Observium without DNS
by observium＠velder.li 09 Aug '13

Hi, I think it would be a good idea if it's possible to use observium without dns, or to overwrite the hostname used to get snmp data. I have some devices with internal and external IP adresses, and I'd like to use the internal IP for polling, but the external hostname for the device itself. Comments? Regards, Patrick

Go with the fastest processor cores you can find to make the web interface feel faster, especially with a lot of ports. Though, your install doesn't sound all that big... Adam.

If a device is marked down, it'll tell you if it was because of ping or snmp in the eventlog. Either way, if you are having devices continually marked as down, it's an indicator of poor network connectivity or dodgy firewalling. Adam.

Snmppings
by Ryan Milton - MVS USA 08 Aug '13

One thing about Observium, that I find frustrating, is that devices that are definitely up, that are definitely pingable with no drops still show as occasionally being off-line, or down. Sometimes this is worse, or better depending on SVN version. The only remedy seems to be that I have to stop monitoring device. What good is that? Are there any other things that I can do to look and tweak? Sent from my iPhone

Graph Legend
by Colin Anderson 08 Aug '13

08 Aug '13

When viewing the graphs for a switch it cuts off the names of the interfaces in the Legend (such as "FastEthern") making it so you can't tell one interface from another. Does anyone know if this can be adjusted in the code so it is able to output longer interface names? Sample output screenshot: [cid:image001.png@01CE9454.EBF02270] Thanks in advance, Colin Anderson

bah re: override DNS
by Rob VanHooren 08 Aug '13

I think it would be a *terrible* idea for observium to work without dns. the fact that bofh Adam has pretty much forced it, is a very welcome sledgehammer against the sloppiness of incomplete node deployment habits. ditto with pingability imo. just be glad he didn't make A and PTR records have to match each other (and ^sysName$ too!) ... or at least have an extant PTR, something that is often overlooked. count your lucky stars; the only reason he probably didn't (yet?) is that it might have slowed things down a smidge. /grin/ worse, he could have run through checks against the entireties of rfcs 1122 and 1123, or also compared sysLocation against a LOC record query, before a node gets accepted. ps … perhaps some CNAME wrangling might work suitably for your case. split-horizon views in bind would do the trick for sure. for inspiration, have a chew through http://backreference.org/2010/02/01/geolocation-aware-dns-with-bind/ cheers, R.

crossbar history
by Peter Childs 08 Aug '13

08 Aug '13

6500/7600 chassis show the crossbar usage in details pane, and I see c6kxbar-1-0.rrd type files on the file system, but hovering over the crossbar bit doesn't show a historical graph, and I can't seem to see a historical graph in any of the other tabs for the device. Am I missing something, or just a site-specific issue? Cheers, Peter

Graphs not generating in Observium
by Mail List 07 Aug '13

07 Aug '13

Hi, We have an issue with our new Observium installation. We have performed an Ubuntu SVN install. All required packages and dependencies were installed and configuration steps followed. We have added many devices through Observium interface. However the graphs are not getting plotted. I couldn't find anything coming under the folder "/opt/observium/graphs". root@observe:/opt/observium/graphs# ls root@observe:/opt/observium/graphs# Can you please let us know what could be the issue and help us to correct it? Regards Joby
