# RAPL Daemon
|
||
|
|
|
||
|
|
This runs a server that is capable of changing the percentage at which
|
||
|
|
a node is being throttled to using RAPL. This daemon should be installed
|
||
|
|
on all worker nodes.
|
||
|
|
|
||
|
|
### Sample payload for testing:
|
||
|
|
```
|
||
|
|
curl --header "Content-Type: application/json" \
|
||
|
|
--request POST \
|
||
|
|
--data '{"percentage":75}' \
|
||
|
|
http://localhost:9090/powercap
|
||
|
|
```
|
||
|
|
|
||
|
|
### Payload
|
||
|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"percentage":75
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
### Response
|
||
|
|
|
||
|
|
The daemon will respond with a json payload containing zones that were
|
||
|
|
successfully capped as well as the zones that were not capped.
|
||
|
|
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"cappedZones": null,
|
||
|
|
"failedZones": [
|
||
|
|
"intel-rapl:0",
|
||
|
|
"intel-rapl:1"
|
||
|
|
],
|
||
|
|
"error": "some zones were not able to be powercapped"
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Field error will not exist if failed zones is empty.
