[Nagiosplug-devel] NSCLIENT "Malformed request or internal error. Check EventLog:Non e&2&1"

[Schindewolf, Stefan, Infraserv-Hoechst/DE]

Hello.

The problem occurs with NSCLIENT 1.07.1
I received the following error, that has been concerning several people on
the list:

The command line is something like: "/usr/local/nagios/libexec/check_nt -H
$HOSTADDRESS$ -v CPULOAD -l 1,85,95,5,75,85,15,55,75"
The output is: "Malformed request or internal error. Check
EventLog:None&2&1"
The output of event log is: "Division by zero"

We tracked it down to line 250 in uNSCLIENT.pas:
REQ_CPUTOTAL: FindAnswer:=
IntToStr(CPUBuffer.GetAverage(StrToIntDef(asArgv[2],60)*12));
It must be the GetAverage call because everything else could not raise this
exception.

We suppose CPUBuffer.GetAverage is a win32 api call !?
Can we sue MS for that "division by zero" stuff?

On some hosts (running service pack 2) there is no problem.
We tried to call the windows performance counters directly
(""/usr/local/nagios/libexec/check_nt -H $HOSTADDRESS$ -v COUNTER ...")
but are only receiving either 100% or 0% CPULOAD, depending on our
parameters.

Has anyone a clue how to workaround it?

Thanks in advance and best regards.
