[Nagios-users] Windows Active Sessions
Does anyone know how to return the number of active sessions from a Windows Terminal server? I have installed the NSClient++ service on the Windows server and obviously have the NRPE plugin installed on my Nagios host.

Rab,
if I've understood correctly then you can query a Windows performance counter.
I use an entry in the NSClient++ config file in the [External Alias]
section that looks like this:-
alias_CheckCounter-ts_act_sess=CheckCounter
Counter:sessions=\Terminal Services\Active Sessions ShowAll
MaxWarn=40 MaxCrit=50
Then on the Nagios side, the command is simply check_nrpe -H
thehostname -c alias_CheckCounter-ts_act_sess
So the command definition in Nagios is:-
define command{
command_namecheck_nrpe
command_line$USER1$/check_nrpe -H $HOSTADDRESS$ -u $ARG1$
}
And the service definition looks something like this:-
define service{
use srv-pnp,generic-service
host_name myhost
service_description TS_Active_Sessions
check_command check_nrpe!-c ts_act_sess
notes Number of Terminal Services Active Sessions
contact_groupsnotify-engineers
}
There are lots of similar ways to do this sort of think using
NSClient++. Precisely how you set it up depends a bit on how
obsessive you are about security and your particular preference.
The method shown above means you can have allow_arguments=0 and
allow_nasty_meta_chars=0 in the [nrpe] section which is good for
security. The downside is that if you need to change the warning
theshold, you have to edit the nsc.ini file on the target system.
hth,
Jim

Hi Jim,
Many thanks for the excellent reply. I'll give it a bash and see if I
can get it going.

Re: [Nagios-users] Windows Active Sessions
There's also an existing plugin for this: check_user_count.bat
http://exchange.nagios.org/directory/Plugins/Remote-Access/Count-number-of-terminal-server-sessions/details
However I suggest to use checkCounter, as Jim Avery mentioned it. That way
you keep independent of additional files.

Re: [Nagios-users] Windows Active Sessions
Hi Jim,
Managed to get some output, but not what I expected:
I (0.3.8.75 2010-05-27) seem to be doing fine
I get the same manually running check_nrpe from the Nagios host command
line.
Any ideas?
