SAS Application Server Tier in Environment Manager

[Nigel_Pain]

SAS 9.4M7 on Windows Server 2012 R2. Four servers (Metadata, compute, mid-tier, LASR)

I had a few issues with Environment Manager this morning so restarted the server and agents. Since then it has been showing an availability issue for the SAS Application Server Tier. I suppose I don't really know what this one is. The documentation suggests that it is something to do with the metadata server. Does anyone have an idea how I troubleshoot this further? All other monitored resources seem to be OK. 

Thanks

The SAS Environment Manager Agent on the middle-tier machine is the agent that discovers the SAS Application Server Tier resource.  If you have problems with discovering or monitoring that resource, check the agent.log on the middle-tier host.  If there are no clues in there, you can set the following logger in agent.properties to get more information:

log4j.logger.com.sas.emi=DEBUG

You will need to restart the agent after setting DEBUG.

agent.log is located at <sas-configuration-directory>\Lev1\Web\SASEnvironmentManager\agent-5.8.0-EE\log

agent.properties is located at Lev1\Web\SASEnvironmentManager\agent-5.8.0-EE\conf

This link provides more information about the SAS Application Server Tier plugin:  https://support.sas.com/rnd/emi/SASEnvMgr/plugin/sas-appserver.html

Thanks. I'd found that bit of the documentation but there's not a lot of detail there.

There are regular warnings appearing in the agent.log but they don't seem to have anything to do with the SAS Application Server Tier. I might schedule a reboot overnight to reset everything. It quite often works. If not, I'll try your debug suggestion.

Well rebooting didn't help. I turned on debugging for a while but I can't really make head or tail of it. I think it's a case for TS. I'm off for the next fortnight but will raise a track when I'm back. I'll report back on what comes from that. Thanks @ronf_sas for your input,

Hello
Can you explain this a bit more clearly ?

"Since then it has been showing an availability issue for the SAS Application Server Tier"

[Nigel_Pain]

Environment Manager shows Availability of the Application Server Tier as 0%:

Have you looked at the agent.log yet?

Search it for "SASAppServerTierMeasurementPlugin". 

If you don't get anything useful, set DEBUG in agent.properties by adding:

log4j.logger.com.sas.emi=DEBUG

You will need to restart the agent after setting DEBUG.

agent.log is located at <sas-configuration-directory>\Lev1\Web\SASEnvironmentManager\agent-5.8.0-EE\log

agent.properties is located at Lev1\Web\SASEnvironmentManager\agent-5.8.0-EE\conf

Then search agent.log for SASAppServerTierMeasurementPlugin

I did try that but couldn't make much of it. Anyway, I've raised a track with TS so hopefully they can help.

As usual TS came up trumps:

1. Delete the SAS Application Server Tier in Environment Manager.

2. Stop EV Agent using CMD.

3. Rename Ev Agent /data directory 

4. Start EV Agent using CMD.

The EV agent then rediscovered the SAS Application Server Tier resource and started monitoring it properly.
