I'm left with only two possible options: 1. You are losing UDP packets (as mentioned by the debugging guide) 2. You are in fact experiencing a cache saturation problem with carbon-cache, but it's somehow being masked by its reporting of negative cache numbers. I'd try a newer version of carbon-cache if I were you, to see if that helps. If you are indeed experiencing cache saturation, a non-buggy version might expose it properly and you can take the necessary steps - such as running multiple carbon-caches or storing your Whisper files on an SSD (although I'll add, as I've done before, that we are running carbon-cache 0.9.10 in production, as upgrading to 0.9.12 gave us abysmal performance, with cache saturation on almost every installation - so even downgrading might help). If all else fails, you should contact someone within the Graphite project. See [1] or try #graphite on Freenode. [1] https://graphiteapp.org/ -- Morten Brekkevold UNINETT

How to add "Getting started" widget
by Ingeborg Hellemo 01 Mar '18

01 Mar '18

I seem to have removed the "Getting started with NAV" widget from det default user, and now new users miss the opportunity to take the 30 second tour. How do I add this? I can't find it in the widgets menu. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Is that a healthy carbon cache?
by Karl Gerhard 01 Mar '18

01 Mar '18

Hello, we're having problems with gaps in graphs (only for some interfaces) and I'm working through the https://nav.uninett.no/doc/4.8/faq/graph_gaps.html guide. I've arrived at the part with the "Carbon Cache" and I'd like to know whether those two graphs represent a healthy state: http://abload.de/img/e7zassl.png http://abload.de/img/jyz3sjf.png What strikes me as odd is that there are negative numbers, I can't see that on the graph on https://nav.uninett.no/doc/4.8/faq/graph_gaps.html Best regards Karl

Integrated Documentation Wiki
by cthompson＠egf.mn 27 Feb '18

27 Feb '18

Hello: Is there any efforts to add a "Wiki" or "Documentation" tab to netboxes and rooms? I'm thinking of integrating something like a mini wiki, like TiddlyWiki , in an additional tab for netboxes and rooms to have field editable configuration notes, etc. - maybe with the ability to store files to be associated with the device or room also (manuals, configs, drawings, photos, screencaps, et al). Looking to see if anything similar is being worked on, before I start studying the NAV code and look how to integrate such. Thanks Corey Thompson Technology Manager East Grand Forks Water and Light cthompson(a)egf.mn

Business report - linkDown, erroneous listings
by Ingeborg Hellemo 15 Feb '18

15 Feb '18

The business report for Link Availability are supposed to show links that are expected to be up but are experiencing downtime. Links that have never been up or that are down and the linkDown alert is acknowledged/cleared will not show up here. Have I understood this correctly? We now have a handful of links which have been down "forever", but NAV did at some point last Friday decide that the links were up, ended the linkDown status and shows the links in the business report with nn% downtime. All these links are still down and NAV thinks the link is Inactive. (It is possible that the NAV processes including ipdevpoll was restarted at the point the error was introduced) How can we clean up this mess and remove the links from the business report? --Ingeborg

Missing some uplinks
by cristina.caselles＠grupoversia.com 30 Jan '18

30 Jan '18

We updated our installation to 4.8.3 (Real Topology: some C2960 Cisco connected to a pair of Nexus) NetMap does not work properly (missing some uplinks). We edit IP Device info and, although NAV sees there links as unrecognized and after having added those unrecognized neighbors to NAV. Connections do not appear. Remote Name (as identified by NAV in unrecognized neighbors) is different from Sysname in the Seed Database (obtained from host file). Any suggestions? Is it better not to use host file? Does anyone work with Nexus? Best Regards, Cris

Feedback about the new IP Device Info
by René Romijn 12 Jan '18

12 Jan '18

Hi, We used the old layout in the function IP Device Info a lot in NAV and we are trying to get used with the new layout but here are some comments about it: * With the new layout with switches > 24 ports or 48 ports you have to scroll down to see the active/inactive ports, the old view give you on one page all the ports. * The 'last used' is stated 'Never' for uplinks, this is kinda confusing. * With the old layout you could use with the switch activity tab the history of some amount of days to check activity so you could see very fast wich ports arent used. Now you see the last date (except for the uplinks), but the older view was more easier. Curious about other people's oppinions. Kind Regards, René.
