# Configuration
|
||||
|
||||
Configuration is implemented using a single json document that is distributed over network and may be persisted as file.
|
||||
Granularity can be either `node`, or `core`. Frequency can be set on a per measurement basis.
|
||||
Supported metrics are documented [here](https://github.com/ClusterCockpit/cc-specifications/blob/master/metrics/lineprotocol.md).
|
||||
|
||||
``` json
|
||||
{
|
||||
"sink": "db.monitoring.center.de",
|
||||
"report": {
|
||||
levels: ["core","node"],
|
||||
interval: 120

}
|

```
|
||||
|
||||
All available collectors are listed in the above JSON. There are currently two sinks supported `influxdb` and `stdout`. 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. For most systems, the `likwid` collector has to do two measurements, thus `interval` must be larger than two times `duration`.

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 the **node** metric `mem_used`
|
||||
* `loadavgMetric.go`: Reads `/proc/loadavg` and submits the **node** metrics:
|
||||
* `load_one`
|
||||
* `load_five`
|
||||
* `load_fifteen`
|
||||
* `netstatMetric.go`: Reads `/proc/net/dev` and submits for all network devices (except loopback `lo`) the **node** metrics:
|
||||
* `<dev>_bytes_in`
|
||||
* `<dev>_bytes_out`
|
||||
* `<dev>_pkts_in`
|
||||
* `<dev>_pkts_out`
|
||||
* `lustreMetric.go`: Reads Lustre's stats file `/proc/fs/lustre/llite/lnec-XXXXXX/stats` and submits the **node** metrics:
|
||||
* `read_bytes`
|
||||
* `read_requests`
|
||||
* `write_bytes`
|
||||
* `write_bytes`
|
||||
* `open`
|
||||
* `close`
|
||||
* `getattr`
|
||||
* `setattr`
|
||||
* `statfs`
|
||||
* `inode_permission`
|
||||
* `infinibandMetric.go`: Reads InfiniBand LID from `/sys/class/infiniband/mlx4_0/ports/1/lid` and uses the `perfquery` command to read the **node** metrics:
|
||||
* `ib_recv`
|
||||
* `ib_xmit`
|
||||
* `likwidMetric.go`: Reads hardware performance events using LIKWID. It submits **socket** and **cpu** metrics:
|
||||
* `mem_bw` (socket)
|
||||
* `power` (socket, Sum of RAPL domains PKG and DRAM)
|
||||
* `flops_dp` (cpu)
|
||||
* `flops_sp` (cpu)
|
||||
* `flops_any` (cpu, `2*flops_dp + flops_sp`)
|
||||
* `cpi` (cpu)
|
||||
* `clock` (cpu)
|
||||
|
||||
# Installation
|
||||
Only the `likwidMetric.go` requires preparation steps. For this, the `Makefile` can be used. The LIKWID build needs to be configured:
|
||||
* Version of LIKWID in `LIKWID_VERSION`
|
||||
* Target user for LIKWID's accessdaemon in `DAEMON_USER`. The user has to have enough permissions to read the `msr` and `pci` device files
|
||||
* Target group for LIKWID's accessdaemon in `DAEMON_GROUP`
|
||||
|
||||
It performs the following steps:
|
||||
* Download LIKWID tarball
|
||||
* Unpacking
|
||||
* Adjusting configuration for LIKWID build
|
||||
* Build it
|
||||
* Copy all required files into `collectors/likwid`
|
||||
* The accessdaemon is installed with the suid bit set using `sudo` also into `collectors/likwid`

This folder contains the sinks for the cc-metric-collector.
|
||||
|
||||
# `sink.go`
|
||||
The base class/configuration is located in `sink.go`.
|
||||
|
||||
# Sinks
|
||||
There are currently two sinks shipped with the cc-metric-collector:
|
||||
* `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, user, password and database name are in the global configuration file
|
||||
|
||||
# Installation
|
||||
Nothing to do, all sinks are pure Go code
