If you really insist on IP addresses........

Make a hosts file something like this:
10.0.0.1    10-0-0-1.domain
10.0.0.2    10-0-0-2.domain
10.0.0.3    10-0-0-3.domain
etc
10.1.0.1    10-1-0-1.domain
etc

It would be easy to write a script that would spit this out in seconds.
Then all you have to do is use - instead of . in the "IP address" you enter. As long as you have your routing correct, it doesn't matter what device it is or where it is, you'll resolve properly. Your Observium server won't have to wait for DNS to resolve; you don't have to worry about the DNS server being available; all the resolving will be local to the Observium server.


This is such a trivial matter that's been taking up far too much 'bandwidth' on the list.

Hello Everybody,

I would like to give an example, and I want, mainly the developers of observium to think well on this situation.

We often serve temporary events arround, and we need to add this devices for monitoring in somewhere.

Now imagine, every weekend, add to host files, IP address to temporary devices. Ok, use always the same IP. Right. 

In one event we use 5 devices, in another 8.

And what if we have 2 or more events at the same time?

What if my DNS server, that is a monitored server as well fails? 

All my monitoring will stop?

IP address is faster and more reliable than Hostnames.

I would like you to think about adding devices just by hostname. We have 3000 devices on the network that we would like to add. But none of them need registered hostname. For this we have SNMP. They are end devices. They need to be monitored to order history and reports, but do not need DNS Names.

Important devices have the hostname on the DNS, but any monitoring services we used before, we added the devices by hostname. IP is faster.

You cannot add devices by IP address. You need to have working DNS resolution, or have host to IP mapping in your /etc/hosts file.

Hi all,

Been using Observium for a while and love it.  We just added a couple of our ESXI 5.1 servers to Observium in the hopes of being able to monitor bandwidth usage on individual VM's and bill against it.  It polled the physical NIC's but not the virtual ones.  We do have multiple VLAN's too if this makes a difference.  Any way to do this?

Thanks,
