Octet, packet and error  counters are collected, along with CPU and memory statistics ​ (and more). Use the [[sortedstats#​ranked_statistics|"​ranked statistics"​]] (19) to present a list of interfaces with most traffic, the highest error counts, etc. The traffic statistics collection uses [[http://​people.ee.ethz.ch/​~oetiker/​webtools/​rrdtool/​|RRDTool]] and [[http://​cricket.sourceforge.net/​|Cricket]].

   * A flexible [[backendprocesses#​alertengine|alert system]] (9), where each NAV user can adjust his own profile (using [[alertprofiles|the tool alert profiles]], 21) with fine-grained control options. Currently support for sending email, SMS and jabber alerts. The profiles can be made to adjust the volume and types/​severities of alarms wanted, this as a function of time and day of the week.    * A flexible [[backendprocesses#​alertengine|alert system]] (9), where each NAV user can adjust his own profile (using [[alertprofiles|the tool alert profiles]], 21) with fine-grained control options.
