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

Stefan,

I too have that problem which seems to be very intermittent. If I reduce 
the number of checks or rasie the time between checks then it seems to get 
better. 

Unfortunately I am not much of a programmer to help - but if you should 
find a way around, please let me know !!

Thanks

Matthew

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






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.
