Analyze gaps in Port metrics
by René Romijn 20 Apr '21

20 Apr '21

Hi, What is the best way to analyze gaps in the graphs in the port metrics? Since a couple of weeks we have at random some gaps in the graphs. It doesn't look like network errors, because it also happens on some core routers where we have no problems with it at all. Kind regards, René.

Is it possible to put an interface on maintenance?
by Ingeborg Hellemo 02 Feb '21

02 Feb '21

One of my users is doing work on a netbox and links are down. He clicks on the link in /status, ends up on /ipdevinfo/<boxname>/interface=nnnnnnn, chicks Recent Alerts and observes an Unresolved linkState event. He then clicks on the Message and endds up in /search/event/nnnn "Event details" Under Available actions he chooses "Put on maintenance". Is this supposed to work for interfaces? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

ipdevinfo shows empty Function-field for some hosts
by Ingeborg Hellemo 16 Des '20

16 Des '20

NAV 5.1.1 I have so far discovered two devices where /ipdevinfo shows "Function N/A", but "Edit IP device" (and database queries) shows that data is present. The only "special" character is hyphen, but other devices with hyphen in the Function string displays them correctly. I have also tried to change the Function string, but still displays as N/A How to debug? It also seems like it is impossible to empty the Function field (both on these two devices and others I have tried.) If you delete what's written and clicks Save the text reappears. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

The Links widget shows links from the file webfront/nav-links.conf How are these links ordered in the widget? They are neither shown on the order they appear in the config file nor alphabetically. --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø
