I'm not aware of such software. Zimbra automatically generates reports and send them to the admin account (by default).
Also, you could give this a try https://github.com/Zimbra-Community/zimbra-elasticstack
If you install the latest ES version (7.3 at this time), you'll have a little problem when importing the template as ES changed some things and are now enforcing some previously depricated features. It is an easy fix as you only have to remove the _doc type from the template (you could see other defaults templates and compare it to see). Sorry the vague description, I can't remember now which exact word needs to be removed from the template (i could swear is the _doc), but you'll figure it out quite easy I'm sure.
