Database Question
by Letz Stefan / ACS 18 Nov '11

18 Nov '11

Hello List, we use observium to monitor about 200 network devices including syslog, ipsec, and smokeping. What we see is an excessive growing off database every time we make an svn update. Could everyone else see this phenomen?

Billing question
by Berant Lemmenes 17 Nov '11

17 Nov '11

I have a quick question to confirm what data is used to determine an overage... I believe I'm understanding the code/database correctly in that it calculates the 95th percentile for both in and out (rate_95th_in/rate_95th_out) and then whichever one is larger is stored as rate_95th and that is what is used for the value that the overage is based on. I just ask because we see ~4-5 times more entries that are over their limit with Observium than with our previous system (which granted was horribly cobbled together, and last maintained in the early 00's), and I just wanted to make sure it wasn't taking the sum of in and out for the calculation. Thanks! Berant

This is currently by design. We could do with something to make it prettier though.

Cisco ASA Remote Access Sessions getting Error Drawing Graph
by Jeff Collyer 15 Nov '11

15 Nov '11

Using Observium to monitor several pairs of Cisco ASA 5520 firewalls. On the graphs/firewall page /observium/device/device=27/tab=graphs/group=firewall/ the very last graph is labeled Remote Access Sessions. I'm getting the ubiquitous "Error Drawing Graph" on that row of graphs. whats my next debugging step? The apache logs don't show any errors, so I'm guessing its somewhere in the Observium or RRDtool layers. Observium 0.11.11.2726 Apache 2.2.14 (Ubuntu) PHP 5.3.2-1ubuntu4.10 MySQL 5.1.41-3ubuntu12.10 Thanks ---- Jeff

Potential bugs - r2726
by Berant Lemmenes 15 Nov '11

15 Nov '11

Some of these could be known issues but I didn't see anything in the bugtracker and wanted to see if they were somehow unique to my installation. There are a couple pages that completely error out, the browser get's a failure trying to load. For me that is the main Inventory page under the overview tab, and the all ports page. I have currently 30 devices with ~16k ports in my system. For a page like the all ports page I would expect that to take some time to render as it's pulling together a lot of info for 16k interfaces, however after maybe 1-2 seconds it fails. Filtering under the traffic bills page doesn't seem to work, when I first started entering Bills I know I was able to filter by over/under quota, however now that I have 67 in it doesn't seem to work. Also I'm not sure what the 'All Customers' drop down is supposed to filter on as I've filled out all the customer/bill related fields when adding a new bill and it never populates. In general I don't see any place to look for clues as to what is failing on the page failures, as the apache error.log doesn't have anything and the observium.log file is only poller items. Can I enable more verbose logging into the observium.log file somehow? Thanks, Berant

Anyone else suddenly have their toner MIB / graphing charts go straight to 0 / nan%?? Can't be sure when it started happening... can only say it used to work... Experienced in svn v2705... Just updated to v2714 to see if its fixed... Cheers, Matt

Hey Adam, What OID is used to generate stat about non-unicast packet, does these below correct? 1.3.6.1.2.1.31.1.1.1.2 1.3.6.1.2.1.31.1.1.1.3 1.3.6.1.2.1.31.1.1.1.4 1.3.6.1.2.1.31.1.1.1.5 I'm trying catch some error in stat which cause to show as 500M non-unicast packets, which is damn huge.

Re: [Observium] dlink snmp
by Adam Armstrong 12 Nov '11

I see this reasonably often on cheaper kit. Lots of dell switches do it too. You can disable poller/discovery modules with hyte web interface. Perhaps disable them all then enable one by one to see which it is? Adam. Nikolay Shopik <shopik(a)inblock.ru> wrote: >Hey, > >Does anyone here monitor D-link switches via SNMP?

New user introduction - Scaling questions
by Berant Lemmenes 11 Nov '11

11 Nov '11

Hello everyone, I just wanted to introduce myself to the list and complement the authors on a fantastic tool! As a little background on our deployment, I work for a Midwestern US ISP/NSP and I found Observium by looking for a replacement solution for our severely aging 95th percentile burstable billing system. However I was blown away by Observium once I got it running. We're now looking at replacing several systems with it focusing on interface/data polling, we have a separate system that we will continue maintain to do SNMP trap handling. Right now we have just shy of 16k interfaces across 30 nodes, with another dozen or two to add to complete our cisco L3/L2 devices. I'm interested in adding new device types for our Cisco 15454 SONET and MSTP systems (and have read the Developing/NewOS document), however if these devices were to be added it would take our device count up north of 600, with a massive increase in interfaces. So I want to make sure I've got things setup well before going down that road. While performance is doing great thus far I'm concerned about things I can do to scale the system. Currently the system is a Xen VM with 4 cores and 4GB of ram, and the load average is staying right around 4 with 40% average CPU usage. Since we're not interested in alerting for interface/node up/down with Observium I've configured each device to ignore and disable alerting. I've also took out the various menu items poller modules for things that we don't need as well. And I need to look into interface names that can be ignored etc as well. I've not yet tried rrdcached but I'd like to see what impact that has on existing load. Does anyone else have any recommendations or additional best practices? I have some thoughts ideas on potential features that could be useful for other ISP users as well, however I don't want to flood the list right off the bat with an even more rambling email. Observium is a great tool, and though I'm not a programmer I'd love to help out however I can. Thanks, Berant
