OCNRF Alert Configuration

Follow the steps below for OCNRF Alert configuration in Prometheus:

Note:

By default Namespace for OCNRF is ocnrf that must be update as per the deployment.
The ocnrf-config-1.2.0.0.0.zip file can be downloaded from OHC.
Unzip the ocnrf-config-1.2.0.0.0.zip package after downloading to get NrfAlertrules.yaml file.

Take Backup of current configuration map of Prometheus:

kubectl get configmaps _NAME_-server -o yaml -n _Namespace_ > /tmp/tempConfig.yaml

Check and Add NRF Alert file name inside Prometheus configuration map:

sed -i '/etc\/config\/alertsnrf/d' /tmp/tempConfig.yaml
sed -i '/rule_files:/a\  \- /etc/config/alertsnrf' /tmp/tempConfig.yaml

Update configuration map with updated file name of NRF alert file:
```
kubectl replace configmap _NAME_-server -f /tmp/tempConfig.yaml
```

Add NRF Alert rules in configuration map under file name of NRF alert file:

kubectl patch configmap _NAME_-server -n _Namespace_--type merge --patch
"$(cat ~/NrfAlertrules.yaml)"

Note:

The Prometheus server takes an updated configuration map that is automatically reloaded after approximately 60 seconds. Refresh the Prometheus GUI to confirm that the NRF Alerts have been reloaded.
