Using Obserivum on server with multiple interfaces/vlan?
by Johann Mallet 29 Sep '16

29 Sep '16

Hello, Simple question : We need upgrade our Observium deployment with multiple networks (public & private). Does Observium have any issue accessing nodes via more than one server interface? Whether two different physical ports or two different vlans on the same port? Some proprietary vendor NMS solutions are somehow locked to one interface only and cause great trouble. :o) Thanks, Johann

Bandwidth Reporting Off
by Talk Jesus 28 Sep '16

28 Sep '16

I’ve been using Observium for a while and there seems to be some discrepancies between my graphs and the upstream (my data center provides me Ethernet GigE bandwidth). For example, from around 8am to 12pm today it showed overall utilization pretty consistent well above 400Mbps. These switches are actually trunked (2 x 3650 L3 switches). In the graph, it shows the uplink to switch #2 connectivity calculated with the total utilization (VLAN2155). This is definitely not accurate as it shouldn’t do that as far I’m concerned. Total utilization should simply be Drops #1 & #2, which covers all VLANs on both switches. Example: Drop #1 = 40Mbps Drop #2 = 200Mbps Uplink to Switch #2 = 130Mbps Now as a result VLAN2155 (total utilization) is calculating not only #1 and #2 drops from the upstream, but even the trunk port labeled “Uplink to Switch #2”. I disabled polling on that uplink port and the total utilization (VLAN2155) is still far higher than what the output is for the past 24 hours from the upstream provider. They show 187Mbps past 24 hours (95th), 219M In / 202 Out. I show 266M In / 182M Out. Why is it so drastically different? Why is Observium calculating the “uplink” to the trunked 2nd switch in the total utilization graph? This is throwing off accuracy.

VRF/BGP/OSPF discovery in vrf-lite (nx-os)
by Stef Renders 28 Sep '16

28 Sep '16

Hi Does anyone know whether it is currently possible to discover bgp/ospf routing instances within a VRF on the NX-OS platform ? We migrated from IOS to NX-OS, IOS was passing them through snmp just fine. But NX-OS requires snmpv3 contexts for vrf resources. A full walk in the 'default-vrf' does not contain any metrics for the vrf's running on this VDC. The problem is more or less described here as well: https://github.com/librenms/librenms/issues/280 Kind regards Stef

Port Group / Entity Question
by Pico Leto 28 Sep '16

28 Sep '16

Hi, Can a port group contain multiple entities checks? I'm trying to just group our carriers for each location into port group. For instance I have our isp/carriers listed in the following format for the port descriptions on our routers L3:CKTID:DEMARC COG:CKTID:DEMARC My entity matches on either of those but when I combine them like the following below, I don't see any devices being associated with it. ifAlias matches *COG:* ifAlias matches *L3:*

Can't Hide Search

Upgraded to latest CE version yesterday. Now the layout is different from 15x and the big search box on the left side of the port listing or device listing won't hide. I replicated this 2 browsers as well.

Cisco subinterfaces

Hello Lost the graphs on subinterfaces and portchannels. We rebooted a 7604 with IOS 15.4(3)S2 and monitored with Observium 0.16.9.8104. Somehow the graphs ID-are changed and doesnt belong to the same subinterface/portchannel.

Please review this Cisco document regarding interface persistence. This is likely the issue you are seeing, not a problem with Observium itself. http://www.cisco.com/c/en/us/support/docs/ip/simple-network-management-prot… There is a command you can include in your configuration that will keep interface numbering persistent across reboots. I just don't recall it exactly off the top of my head, or I would include it here. ...

Trunk Issues
by Talk Jesus 28 Sep '16

28 Sep '16

I've been using Observium for a while and there seems to be some discrepancies between my graphs and the upstream (my data center provides me Ethernet GigE bandwidth). For example, from around 8am to 12pm today it showed overall utilization pretty consistent well above 400Mbps. I have two drops from them: primary and secondary (redundant). Plus, they both show active instead of active/passive. Not sure if that has anything to do with it. >From the tech: "95th percentile is calculated from both ingress and egress traffic. For example, if you used a constant 200Mbps up and down, then you would only be charged your commit of 200Mbps, not double. I do see what you mean that the two handoffs (layer 2) are equaling more than 300Mbps, but when you look at the Aggregate (layer 3) graph at the top, it does not go over 300Mbps. These packets can possibly be queued before going out so you don’t go over your commit. " So, what do you think might be causing this hiccup? I noticed this too: so these switches are actually trunked (2 x 3650 L3 switches). In the graph, it also shows the uplink connectivity calculated with the total utilization. This is definitely not accurate as it shouldn't do that. Example: Drop #1 = 40Mbps Drop #2 = 200Mbps Uplink to Switch #2 = 130Mbps Now as a result VLAN2155 (total utilization) is calculating not only #1 and #2 drops from the upstream, but even the trunk port labeled "Uplink to Switch #2". How can I rectify this with Observium to avoid that and get an accurate output?
