Could anyone please show me how to create a GROUP in PMM like Zabbix? We can put a class of instances together in zabbix. That make it easy to find the group of hosts. (ps: Grafana is so hard to me:(… i’m reading its doc )
Thanks!
You should read document of Prometheus, Grafana just interface to show graph.
If your host has some rule can follow, you can click EDIT at top or graph, try change instance="$host" to instance=~"^db08.*", mean any host start with db08 will show in graph, it use regular expression.
Reference: https://prometheus.io/docs/prometheus/latest/querying/examples/
Not sure what your query
but i think maybe can use like server=~“backend_0[12]”
