# Overview
|
||||||
|
|
||||||
|
ClusterCockpit uses the InfluxData line-protocol for collecting the node metric
|
||||||
|
data.
|
||||||
|
|
||||||
|
```
|
||||||
|
<measurement>,<tag set> <field set> <timestamp [s]>
|
||||||
|
```
|
||||||
|
|
||||||
|
Supported measurements:
|
||||||
|
* node – Tags: host, cpu
|
||||||
|
* socket – Tags: host, socket
|
||||||
|
* cpu -- Tags: host, cpu
|
||||||
|
|
||||||
|
## Supported node level fields
|
||||||
|
|
||||||
|
* `load`
|
||||||
|
* `mem_used`
|
||||||
|
* `net_bw` - split into `ib_bw` and `eth_bw` if required
|
||||||
|
* `file_bw` - split into multiple file systems if required
|
||||||
|
|
||||||
|
## Supported socket fields
|
||||||
|
|
||||||
|
All socket metrics can be aggregated to coarser granularity.
|
||||||
|
|
||||||
|
* `power`
|
||||||
|
* `mem_bw`
|
||||||
|
|
||||||
|
## Supported cpu level fields
|
||||||
|
|
||||||
|
All cpu metrics can be aggregated to coarser granularity.
|
||||||
|
|
||||||
|
* `ipc`
|
||||||
|
* `flops_any`
|
||||||
|
* `clock`
