Log4j log monitoring

[Ozzy]

The Microsoft Monitoring Agent has limitations they refer to as "criteria" which must be adhered to in order for it to successfully collect logs (see https://docs.microsoft.com/en-us/azure/azure-monitor/agents/data-sources-custom-logs) i.e. log rotation not supported which is the default of Confluence and Jira. ( Servers are also on Azure Vm.s)

log4j in Jira and Confluence out of the box does not support the requirements (or at least I am not experienced enough to figure it out).

Is there any tools or solutions for this ? We need to collect our logs here but our workaround of "appending the contents to a single file for each day from which Microsoft Monitoring Agent is able to collect logs successfully and upload " causes too much IO in the system and causes performance problems & crashes for jira & confluence. 

Any suggestions  ? How can we send these logs to Azure shortly? 

Kind regards,
