Thanks @Nagendra_Prasad and @Venkata_Kasi_Viswanath_Mugada1 for sharing the information!
Looks like CCE REST APIs are not straight forward, it is tricky to use.
Apart from schedulers, if I have other IS components to monitor as well. I don’t think it will give the output as I expected. (Example: It is not showing whether Scheduler is disabled or enabled which is important for monitoring)
@Venkata_Kasi_Viswanath_Mugada1 I have gone through the steps given for UM REST plugin. I am not able to see the plugin tab in enterprise manager to configure it. (for step - 4.Select the tab Plugins from the interface configuration panel.)
as per this link, looks like license is required for plugin feature set. Can you please confirm on this.
