Can dynatrace monitor the open-file-count?

Hi,

Some workaround could be create a Request Attribute that counts how many times a method that "opens a file" has been invoked.

AFAIK OneAgent does not collect this metric for processes. But it would be quite straightforward to write a OneAgent plugin for that (at least for Linux) - just by counting the number of files in /proc/PID/fd for each individual process.


To access /proc for a custom process you should be root but Dynatrace runs plugin under unprivileged dtuser account.

This is on the road map tentatively scheduled for sometime in Q4.


Hi Dave, is there any update on this?


I have not heard anything but just left a question on our internal Slack about this and will let you know if I hear back on it.

If you create a custom chart and search for "handle", there are now some good candidates:
