Hi All, Root level (canvas) Controller Services - We tend to setup several Root level Controller services for developers that are typically DBCPConnectionPools and DistributedMapCacheClientService and maybe a few other. MOST importantly, these controller services cannot be down and cannot be disabled - must remain Enabled at all times.
We have now had a few outages where upon examination a Controller Service has encountered “something” that caused it to be Disabled or Down. Is there a standard practice we can use to “Monitor” the controller services and ensure we get alerted if any one of them goes into a Disable state? What do folks generally think is a good monitoring practice? We are on HDF Version 3.4.1.1.
