Folder monitoring in Dynatrace

[rajdeepan03]

Hi,

is there any way to perform the folder monitoring using Dynatrace OneAgent and what are the different ways of achieving it?

Thanks,

Deepan

What we did is we have scheduled a cron job on OS every 1 hour to submit a metric via REST API or OA ingest interface with "1" or "0" values if a folder/file we wanted to be is there.

See details:

Depending on what you need, there is an option to use a oneagent extension for monitoring files.  We use an extension that checks:

• number of files matching one of configured file wildcard patterns
• file modification time for files matching wildcard patterns

And the extension creates a Dynatrace problem opening event when the number of files is higher than expected or a file has not been modified in a defined period.

If you are interested, please tag me in this thread and I'll be happy to provide it.

Hey @DanielS / @Radoslaw_Szulgo  / @rajdeepan03 

you can find the extension including code here:
https://github.com/TEMPEST-a-s/Dynatrace-OneAgent-File-Change-Extension 

To use it, just download the file named custom.python.filechange.zip from the release and upload it in your Dynatrace environment and deploy it to OneAgents where required.

I think it's quite straightforward to configure, but nevertheless here is a screenshot of the configuration:

You can add any number of wildcard patterns and you can also modify the problem even text and title message and use placeholders.

This is an example of problem created when old files are found:

Hope this helps someone 😀

Activate the latest version from the in-product hub. It auto distributes itself to hosts based on tags/host groups/management zones and such. It also has a wizard look instead of the previous format.

In order to resolve the error problem, I just installed the package (libxcrypt-compat) in linux 

as I have an error : while loading shared libraries: libcrypt.so.1: cannot open shared object.

"To use it, just download the file named custom.python.filechange.zip from the release and upload it in your Dynatrace environment and deploy it to OneAgents where required."

The file system monitor extension in the in-product hub can maybe resolve the use case without manually distributing anything. You can find the instructions on how to use it by searching for the extension in your tenant.
