Hi,
I use Prometheus with the node_exporter added the query to monitor available diskspace.
100 - ((node_filesystem_avail_bytes{instance=~"$node:$port",job=~"$job",device!~‘rootfs’} * 100) / node_filesystem_size_bytes{instance=~"$node:$port",job=~"$job",device!~‘rootfs’})
This give me multiple mounts such as /home /tmp et cetera.
My question: How can I modify the quesry so onle /tmp is monitored for example.
