Add sensor data to dashboard
by Ivo van Tulden 14 Oct '23

14 Oct '23

Goodmorning, Please be advised that we just got a license, so if this isn't the correct way to get the information, please advice me how to do better. Is there a possibility to add a graph of a device to the dashboard, so the live information of that sensor data is shown? The link to the graph is something like this: https://<servername>/graphs/to=1697179853/id=313/type=sensor_graph/from=1697093453/<https://%3cservername%3e/graphs/to=1697179853/id=313/type=sensor_graph/from=1697093453/> Met vriendelijke groet, Ivo van Tulden Technical Infrastructure Engineer - IT Department << Security is van ons allemaal >> **** DISCLAIMER: The information sent in or attached to this e-mail is for the addressee only.

Obtaining good thresholds for monitoring SFP light levels
by Corwin Ziegler Hunts 11 Oct '23

11 Oct '23

We would like to alert if an SFP's received light level is too low. The light level sensor data is present and linked with a specific port so we can adjust the alert checkers based on attributes of the linked port. What we haven't figured out how to do is get appropriate thresholds for alerting for each SFP. The SFPs define warning and alarm thresholds which are readable on the devices containing the SFPs but that data doesn't make it into Observium for most of our monitored devices as far as we can tell. Similar SFPs usually have similar thresholds so grouping by SFP vendor and part number then creating a check for each set of SFPs with manually extracted and entered thresholds could be acceptable. Observium does show the SFP vendor and part number on the device overview and inventory pages along with which port contains the SFP but there doesn't seem to be a way to reference this data when creating port or sensor groups or alert checkers. There are also the automatically generated or manually set thresholds for sensors inside Observium itself. The automatically generated thresholds are often missing and we are not aware of a way to ensure they are present or reasonable. Manually set thresholds could work if there was a way to set and audit those thresholds in an automated fashion. We don't see a way to use the API to do this though (we're using the subscription edition). Are there recommendations on how to achieve this? Is this a solved problem and we're running into a bug? This is feeling more difficult than it should be. Corwin

device_rebooted metric is now NULL instead of 1
by Corwin Ziegler Hunts 10 Oct '23

10 Oct '23

We have an alert checker using the device_rebooted metric to monitor for reboots. The metric used to read as 1 when a reboot was detected as is documented <https://docs.observium.org/entities/#device>. After updating to the latest stable revision (r13020) from r12520 the metric now reads as NULL immediately after a reboot. Is this change in behavior intended? Corwin

repeated recovery messages
by andregeissler＠posteo.de 09 Oct '23

09 Oct '23

Hi I get new recovery messages for my pandacom devices (pandacom-sc) all the time. Observium does not show any alerts. For a device that has not reported any event at all since October 5, Observium shows hundreds of recoveries today alone. Any tips on how to debug this would be greatly appreciated. Andre

Observium doesn't show interfaces within VPRN on Nokia routers
by Tao Zhang 05 Oct '23

05 Oct '23

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

Hi, we have observium installed and working fine (polling 629 devices). It is currently installed on a physical server. How advisable is it to promote it to a virtual server? -- Saluda cordialmente

CustomOID Draw Error
by amat＠tvfactory.ch 05 Oct '23

05 Oct '23

Good Morning, We're having trouble with observium and "Custom OID" SNMP retrieval. The Huawei (S6730 V200R019C00SPC500) monitors portspeed and other. However, we are trying to get some Custom OID for hwAvgDuty5min refelecting the Average 5 Min CPU usage. (A) SNMP Walk On the same machine that Observium is installed the snmpwalk returns a value that makes sense administrator@m01:/opt/observium/html/weathermap/configs$ snmpwalk -v2c -c community-hidden 151.252.33.12 1.3.6.1.4.1.2011.6.3.4.1.4 SNMPv2-SMI::enterprises.2011.6.3.4.1.4.0.0.0 = INTEGER: 9 (B) Observium - Configure Custom OID Numeric OID 1.3.6.1.4.1.2011.6.3.4.1.4 we also tried Numeric OID 1.3.6.1.4.1.2011.6.3.4.1.4.0.0.0 Text OID hwAvgDuty5min Value Type GAUGE Description Average CPU Usage Display Unit cpu-usage Display Symbol % Kibibyte (1024) no Log Y Axis no Audo-discovery Yes Unfortunately it does return a "Draw Error". If we do open the CustomOID Graph we see Error: Openeing '': No such file or directory. Any idea what goes wrong here? Kind Regards Ramon Amat

Hello, does anyone know if observium can retrieve BGP peering info via SNMP with RouterOS 7.10+? It is now supported on Mikrotiks side, I am able to see the info via snmpwalk with OID 1.3.6.1.2.1.15.3.1 [cid:image003.png@01D9F6A7.A13EF790] [cid:image002.png@01D9F6A7.3CD825B0] Ryan Bergen Network Lead HyLife Ltd 5 Fabas Street, Box 100 La Broquerie, MB R0A 0W0 p 204-424-2300 x472 hylife.com<https://hylife.com/> • Ryan.Bergen(a)Hylife.com<mailto:Ryan.Bergen@Hylife.com> [cid3813500305*image001.png(a)01D93182.760726F0]

Hi Adam, Did you manage to implement this ‘math parser’ feature for custom oid’s?

Devices with multiple IP addresses
by Sanjeev Gupta 01 Oct '23

01 Oct '23

Hi, Thanks Adam, I am back to using Observium after many years (was on the Subscription, now on Community).. I have a question on a router (and some similar devices). The router has two interfaces, both visible from the Observium poller. It has been discovered twice, and appears twice as well on the map. I cannot find a script, or anything in the UI (which I am still exploring) or the FAQ. What should I be looking for? -- Sanjeev Gupta +65 98551208 http://sg.linkedin.com/in/ghane
