[Nagiosplug-devel] MSSQL plugin ?

[Jonathan Rozes]

I cobbled a plugin together that uses sqsh (http://www.sqsh.org), which can
be built using freetds. Here's a quick rundown of the setup:

1. Install and test sqsh.

2. Install the plugin included below in the plugin directory of your nagios
installation and name it 'check_mssql'.

3. Create a file called '.sqshrc' in the nagios user's home directory with
contents like so:

\set username="USER"
\set password="PASS"

Where USER and PASS are the username and password needed to access the MS
SQL server, respectively. Make sure the nagios user has permission to read
the file (and probably nobody else unless you want to give away access to
your SQL server). Using a read-only account is recommended.

4. Create a file called 'sqsh-NAME' (where NAME is the host_name used in
your nagios config for this server) in some directory that the nagios user
can access (like /usr/local/nagios/data or somesuch) with some SQL
statements that constitute a simple check, like a SELECT from a small table
in each database, like so:

use mydatabase;
select * from mytable;
use myotherdatabase;
select * from myothertable;

5. Setup a command entry in your config like so:

define command{
	command_name	check_mssql
	command_line	$USER1$/check_mssql -H $HOSTADDRESS$ -f
/usr/local/nagios/data/sqsh-$HOSTNAME$
}

You may want to add '-c' and '-w' arguments to change the warning and
critical runtime thresholds as well. Run 'check_mssql -h' for complete usage
instructions and default values.

6. Setup an appropriate service entry in your config.

7. Check your config, restart nagios and enjoy.

The plugin is attached. I make no claims of portability, warranty, etc., so
know what you're doing before doing it.

Good luck,
jonathan
