How to speed up Geomap?
by Ingeborg Hellemo 04 Des '14

04 Des '14

The transition from NAV 3.15 to 4.X has made Geomap incredibly slow. If I change zoom-level it takes several (four) minutes before new dots and lines show up. I guess this has to do with graphite's webserver not being able to deliver data fast enough (5000 lines of "POST /render/ HTTP/1.1" 200 XXX "-" "Python-urllib/2.7" in httpd-access.log) . The httpd process runs at 100% WCPU Is there something I can tune to make Geomap usable again? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Announcement: NAV 4.2.1 released
by Morten Brekkevold 28 Nov '14

28 Nov '14

The first maintenance release of the NAV 4.2 series is now available. The source code is available for download at Launchpad [1]. A new package for Debian Wheezy has been published in our APT repository [2], as usual. Changes ======= The following reported issues have been fixed: * LP#1395710 (api token can not be refreshed from the api) * LP#1396514 (Status tool in NAV 4.2 shows no events if API call returns a 500 error) * LP#1396516 (Status API in NAV 4.2 crashes when there are old deviant alerts present) * LP#1396517 (Status tool makes hyperlinks out of alert subjects that have no defined URL) * LP#1396531 (logengine spams the error message "KeyError: 'LINK'") * LP#1396914 (netmap filter on location excludes links) In the NAV 4.2.0 release announcement and changelog, four bugfixes were omitted by accident, because they had originally been committed to the 4.1.x release branch. The changelog has been updated. These were the bugfixes in question: * LP#1385121 ("Add graph to dashboard" does nothing under certain Apache configurations) * LP#1386716 (Maintenance task with no end time displays incorrectly in edit form) * LP#1389121 (when searching for an ip-address with space in it, NAV crashes) * LP#1389145 (Netbiostracker crash on unparseable MAC Address) Please refer to the release notes [3] for further information on upgrading. Happy NAVing everyone!

NAV 4.2 empty status page
by Ingeborg Hellemo 27 Nov '14

27 Nov '14

We have just moved our NAV 4.2-box from test to production and with real use the bugs start popping up. One user will not see any Events on his status page, even though he has chosen all possible Event types. The user is even "NAV administrator" How to debug this? We know there are events to be seen and the handful of other users I have tested as will see events as expected. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Additional SNMP Polling through NAV
by jch＠raytheon.com 14 Nov '14

14 Nov '14

I am really new to NAV, but I've liked it so far in my lab testing. I do have some routers whose CPU utilization is not showing up, and I would like to poll some non-standard OIDs (like IP SLA metrics) even if NAV won't display them. I could use graphite to do that for me separately, but utilize the engine that NAV provides. Could someone point me to where I might need to go to do that? Is there an OID somewhere that could be added or updated to support newer router CPU metrics, so that my Cisco ISR-G2 routers will have that displayed? How can I customize the polling of some devices (mostly Cisco routers) to get additional metrics? I have not found where I can modify or add scripts to do this and need some general pointers on where to look on the internet as well as on the system. Since this is just a lab environment, I have all the NAV components on one server. Thanks, Joel

SNMP agent down
by Steve Kersley 13 Okt '14

13 Okt '14

I'm trying out the NAV virtual appliance (4.1.0), talking to 25 or so Cisco switches. It was working fine but after a few weeks, one of the switches is showing a problem, "SNMP agent down". The SNMP agent is not down. The switch is fine, its configuration hasn't changed. I can talk SNMP to it fine using the same credentials from other machines, and the NAV VM can talk SNMP fine to all of the other switches - all have the same SNMP credentials, and most are the same model of Cisco switch. (I was going to test from the NAV VM or watch the network traffic but the appliance doesn't come with the snmp tools or tcpdump, and is isolated from the Internet so not easily able to install them) Restarting the switch made no difference. I've had a rummage in the logs without seeing anything obvious. Any clues where to look to find why NAV is unable to talk SNMP to this one switch suddenly, after working fine for several weeks? Steve.

Unmanaged switches
by pentium100＠gmail.com 13 Okt '14

13 Okt '14

Hello, Is there a way to insert an unmanaged switch to the network map? I use some of them in my network and would like to mark them on the map. Right now I have real network topology something like this: Router -- managed switch -- unmanaged switch -- devices Only one devices on the unmanaged switch is shown, even though multiple MACs are detected on the relevant port of the managed switch. Is there a way to mark that there is an unmanaged switch so that those devices are drawn on the map (with link speed/usage pulled from the devices if possible)?

Mobile routers in NAV
by Sigurd Mytting 26 Sep '14

26 Sep '14

Hi! I will be deploying about 100 mobile routers in cars the next six months, they will be offline whenever the car is moving and out of cellular coverage and when the car is not in use by our roadside people. These routers will be in a closed VPN/APN from our teleprovider so I have full access and controll whenever they are online. I'm wondering how to add these to NAV; I really don't care if they are down and preferably they should not show up as such under "Status". I would like statistics whenever they are online (not to mention the mac-adresses connected, possibly also a few other more specialized metrics like cell signal and so on). If it matters; we'll be using Cisco hardened 819 routers with an integrated WiFi access point. Anyone having any pointers to how I should manage them in NAV? Cheers, -Sigurd
