Thresh--A Data-Directed SNMP Threshold Poller

John Sellens, GNAC, Inc.


Thresh is a simple SNMP [1] monitor, written in Scotty [2] (Tcl [3] with the Tnm extensions), which uses the UNIX file system hierarchy for configuration and data storage. Thresh compares SNMP variables to per-device thresholds or values, and issues notifications if any current SNMP variable values are unacceptable (or unexpected). Thresh can be used by itself, or as a complement to other network management and monitoring tools. Thresh can be thought of as fitting in between tools that generate immediate emergency alerts (such as Big Brother [4]) and trending and history tools (such as Cricket [5]).
