SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Update of /cvsroot/mon/mon-contrib/monitors/cisco
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv20934

Added Files:
	cisco-env.monitor 
Log Message:
Added monitor script for testing environmental sensors in various 
cisco devices.  Works in at least 6500 and 3750 series devices.


--- NEW FILE: cisco-env.monitor ---
#!/usr/bin/perl
#
# Monitor Cisco device for certain environmental conditions via snmp
# On devices that export this data, this script will detect and report:
#  - power supply failures
#  - fan blade failures
#  - temperature alarms
#  - chassis minor/major alarms
#
# Can parse monitor-auth.cf for snmp community string, or read from command line
#
# Arguments are:
#
# [-C monitor-auth.cf] [-c community] host [host ...]
