Hello @Alok_Pal,
This alert is created under the resource Browse › YOUR_SERVERl SAS Environment Manager Data Mart 9.4 › APM ETL Processing.
If you click on the Inventory, you will see that the resource ( config/Lev1/Web/SASEnvironmentManager/emi-framework/bin/master_apm_etl.sh ) runs nightly and it gives a warning if runs for more than 30 min, and an error if more than 1 hour.
In your case, the nightly process has run probably more than 30 min and the availability went down to 50%.
I would not be too concerned about it, but perhaps also it is a signal that it will need a review sooner or later.
To know more on what is going on, I would recomment you to run the same command manually and see what is going on:
master_apm_etl.sh -dv (optionally, you can also include the parameter --evdebug LEVEL)
