| - | The threshold monitor in NAV 3 uses data from NAV's RRD database, and the RRD files generated by Cricket, to check for and report interfaces with high load, high CPU and related events. At the moment there is no interface to easily adjust the threshold values. However, this is under development. | + | ====== The threshold monitor ====== |

| - | ====== Operation ====== | + | |
| - | ThresholdMon runs as a cron-job. At run-time, it fetches all the thresholds in the RRD database and compares them to the datasource in the corresponding RRD file. If the threshold has been exceeded, it sends an event containing relevant information. | + | |
| - | + | ||
| - | ====== Filling thresholds ====== | + | |
| - | As mentioned above, there is no easy way to edit a threshold value. A script exists to set each data source's threshold value to a default value, unless one has already been set. This script is located in ''$NAVINSTALL/bin'' with the name ''fillthresholds.py''. To change the predefined threshold value, edit the config file for this script. It is located in ''$NAVINSTALL/etc'' with the name ''fillthresholds.conf''. Enter a percentage value here, which will be set on every data source when ''fillthresholds.py'' is run. | + | |
| + | The threshold monitor is a simple cron job, which will monitor the RRD statistics that have threshold values set. Threshold values can be managed individually and in bulk using the [[thresholdmanager|Threshold Manager]]. | ||
