I'm using the check_nt to get exception rates from a Windows machine

/usr/local/nagios/libexec/check_nt -H vmnavca2test5 -s "" -p 12489 -v COUNTER -l "\\.NET CLR Exceptions(*)\\# of Exceps Thrown / sec","Exceptions per sec, rate" -w 50 -c 100

in NagiosXI using the check_xi_service_nsclient "Check command" from the dropdown.

The check is successful and returns

Exceptions per sec = 0.00 rate | 'Exceptions per sec'=0.000000 rate;50.000000;100.000000;

Even though the Perfdata seems to be present, I'm not seeing expected rrd file

I'm seeing some related items in the perfdata.log for this check for other hosts with the following:

2022-02-06 21:46:34 [15202] [2] Processing Line 286

similarly in the service-perfdata, I'm haven't been able to capture for the specific host but I see for others

DATATYPE::SERVICEPERFDATA TIMET::1644183935 HOSTNAME::otherhost SERVICEDESC::.NET Clr Exceptions per sec SERVICEPERFDATA::'Exceptions per sec'=0.000000 rate;50.000000;100.000000; SERVICECHECKCOMMAND::check_xi_service_nsclient!!COUNTER!-l "\\.NET CLR Exceptions(*)\\# of Exceps Thrown / sec","Exceptions per sec, rate" -w 50 -c 100!!!!! HOSTSTATE::UP HOSTSTATETYPE::HARD SERVICESTATE::OK SERVICESTATETYPE::HARD SERVICEOUTPUT::Exceptions per sec = 0.00 rate

I checked for the hosts I'm seeing in service-perfdata and perfdata.log, the graphs don't show up either. None of the hosts/service with this service check are graphing results.

Searched high & low to try and find a solution but no luck. Any help on next steps to investigate or better yet resolve would be greatly appreciated.

Thank you,

Please attach the RRD and XML file for this service from that directory so I can review them.

What version of XI are you using? You can grab it from the bottom left hand side of the web interface after logging in.

I can't post those files as they don't exist, I wish they did. That's part of the issue describe.

Running Nagios XI 5.8.5

Sorry about that, I misunderstood.

Try changing it to this:
- It's a counter so you want c and I removed the space from it as well

Code: Select all

/usr/local/nagios/libexec/check_nt -H vmnavca2test5 -s "" -p 12489 -v COUNTER -l "\\.NET CLR Exceptions(*)\\# of Exceps Thrown / sec","Exceptions per sec,c" -w 50 -c 100

That worked! A great many thanks.

Spoke too soon but it made progress. Now, getting:
RRDs::update ERROR /usr/local/nagios/share/perfdata/somehost1/.NET_Clr_Exceptions_per_sec.rrd: not a simple unsigned integer: '0.000000'

By using "ops" as the unit, the system interpreted it as a GAUGE and then it displayed properly. The UOM isn't ideal but at least now we're graphing data.

The solution was:

/usr/local/nagios/libexec/check_nt -H vmnavca2test5 -s "" -p 12489 -v COUNTER -l "\\.NET CLR Exceptions(*)\\# of Exceps Thrown / sec","Exceptions per sec,ops" -w 50 -c 100

Interesting, I didn't know ops did that.

But now I see my mistake, I got confused by you checking a COUNTER (which is c), it's really the per sec that makes it a gauge.
