check_3ware_SSH

The original p_view=289 check_3ware">http://www.nagiosexchange.org/RAID_Controller.58.0.html?&tx_netnagext_pi1p_view=289 check_3ware Perl script works well but I didn't feel like installing nagios on the servers just for one service. Solution: modify the script to run the commands over SSH. This requires a little more setup on your part, though less than setting up nagios :). Usage: 1) Download tw_cli from 3ware's website, install on remote host(s). Make sure you have the right version, might take a few tries to find it. 2) Create //nagios// user on remote host, with home directory. 3) On remote host, edit ///etc/sudoers//. Add the following line to allow nagios to execute tw_cli as root: **{{nagios ALL=NOPASSWD: /usr/bin/tw_cli}}** 4) On local (monitoring) host, generate an authentication key: **{{$ su - nagios}}** **{{$ ssh-keygen}}** 5) Copy the authentication key to the remote host: **{{$ scp /home/nagios/.ssh/id_rsa nagios@192.168.1.15:/home/nagios/.ssh/authorized_keys}}** **- Note: above command assumes the //authorized_keys// file doesn't exist! If it does, you will want to append it.** 6) You can now run the script on a remote host as root with the nagios user on the local (monitoring) host: **{{$ ./check_3ware -C 0 -U 0 -H 192.168.1.15 -u nagios}}** 7) Here's how it looks in //checkcommands.cfg//: **{{$USER1$/check_3ware -C $ARG1$ -U $ARG2$ -H $HOSTADDRESS$ -u nagios}}** **Q:** Why not use check_by_ssh? **A:** I would rather have the script in one place rather than on all the servers. Makes maintenance easier. **A:** I've had problems with check_by_ssh. Of course, that could be attributed to my stupidity ;) **Q:** Do I need //both// scripts, one for local, the other for ssh? **A:** No, to check local, just omit the {{-H}} and {{-u}} options. - //ianar? s?vi//
