## `lenovo_dense_power` collector
|
|
|
|
```json
|
|
"megware_eureka": {
|
|
"u20_path": "/path/to/ipmitool",
|
|
"use_sudo": true
|
|
}
|
|
```
|
|
|
|
The `megware_eureka` collector reads power and other metrics from Megware Eureka machines via `u20`.
|
|
If the u20 tool is available for your machines, it's possible that this collector is compatible.
|
|
If you don't have access to u20, please contact your Megware sales person.
|
|
|
|
You can test the collector compatibility by running the following command:
|
|
|
|
```
|
|
$ u20 values --read GET_MPS_POLL_VALUES
|
|
```
|
|
|
|
If this returns a JSON with energy, voltage and current readings, you're fine.
|
|
|
|
In addition, `u20` typically requires root to run.
|
|
In order to run `cc-metric-collector` without root priviliges, you can enable `use_sudo`.
|
|
Add a file like this in `/etc/sudoers.d/` to allow `cc-metric-collector` to run the required commands:
|
|
|
|
```
|
|
# Do not log the following sudo commands from monitoring, since this causes a lot of log spam.
|
|
# However keep log_denied enabled, to detect failures
|
|
Defaults: monitoring !log_allowed, !pam_session
|
|
|
|
# Allow to use u20 for Megware power readings
|
|
monitoring ALL = (root) NOPASSWD:/usr/bin/u20 values --read GET_MPS_POLL_VALUES
|
|
```
