warn- and critical level

Hello Supporter,

currently i'm using Nagios 3.3.1 and 1.4.5 plugins. At the moment I'm monitoring around 500 services of different types.
I have added recently another SQL to monitor and it doesn't throw errors. For a german SQL Server Express 2003 I use:

Code: Select all

define command{
	command_name		check_nt_bb_sql_user_connections_german
	command_line		$USER1$/check_nt -H $HOSTADDRESS$ -p PORT -v COUNTER -l "\\MSSQL\$BES:Allgemeine Statistik\\Benutzerverbindungen","SQL Server User Connections: %.f" -w $ARG1$ -c $ARG2$
	}
("MSSQL\$BES" is correct. I checked performance counters on that machine and I have used the same typing for other counters)

along with:

Code: Select all

define service{
	use					generic-service,srv-pnp
	host_name			HOSTNAME
	service_description	SQL Server User Connections
	check_command		check_nt_bb_sql_user_connections_german!10!20
	}
and in the command line it shows me the warn and critical level. for example:

Code: Select all

/check_nt -H IP -p PORT -v COUNTER -l "\\MSSQL\$BES:Allgemeine Statistik\\Benutzerverbindungen","User Connections: %.f" -w 10 -c 20
User Connections: 118 | 'User Connections: %.f'=118.000000%;10.000000;20.000000;
But, in the webinterface it tells me:

Code: Select all

Performance Data:	'SQL Server User Connections %.f'=118.000000%;0.000000;0.000000;
So, I assume the perfdata warning and critical level is gone somewhere, but I have no clue where.

Any ideas?

Try setting your -w and -c values to floats instead of integers. 10.0 instead of 10.

Hello mguthrie,

will try it, thanks for your answer.
Just wondering why it is working with other checks...............

I'm guessing it's an issue with that particular plugin related to data types. int vs float. This isn't so much an issue with Nagios as it is with the individual check plugin returning data correctly.

Hello mguthrie and supporter,

need to raise the issue again. Doing a:

Code: Select all

/usr/local/nagios/libexec/check_nt -H HOSTNAME -p PORT -v COUNTER -l "\\MSSQL\$BES:Datenbanken(_Total)\\Größe der Datendatei(en) (KB)","SQL Server Datafile size total is %.f" -w 150000.000000 -c 200000.000000
results in:

Code: Select all

SQL Server Datafile size total is 115264 | 'SQL Server Datafile size total is %.f'=115264.000000%;150000.000000;200000.000000;
So, it shows my warn and critical level.

Looking in the webinterface, it tells me:

Code: Select all

Status Information:	SQL Server Datafile size total is 115264
Performance Data:	'SQL Server Datafile size total is %.f'=115264.000000%;0.000000;0.000000;
my command definition:

Code: Select all

define command{
	command_name	check_nt_bb_sql_database_file_size_german
	command_line	$USER1$/check_nt -H $HOSTADDRESS$ -p PORT -v COUNTER -l "\\MSSQL\$BES:Datenbanken(_Total)\\Größe der Datendatei(en) (KB)","SQL Server Datafile size total is %.f" -w $ARG1$ -c $ARG2$
	}
my service definition:

Code: Select all

define service{
	use			generic-service,srv-pnp
	host_name		NEXTBB
	service_description	BB Overall DB file size
	check_command		check_nt_bb_sql_database_file_size_german!150000.000000!200000.000000
	}
using the same plugin (check_nt) on other servers and sql services is working fine. for example:

Code: Select all

define command{
	command_name	check_nt_sql_database_files_size
	command_line	$USER1$/check_nt -H $HOSTADDRESS$ -p PORT -v COUNTER -l "\\SQLServer:Databases(_Total)\\Data File(s) Size (KB)","SQL Server Datafile size total is %.f" -w $ARG1$ -c $ARG2$
	}
along with:

Code: Select all

define service{
	use			generic-service,srv-pnp
	host_name		HOSTNAME
	service_description	Overall DB file size
	check_command		check_nt_sql_database_files_size!5500000!6000000
	}
results in corrrect warn + crit level, so perfdata is working.

Do you see any issues? any mistyped words?
Do I have any further debugging options for this particular plugin, or the way to the webinterface?

Anyone an idea what I'm doing wrong?

\\MSSQL\$BES:Datenbanken
Any chance the dollar sign is throwing something off. The $ is a special character for nagios, and typically to have a dollar sign pass correctly you need to use \\$$

You could also try single quotes instead of double quotes so that the shell won't interpret anything inside of them.

Ok, I've tried:

Code: Select all

$USER1$/check_nt -H $HOSTADDRESS$ -p PORT -v COUNTER -l '\\MSSQL\$BES:Allgemeine Statistik\\Benutzerverbindungen',"SQL Server User Connections %.f" -w $ARG1$ -c $ARG2$
using:
check_nt_bb_sql_user_connections_german!150.000000!200.000000
which results in:

Code: Select all

Performance Data:	'SQL Server User Connections %.f'=0.000000%;0.000000;0.000000;

Code: Select all

$USER1$/check_nt -H $HOSTADDRESS$ -p PORT -v COUNTER -l '\\MSSQL\\$$BES:Allgemeine Statistik\\Benutzerverbindungen',"SQL Server User Connections %.f" -w $ARG1$ -c $ARG2$
using:
check_nt_bb_sql_user_connections_german!150.000000!200.000000
which results in:

Code: Select all

Performance Data:	'SQL Server User Connections %.f'=0.000000%;150.000000;200.000000;

Code: Select all

$USER1$/check_nt -H $HOSTADDRESS$ -p PORT -v COUNTER -l "\\MSSQL\$BES:Allgemeine Statistik\\Benutzerverbindungen","SQL Server User Connections %.f" -w $ARG1$ -c $ARG2$
using:
check_nt_bb_sql_user_connections_german!150.000000!200.000000
which results in:

Code: Select all

Performance Data:	'SQL Server User Connections %.f'=120.000000%;0.000000;0.000000;
This is the only check which returns the correct value from the SQL, here "120", but it doesn't pass the warn and critical levels............
The origin name of the instance is "MSSQL$BES", so I assume it is correct to use "MSSQL\$BES".
Also I have passed float values for ARG1 and ARG2, so this is getting odd.
Using this command on the commandline works fine.

Code: Select all

$USER1$/check_nt -H $HOSTADDRESS$ -p PORT -v COUNTER -l "\\MSSQL\\$$BES:Allgemeine Statistik\\Benutzerverbindungen","SQL Server User Connections %.f" -w $ARG1$ -c $ARG2$
using:
check_nt_bb_sql_user_connections_german!150.000000!200.000000
which results in:

Code: Select all

Performance Data:	'SQL Server User Connections %.f'=0.000000%;150.000000;200.000000;

Found a topic which might explaing why I see no warn and critical level (?):
http://forum.centreon.com/showthread.ph ... ce-counter
Got the same issue here.
I think it's because rrd is'nt able to build file(s) with something which has a "%" in the name.
Have to deal with it for now, i didn't find any way to resolve it.
will try a new search and see if I find a solution for that...........
