Error description

  • Environment: The Monitoring Agent for UNIX OS 6.2.2 on HP
    
    On HP-UX the Monitoring Agent for UNIX OS kuxagent process
    takes a very long time and generates high cpu usage when it
    tries to resolve tty names using major/minor IDs.
    
    tty names should be cached in order to reduce CPU usage.

Problem summary

  • The kuxagent process has performance issues in resolving TTY
    names for processes.
    
    The Monitoring Agent for UNIX OS kuxagent process takes a very
    long time and generates high CPU usage when it tries to resolve
    TTY names using major/minor IDs.
    

Problem conclusion

  • The fix uses a cache for the resolution of TTY names related to
    each process.  The environment variable TTY_REFRESH_TIME that
    can be specified in the configuration file ux.ini allows the
    user to set the refresh time in minutes for the cache.  If the
    environment variable is not specified, the agent uses the
    default refresh time of 60 minutes.  Specifying
    TTY_REFRESH_TIME=0 results in the cache not being used at all.
    
    
    
    The fix for this APAR is going to be included in the following
