Thresh - a Data-Directed SNMP Threshold Poller

摘要

Thresh is a simple SNMP monitor, written in Scotty (Tcl 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) and trending and history tools (such as Cricket).
