AEM 6.4 | JMX MBean OPTIMAL Threshold value | Email Alert Notification

[rohitp23277067]

Hi all,

We are trying to do analysis on AEM System Monitoring Metrics and wanted to generate Alerts (like Email Notifications). Wanted to collate Optimal threshold value (WARN LEVEL and CRITICAL LEVEL) of each of these MBean Metrics. Meaning if the current value of MBean goes above OPTIMAL THRESHOLD value then email alert will be sent.

Refer this page : https://cqdump.wordpress.com/category/tipstricks/

And in OSGI here we get all System Stats

http://localhost:4502/system/console/jmx/org.apache.jackrabbit.oak%3Aname%3DOak+Repository+Statistic...

Wanted to know if there is any documentation of what should be the RECOMMENDED OPTIMAL .

values for each of these MBean. Below attribute list for your reference :

Thanks for helping.

There are no "optimal values" for these. You can use these values for the purpose of comparing them over time (e.g. to evaluate the effect of optimizations), but it's hard to use them for anything else

Hi Jog,

Thanks for reply on this.

So is there any way to setup email alerts on current values of these parameters. I wanted to use ACS Common Health Check E-mailer to send health check reports with just current values of these parameters.

ACS Common Health Check Emailer provides the input field to add hc.tags. Below are the only fields. Is there a way to do this ?

Have you checked its documentation already (https://adobe-consulting-services.github.io/acs-aem-commons/features/healthchecks/status-emailer/ind...). Any questions should be covered there.
