  }
-}
-```
-
- `type`: makes the receiver a `nats` receiver
- `address`: Address of the NATS control server
- `port`: Port of the NATS control server
- `subject`: Subscribes to this subject and receive metrics
-
-### Debugging
-
- Install NATS server and command line client
- Start NATS server
-
-  ```bash
-  nats-server --net nats-server.example.org --port 4222
-  ```
-
- Check NATS server works as expected
-
-  ```bash
-  nats --server=nats-server-db.example.org:4222 server check
-  ```
-
- Use NATS command line client to subscribe to all messages
-
-  ```bash
-  nats --server=nats-server-db.example.org:4222 sub ">"
-  ```
-
- Use NATS command line client to send message to NATS receiver
-
-  ```bash
-  nats --server=nats-server-db.example.org:4222 pub subject \
-  "myMetric,hostname=myHost,type=hwthread,type-id=0,unit=Hz value=400000i 1694777161164284635

-## Redfish receiver
-
-The Redfish receiver uses the [Redfish (specification)](https://www.dmtf.org/standards/redfish) to query thermal and power metrics. Thermal metrics may include various fan speeds and temperatures. Power metrics may include the current power consumption of various hardware components. It may also include the minimum, maximum and average power consumption of these components in a given time interval. The receiver will poll each configured redfish device once in a given interval. Multiple devices can be accessed in parallel to increase throughput.
