Hello, can you support on how to proceed on the "files age, creation or modification monitoring"? just get notification.
There are agent metrics for that, e.g.
File.Time.Modify(/etc/passwd)
https://www.netxms.org/documentation/adminguide/appendix.html#file-time-modify
Metric would return unix time.
First thing is to create Data Collection Item on a node with that metric.
Then you can add threshold, if you need a notification when modification time changes, you can use function "Diff with previous value", operation "!= : not equal to".
Then rule in event processing policy is needed, we can discuss this later on.
