Hi All,

Facing issue while configuring Check_mssql_health plugin on following.

OS-CentOS Linux release 7.2.1511 (Core)
Nagios - Nagios Core 4.2.1
check_mssql_healt - check_mssql_health $Revision: 2.6.4.7 $ [http://labs.consol.de/nagios/check_mss_health]

-----------------------------------------------------------------------------------------------
While executing following command using root and nagiosn users, on command line it is giving correct output. but on nagios configuration it is giving error.

Command-
./check_mssql_health --server DBNAME --mode connection-time --username 'USERNAME --password 'PASSWORD' --commit

Result

OK - 0.01 seconds to connect as USERNAME | 'connection_time'=0.01;1;5;;

Nagios Error

Service State Information
Current Status: CRITICAL (for 1d 11h 3m 10s)
Status Information: CRITICAL - DBD::Sybase initialisation failed: Can't locate object method "driver" via package "DBD::Sybase" at /usr/lib64/perl5/vendor_perl/DBI.pm line 820.

Perhaps the capitalisation of DBD 'Sybase' isn't right. at /usr/local/nagios/libexec/check_mssql_health line 6245.

Plesase help to get this fixed, I have already spent time to get this fixed.

Thanks in advance.

Regards,
Milind Chafekar.

You'd probably have better luck contacting the people who maintain that plugin since we didn't write it.

Did you follow a particular guide for installing the Perl dependencies? If so, can you share that guide with us?

Can you also share the CLI command that produced the error? It's not immediately clear since the only command I see is producing an OK result based on the context of your post.

Thanks Matt for the reply, I have followed the suggested installation document. and configure the plugin in the command and widows cfg files.

On the command line I could see the correct expected output

Code: Select all

[nagios@monitor-nobo libexec]$ ./check_mssql_health --server testdb --mode connection-time --username 'nagiosadmin' --password 'password' --commit
OK - 0.01 seconds to connect as nagiosadmin | 'connection_time'=0.01;1;5;;
[nagios@monitor-nobo libexec]$

but on the nagios page showing following error.

        command_name    check_mssql_health
        command_line    $USER1$/check_mssql_health.pl --server testdb --mode $ARG1$ --username ''nagiosadmin' --password 'password' --commit
        }

Service Defination

Code: Select all

define service{
        use                     generic-service
        host_name               Test_DB
        service_description     DB Connection Time
        check_command           check_mssql_health!connection-time
        }

I will also try to coordinate with the plugin manager team.

This sounds like a global environment issue.

This KB article shows an example of how to fix it. In your case I think you need your path statement to include the location of the DBI.pm file.

Even though the KB article is for Nagios XI it still applies to Nagios Core.
