Ssh – Zenoss: Getting SNMP stats over SSH

monitoringperformance-monitoringsnmpsshzenoss

I have the SSH connection working. I have it successfully modeling the device (Ubuntu Server, in this case).

What I can't get to work is the SNMP portion. It sounds like I have to custom add the snmpwalk command when doing monitoring over SSH – in other words, have Zenoss connect via SSH, and then run an arbitrary command against the client (in this case, an snmpwalk), and then parse the results.

What I need help doing is:

  1. Add the snmpwalk command to the SSH monitoring
  2. Parsing the output and getting the data back into the charts

I'm not sure if I understand the question, but when I was doing SSH modeling, I had trouble getting device information back from the server. I had to do the following:

  • Setup SSH Key based authentication (I created a user name zenoss on the remote machine, and disabled the password)
  • Install the ZenPlugins on the remote machine: http://sourceforge.net/projects/zenoss/files/zenplugins/zenplugins/ I also had to install the PythonSetupTools for my distribution.
  • Change the modeler plugins. Remove zenoss.snmp.* plugins, and add the corresponding zenoss.cmd.* plugins (for linux, osx, etc)
  • Remodel Device.

My exact commands for a remote CentOS/RHEL 5 based device were:

wget http://sourceforge.net/projects/zenoss/files/zenplugins/zenplugins/Zenoss-Plugins-2.0.4-1.py24.noarch.rpm/download
rpm -i Zenoss-Plugins-2.0.4-1.py24.noarch.rpm 
wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c7.tar.gz#md5=dedbf6a4f71cd6deaf13ee885054f16b
tar zxvf setuptools-0.6c7.tar.gz
cd setuptools-0.6c7
python ./setup.py install
cd /usr/lib/python2.4/site-packages/
chmod 775 setuptools*

Hope that helps.. Took me quite a while to figure out.
