Upgrade to NAV 5, navsyncdb barfs
by Ingeborg Hellemo 11 Mai '20

11 Mai '20

I'm in the middle of upgrading NAV from 4.8 to 5.0.5 and running 'navsyncdb' to alter the database schemas. (The database is named nynav because this is a test upgrade) /#navsyncdb Existing namespaces in nynav search path: "$user", public. Adding manage, profiles, logger, arnold, radius. Applying outstanding schema changes sql/changes/sc.04.09.0001.sql: OK sql/changes/sc.04.09.0050.sql: OK sql/changes/sc.04.09.0100.sql: OK sql/changes/sc.04.09.0110.sql: OK sql/changes/sc.04.09.0200.sql: OK sql/changes/sc.05.00.0001.sql: OK sql/changes/sc.05.00.0010.sql: operator is not unique: unknown || integer LINE 29: 'SNMP v' || snmp_version || ' read profile #' || row AS na... ^ HINT: Could not choose a best candidate operator. You might need to add explicit type casts.

have no issue this equipment combination of Cisco and Ubiquiti. Due to an odd issue, did end up dropping the VM and simply created a new one with latest Debian and latest NAV version, re-populating the equipment and configuration. Which may have been why certain things came to light? The Netmap doesn’t appear to be fully populated – suspect that it’s a cascading result of the above error?

Experience with NAV in large networks
by carsten＠strotmann.de 01 Apr '20

01 Apr '20

Hi, I'm evaluating NAV for one of my clients. As I have seen similar systems to NAV breaking down in large (> 100.000 devices) networks, I would like to know if anyone has experience with NAV in such large networks and how NAV scales in these networks. Anyone using NAV in such large environments? Greetings Carsten

website down?
by Steve Kersley 01 Apr '20

01 Apr '20

Morning, I can't imagine that you're not aware, but the NAV website has been down for the last few days. The documentation subsite is up, but the main site not. I'm guessing at the moment there are more pressing issues! Hope all NAV creators and users are well! Steve.

Announcement: NAV 5.0.5 released
by Morten Brekkevold 14 Mar '20

14 Mar '20

It's Friday the 13th and a pandemic is upon us, so we thought: Why not release the fifth maintenance version of the 5.0 series of NAV! The source code is available for download at GitHub [1]. New packages for Debian 9/10 (Stretch/Buster) are available in our APT repository [2] as usual. Please also be extra aware of config file changes. Look out for `*.dpkg-dist` files in /etc/nav and make sure to update your running config. The virtual appliance will be updated shortly. Deprecation warning =================== Python 2 reaches its end-of-life on **January 1, 2020**. NAV 5.0 therefore moves to Python 3, and as such, you will need at least Python 3.5 to run NAV. Most of NAV will still run on Python 2 as of the 5.0 release, but from this point, Python 2 will be deprecated and we will start removing code that exists solely to keep compatibility with Python 2. Changes ======= Fixed GitHub issues in this release: * #1994 (snmptrapd linkupdown plugin does not handle v2 traps) * #2101 ([BUG] Geomap data API endpoint crashes with a TypeError) * #2109 ([BUG] ipdevinfo sensor details page crashes with AttributeError on unit-less sensors) * #2111 ([BUG] Logging non-ASCII characters crashes NAV programs) * #2113 (Document advice for robust e-mail) * #2114 ([BUG] Unable to save status filter in [Status] page) * #2119 ([BUG] Latitude/Longitude is displayed weirdly in the SeedDB room list) * #2123 (Drop support for legacy status preference pickles) * #2129 (Euthanize unresponsive ipdevpoll workers) * #2130 ([BUG] Cannot import dashboard) Please see the release notes [3] for more details. Happy NAVing everyone!

Need to add devices manually?
by Michael Schwartzkopff 24 Feb '20

24 Feb '20

Hi, I am trying nav for the first time. I have a seed device. A LLDP neighbor us detected as "unrecognized neighbor". nav can access the device with SNMP. nav does not add this device automatically. Do I have to add the new device manually? Why does nav not add it automatically?

Trunk links with LACP
by jaumeramos＠iesebre.com 07 Feb '20

07 Feb '20

Hi. First post here, hope it's the right place to ask questions. I'm trying NAV to document my network, it's a state college due to professional trainin with 600+ computers. My network equipment are mostly d- link switches, with mikrotik routers and some Cisco stuff. After enabling SNMP and LLDP i got an approximate map of the network, but the trunk connections using LACP protocol does not show in the map. Is there some additional configuration needed to make NAV detect them. Thanks for such a great piece of software.

by René Romijn 02 Des '19

02 Des '19

Hi, We did an upgrade to a new VM, we installed Debian Buster and we installed NAV 4.9.8. After that we did a restore of the postgress db with navsyncdb, and we also restored the /var/lib/graphite directory to have the history of the graphs. But now if i reboot the new NAV server, the graphs are resetted tot he point we did the restore. In the console log we see this error: 16/09/2019 08:02:28 :: Unhandled Error Traceback (most recent call last): File "/usr/lib/python3/dist-packages/twisted/python/threadpool.py", line 250, in inContext result = inContext.theWork() File "/usr/lib/python3/dist-packages/twisted/python/threadpool.py", line 266, in <lambda> inContext.theWork = lambda: context.call(ctx, func, *args, **kw) File "/usr/lib/python3/dist-packages/twisted/python/context.py", line 122, in callWithContext return self.currentContext().callWithContext(ctx, func, *args, **kw) File "/usr/lib/python3/dist-packages/twisted/python/context.py", line 85, in callWithContext return func(*args,**kw) --- <exception caught here> --- File "/usr/lib/python3/dist-packages/carbon/writer.py", line 189, in writeForever writeCachedDataPoints() File "/usr/lib/python3/dist-packages/carbon/writer.py", line 98, in writeCachedDataPoints (metric, datapoints) = cache.drain_metric() File "/usr/lib/python3/dist-packages/carbon/cache.py", line 187, in drain_metric metric = self.strategy.choose_item() File "/usr/lib/python3/dist-packages/carbon/cache.py", line 116, in choose_item return next(self.queue) builtins.StopIteration: Is this easy to fix?

Downgrade back to 4.9.8?
by Steve Kersley 14 Nov '19

14 Nov '19

Afternoon all, Is there a way to downgrade a Nav install to 4.9.8? Or will I need to blow away the database and start from scratch (no huge deal to be honest). Confession: I'm running it on Ubuntu rather than the recommended Debian. It got upgraded to 5.0.0, but as the Ubuntu LTS releases don't have a version of graphite-web that works with wsgi-python3 it's become an either/or, and I use graphite for storing other metrics as well as those from Nav. On attempting to pin the older version of Nav, it's failing to install because the database update script failed. Which I presume is because it had already upgraded the database for 5.0.0. I'm also toying after this to look at options of having Nav (and graphite and other services on this machine) as Docker containers simply to avoid version clashes in future. I see that Docker is listed as experimental, are there any particular issues to be aware of? Steve.

NAV netmap
by Erik 14 Nov '19

14 Nov '19

Hello, two questions on this part of NAV. 1. I have rooms which are in nested locations like "Address > Town > Country" but when I select "town" nothing shows in Netmap? Only selecting a room will show anything. I would have expected to show all which are below the nested set? 2 Is it possible to have a URL which wiil show a selected View in Full Screen directly so I can show it on a Dashboard monitor without manually having to select Full View? Cheers Erik

Hi, After upgrading from 4.9.8 to 5.0.0 all works fine, except the "neighbors" tab. It worked fine in 4.9.8, but after upgrading it is blank? Cheers Erik

Announcement: NAV 5.0.0 released
by Morten Brekkevold 08 Nov '19

08 Nov '19

The first feature release of the 5.0 series of NAV is now out! The source code is available for download at GitHub [1]. New packages for Debian 9/10 (Stretch/Buster) are available in our APT repository [2] as usual. Please also be extra aware of config file changes. Look out for `*.dpkg-dist` files in /etc/nav and make sure to update your running config. The virtual appliance will be updated shortly. Deprecation warning =================== Python 2 reaches its end-of-life on **January 1, 2020**. NAV 5.0 therefore moves to Python 3, and as such, you will need at least Python 3.5 to run NAV. Most of NAV will still run on Python 2 as of the 5.0 release, but from this point, Python 2 will be deprecated and we will start removing code that exists solely to keep compatibility with Python 2. Changes ======= User-visible features and improvements: * #1793 (Add maintenance filter option to netbox API endpoint) + #1995 (Add maintenance filter to Netbox API endpoint) * #1859 (Improve portadmin support for dot1x) * #1905 (Add support for alcatel DDM-sensors) * #1908 (Add display widget for binary/boolean sensors to "racks") * #1919 (Add support for external sensors from newer Watchdog products) + #1926 (Add support for most external sensors on newer watchdog products) * #1930 (Refactor IT-WATCHDOGS-MIB MibRetriever implementations) * #1943 (Improve support for boolean sensors in racks) * #1947 (Management profiles) * #1969 (Store local chassis ids from LLDP-MIB and use for neighbor lookups) * #1970 (Add API for management profiles) * #1971 (Provide option to automatically enable CDP on voice ports) + #1974 (enabling CDP when a voice port is set using portadmin) * #1987 (Refactor power supply and fan monitoring functionality) * #1988 (Add status monitoring for Juniper PSUs and FANs) * #1989 (Collect optical sensor measurements from Coriant Groove devices) * #1998 (Remove support for alert dispatching over Jabber) * #2002 (Refactor installation documentation.) * #2005 (Export stream of serialized alerts from the event engine) * #2007 (Support REMOTE_USER header for web authentication) * #2008 (Add more database stats to Watchdog's "NAV by the numbers") Fixed GitHub issues in this release: * #1978 (Netmap layer 2 traffic data requests to Graphite are too slow and too large) * #1979 (Location alerts widget crashes intermittently) * #1980 (Using the wrong Radius dictionary file can cause servicemon to eat all available system memory and hang) * #1984 (Blank sysnames should not be allowed) + #1985 (Disallow blank sysnames) * #1990 (Make type changes immediately when unknown types are encountered) * #2004 ([BUG] Interface browser shows wrong "last used" date) * #2009 (Ensure rooms require a location attribute also in the SQL schema) Please see the release notes [3] for more details.

Napalm

Hi, I build a new NAV server based on 4.98 on Debian 10. I would love to have Napalm back under the hood, but can't find a working manual for it? This one does not work (anymore?): https://netbox.readthedocs.io/en/stable/installation/2-netbox/#napalm-autom… Help? Cheers Erik

DNS service check, UDP or TCP?
by Ingeborg Hellemo 24 Okt '19

24 Okt '19

The NAV service monitor lets you monitor DNS. You then get graphs for availability and response time. Does this measure UDP or TCP response time? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Re: copy all data and settings to new NAV install

Hi Erik, This sounds more like a user question than something relevant for the developer's list. Therefore, I'm copying the user's list. This is in the documentation [1]. You may also simply want to use PostgreSQL's `pg_dumpall` program, as mentioned on that page. [1] https://nav.uninett.no/doc/latest/howto/migrate-data.html -- Morten Brekkevold Uninett

Announcement: NAV 4.9.8 released
by Morten Brekkevold 22 Aug '19

22 Aug '19

The eighth maintenance release of the 4.9 series of NAV is now out! The source code is available for download at GitHub [1]. New packages for Debian 9/10 (Stretch/Buster) are available in our APT repository [2] as usual. The Debian packages for NAV 4.9 have been rebuilt using dh-virtualenv, which means that most of the Python dependencies are now embedded into the packages themselves. If you have previously added a priority apt pin for packages from apt.uninett.no, you may now remove it, as there are no longer any other packages needed from that repository to run NAV. Please also be extra aware of config file changes. Look out for `*.dpkg-dist` files in /etc/nav and make sure to update your running config. The virtual appliance is currently being updated at the time of this writing, and will be uploaded soon. Changes ======= Fixed GitHub issues in this release: * #1753 (SNMP-less servers are no longer connected in the NAV topology) * #1941 (Interface information pop-ups in the status widget tends to hang) * #1942 (get_mib() should be able to load MIB modules from outside the nav.smidumps package) * #1962 (Environment rack widget edit mode crashes if there are racks in rooms with non-ascii characters in their name) * #1964 (smsd crashes when discarding non-dispatchable messages with non-ASCII chars (or for users with non-ASCII chars in their name)) * #1972 (Ensure PostgreSQL unique constraints are consistently named) * #1973 (Stop explicitly installing pl/pgSQL during db init.) * #1975 (Unhandled ValueError in eventengine when snmptrapd posts invalid linkState events) * #1976 (Properly display sensor data scale on sensor details page.) * #1977 (Use Juniper 802.1X VLAN workaround in default configuration) Please see the release notes [3] for more details. Happy NAVing everyone!
