| ====== The threshold monitor ====== | ====== 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 ===== | + | |
