hello,
librenms has a storage.storage_perc_warn field in the database, a lnms config:set storage_perc_warn command to set a default and the ability to personalize the values for some particular filesystem/disk.
I use all the above for warning alerting of disks filling-up (with a custom SQL alert rule);
it would be nice to also have a storage.storage_perc_crit field too for emergency alerts on disk almost full.
You can just create an alert rule with the percentage you want.
yes, I have the rule, but it’s a static rule and it’s not very clean to personalize single filesystem critical limit adding code and exclusion inside the rule.
