Hello,

after we have upgraded Nagios to the latest version by following this guide,

https://assets.nagios.com/downloads/nag ... ctions.pdf

the upgrade was successfully installed by yum.

One of the checks that are running is failing:

Code: Select all

/usr/local/nagios/libexec/check_mssql_database.py -H [IP] -U report_user -P [PASSWORD] -T [TABLE]

<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.

I've seen there is already a post for this error, so I followed this guide and seen that I have all the components required

yum list installed | grep pymssql
python-pymssql.x86_64          2.1.1-1.el7              @nagiosxi-deps

The only different thing is that pymssql has been installed by yum, I currently don't see pip...but in any case is there.

This check was working correctly before the upgrade, with "check_mssql_database.py" version 1.1.0, and now we have 2.1.1.
So I tried to use the older version but the error is there again.

Any idea to fix it?

Thanks

Hello, @sgargano. I noticed that you're are using the python-pymssql.x86_64 2.1.1 package from the @nagiosxi-deps, while on my server I have python2-pymssql.x86_64 2.1.3 version from the epel repo.

yum list installed | grep pymssql
python-pymssql.x86_64 2.1.1-1.el7 @nagiosxi-deps

[root@centos7x64 libexec]# yum list installed | grep pymssql
python2-pymssql.x86_64 2.1.3-2.el7 @epel

Do you have acess to the epel repo on the server? Can you show me the output of:

yum repolist

@sgargano, Looks like you don't have the epel repo:

!epel/x86_64 Extra Packages for Enterprise Linux 7 - x86_64

You can use this tutorial to install the missing repo:
https://www.cyberciti.biz/faq/installin ... edhat-7-x/

After that run:

yum remove python-pymssql.x86_64
yum update
yum install python2-pymssql

Posted: **Tue Feb 19, 2019 6:00 am**

as suggested we enabled the epel repo,

we had to run this command rather than the one suggested,

Code: Select all

rpm -e --nodeps python-pymssql.x86_64

not to delete nagiosxi as dependcy package.

Now the result is:

Code: Select all

[root@chlug]# yum list installed | grep pymssql
python2-pymssql.x86_64         2.1.3-2.el7              @epel

but even with this right version of pymssql we still have the error reported above.

I did some digging in to this, and found out that the new plugin requires warning/critical values to be added. Can you try running something like this:

Code: Select all

/usr/local/nagios/libexec/check_mssql_database.py -H [IP] -U report_user -P [PASSWORD] -T [TABLE] --warning 1 --critical 5

Did this work?

Posted: **Wed Feb 20, 2019 4:25 am**

No, didn't work.

Our full string we used so far is this:

Code: Select all

./check_mssql_database_1.1.0.py -H [server] -U [user] -P [password] -T [table ]-I [instance] --time2connect -c 0.0001:120

We also tried adding warning and critical but we got the same issue.

Code: Select all

./check_mssql_database.py -H [server]  -U [user]-P [password] -T [table ] -I [instance]--time2connect -c 0.0001:120 --warning 1 --critical 2
<class 'pymssql.InterfaceError'>
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.

you are specifying critical twice

Try

Code: Select all

./check_mssql_database.py -H [server]  -U [user]-P [password] -T [table ] -I [instance] --time2connect -w 0.0001:119 -c 0.0001:120

Posted: **Fri Feb 22, 2019 3:09 am**

I got the same error:

Code: Select all

[root@chlugmw1 libexec]# ./check_mssql_database.py -H SERVERNAME -U USER -P PASSWORD -T TABLE -I INSTANCE --time2connect  --warning 1 --critical 2
<class 'pymssql.InterfaceError'>

Are you running the check against a Windows Server 2016?

Let's check the version of your plugin - run the following command and show the output:

Code: Select all

grep Version /usr/local/nagios/libexec/check_mssql_database.py

What kind of permissions does your user have? Can you log in the MSSQL server as your user, run the following query, and show the output?

Code: Select all

SELECT * FROM fn_my_permissions(null, 'DATABASE')
SELECT * FROM fn_my_permissions(null, 'SERVER')
