Atlantis ILIO Center<\/a> can monitor <\/strong>the health and availability of ILIO Session- and Replication hosts<\/a>. If necessary ILIO Center sends alerts via SMTP (aka Mail) or via a SNMP trap <\/strong>(push). However, if the ILIO Center experiences an unexpected shutdown or network connectivity is lost, a SNMP trap is never sent (or in case of lost of network connectivity: the monitoring system does not receive the trap).<\/p>\n

Additional monitoring can be done via ping<\/a> or by monitoring the state of the VM. However, verifying the availability of a machine via ping could result in false-positives and not each monitoring system can monitor the state of a VM, therefore you might want to monitor via SNMP polling (pull).<\/p>\n

A vanilla installation of Atlantis ILIO (Center) does not have an SNMP<\/a> agent installed, therefore I wrote a script that can push the agent and\/or update the configuration. You can find the download <\/strong>at the bottom of this article.<\/em><\/p>\n

<\/p>\n

Packages<\/h1>\n

The script is assuming that the ILIO appliances are not<\/em> <\/strong>connected to the internet so the packages (the redistributables) are included <\/strong>in the download.<\/p>\n

Each product + version is a separate appliance, the version of some packages (like perl) differ. Therefore different versions of net-snmp<\/a> are installed.<\/p>\n\n\n\n\n\n\n
Product<\/strong><\/td>\nVersion<\/strong><\/td>\nnet-snmp version<\/strong><\/td>\n<\/tr>\n
Atlantis ILIO Center<\/td>\n4.0.19<\/td>\n5.4.3~dfsg-2_amd64<\/td>\n<\/tr>\n
Atlantis ILIO for Diskless VDI<\/td>\n3.2.0.5<\/td>\n5.4.3~dfsg-2.7_amd64<\/td>\n<\/tr>\n
Atlantis ILIO Persistent VDI
\nSession and Replication Host<\/em><\/td>\n		4.0.0.1<\/td>\n5.4.3~dfsg-2.7_amd64<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

If you have a newer version and the script doesn\u2019t work, please run dpkg \u2013l and mail me the output.<\/em><\/p>\n

The benefit of including the packages in the script is that it\u2019s fast(er) and an internet connection is not required. The downside is that if Atlantis updates their appliances with a different Linux of Perl version, the script might need to be updated.<\/p>\n

 <\/p>\n

Configuration<\/h1>\n

A default configuration is applied allowing all machines <\/strong>to query only system and hrSystem group data using the community string public <\/em>(default). The configuration is stored in the snmpd.conf<\/em> file (see examples<\/a>) included in the download.<\/p>\n

For instance you might want to change the default<\/p>\n

 rocommunity public default -V systemonly<\/pre>\n
to<\/p>\n
 rocommunity mysecret 10.0.0.1 -V systemonly<\/pre>\n
to set the community string to mysecret<\/em> and only allow host 10.0.0.1<\/em> to query the appliance. If you want to retrieve additional information, like processor, disk or memory usage, you might want to remove -V systemonly<\/span>.<\/p>\n
The script is build so you can easily push the new configuration to your ILIO Center, Session- and Replication hosts.<\/p>\n
 <\/p>\n
Distribute and install<\/h1>\n
To use the script you need to upload the content of the archive (for download see the bottom of the article) to your ILIO Center machine using SCP (for instance WinSCP<\/a>).<\/p>\n
    \n
  1. Connect to your ILIO Center machine via SCP<\/li>\n
  2. Upload the files to \/opt\/Support\/snmp<\/li>\n
  3. Enable the eXecution bit<\/a> for InstallSNMP.py (0744)<\/li>\n<\/ol>\n
    \"\/opt\/Support\/snmp\"<\/a>\"InstallSNMP.py<\/a><\/p>\n
     <\/p>\n
    To run the script you need to setup a terminal session via SSH and execute the InstallSNMP.py script.<\/p>\n
      \n
    1. Connect to your ILIO Center machine via SSH<\/li>\n
    2. Change the directory to \/opt\/Support\/snmp<\/li>\n
    3. Execute the script .\/InstallSNMP<\/li>\n<\/ol>\n
      \"2013-06-14<\/a><\/p>\n
       <\/p>\n
      Usage<\/h1>\n
      On execution the script will first ask you if you want to install (or update the configuration of) SNMP on the ILIO Center machine<\/strong>.<\/em><\/p>\n
      \"Install<\/a><\/p>\n
      Next it will ask if you want to update the other ILIO hosts (Session- and\/or Replication hosts<\/a>). If yes, the script will ask for the master password. If you don\u2019t have a master password (the passwords are not equal for all hosts) just leave it blank, the script will ask for the password for each host.<\/p>\n
      \"Install<\/a><\/p>\n
      As mentioned in the previous chapter, in case SNMP is already installed (and running) the installation is skipped and only the new configuration is applied.<\/p>\n
