AW: NSCLIENT "Malformed request or internal error. Check EventLog:Non e&2&1"

[Scholten, Thomas]

Hello Stefan,

i just solved this error by using the lodctr Tool. May be lodctr
c:\winnt\system32\infoctrs.ini could help to restore the counters. For
sanity you should check before with the perfmon Tool if the Processor
Counters are avaiable. In this case check the mails of Sandro Vaz who has
posted some more hints in this list.

hope it helps

Thomas

Betreff: [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.
