I have the same issue. We are running a bunch of DSLAM (Zhone and Keymile) and we want to monitor the numebr of calls, the temperature and so on (no more than 10 SNMP OID checks). How can I ask to add this kind of support? Can I write my own check files for this hardware and (if it's working fine) pull up on the main release? Where to start writing a custom check? Regards

add specific OID to a host to monitor.graph
by John Brown 02 Jan '15

Hi, I'm working towards building some additional OS and device definitions for Observium. At first, I would like to know if there is a way to add a specific OID to a device to be monitored. Other words, I have a device and the standard mibs are being monitored / graph'd. I'd like to add a specific OID to also be monitored / graphed. thanks

Re: [Observium] Many false positives

I'm following back up to the list, in hopes that others will find this and it will help them. Part of figuring this out was to track server (the host observium is running on) utilization in terms of Disk IO, CPU, Network IO, swaps, etc. In general we had to upgrade our server to handle a higher compute load / cpu load. We had been running Cacti on the same hardware platform with about 3x the devices, polling every 1 minute and no issues. When running Cacti we also used the C based poller environment (spine). Observium requires more CPU. We also increased our SNMP time out value in the config file. This helped mitigate the issue, but at the end of the day, more CPU fixed the issue. Now the SNR (Signal to Noise Ratio) has reduced and alerts / data from Observium is considered reflective of the devices status. Once we stabilize and goto production, I'll post our hardware / os configuration along with other relevant data for others to reference. cheers and thanks to those that provided on-list and off-list usable feedback.

What's with the annoying mail clients which keep sending mails directly to mailing list members *AND* the list causing replies not to go the mailing list? BLEH. adam. ------ Forwarded Message ------ From: "Adam Armstrong" <adama(a)memetic.org> To: "Anthony Polselli" <Anthony(a)naturalnetworks.com> Sent: 12/31/2014 7:38:27 PM Subject: RE: [Observium] Custom SNMP OID Ok, so the solution here is to write a "graph" poller module, add the relevant MIB to the list of supported MIBs for that OS type and write graph definition arrays for the relevant graphs. It's a little more complex if the OS is detected as Linux, since we don't have the ability to selectively add MIBs at the moment, we'd have to add that. The basic design ethos of Observium is that everything should be automatically discovered except where automation is realistically impossible. It's a long standing and quite strict policy which is responsible for basically every difference between Observium and Cacti. If someone can write a Cacti-esque template to graph something they want, why would that not just be added as a poller module? Because it's harder? But one means only 15 people use it, the other means all 10,000 observium users get it. I've long hated the cacti method of doing things, forcing the users to either write support for themselves or find some ancient badly written templates on a forum. This just means that half a dozen people write exactly the same support, and only half of the people who need it get access to it. It's way better to spend twice as much time writing some code which can be included in the release and automatically delivered to everyone. We've a few other internal design policies that people might not be aware of, but they're not so relevant here :) adam.

Hi, On certain wireless links we get "port errors". I'd like to disable these alerts on a device/port basis. Didn't see anything obvious on how to disable those. thanks

Any "how-to" help here would be great.
