Hi Guys,
I am trying to migrate few services from Nagios Core 3.5.1 to NagiosXI 5.2.7
The Plugins used in the services are written in Perl (i guess as they have .pl extension) those scripts are not working in NagiosXI
e.g

[root@nagiosxi libexec]# ./check_sql-query.pl -u XXXX -p @@@@ -h x.x.x.x -d Monitor -w 0:100 -c 0:250 -s 'SELECT top 1 Noupload FROM Switchmonitor order by TrafficDate Desc' -T MSSQL
install_driver(ODBC) failed: Can't locate DBD/ODBC.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at (eval 3) line 3.
Perhaps the DBD::ODBC perl module hasn't been fully installed,
or perhaps the capitalisation of 'ODBC' isn't right.
Available drivers: DBM, ExampleP, File, Gofer, Proxy, Sponge, mysql.
at ./check_sql-query.pl line 310

Only thing i can see with my novice knowledge is :
At NagiosXI

[root@nagiosxi libexec]# locate ODBC.pm
/usr/lib64/perl5/DBI/Const/GetInfo/ODBC.pm
[root@nagiosxi libexec]#

I have run through google, tried updating Perl by CPAN(Sigh!! know nothing about it just followed some tutorial), had no luck. Thankfully had the snapshot

I am unable to pin point the problem here:S may be it is something with Database or some back-end dependencies (like i said, Novice)
Also there are services for Voice traffic as well to gauge the MOS score and concurrent calls & call failures which i can not move because of this Perl thing.
Can't find any plugin for such in NagiosXI. Services based on perl scripts are working fine in Old Nagios Core.
Can any one please help me here.

Thanks!!

Try:

Code: Select all

yum install -y perl-DBD-ODBC

If that doesn't work can you upload the plugin or provide a link to it please.

Hi Box293,
I will try that and will let you guys know the result.

Thanks

Do I need to install anything else prior to this?

Try this:

Code: Select all

yum upgrade ca-certificates --disablerepo=epel

Then retry the steps I provided previously.

Thanks guys,
Atleast perl thing is not showing up as an error.
But now i am getting this

Could not connect to msdb on MARVIN: [unixODBC][Driver Manager]Data source name not found, and no default driver specified (SQL-IM002)

I copied the odbc.ini & odbcinst.ini with same permissions and owners.
freetds conf file has been replicated too (done all changes with having original file's backup)

Both Nagios are in same network so no explicit rule of access is implied. Both Nagios can ping DB server.

Any thing that i am missing here ???

Can you show us the full input that produced the pasted result above?

Also, from the Nagios machine, please run nmap ipofclientmachine (replace ipofclientmachine as necessary)

Hi,

These are two of the commands (plugins) that are failing in XI and working in Core (I have removed password)

[root@nagiosxi libexec]# ./plugin_capture.pl /usr/local/nagios/libexec/check_sql-jobhistory.pl -h MARVIN -u nagios -p xxxxxx -d 1 -m 2

Could not connect to msdb on MARVIN: [unixODBC][Driver Manager]Data source name not found, and no default driver specified (SQL-IM002)[root@nagiosxi libexec]#

Unknown

nmap results same on both Nagios core and XI

Can you upload the perl script you are using so we can review it?

One thing to look at is the /etc/odbc.ini file on each system.
Look at the working one and add any missing entries to the Xi server and see if that resolves the issue.
