Issues with IP SLA
by Cartas, Mauro S. 08 Apr '20

08 Apr '20

Hello experts, Need some help to understand how observium handles IPSLA probes links. We have a fully working weathermap with IP sla information (jitter, echo, etc) all nice with nodes and links. Links are configured this way: LINK A-B INFOURL /graphs/type=sla_jitter/id=10495/ OVERLIBGRAPH /graph.php?height=100&width=512&id=10495&type=sla_jitter&legend=no INBWFORMAT {link:this:bandwidth_in:%0} OUTBWFORMAT {link:this:bandwidth_out:%d} BWLABELPOS 50 50 TARGET gauge:../../rrd/router_A/sla_jitter-cisco-rttmon-mib-1100020-LMR_IO.rrd:rtt:rtt NODES Chicago Washington BANDWIDTH 34 Now the problem that we have is that when observium server loses connectivity with router_A (i.e. network outage, check below) It will generate a new ID for the link to the graphic hence we have to go to the editor and update INFOURL and OVERLIBGRAPH ID values. As shown below the ID is 12961 for SLA 1100020 whereas above the ID configured was 10495. [cid:image002.jpg@01D6075C.16B03280] [cid:image006.jpg@01D6075C.16B03280] This becomes very annoying as we cannot maintain a fully working IPSLA map and we're not sure why it's constantly generating new ids. [cid:image007.jpg@01D6075C.16B03280] Hope there is a way to force this ID not to change and remain static no matter what happens as the device ID never changes.

Traffic Comparison widget wrong after moving interfaces between routers
by Darrell Budic 03 Apr '20

03 Apr '20

Folk, I recently added some new routers and then moved interfaces from the old to the new. The transit and peering graphs picked up the new interfaces just fine, but the Traffic Comparison widget on the front page hasn’t. Any ideas on getting it to update? Observium pro 20.3.10324 (stable). I’ve tried deleting and re-adding the widget, and it’s had a discovery run since the change. Thanks, -Darrell

Alerting switch stack status
by Eric W. Bates 02 Apr '20

02 Apr '20

I want to alert whenever one switch in a stack drops out. And I need help composing a checker. Specifically, I have stacks of cisco 2960-X switches linked via flex stack modules such that they appear as a single switch for purposes of ping'ing or snmp. On occasion, one switch in the stack will fail, but the rest of the stack stays on-line and continues to respond to pings, etc. I believe I want to watch the Status entity: Stack is redundant CISCO-STACKWISE-MIB::cswRingRedundant.0 https://mibs.observium.org/mib/CISCO-STACKWISE-MIB/#cswRingRedundant Each stacking module has two cables and one runs cables such that all the switches are in a big loop. cswRingRedundant is a boolean that indicates that such a loop is intact. So it will be False if a switch dies or simply if a cable is unplugged (also a desirable alert). If the switch is a standalone with no stacking modules installed, you get: "No Such Object available on this agent at this OID" I've created a Status entry: <?xml version="1.0"?> <templates> <template type="alert" description="Autogenerated observium template" version="0.91" created="Wed, 01 Apr 2020 11:51:32 -0400" observium="20.2.10302" id="fbe29724e648671f6e2095e9425d7515"> <entity_type>status</entity_type> <name>2960_stack_loop_redundancy</name> <message>Stack loop redundancy has failed (might be a missing stack switch)</message> <severity>crit</severity> <suppress_recovery>0</suppress_recovery> <delay>0</delay> <conditions_and>1</conditions_and> <conditions>status_name == Stack is redundant</conditions> <conditions>status_event == warn</conditions> <conditions_complex>status_name == Stack is redundant AND status_event == warn</conditions_complex> </template> </templates> It doesn't appear to be working (I have one switch with a cable unplugged it should alert on). Do I just have to wait 5 minutes? Or does it read the status from the database? Is that the correct "status_name?" I copied it from the Health --> Status page "Description" column. Should it be quoted? The export XML doesn't include the associations, but I included: device.hardware regexp /.*WS-C2960X-.*/ I don't really know what the value of "device.hardware" might be, but I'm assuming it's the same as the field labeled "Vendor/Hardware" shown on the front page for a given switch? Thanks for your time. -- Clark 159a, MS 46 508/289-3112 -- Clark 159a, MS 46 508/289-3112

Port group and aggregated graphs
by Daniel Johansson 01 Apr '20

01 Apr '20

Hi I added a port group to be able to have an aggregated graph but the graph does not seems to aggregate the ports usage in one graph. See the attached pictures as reference. Site1 have 137Mbit in and 160Mbit out and a spike at over 200Mbit Site2 have 38Mbit in and 80 out and a spike at over 140Mbit The aggregated graph does not show much more than a bit over 100Mbit both in and out in total and with the spike it should show around 340Mbit What has caused this irregularity to happen and should it be like this? ---- Regards Daniel

Aggregate Graphs of Application Data??
by Altheide, Richard 01 Apr '20

01 Apr '20

Does Observium have a capability to present aggregate graphs of data collected from applications like it has for port data? For example, I would like an aggregate graph of my OpenVPN connections from multiple servers. Richard Altheide Network Engineer, Missouri University of Science and Technology

Query Regarding professional licence renewal
by Mohammed Kokani 31 Mar '20

31 Mar '20

Dear Experts, Need some clarification on licence renewal. We had auto-renewal for professional licence, but save card for payment was expired and we updated new card details for renewal, unfortunately our finance team purchased new licence it seems, can we cancel the new purchase and renew the old licence. Your response is highly appreciated. *Thanks & Regards* *Mohammed Suhail | System Engineer* *Tel : +1-888-853-7733* PGP Fingerprint : 026B 6CEB CC08 152D 9372 0F51 DDFB 6758 6924 FBCC [image: cid:image016.png@01D321AA.4A00A6F0]

Re: [Observium] Dynamic Network Map
by Chris Wopat 28 Mar '20

28 Mar '20

This does exist, go to <your_url>/map.php Its use varies greatly on the number of devices you have. It uses `dot` from `graphviz` which you must have installed and configured in config.php ($config['dot']) Also each port shows LLDP neighbors if you go to /neighbors/, and there should be a sub-tab of an interface called 'Map' to show you 1 level of connections. Also, please share your php7 changes for weathermap to that project, we did similar a few years ago but Im not sure if they actually got committed. > > From: Richard Wigzell [mailto:richard.wigzell@it.ox.ac.uk] > Sent: Friday, March 27, 2020 10:21 AM > To: Methe, Mike <mmethe(a)brattlebororetreat.org>; 'Observium' <observium(a)observium.org> > Subject: RE: Dynamic Network Map > > Yes, we already make extensive use of the php-weathermap plugin with some code modifications to better support php7. > > What we are looking for is something that will dynamically draw a network relationship map using XDP data, with the ability to limit the scope to a defined set of devices. > > Weathermap is good for showing network utilization of infrastructure networks (well understood, defined use and good documentation) but not so useful for our ad-hoc or campus stuff (so yeah we don't know what this switch in this cupboard is for but if it goes off this breaks etc). >

Dynamic Network Map
by Richard Wigzell 27 Mar '20

27 Mar '20

Hello, This is a feature we would find very useful, a dynamic network map that can be confined to a defined group of switches (e.g. from LibreNMS https://docs.librenms.org/Extensions/Network-Map/ ). Is this something Observium can already do? Or something that could be added? We are currently using Observium Enterprise (20.2.10291) and have zero interest in also running LibreNMS (or anything else) but this is feature we would really appreciate. The use case we are trying to address is the new on boarding of campus networks previously run by local IT that now fall under our remit (often with little or very poor or just wrong documentation).
