[ https://ovirt-jira.atlassian.net/browse/OVIRT-2972?page=com.atlassian.jir... ] Shlomi Zidmi commented on OVIRT-2972: ------------------------------------- Actually we are monitoring [resources.ovirt.org|http://resources.ovirt.org] in Prometheus, and should have caught this on time !prom.png|width=83.33333333333334%! Looking at the alert rules defined, i see the following: {noformat}node_filesystem_free_bytes / node_filesystem_size_bytes{device!="tmpfs"} < 0.1{noformat} The blue line (/dev/sdb - mounted on /home/jenkins) in the picture is slightly above 0.1, and that’s why no alerts were fired. I’ll readjust the threshold so that Prometheus would be able to catch similar issues sooner next time. -- This message was sent by Atlassian Jira (v1001.0.0-SNAPSHOT#100133)
