Observium Free Network Monitoring Solution

Observium Free Network Monitoring Solution

Ensure all Wireless Access Points, Switches, Routers, and Bridges are setup with SNMP community in Read-Only and has location set to the location of the servers.

snmp-server community <community> RO 1
snmp-server location <cocation>
snmp-server contact <contact>

Ensure all Wireless Access Points, Switches, Routers, and Bridges have a DNS entry on your DNS server so that Observium can automatically detect all devices via DNS and auto-add to the system. 

Update the Ubuntu DNS servers (Observium uses DNS to pull names and switches)

Install resolvconf package

sudo apt-get install resolvconf

Update DNS servers using resolvconf package

Run

cd /etc/resolvconf/resolv.conf.d
sudo cp -p head head.orig  #backup copy, always do this
sudo nano head

The top of the file is a scary warning. The file /etc/resolv.conf is autogenerated from the contents of this file; the warning is there so it will get put in /etc/resolv.conf when /etc/resolv.conf is generated. To the end of the file, add

nameserver <ip_of_nameserver>

Press Ctrl x and answer yes to saving the file. To finish up, regenerate /etc/resolv.conf so the changes are applied right now:

sudo resolvconf -u

Then check the contents of /etc/resolv.conf to see the line you added is now there. Further, it will still be there the next time your machine boots or your network service is restarted, whichever comes first.

Update the hostname on the system

hostname <FQDN of the server>

/etc/init.d/networking restart

hostname

hostname -f

shutdown -r now
