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

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.

Lost all port after svn update

Hi all, Today I did a svn update and afterwords the ./discovery -h none. But now it has marked all the ports as deleted.

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

Linux Agent redesign
by Adam Armstrong 07 Aug '13

07 Aug '13

Hi All, It has turned out that the agent is a little bit difficult to work with, trying to extract data using only shell scripting is a bit of a pain. It's difficult for us to do any form of authentication or encryption, and parsing of the returned data can be a little haphazard because we rely on correct formatting. I've been thinking of alternative designs, possibly using PHP (Perl or Python would probably be better, but they're not viable languages for us) and either an embedded web server or hanging off inetd as it currently does. This would allow us to do encryption, to require some form of authentication and to pass around easier to parse JSON or serialize()'d arrays Personally, I almost always install a PHP CLI interpreter on my servers because I do 'shell' scripting in PHP, but what do the rest of you think? Would you be willing to install php-cli on your servers if you got the ability to do encrypted/authenticated/compressed agent connections? What about if we allowed you to funnel SNMP queries via the agent? (only for UNIX hosts, obviously) adam.

OS/distro version parser
by Adam Armstrong 07 Aug '13

07 Aug '13

Hi All, We're testing a new version of the old 'distro' script used to detect distribution. Please run : ./scripts/os From inside your observium directory on updated installation (you may need to chmod 755 it first). I get: root@alpha:/home/observium/dev# scripts/os Linux|3.8.0-19-generic|amd64|Ubuntu|13.04 root@alpha:/home/observium/dev# The final part is the distro release. Please reply to this post if your distro release is returned as empty. The script might not return a distribution value for non-Linux OSes, this is normal. We're trying to make sure it can always ascertain the distro version and type. Thanks, adam.

Alerting, how to configure
by Rory Schellekens 06 Aug '13

06 Aug '13

Hi all, What is the status of Alerting for Observium? Also I don't see any documentation about it. The main goal is to add our own alarms to Observium. With kind regards, Rory Schellekens
