UNKNOWN: No handler for that command.

[Remc0]

Hi Michael,

We are upgrading our NT domain to a Windows 2008 R2 domain, so it is also time to upgrade our nsclients to the newest 0.4.x version. But testing with that I ran into some problems.

I have some counters I want to check so I set them up like this:
Btw; those counters work in the 0.3.9 version.

[/settings/external scripts/alias]
COUNTER_CONTEXT_SWITCHES=inject checkCounter ShowAll "Counter:ContextSwitches=\System\Context Switches/sec" ShowAll MaxWarn=35000 MaxCrit=45000
COUNTER_PAGES=inject checkCounter ShowAll "Counter:Memory pages/sec=\Memory\Pages/sec" MaxWarn=300 MaxCrit=500
PROC_QUEU_LENGTH=inject checkCounter ShowAll "Counter:Processor queu length/sec=\System\Processor Queue Length" MaxWarn=10 MaxCrit=15
CHECKTASKS=inject CheckTaskSched "filter=exit_code ne 0" "syntax=%title% (%most_recent_run_time%)" warn=>0 

But when I run them I get these errors in the logfile:

2012-06-21 15:41:57: e:..\..\..\..\trunk\modules\CheckSystem\PDHCollector.cpp:148: Failed to query performance counters: \238(_total)\6: PdhGetFormattedCounterValue failed {format: 1024}: -2147481642: A counter with a negative denominator value was detected.


2012-06-21 15:41:59: e:..\..\..\..\trunk\include\nscapi\nscapi_core_wrapper.cpp:181: No handler for command 'COUNTER_CONTEXT_SWITCHES'.
2012-06-21 15:42:00: e:..\..\..\..\trunk\modules\CheckSystem\PDHCollector.cpp:148: Failed to query performance counters: \238(_total)\6: PdhGetFormattedCounterValue failed {format: 1024}: -2147481642: A counter with a negative denominator value was detected.

When I look further up in the log, I can see this at initialisation:

2012-06-21 15:41:17: e:d:\source\nscp\trunk\modules\checkexternalscripts\commands.hpp:91: Failed to parse arguments for command 'COUNTER_CONTEXT_SWITCHES', using old split string method: unknown escape sequence: inject checkCounter ShowAll "Counter:ContextSwitches=\System\Context Switches/sec" ShowAll MaxWarn=35000 MaxCrit=45000

So it's about the \ escaping character. Could you allow this, or give me an option how I can use the \ character?

[mickem]

My guess is the problem is the very old "inject" keyword which has been migrate to the newer format which is causing the problem.'

The \ failure has a fall back so it will parse it in the old way.
But it should be key=command not key=inject command...

(So this should not work in 0.3.9 either unless by misstake)

I changed it, but no luck.

CHECKTASKS=CheckTaskSched "filter=exit_code ne 0" "syntax=%title% (%most_recent_run_time%)" warn=>0

And under modules I have:

; CheckTaskSched - CheckTaskSched can check various file and disk related things. The current version has commands to check Size of hard drives and directories.
CheckTaskSched = 1

Error generated in the log file

Do you have any more ideas/suggestions?

[mickem]

Humm...

Could you paste the full config?
It sounds to me that everything is correctly setup so maybe a bug somewhere?

I think this was due to case insensetive issues added in 0.4.0 which ahs been fixed in 0.4.1

[Remc0]

Tested it with 0.4.1.57 and the issue is indeed fixed.
