 ====== The threshold monitor ======
+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]].
-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.
-===== 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 =====
-Threshold manager can be used to set alert-thresholds for data
-sources on specific interfaces, list all thresholds and bulk update
-thresholds.
-It contains an advanced search for choosing netboxes and/or interfaces
-for bulk update.
-It is possible to use both actual and percentage values,- and if an
-alert should be triggered if traffic-load is less or greater than the
-configured value.  Percentage values are is supplied by entering a trailing percent character. Percentage values are only legal when a max-value is defined
-==== List all thresholds ====
-All threshold are listed by supplying the url /threshold/all/.  Thresholds are grouped together by
-netbox-names.
