Re: [Observium] Could not resolve
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.

Hi, I want to add the host , and Oservium said Could not resolve 10.30.1.1 I check fping & snmp as writed your side.

You're trying very hard to come up with scenarios that people have already given you solutions for.
Observium's target market is primarily service providers and enterprise with large networks.
Many of our SP customers like the features we have which enforce good operational practice.
If Observium works for you and you're not in that segment, that's fine.
However, we can't and won't compromise SP-centric design decisions because users outside of our target market don't like them.
Write a script which takes an Ip, puts a dummy entry in to /etc/hosts and adds the dummy entry. 5 seconds, done.
It's you who need to solve the problem of your unusual use case, not us who need to accommodate it.
There is actually a way to trick Observium in to allowing you to add by IP. I use it for temporary devices, and it most definitely involves DNS. ;)
Adam.

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.

I just want to touch this one point below, and then I’m done.
If you’re running your entire organization on a single DNS server, then you shouldn’t even be working in this industry.
There are certain fundamental components in any network infrastructure that should be redundant. DNS, by far, is high on the list of those components. You should *always* have multiple DNS servers redundant to each other. Maybe even have redundant load balancers front-ending those DNS servers. That’s even more true when you’re hosting/running authoritative DNS servers for certain domains. Whatever NMS you choose to run, even that isn’t as high a priority for redundancy.
It all goes back to good network and server architecture and design. If you don’t have a solid base for all that, then all the higher level stuff is just going to fold like a house of cards. If you spend the extra time to do things right and not half-assed, then you’ll have a solid network and have good reporting on everything. Don’t be that half-ass guy.
