Details about NNMi Logs
Can someone give me an explanation of the following logs. What they log, when to look at them, etc?
Also, can someone tell me the difference between nnm.log and nnm-trace.log? In version 10.X they were differentiated by the CONFIG log level, but this level isn't in the 2018.X documentation anymore.
Much Appreciated. Thank you.
Re: Details about NNMi Logs
Contains a history of the health report. Looking at our 2018.11 system shows that a report is saved at 12 pm and 12 am. As it contains many statistics it can be used to analyze previous values (e.g. for JBOSS memory usage) if NNMi detects a health problem.
Currently not on our system, but it should be the log file from the installation, when the database is created. Not needed later.
The main log file while NNMi is running. You should check it for errors and warnings.
These files are used in Application Level Failover and cluster environments.
The content is very similar to what is logged in nnm.log, but when you enable tracing, you will need this file.
It logs some starting parameters of the jboss server.
It contains messages about starting, status and stopping NNMi processes (ovstart, ovstatus, ovstop). You should look here when a NNMi process does not start or stop.
The difference between nnm.log and nnm-trace.log is obvious when you enable tracing. Without that, nnm-trace.log has not more use as nnm.log.
BTW: In most cases I look at boot.log (when NNMi is starting I check that no errors are shown), then I look at nnm.log and as most customers are using auto actions I have an eye on incidentActions.0.0.log (in sub folder public).
HTH and best regards
