SNMPv3 support
by Matthew Seymour 26 Okt '16

26 Okt '16

Hello. A fellow UK university colleague recommended NAV, and having just taken a look I've fallen at the first hurdle of SNMPv3 support. I've noticed some references to this being in worked on, is there a rough timescale for when this might be available in a release or for beta testing? Regards -- Matthew Seymour Network Technician University of York

How to configure alertmsg
by Ingeborg Hellemo 06 Okt '16

06 Okt '16

Templates for email/sms-alerts are found in ../etc/alertmsg. Where can I find an overview over which variables are available for me to use in messages? The case I am trying to solve is to include organization in some alerts. --Ingeborg

Additional equipment OID addition.

Hi, I'm working on a project to replace all polled data collections we have running on Cacti for our network devices ( Cisco, F5, Brocade, Sanbox, ..... ) to graphite. Actually your tools is the only one using graphite out of the box and I was wondering how much work it would be to add unsupported monitoring MIBs and if there would be some example other than https://nav.uninett.no/doc/4.2/hacking/adding-environment-probe-support.html ? Actually all exotic devices are showing values for their network interfaces but most are not retrieving CPU/Memory and other specific data. Thanks Marc TRANI

Problem: NAV alerts not working
by Patricio, Oscar (Coriant - PT/Lisbon) 22 Sep '16

Hi all, I've been trying NAV out for the third time now, as I am experimenting with several similar tools. First of all, I really like NAV and it is the tool that shows the most potential from all I tried, in terms of network monitoring. BUT (there is always a but in theses emails), I am having trouble getting thresholds and their respective alerts to work. I have really kept my installation to the simples possible, so at the moment I only have one device and I have only setup one single threshold, purposefully so that it immediately is exceeded. But after I do that, there is no event and it is as though the threshold has not been exceeded. When I look into the thresholdmon.log this is what I see repeatedly: 2016-09-21 14:40:01,992 [INFO nav.thresholdmon] evaluating 1 rules 2016-09-21 14:40:02,513 [WARNING nav.thresholdmon] did not find any matching values for rule u'nav.devices.XXXXXXXXX.ports.Bridge-Aggregation1.ifInOctets' <50% 2016-09-21 14:40:02,513 [INFO nav.thresholdmon] done What does this mean? This interface has traffic and that traffic is beeing graphed without issues... So my question is: what am I missing? This is supposed to be very simple to configure but apparently does not work. Am I doing some basic error? Thank you for your attention. Best regards, Óscar

The `-f` switch is to run ipdevpoll in the foreground instead of the background. You will still need to add the `-s` switch if you want output to your terminal and not just to the log file. You can manipulate log levels of various parts of NAV using the `logging.conf` configuration file. There are some examples of level configuration in that file already, but you can add `nav.ipdevpoll = DEBUG` to debug-log everything ipdevpoll-related (which can be quite a lot of output). -- mvh Morten Brekkevold UNINETT

Netmap question
by etiennel＠cos.flag.org 12 Sep '16

Hello, Very nice piece of software - most useful network monitoring tool I have seen in the open-source world. I have a question on the Netmap tool - I'm trying to have external links show and I wasn't able to. The scenarios are: - Edge router connected to the ISP. I can't add the ISP as a netbox as I don't have SNMP query access. So I added it as a server. How can I show on Netmap the edge router, the ISP end-device with a link between the two so I can see the bandwidth utilization and status? - A similar scenario, but with VPNs. I have a VPN router with multiple Tunnel interfaces (Csico) establishing a VPN with remote offices. I don't have SNMP of the remote offices' routers. How can I show this in Netmap tool - showing my VPN router with links to remove devices. I was able to do a similar thing with computers plugged into my switches, but in this case, I guess NAV uses the MAC address to match the device (in this case environment monitoring) with the switch port. Thank you. Etienne

ipdevpolld down
by Zhi-Wei Lu 12 Sep '16

Hi all, We are test driving NAV. I just have nav-4.5.3 installed on our CentOS7 test box. I can now log into the web console and start to add devices. But when I launch the daemon, the ipdevpolld will never stay up, I just wonder I can debug this problem, ipdevpoll does not have any information about why ipdevpolld won't stay up. Thank you very much for your help. Zhi-Wei Lu IET-CR-Network Operations Center University of California, Davis (530) 752-0155

Weird LLDP discovery

Hello, I'm using nav in a "simple" lab environment. I have a firewall (Juniper SRX3400) acting as GW/Router between Vlans that are distributed in some rooms thanks to switches (Cisco and Juniper). In particuler I have a direct fiber link between a Cisco 4948 (named 4948-Datacenter) and a Juniper QFX3500 (named QFX3500-DC). Port of Cisco is Te1/49 and port of QFX is xe-0/0/43 On the map and on the report, I see this on Direct neighborship candidates for 4948-datacenter: Sysname Interface source Candidate neighbor Candidate neighbor port control 4948-datacenter.sdn.lab Te1/49 lldp 3750-core.sdn.lab Gi1/0/24 4948-datacenter.sdn.lab Te1/50 lldp qfx3500-dc.sdn.lab xe-0/0/43.0 I see also this for qfx3500-dc: qfx3500-dc.sdn.lab xe-0/0/43.0 lldp 4948-datacenter.sdn.lab Te1/49 and this: 3750-core.sdn.lab lldp 4948-datacenter.sdn.lab Gi1/45 3750-core.sdn.lab lldp 4948-datacenter.sdn.lab Gi1/46 3750-core.sdn.lab lldp 4948-datacenter.sdn.lab Gi1/47 3750-core.sdn.lab lldp 4948-datacenter.sdn.lab Gi1/48 3750-core.sdn.lab Gi1/0/25 lldp 3750-ucs.sdn.lab Gi1/0/25 On the devices, I have not that (see end of messages).
