Incorrect sensor limits caused by duplicate unit conversion
by Corwin Ziegler Hunts 04 Sep '24

04 Sep '24

The definition for the temperature sensor on a CyberPower PDU (or UPS) environmental sensor accessory defines both "unit" and "limit_unit" as "F". This seems to cause the limit values to get converted (to Celsius) twice: first in "entity_limits_definition" using "limit_unit" and then in "discover_sensor_ng" using "sensor_unit" which is set from "unit". For us, the SNMP read limits of 59 and 90 F end up as -9.44 and 0.12 C on the sensor in Observium. This is on version r13629. Simply not setting "limit_unit" is a workaround if both the sensor and limit values use the same unit (maybe that is preferred when defining sensors?). If the units are different a proper fix is needed. Also, is this the preferred method for reporting this kind of issue? Corwin

How to add a device which only responds to ping/icmp?
by Thomas Stather 23 Aug '24

23 Aug '24

Hi How can i add a device which cannot (!) speak any snmp and only responds to ping/icmp requests? We have an Aruba wlan setup (Mobility Master and two Mobility Controllers) and i want to add the aps to Observium, so that they are monitored but only by ping/icmp. (The MM and the two MCs are already added to Observium, but i cannot see if one AP went offline or came back online again) The aps cannot speak any snmp when managed by the MM or MC, thats why it fails when i try to add one via ./add_device.php I appreciate any help :) Best, Thomas -- Thomas Stather IT Services VCP4, VCP6-DCV, VCP6.5-DCV Tel: +49 6221 486 628 Fax: +49 6221 486 561 Bevor Sie diese Mail ausdrucken, prüfen Sie bitte ob dies wirklich nötig ist.

Observium doesn't show interfaces within VPRN on Nokia routers
by Tao Zhang 21 Aug '24

21 Aug '24

Hi Observium team, We are using Observium as a main tool to monitor our router interfaces and collect SNMP stats. We recently replaced our Juniper routers with Nokia SR 7750. We noticed that Observium doesn't work very well with Nokia routers. Observium can only show the interfaces in the master instance, not the interfaces within VPRN or VPLS instances (Nokia call those interfaces SAPs). To be able to see interfaces within VPLS or VPRN, we need to enable two other MIBs, TIMETRA-SAP-MIB and TIMETRA-VRTR-MIB. We are not sure how to enable those two MIBs. Do we need to add them manually? This is the MIBs enabled on the Nokia router (default). [cid:ece89bfc-3ae2-4dcd-9c7c-641c3978f803] Any suggestion is greatly appreciated. Thanks, Tao

Re: How to add a device which only responds to ping/icmp?

Dear, We bought the license to monitor devices via ping-check (with the probe functionality). "Observium is designed to collect and display data from SNMP-capable devices, but not every device supports SNMP. In order to monitor non-SNMP capable devices, the probes system can be used to perform checks on non-SNMP devices". I am just wondering how we can add a device in observium that cannot handle snmp? ________________________________ Als u niet de beoogde ontvanger van deze email bent, lees onze disclaimer<https://www.politie.be/nl/maildisclaimer>.

Observium stops displaying stats for all monitored hosts for a period of time
by Kevin Riahi 21 Aug '24

21 Aug '24

Hello Team, It seems Observium stops displaying stats for all (most) monitored hosts for a period of time and then back to normal.!!! I've attached a few screenshots. Has this behavior been documented in the past? If not what is the best way to debug this. Observium ver 24.8.13606 Running on a dedicated server. 12 Core Xeon Proc 64 GB RAM Raided SSD drives. Thank you Kevin Riahi

Bandwidth alerts based on value in "Device Port Parsed Speed"
by Brad Bendy 14 Aug '24

14 Aug '24

Hi, Checked around and can't figure out a way to do this and don't see anything in mailing list about it. Is there a way to build alerts based on the bandwidth value we are setting this way? For example we have a description of "[600Mbit]" and then want to alert on 80% of this value for example. I don't see a way to do this as the test conditions are all the parameters from SNMP. Obviously can make up a checker and do the math manually and what not but would not auto adjust and I need 100+ of these created. Would anyone else find this helpful? Thanks

Missing some nice stats from Cisco 9800 that I got from Cisco 5520
by andri＠harpa.is 12 Aug '24

12 Aug '24

Hi Our organization recently upgraded from Cisco 5520 WLC to Cisco 9800 WLC. In observium I get really good statistics about wireless client count and wireless ap count on the 5520 but not on the 9800. I am not sure if this is something on observium side or cisco side. But I wanted to ask if anyone has the same issue and if they found a solution. Or maybe this is just something that needs to be added. Please let me know if there is any further information I can submit. Best regards Andri

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
