I am trying to get Prometheus Alerting UI to report in on two metrics
procstat_memory_vms{process_name="ovs-vswitchd"} / mem_total{host=~"cmp.*"}
From the above I get the good ol' "No data points found", however I need to try and find out how to find the ratio of the total process memory a VM consumes to the total memory on the compute host.
Basically whats in use by VMs / Total Compute Host Memory.
I have verified that both above are integers and the intersting thing is that both produce integer numbers...while if I use a fixed value for the
mem_total{host=~"cmp.*"}
It works, however I want to account for this dynamically without using a fixed value for the
mem_total{host=~"cmp.*"}
Any thoughts?
