Hey Team, I am keen to reduce the information that is sent from Observium via the email alerts. Is there any information available on how to tune the alert emails? Thanks!! Bo

High CPU load on Cisco S500G Small business switches
by Jamie Tynan 29 Sep '16

29 Sep '16

Hi, We've noticed an issue with Cisco SG500 switches and Observium, where if you enable stacking mode (the default on the switch), regardless of if it is in a stack or not, the CPU reports a 50% average. Our investigations show it runs at 95% + for a couple of minutes whilst Observium is polling it, then drops back down to <10% when the query finishes. Turning stacking mode off drops the average CPU to <10% and CPU does not ramp up and down. We raised a case with Cisco TAC, who said this is "expected behaviour": >>> At every 5 min cycle, the CPU rises to 85- 95% temporarily and then drops down. The reason for this is, Observium is checking for interface status. When switch is in standalone mode the interface count database is the max switch capacity. Example 48 ports = 48 ports plus channel ports ~ 60 ports In stack mode the predefined port count in the data base is around 880 ports. While the switch is responding to SNMP get , it is using up resources and that is why the CPU utilization will be high. While I was testing it, I did not see or encountered any network outage or Web access issues. We have already made an enhancement request for this behaviour, to limit the port count to any stack configuration. >>> Has anyone else encountered anything similar? Adam - I realise that Observium is only polling what the switch is reporting, but if Observium can ascertain how many switches are in the stack, would it be possible to limit polling to only query active/connected stack members? Thanks, Jamie

Alcatel Lucent : Strange "Interface changed: [ifConnectorPresent]" flood
by Johann Mallet 29 Sep '16

Hello, I have many Alcatel Lucent routers in my backbone. Since I have add these routers, my eventlog is flooded by "Interface changed: [ifConnectorPresent]": http://img15.hostingpics.net/pics/712223floodalcatel.png I have 1274 eventlog pages for the router in example :-/ Do you have the same problem? Thanks, Johann

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
by Talk Jesus 28 Sep '16

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.
