A node agent for measuring, processing and forwarding node level metrics. It is part of the ClusterCockpit ecosystem.
A node agent for measuring, processing and forwarding node level metrics. It is part of the [ClusterCockpit ecosystem](./docs/introduction.md).
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).

## `schedstat` collector
```json
"schedstat": {
}
```
The `schedstat` collector reads data from /proc/schedstat and calculates a load value, separated by hwthread. This might be useful to detect bad cpu pinning on shared nodes etc.
Metric:
* `cpu_load_core`

# Building the cc-metric-collector
In most cases, a simple `make` in the main folder is enough to get a `cc-metric-collector` binary. It is basically a `go build` but some collectors require additional tasks. There is currently no Golang interface to LIKWID, so it uses `cgo` to create bindings but `cgo` requires the LIKWID header files. Therefore, it checks whether LIKWID is installed and if not it downloads LIKWID and copies the headers.
## System integration
The main configuration settings for system integration are pre-defined in `scripts/cc-metric-collector.config`. The file contains the UNIX user and group used for execution, the PID file location and other settings. Adjust it accordingly and copy it to `/etc/default/cc-metric-collector`
```bash
$ install --mode 644 \
--owner $CC_USER \
--group $CC_GROUP \
scripts/cc-metric-collector.config /etc/default/cc-metric-collector
$ edit /etc/default/cc-metric-collector
```
### SysVinit and similar
If you are using a init system based in `/etc/init.d` daemons, you can use the sample `scripts/cc-metric-collector.init`. It reads the basic configuration from `/etc/default/cc-metric-collector`
```bash
$ install --mode 755 \
--owner $CC_USER \
--group $CC_GROUP \
scripts/cc-metric-collector.init /etc/init.d/cc-metric-collector
```
### Systemd
If you are using `systemd` as init system, you can use the sample systemd service file `scripts/cc-metric-collector.service`, the configuration file `scripts/cc-metric-collector.config`.
```bash
$ install --mode 644 \
--owner $CC_USER \
--group $CC_GROUP \
scripts/cc-metric-collector.service /etc/systemd/system/cc-metric-collector.service
$ systemctl enable cc-metric-collector
```
## RPM
In order to get a RPM packages for cc-metric-collector, just use:
```bash
$ make RPM
```
It uses the RPM SPEC file `scripts/cc-metric-collector.spec` and requires the RPM tools (`rpm` and `rpmspec`) and `git`.
## DEB
In order to get very simple Debian packages for cc-metric-collector, just use:
```bash
$ make DEB
```
It uses the DEB control file `scripts/cc-metric-collector.control` and requires `dpkg-deb`, `awk`, `sed` and `git`. It creates only a binary deb package.
_This option is not well tested and therefore experimental_

The `CCMetric` interface provides the same functions as the `MutableMetric` like `{Add, Remove, Has}{Tag, Field}` and additionally provides `{Add, Remove, Has}Meta`.
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.

## 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.
### Configuration structure
```json
{
"<redfish receiver name>": {
"type": "redfish",
"username": "<user A>",
"password": "<password A>",
"endpoint": "https://%h-bmc",
"exclude_metrics": [ "min_consumed_watts" ],
"client_config": [
{
"host_list": [ "<host 1>", "<host 2>" ]
},
{
"host_list": [ "<host 3>", "<host 4>" ]
"disable_power_metrics": true
},
{
"host_list": [ "<host 5>" ],
"username": "<user B>",
"password": "<password B>",
"endpoint": "https://%h-BMC",
"disable_thermal_metrics": true
}
]
}
}
```
Global settings:
- `fanout`: Maximum number of simultaneous redfish connections (default: 64)
- `interval`: How often the redfish power metrics should be read and send to the sink (default: 30 s)
- `http_insecure`: Control whether a client verifies the server's certificate (default: true == do not verify server's certificate)
- `http_timeout`: Time limit for requests made by this HTTP client (default: 10 s)
Global and per redfish device settings (per redfish device settings overwrite the global settings):
- `disable_power_metrics`: disable collection of power metrics
- `disable_processor_metrics`: disable collection of processor metrics
- `disable_thermal_metrics`: disable collection of thermal metrics
- `exclude_metrics`: list of excluded metrics
- `username`: User name to authenticate with
- `password`: Password to use for authentication
- `endpoint`: URL of the redfish service (placeholder `%h` gets replaced by the hostname)
Per redfish device settings:
- `host_list`: List of hosts with the same client configuration
