This "how-to" covers how to monitor and graph a Windows performance counter in op5 Monitor.
Monitoring the performance counter
In perfmon, select a performance counter that you want to monitor and/or graph. In this example we monitor and graph the following performance counter:
Performance object: Terminal Services Session
Instance: Console
counter: Thread Count
Request the counter-value from command-line to verify access and to examine the returned data:
# /opt/plugins/check_nt -H 192.168.1.8 -v COUNTER -l "Terminal Services Session(Console)Thread Count"
20
(in this example the returned value is an integer with a value of 20)
To monitor this counter in op5 Monitor, just add the following check-command and service:
| command_name: | check_nt_tsc_threadcount |
| command_line: | $USER1$/check_nt -H $HOSTADDRESS$ -v COUNTER -l "Terminal Services Session (Console) Thread Count","TS Console Thread Count is: %.f" -w $ARG1$ -c $ARG2$ |
| service_description: | Terminal Services Console Thread Count |
| check_command: | check_nt_tsc_threadcount |
| check_command_args: | 25!30 |
