Bug report: Broken scaling on some SFP receive power graphs
by Corwin Ziegler Hunts 09 Aug '24

09 Aug '24

Hi Observium team, We're having issues with some of the generated graphs. Some of our devices report the light level received by SFPs using mW (rather than dBm). We are on the latest stable revision (13582). Issue 1: The graphs generated by Observium for these sensors usually show an excessive scale of at least -100 mW to 100 mW when the data in the specified time interval are entirely within the range 100 nW to 1 mW and usually only a small chunk of that. The calculated minimum and maximum values shown below the graph are correct. These graphs worked properly in the past with a prior version of Observium. Issue 2: Selecting and deselecting the Force Autoscale option appears to have no effect on the generated graph or displayed rrd graph command. Manually running the generated rrd graph command after removing the "--alt-autoscale" option results in a good graph. Here is the raw SNMP output for one of the these sensors showing a current value of 0.5560mW: ENTITY-SENSOR-MIB::entPhySensorType.1000004631 = INTEGER: watts(6) ENTITY-SENSOR-MIB::entPhySensorScale.1000004631 = INTEGER: milli(8) ENTITY-SENSOR-MIB::entPhySensorPrecision.1000004631 = INTEGER: 4 ENTITY-SENSOR-MIB::entPhySensorValue.1000004631 = INTEGER: 5560 ENTITY-SENSOR-MIB::entPhySensorOperStatus.1000004631 = INTEGER: ok(1) Corwin

Switch overview: configurable interface sorting?
by Wiethoff, Helge 06 Aug '24

06 Aug '24

Hello everyone, The port sorting in the device overview has been changed at some point. Previously, it was sorted alphanumerically, but now the numbers are prioritized. Before, the order was A1, A2, A3..., B1, B2, B3, etc. And now it is A1, B1, A2, B2..., A3, B3, etc. Is there a way to change the sorting back to the old method using a configuration switch? Thank you and best regards Helge

Percent CPU

Hi, cuestion. we have about 600+ devices (switchs, wireless, router), we want know CPU usage on each one . On many devices we see 93% CPU usage. but login into device we can see only 1 measure and shows less than 7% on slot 0.0. While on observium we have 3 measures: processor, processor 1 and slot 0.0. please helpus to get the right measure. example [image: image.png] [image: image.png] [image: image.png] on centos 7 from CLI [image: image.png] -- Saluda cordialmente

Missing rebuild buttons for groups and alert checkers
by Corwin Ziegler Hunts 05 Aug '24

05 Aug '24

Hi, We use Observium groups extensively, often nested several times. Our alert checkers then reference these groups. After making changes to a group, including by adding a device, we used to force rebuilds of the groups (possibly several times) and checkers so the changes would propagate all the way through. We are on the latest stable revision (r13582) and the rebuild buttons are no longer available in the UI (possibly removed in r13391). What should we do now when we need to forcibly propagate changes?

Oxidized Integration?
by Wiethoff, Helge 05 Aug '24

05 Aug '24

Hi, I am currently testing a replacement for rancid. Rancid has worked for a long time, but adding new device classes feels more and more unwieldy. Oxidized [1] makes a good first impression and I was able to add new device classes without big problems. Then of course I would also like to see an integration with my favorite network management tool :-) There are people who have already worked on this: https://github.com/colin-stubbs/observium-oxidized It looks like this patch doesn't quite work for current observium versions, so I'd like to ask if anyone is working on it and what are the chances that there could be an Observium integration (professional edition)? Thanks Helge [1] https://github.com/ytti/oxidized

Polling - Real time port graphs are different on devices that run Linux natively
by ruben.aninoiu＠zananet.com 01 Aug '24

01 Aug '24

Hi Guys, I have noticed that the real-time graphs for devices that run Linux natively (JunosOS, UnifiOS, etc) display the traffic with "intervals in between". The non-native Linux devices (FortiOS, Cisco IOS) provide a nicer real-time graph for port traffic when polled. Is there something that could be adjusted so that the native Linux devices show the nicer graph? Best regards, Ruben
