I stopped the development of this Plugin in 2015 due to move from Nagios to Check_MK. This Nagios plugin was created to check OracleVM state. What could be checked? Currently there are 3 Checks implemented: - filesystem Checks used space in the filesystem and returns a Warning or Critical - server Checks the state of the server. Result is CRITICAL when server is not in 'Running'-Mode WARNING when Server is in Maintenance-Mode - vm Checks the state of the virtual machine. Result is CRITICAL when VM is not in 'Running'-Mode There is some statistical data for the virtual machine like RAM and CPUs. The data in '()' are the allowd maximum values while running the vm.

This Nagios plugin was created to check OracleVM state.
What could be checked? Currently there are 3 Checks implemented:
- filesystem Checks used space in the filesystem and returns a Warning or Critical Example: check_ovm3 -p secret -a filesystem -n fs_Samsung_750GB -w 51 -c 75 -H localhost OK - Filesystem Used Space 40% in fs_Samsung_750GB warn(51) crit(75) |pctused=40; Total=698; Used=281
- server Checks the state of the server. Result is CRITICAL when server is not in 'Running'-Mode WARNING when Server is in Maintenance-Mode Example: check_ovm3 -p secret -a server -n ovm3server -H localhost OK - ovm3server is Running ovs-release 3.2.1-494 Processors 3 OVM-Server-IP 192.168.100.200 Maintenance Mode=Off Memory=16.0 emory Dom0=0.82 CPU-Type=AMD Phenom(tm) II X3 705e Processor CPU-Speed=2.494557
- vm Checks the state of the virtual machine. Result is CRITICAL when VM is not in 'Running'-Mode There is some statistical data for the virtual machine like RAM and CPUs. The data in '()' are the allowd maximum values while running the vm. Example: check_ovm3 -p secret -a vm -n rac1 -H localhost OK - rac1 is Running on ovm3server Repository=Samsung_750GB HA-Mode=No CPUs 3(3) RAM 1500(3000) OS=Oracle Linux 6 Dom-Type=Xen PVM
Requirements: - OracleVM 3.1.1 or newer This plugin only works with OVM3.1.1 or newer. Older versions doesn't have the new SSHCLI Some Details are missing when running under Version 3.1.1.
- expect this plugin needs expect on the machine where the plugin is started http://expect.sourceforge.net/ The executable for expect must be at /usr/bin/expect - expect for OracleLunux5 wget http://mirror.centos.org/centos/5/os/x86_64/CentOS/expect-5.43.0-8.el5.x86_64.rpm yum install -y --nogpgcheck expect-5.43.0-8.el5.x86_64.rpm
- SSH-Connection to OVM-Manager on Port 10000 The informations are gathered with the new OVMCLI. The connection is done over Port 10000 (Default Port from OVM-Manager for SSHCLI)
- Password for admin is required The connection is done with password to the SSHCLI. There is a stupid restriction in OVM-Manager that makes public key authentication in monitoring impossible. The password is visible when executing the script on the process list!
- ssh-hostkeys are not stored this is needed because some NRPE-Servers are unable to write the known_hosts => Connections are imposibble. :-(
Can you please advise? ./check_ovm: line 457: [: =: unary operator expected
Great little plugin. I needed more option(checking repository) and the code was written very well so I could easily hack at it and add the additional check!
We are just switching to OVM 3 so your timing couldn't be more perfect. When testing it out, I noticed that it won't properly read filesystems if the name has spaces in it. I've tried wrapping it in quotes to no avail. I'm trying to modify it to accept the UUID of the filesystem instead, at least until my bash is good enough to get around what I'm guessing is a variable substitution issue.
