Hi @TarunKumar  I don't see that path even on SP20 but the Health Check(/libs/granite/operations/content/healthreports/healthreportlist.html) console is loading completely fine.

Is there any option like /etc/replication/treeactivation.html(which was there in the Classic version) under Cloud Service of AEM? If there's NO direct link/url, is there any way to achieve this? Thanks,

After the SP21 upgrade, I've seen the 'NO resource found' error at https://<IP>:<PORT>/system/sling/monitoring/mbeans/org/apache/sling/healthcheck/HealthCheck/asyncIndexHealthCheck.json which was completely fine on SP20.  Has anyone faced this issue?
