## `lenovo_dense_power` collector
|
||||
|
||||
```json
|
||||
"lenovo_dense_power": {
|
||||
"ipmitool_path": "/path/to/ipmitool",
|
||||
"use_sudo": true,
|
||||
"include_metrics" : []
|
||||
}
|
||||
```
|
||||
|
||||
The `lenovo_dense_power` collector reads power from Lenovo Dense machines via `ipmitool` (`ipmitool raw ...`). This collector is known to only work on the following machines. Others are not supported, so use at your *OWN* risk:
|
||||
|
||||
System | Compatibility | Power measured
|
||||
--- | --- | ---
|
||||
Lenovo ThinkSystem SD650 V2/V3 | untested, but should work | node + riser1 + riser2
|
||||
Lenovo ThinkSystem SD650-N V2/ SD650-I V3 | untested, but should work | node + riser1 + riser2 + gpus
|
||||
Lenovo ThinkSystem SD665-N V3 | tested, known to work | node + riser1 + riser2 + gpus
|
||||
|
||||
To test if your system *may* be supported, you can run the following command *at your own risk*:
|
||||
|
||||
```
|
||||
$ ipmitool raw 58 50 4 2 0 0 0
|
||||
c4 00 83 a9 cb d3 a2 03 df db 47 6a d8 01
|
||||
```
|
||||
|
||||
Exactly 14 bytes should be returned.
|
||||
In case not or another error occurs your hardware is likely not supported.
|
||||
|
||||
In addition, `ipmitool` typically require 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 ipmitool for Lenovo power readings
|
||||
monitoring ALL = (root) NOPASSWD:/usr/bin/ipmitool raw 58 50 4 2 0 0 0

## `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
|
||||
```
