NNMi Log Files

To investigate Network Node Manager i Software (NNMi) performance, or to observe how NNMi processes and services are behaving, you can view log files that show a history of process and service activity. These files are available at the following location:

  • Windows: %NnmDataDir%\log\nnm\
  • Linux: $NnmDataDir/log/nnm

NNMi stores these log files in a name.log file name format. Any archived log file has a number appended to it in the form name.log.%g.

  • name is the log file base name.
  • %g relates to the archive number of the archived log file. The highest appended archive number represents the oldest file.

A log file can become an archived log file after the size of the log file exceeds the configured limit. After a log file exceeds the configured limit, the last active log file is archived. For example, after NNMi archives the nnm.log file as the nnm.log.1 file, NNMi begins logging to a new nnm.log file.

NNMi logs messages at the following logging levels:

  • SEVERE: Events that relate to abnormal NNMi behavior.
  • WARNING: Events that indicate potential problems and all messages included in the SEVERE logging level.
  • INFO: Messages written to the NNMi console (or its equivalent) and all messages included in the WARNING logging level.
