|
|
|
This plugin gathers statistics for all InfiniBand devices and ports on the
|
|
|
|
|
system. These are the counters that can be found in
|
|
|
|
|
`/sys/class/infiniband/<dev>/port/<port>/counters/`

|
|
|
|
```toml

|
|
|
Actual metrics depend on the InfiniBand devices, the plugin uses a simple
|
|
|
|
|
mapping from counter -> counter value.
