3.1. Part 1: Monitoring your first node

So ... you have succeeded installing your first SANET :)

Now... let’s try to bring it into life, and let it monitor your first node (that could be any host in your network).

Export the environment variable SANET_HOME pointing to the directory where SANET is installed (this is the directory containing the manage.py file. By default it is /usr/local/sanet):

$ export SANET_HOME=/my/path/to/sanet

Import the definition of the GNU/Linux server category:

$ bin/sanet-cli < share/contrib/category-server-linux

For this use case we chose localhost because ... there’s no place like localhost !

We suggest you to have an SNMP agent up and running and answering to requests for a specific community (say public) originated by localhost, after that you can finally configure SANET to monitor your node:

• Choose the appropriate number of threads for your installation (default is 10)

• Execute bin/sanet-cli and paste the following configuration::

  conf term
  site threads 4
  node-category server-linux
   router
   target reach-server
   exit
   target rootfs category storageperc
    parameter storage_descr "root fs"
    parameter storage_re ^/$
   exit
   measure rootfs-graph category storage
    parameter storage_descr "root fs"
    parameter storage_re ^/$
   exit
   target cpuperc-hr
   exit
   measure cpu-hr
   exit
   target reboot-hr
   exit
   target ramperc-ucd
   exit
   measure ram-ucd
   exit
   measure swap-ucd
   exit
   target swapperc-ucd
   exit
   target loadavg category loadavg-threshold-ucd
   exit
   measure loadavg-graph category loadavg-ucd
   exit
   target nonidle-ucd
   exit
   measure nonidle-graph-ucd
   exit
  exit
  node localhost
   category server-linux
   icon host
  exit
  exit

• Start the Poller process by executing etc/rc.sanet start. Take a look at var/poller_log to make sure there are no problems...

• Start the Web User Interface with etc/rc.sanet web.

• Point your browser to http://<yourhostname>:7777/sanet/ and enjoy your first SANET installation !

3.1.1. Bonus section: deploy your installation with Apache

• Install Apache server version 2.x
• Check that your Apache server is up and running
• Get your SANET Apache configuration with etc/rc.sanet deploy apache. You’ll get the configuration fragment ready to be put in your apache.conf along with some symlinks that you need to put in your DocumentRoot.
• Restart your Apache server with apachectl restart.
• Point your browser to http://<yourhostname>/sanet/

Once you have suceeded setting up basic monitoring, go on to Part 2: Configuring checks in your first GNU/Linux node to learn how to setup and customize new checks and notifications.
