Observium > Cannot retrieve processor/memory data from host

  • 772

I have successfully setup an Observium monitoring server on a AWS EC2 instance to monitor other EC2 instances running Ubuntu.

Hosts has been added successfully.

I can run

snmpwalk -v1 -c public 171.32.10.1

And get some output. In Observium dashboard, for each host I can see poller/system information, even data about Nginx status is working but nothing about:

  • processor
  • memory
  • storage

Should I install or configure something to achieve it?

  1. Problem was on other host side, by default, the SNMP client configuration gives basic information. You must edit /etc/snmp/snmpd.conf and be sure of:

     rocommunity public  default

    That's it, I got plenty of data now!

    I have written a small tutorial:
