Estimate log volume from Application

New Contributor


I would like to do an estimation of the logs volume generated from Applications to ingest. In order to Reserve  a capacity considering some Application like AntiVirus, Data Base, ...

Is there a procedure to do that? Some calculator online?
thank you

@Lgab_siem So far the only thing I found is an estimation of how much data Azure AD creates per person.  I have not seen anything else.  Hopefully something will come along in the near future as that is a big ask of my customers as well.

HI @Lgab_siem , there's online tools out there that will give you an estimation depending on the log sources. For example:


If you want to monitor a custom built application, I would suggest to redirect the logs to disk and see the size of them over a 24 hour period...that should give you a good idea.



@Lgab_siem Log analytics workspaces have usage table where you can see how much data you are ingesting. I would recommend sending logs for a week and checking the usage for calculation.
