I use prometheus to monitor our network share drive. and I feel SingleStat panel is very good,
but I have question, Instead use a hardcode value in the Gauge → Max filed, can I use a query, for example something like
node_filesystem_size{device=~“wdknas01”}
so I don’t need to reset the value when I have a new harddisk.
If SingleStat couldn’t do that, any idea which panel could fit my need?
