Nagios Support Forum

Hello Nagios Crew,
I hope you are all doing well.
So I am having some problems with the check_mssql_database.py script.

when launched I get the following error:
/usr/local/nagios/libexec/check_mssql_database.py -H <x.x.x.x> -U 'username' -P 'password' -I 'instancename' -T master --datasize --critical 10
<type 'exceptions.TypeError'>
Caught unexpected error. This could be caused by your sysperfinfo not containing the proper entries for this query, and you may delete this service check.

Is there any solution?

Thanks

Can you look at the following link to make sure the MSSQL prerequisites are installed on the server?

Another cause is in newer versions of the Microsoft database, some of the default settings were removed which causes some of the checks to fail with that error.

Third cause could be cause by a permission issue with the user account on the MSSQL server. If you can setup the account as a read only DBO account, that is usually sufficient enough for the check to run.

Hi
I have checked all your suggestions but still am unable to execute.

Which version of SQL Server are you running this script against?

Another question, what are the user permissions set to in the MSSQL database?

The MS sql versions we are using are:

we have 2 farms with different versions Mssql 2012 and Mssql 2014
User permission on our user is sysadmin
Consider that with the same credentials we are able to successfuly execute the other check_mssql_server.py script (I do not know if this can be relevant)
Thanks

I believe the check fails as you don't specify a warning threshold. Try running: Are you getting the expected output now?

Hi lmiltchev
Ok it works!
The only way to avoid the warning is to filter it in the messages?
I also have now this check that is failing:

/usr/local/nagios/libexec/check_mssql_database.py -H <IP> -U 'xxxUSER' -P 'xxxPASS' -T 'master' -I <Instancename> --logcachehit --warning 0:95 --critical 0:97
<type 'exceptions.ZeroDivisionError'>
Caught unexpected error. This could be caused by your sysperfinfo not containing the proper entries for this query, and you may delete this service check.


All other checks are working now.


Thanks

You can set up warning and critical thresholds to be the same:

I also have now this check that is failing:

/usr/local/nagios/libexec/check_mssql_database.py -H <IP> -U 'xxxUSER' -P 'xxxPASS' -T 'master' -I <Instancename> --logcachehit --warning 0:95 --critical 0:97
<type 'exceptions.ZeroDivisionError'>

I believe that in order to make this particular check to work, you would need to set up the user account on your MSSQL server with Server Role = sysadmin. Can you try fixing the permissions, and let us know if this helped?

Hi lmiltchev,
the strange thing about the logcachehit check I am trying, is that all other checks on the same db work as you can see in attached image. mssql.jpg.

User permissions account on my MSSQL server has Server Role = sysadmin.

if warning and critical have the same value will 2 messages/alerts be sent?
