8 Configuring Alerts

To configure Alerts:

Note:

In the below procedure, _NAME_ is the Helm Chart Release Name and _Namespace_ is the Prometheus NameSpace.

1. Execute the following command to take backup of current config map of Prometheus.

   kubectl get configmaps occne-prometheus-server -o yaml -n occne-infra > /tmp/tempConfig.yaml

2. Execute the following commands to add UDR alerts file to the Prometheus configmap yaml file.

   sed -i '/etc\/config\/alertsudr/d' /tmp/tempConfig.yaml

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

3. Execute the following command to update the Prometheus configmap yaml file with updated UDR alert file name.

   kubectl replace configmap occne-prometheus-server -f /tmp/tempConfig.yaml

4. Execute the following command to add the UDR alerts rules in configmap under UDR alert file name.

   kubectl patch configmap occne-prometheus-server -n occne-infra --type merge --patch "$(cat ~/UdrAlertrules.yaml)"

   Note:

   Prometheus server takes updated configmap reloaded after sometime automatically (approximately 20 sec).
