The alarm history viewer is called from the NEM Desktop via the menu “Fault Management – Alarm History”.

For the alarm history, a date / time window can be specified which may span the whole history period. The viewer then automatically collects the appropriate data from all existing and relevant history files. Data can be additionally filtered and sorted if required, and then sent to a printer, or be exported to a file.

The files produced are in .csv or .xml format. They can be imported into a spreadsheet application for further analysis.

The event log is called from the NEM Desktop via the menu “System – Event List”. This Event List only shows events that haven’t yet been pushed to the event history files. If events do not appear any more in the Event List, you need to check the event history files “/opt/nem/var/log/events_yyyymmdd.txt”. The default prefix “events” of the log files can be modified via the system events configuration file “/opt/nem/voyager/etc/eventlogmanager-system.properties”.

The event list can be filtered e.g. for the event time being before a certain date and time. Data in the Event List can be further sorted and sent to a printer, or be exported to a file.

The files produced for export are in .csv or .xml format. They can be imported into a spreadsheet application for further analysis.
