Alert for missing disc mounts?

[shakib]

Is it possible to create an alert when a disc mount is unmounted on a Linux host? When I go to the custom disk-detection rules section I do not see an option for disc mounts specifically. What would be the best way to go about setting such an alert?

We just implemented it last week and tested it today for NFS mount. We created a custom alert with 1mb free space and generate an alert if no data is available, polling 2 mins out of 5 mins. In the payload we selected disk.entity

Hi,

Please help to elaborate on how the metric event is configured and how it helps to generate alert when an disk is unmounted ?

[mrc15816]

Create a metric event on available space for that mount point let us say 100 KB, so this will trigger in an event a mount got dropped. Hope this helps.

@Vidhyasagar,

Or you should try this extension:

Filesystem monitoring | Dynatrace Hub

I hope it helps.

Best regards,
