HAC Logs

In most cases the HAC log files and alarms together with the element diagnostics data provide enough information to find out the cause of the problem. The information is mainly in plain English. If a problem occurs repeatedly, you can temporarily switch the HAC logging level to the tracing or debugging value to get more detailed information.

HAC Log Files

Each HAC node produces event logs to its local disk, and by default they are stored to system’s log file directory of the system $VU_HOME$\logs. HAC creates a new log file each day with the date in the name of the file.

Most of the entries have the following syntax:

  1. A time stamp.

  2. An optional priority:

    • INF => Information

    • WRN => Warning

    • ERR => Error

    • DBG => Debugging information

    • TRC => Tracing information

  3. The element.

  4. The change.

  5. The reason for change.

HAC Element Diagnostics

Each HAC node produces diagnostics information about its local elements. To get the diagnostics, right-click the HAC node in the IA tool’s system model view, and choose Get Remote Diagnostics.

The requested diagnostics data is opened into a separate window.
