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

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

dlink snmp
by Nikolay Shopik 11 Nov '11

11 Nov '11

Hey, Does anyone here monitor D-link switches via SNMP? We had small devices which is pooling just fine, with pretty limited support, but still ok. And now trying out DGS-3120-24TC and it seems dying under snmp load when you add it on observium. And by dying I mean it become bunch of useless metal until you reboot it. So I wonder maybe anyone know which OID cause such behavior.

Anyone using 95th Billing?
by Mahomed Hussein 03 Nov '11

03 Nov '11

Hi Is anyone using 95th billing in observium? I've been having slowness issues with it, so I setup a new server, downloaded the latest version and cleared all the billing tables and let it start polling again. This was fine and the polling has been working. The page was loading in less than a second. As the days have gone on, the bills page has been getting slower and slower and now takes at least 20 seconds to load. I am just wondering if this is normal or if there is something wrong. Thanks.

It seems, autorefresh is broken when you select device go into ports and select specific graph to view it on full-screen. Actual refresh is working and you can force it by pressing F5 but graph doesn't update until you click again on one of time-window graph.

It seems word "Used" on Cisco memory graph misplaced, it should be above percent value, but currently it above total memory.

light blue peak on graph
by Nikolay Shopik 21 Oct '11

21 Oct '11

So I got one device polled by cacti and observium. And see difference in peaks (outbound as example). What I see is light blue color peaks are bigger than show in cacti but regular blue outline in observium graph match cacti peak. Is light blue peak is interpolation of data, how its caclucated or where it comes from?
