problem with newly created checkcommand andservice

[Kaplan, Andrew H.]

Hi there --
 
The command definition for database_connection-time is the following:
 
define command {
                command_name                        database_connection-time
                command_line
/usr/local/nagios/libexec/check_mssql_health --server=<database>
--username=<username> --password=<password> --port=<port> --mode=connection-time
 
There are arguments that are passed to the command. I did not remove the
exclamation point due to another command that also has 
arguments passed to it. For example:
 
define command {
                command_name                       check_nis_server
                command_line
/usr/local/nagios/libexec/check_nis -H <server> -d <domainname>
 
has the following definition in the services.cfg file:
 
define service {
                service_description                   Check NIS Service
                check_command                      check_nis_server!
                host_name                             <server>
                check_period                          24x7
                notification_period                   24x7
                contact_groups                        linux-admins
                event_handler_enabled                 0
                active_checks_enabled                 1
                passive_checks_enabled                0
                notifications_enabled                 1
                check_freshness                       0
                freshness_threshold                   86400
                use                                   generic-service
 
One thing I came across so far. I had imported the configuration files into the
NConf utility database of the Nagios server. Among the files that were imported
was the
commands.cfg file. During the importation process, the commands.cfg file data
was imported into a field called checkcommands. When the NConf utility was
subsequently
used to generate new files, a checkcommands.cfg file was among the them. 
 
This file, along with the original commands.cfg file, is located in the
/usr/local/nagios/etc/objects directory. However, the nagios.cfg file does not
reference it. One idea that 
I had was to remove the reference within nagios.cfg to commands.cfg, and replace
it with a reference to checkcommands.cfg, and see what are the results.
 
What do you think?

Hi,

Please show the command definition of database_connection-time.

Furthermore in the service definition you use the following line:

check_command                   database_connection-time!

Didn't you want to pass arguments to the command? If they're already hardcoded
in the command definition you can leave the exclamation mark off.

	Hi there --
	
	I am going through the motions of adding a new checkcommand, and service
to the Nagios server. The command involves 
	the check_mssql_health plugin which runs on the Nagios server. The
plugin gets in information via queries to a particular 

	port on the Microsoft SQL server. Here are its particulars: 

	/usr/local/nagios/libexec/check_mssql_health --server=<database server>
--username=<username> --password=<password> --port=<port> --mode=connection-time


	The name of the checkcommand is: database_connection-time
	
	Once the checkcommand was created, so was the service. The configuration
of the service in question, taken from the 
	services.cfg file, is shown below:
	
	define service {
	service_description                     Database Connection Time
	check_command                   database_connection-time!
	host_name                               <database server>
	check_period                            24x7
	contact_groups                          nt-admins,linux-admins,admins
	event_handler_enabled                   0
	active_checks_enabled                   1
	passive_checks_enabled          0
	notifications_enabled                   1
	check_freshness                         0
	freshness_threshold                     86400
	use                                     generic-service
	}
	
	To verify the new configuration would work, the command: 

	/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
	
	was run to verify the configuration. It was here the error message: 

		Checking services...
		Error: Service check command '<database>_connection-time'
specified in service 'Database Connection Time' for host '<database server>' not
defined anywhere!

	I verified the syntax of the command in the checkcommands.cfg file,
including the name given to the command. Why would Nagios 

	think the service check command is not defined, and return this error?
