Hi @mohanasundaram ,

You can try to implement a custom datastore consistency check class which will be executed by a scheduler and will run on specific cron expression provided to it.
You can have a look at below link which will give you some idea as what the logic would look like:

    Hi TarunKumar,

    Thanks for sharing input.

    Do we have any method to invoke system/console/jmx service instead of crx/de ?

      Hi @mohanasundaram 

       

      As you mentioned online datastore consistency check, I think you are trying to invoke it from here - https://experienceleague.adobe.com/docs/experience-manager-65/content/implementing/deploying/configuring/consistency-check.html?lang=en

       

      You need to invoke programmatically the JMX Mbean listed in the above document. Here is one example of how you could do this using shell script - https://www.baeldung.com/jmx-mbean-shell-access

       

      In the same script you can add code to send email to configured email address with the response you get from consistency check invocation.

       

      I hope this helps. Please let us know for any questions.

       

      Thanks

      Narendra

          curl -u admin:admin -X POST http://localhost:4504/system/console/jmx/org.apache.jackrabbit.oak^%^3Aname^%^3DSegment+node+store+blob+garbage+collection^%^2Ctype^%^3DBlobGarbageCollection/op/checkConsistency/

           

          This command we can use to execute using script.
