Authentication level to hide device configs?
by Ryan, Spencer 26 Feb '15

26 Feb '15

Hi Adam (and the other devs) We have a few upper level helpdesk users that I gave global read access to (7) via LDAP groups. However we also have RANCID integration enabled, and I'd really like it if there were a way to disable those users from being able to see the configs. Maybe another security level? 7 - Global read no configs, 8 - Global read with configs? I assume this wouldn't be a trivial change, but if you could stuff it into the "feature request" pile I'd really appreciate it. *Spencer Ryan* | Senior Systems Administrator | sryan(a)arbor.net *Arbor Networks* +1.734.794.5033 (d) | +1.734.846.2053 (m) www.arbornetworks.com

Split of state sensors into separate 'status' entity
by Adam Armstrong 25 Feb '15

25 Feb '15

Hi All, I've just committed code to split 'state' sensors into a 'status' entity to make it easier to alert on these, and to allow us more flexibility with alerting on arbitrary and complex things in future. It's trivial to alert on these, since part of the intention is to allow people to write complex alerting code in PHP which will present ok/alert/warn to observium. http://alpha.memetic.org/~adama/snaps/Observium____-_Opera_2015-02-25_23.30… State sensors will be automatically migrated to status entities, so you just need to make an alert checker. adam.

Email notification for particular alerts
by Arya, Renuka [BSD] - MED 25 Feb '15

25 Feb '15

Hi team, We are working on setting up the alerts using alert checker. I was wondering if there is a way we can send certain alerts to certain users via email/text? I couldn't find anything out.

Alert Checker on Observium
by Arya, Renuka [BSD] - MED 25 Feb '15

25 Feb '15

Hi All, I am just starting to use alert checker in Observium. I started with a basic alert checker on one of my switches but not sure if it is working. See attachment. I wanted Observium to set an alerts if the traffic on any of the ports exceeds 50%. I ran a network performance tool on one of my machine (sending traffic at 8-9 Gbps) but I don't see any alerts been generated. Thanks!

HIgh CPU usage caused by snmp process
by Arya, Renuka [BSD] - MED 25 Feb '15

25 Feb '15

Hi All, Couple of our Force 10 (S4810) Switches are reporting high CPU usage which seems to be caused by snmp processes. This is impacting the network performance. Do we know the MIBS (modules) that cause high load? And how can we disable these MIBs. Thanks!

Change alert checkers/method to make alerts more flexible?
by Hogan Whittall 25 Feb '15

25 Feb '15

Me again. :) I love Observium, but the alerts are a bit of a pain point for me. Admittedly I don't have full, in-depth knowledge of the alerting mechanism but I was wondering why the check conditions and entities are separate. If it were possible (without completely rewriting the whole alert code) to have the entities be a part of the check conditions then that would, by design, allow us to set multiple check conditions on different entities within the same checker. See attached, I realize this doesn't work but this might help explain what I'm wanting. Since there's no entity for active used memory it's very hard to create actionable alerts for high memory utilization until it's too late and the host(s) start to swap. If the check conditions had metric, condition, value, and entity together then I could create such an alert by checking for physical memory used >= 95% *and* cached memory <= 10% (and... if so desired). On the other hand, if the metrics included the entity then there would be no need to have the entities at all? mempool_physical_perc, mempool_cached_perc, etc. I have high hopes for Observium and I'm trying to do what I can to tweak it to do what we need, but my PHP experience is limited. If I can manage to find a resource internally here at work to help out then hopefully we can contribute something back to the community if it's deemed worthy. Just some thoughts. Thanks for all the time and effort being put into Observium! -Hogan

Re: [Observium] Graph / No Auth issue

Hi, Are you sure you didnt update Observium while doing this? As it looks like you ran into a short lived bug that was already fixed...
