Alert Checks - color coding
by David Roush 04 Feb '15

04 Feb '15

Hello, I was just wondering if someone could explain the grey field in the "entities" column on the Alert Checks page. Are these entities that match the alert check filters and simply aren't polled for whatever reason? For example: [cid:image001.png@01D04055.D8744240] What is the "138" number representing in this case? Thanks, Dave

Didn't think of that [yet]. We should store or check that somewhere so we can alert people on it using the alert thing in the bottom bar.

Either there's a bug, or perhaps you disabled/ignored some ports in Observium? In that case, the poller won't send metrics to the alerter.

Hi all, in my Observium the storage usage of an hardware or software RAID 5 (megaraid or mdadm) device is shown as for example -5277% free at hosts overview page. df -h shows the correct 16% used. Any ideas how to correct this? Regards, Cyrill

Only reason I ask this is because we have had a few devices today go on and off alot and there are no entries in the Event Log Panel of them going off and on but yet ive been getting the email alerts?

An interesting issue with Cisco 2960Cs...
by Richard Kuhns 03 Feb '15

03 Feb '15

Hi all, This is just on the order of a 'watch out' notice. We're currently on 0.15.1.6206, but had the same issue with earlier versions and with the CE. We have 5 Cisco 2960Cs that we monitor, and all were taking horrible amounts of time to poll. Always at least 200 seconds, and often over 300. After some experiment, we discovered that they apparently don't care to talk about CEF (Cisco Express Forwarding). If Observium asks them about it, the CPU usage climbs above 60% and stays there for quite a while. If I go to the device --> edit --> Modules and disable cicso-cef, everything is fine. The CPU drops under 5%, and the poll time is 5 seconds or less. I'm pretty sure we're not losing any useful info, since I don't believe the 2960Cs support CEF in the first place. As I said, this is just a heads up. Observium is a great tool.

Per-user timezone settings
by Steve Costaras 02 Feb '15

02 Feb '15

Been playing w/ observium CE 14.11.6000. We have people in several timezones, currently I have the observium system configured itself for UTC, but it would be better if there was a way to have each user account have their own 'local' timezone setting so that the graphs would show up in their local timezone. Is there any way to accomplish this? Thanks, Steve

OT: GMail (WAS: RE: Not Receiving Alerts ??)
by Phillip Baker 02 Feb '15

02 Feb '15

Off topic rant: In case this wasn’t already obvious from this symptom, nobody should use Gmail for anything important. Some of our customers (one a google apps “partner” or whatever) have seen it silently drop mails including invoice mails etc (despite aligned SPF, DKIM, DMARC, reverse dns, and no current reputational issue). Even if anything is wrong with the message, they shouldn’t be silently dropping mail on the floor. It’s unbelievably broken as a model for handling “spam” which is what I presume they think they’re doing. It’s just about adequate for a personal searchable mailing list archive. That’s about it.

Speed up graph rendering
by Louis Bailleul 02 Feb '15

02 Feb '15

Hi, I am currently using Observium on 149 switches with a total of 10173 ports. I can't say that anything is wrong with it, but the web interface seems a bit slow especially when you want to display pages with a lot of graphs. Observium is currently running in a VM with 4 xeon E5-2650 cores and 3Gb of ram. It's virtual disks are on a local raid5 composed of 10K SAS disks. Observium report that it's VM use on average 25% of its CPUs with spikes at 40% when the web interface is heavily used. The disk I/O doesn't go past 150 ops OUT and rare spikes at 50 IN. Anyone could advise on what kind of hardware or software tweaking could help speed up the thing ? Are they special requirements/tunnings for the rrd storage or the mysql database ? Best regards, Louis
