Single box scalability/sizing?
by Steve Costaras 04 Feb '16

04 Feb '16

We currently have ~500 devices/50,000 ports being monitored on a dual cpu E5-2643 v0 system. It's currently running around 80% cpu (all cores w/ hyper-threading) and on a raid-10 16 drive array (sas 2.5" 10K rpm) which averages 1k iops. Most systems are polled in < 5minutes (with about 5-10 taking longer as they're fully loaded boxes). Looking to plan for future growth, I'm trying to see if anyone is running larger installations and their performance on a single box in trying to gauge if it's worthwhile to spend the $$ to upgrade to a newer V3 cpu system, or if we've effectively reached a single-point saturation limit and have to deploy distributed. I.e. do we have anyone here running say 1500 devices or 150,000 - 200,000 ports on a single system? If so, care to share your specs? Thanks. Steve

Re: [Observium] Images in alerts

Combining multiple custom OIDs into one graph.
by T-MONT Administrator 04 Feb '16

04 Feb '16

Hi guys, I have a question regarding custom OIDs feature: current approach is to have an OID and combine its values pulled from multiple hosts into one graph. Is (or will be) opposite approach possible - to combine multiple OIDs values pulled from the same host into one graph? Thanks! Regards, Pawel

Set fixed scale of Y-axis on mini-graphs?
by Henrik Cednert (Filmlance) 04 Feb '16

04 Feb '16

Hello I'd like to set fixed values of the Y axis on the minigraphs. Is that possible? I don't find much value of the adaptive scaling since it means I have to read the AXIS and not only throw a quick eye at it to see anomalies. Cheers and thans -- Henrik Cednert cto | td | compositor Filmlance International Direct + 46 (0)704 71 89 54

f5 BIG-IP Alarm
by Anders Johansson 03 Feb '16

03 Feb '16

Gents, I’m trying to trigger an event based upon availability in the ”load balancer” section, trying to find a variable in the device data that I can trigger on. Basically I want to trigger if a Virtual Server is down, or if the HA status change. All that is visible in the GUI but not sure if I can create a trigger for it in the Alarm section, possible? //Anders

Feature or bug -- 0.16.1.7533 version - naming of connected port of known device reverts to Mac address.
by Dirk-Willem van Gulik 03 Feb '16

03 Feb '16

In below devices/port display - we get for Slot0/21 the connected “port” on “device”. - i.e. eth0 on Ypenburg. However for Slot0/24 we get ’10’ on <macaddress>. Even though that actual port is called ‘Slot0/10’ on ‘Fooburg’ and known to Observium. Not sure if this is intentional - or the side effect from some LLCP discovery process gone awry. Dw.
