We have OpenNMS integrated with Grafana through HELM. We are monitoring CPU average for the nodes by creating a variable for Nodes.
But when a single node is not having the CPU data due to SNMP Issues, then the total dashboard is giving error and we are not able to see any data for the remaining servers.
We had influxDB also in our environment, in which if a single server is not sending data then we can see the other data from other servers.
Is it possible for HELM too in grafana, as it is not possible to manually select the nodes and then add the nodes whenever it is added in OpenNMS.
