The Disk Quota Monitoring page in Virtualmin is a very useful tool to be alerted when domains are approaching or exceed their alloted quota. However, when setting it to check on a reasonably frequent schedule, such as hourly, it becomes very annoying to get so many alerts, and as a result they often get ignored.
It would be a nice addition if we could specify thresholds for these alerts instead of getting an e-mail on every check. For example, send e-mail when the quota exceeds 80, 85, 90, 95, and 100%. Currently, if a domain exceeds 80% (as we have it configured), we get notified every hour until they drop back down below that amount. These hourly notifications can go on for many days or weeks if the usage doesn't decrease.
In other words, we want to know right away when a domain is in jeopardy of reaching their quota, so we don't want to set the checks to every 24 hours, but we also don't want to keep getting the same alert every hour unless there is a notable change.
