Occasionally, randomly, a server will display the red error message "The Server Intelligence Agent for this server is unavailable". We only know it happens when we stumble upon it by looking at the properties of the server in the CMC. Otherwise, the SIA is running per the CCM and other servers in the same node don't display the message. The same can be said for the status of the 'bad' server and it's state as it will display 'Running' too.
Only resolution is to restart the SIA.
What we want to know is why this happens and how to alert us so we know that it did happen and possibly automate the resolution if restarting is the answer. I should mention we are on BI 4.1 SP5.
Thanks, everyone!
Is this a single server or part of a cluster ?
If cluster - its a networking issue, if single server - something is crashing periodically or your CMS is loosing connection to CMS DB.
You'll need to enable trace on SIA, CMS and those servers that often have this and then review those traces.
This is a clustered environment with 2 CMS nodes, 5 Reporting/Processing nodes, and 3 Web Servers. Only thing is, as of now, I haven't noticed a pattern or determined a server that has received the error any more times than another.
in that case it is most likely a networking issue between servers or DB connectivity to CMS DB from CMS servers and SIA's....
Need to get DBA involved and network team.
One of the thing to prevent this issue in time, its check the resources of the servers (i mean, RAM avalible, DiskSpace), and create some notifications in Monitoring Area, in CMC to check the state of this particular server.
