Problem retrieving port statistics
by Martin.Jaburek＠cah.cz 10 Apr '14

10 Apr '14

Hi, After recreating whisper databases I can see some of the graphs. Now I have another problém - not all statistics are collected! I checked graphite and it displays only few of them. The nav systém have ran for a day now, so I would expect, that it is enough time to collect all informations. In the screenshot (made from graphite webinterface) you can see various collected statistics - they are not even the same for various ports. There are no problems reported for this device in the ipdevpoll.log Any ideas?

We think this may be related to this bug: https://bugs.launchpad.net/nav/+bug/1292513 . This has been fixed and will be part of the next release. The port statistics are probably being stored using the IP-address not the DNS name of the IP Device.

Graphite on other machine
by Martin.Jaburek＠cah.cz 07 Apr '14

07 Apr '14

Hello, I tried to run graphite on another machine. I was able to redirect statistics collection, but I cannot see graph data: I have made changes in etc/graphite.conf: [carbon] # # NAV supports Carbon's UDP line receiver. Host and port information of # the backend can be configured in this section. # host = IP port = 2003 [graphiteweb] # # Where is the Graphite web interface located. NAV needs this to get graphs # and data from Graphite. # base=https://IP When I first started NAV, it was configured to use the graphite on the same machine as NAV. It worked. When I changed it and restarted NAV processes it sent statistics to the new IP (I confirmed it via graphite web fronted), but it still tries to access old graphiteweb for rendering graphs, not the one changed in grahpite.conf. Can there be a problém with certificate? (it is self signed one) Isn't it somehow cached in a database?

But I am still experiencing gaps on some graphs. There is one device which suffers from it most - see attached graphs.

Systém metrics are just fine on this device. I checked the 5min graph of ipdevpoll systém metrics and it shows 100 at peak times, what I assume are only nearly 2 minutes. I'm monitoring about 140 devices right now with nav. I think that it is much correlated to my yesterday upgrade to 4.0.0 (from 4.0b5). Since then I can also see attached errors. They were not there when I was on version 4.0b5. It happens only on cisco catalyst 4500/6500 and one type of 3560E.

Which graphs have gaps? Port metrics? System metrics? All of them? How many devices are you monitoring, and what does the runtime of the various ipdevpoll jobs look like? If the 1minstats job is spending more than 1 minute to complete for any device, there may be gaps its graphs, 5 minutes for the 5minstats job. -- Morten Brekkevold UNINETT

NAV authentication with LDAP + MS AD
by Sjøholt Steinar Otto 04 Apr '14

04 Apr '14

Hi We are running NAV with LDAP-authentication against MS ActiveDirectory. This were working fine for a while, but then the issue with case sensitive usernames appeared (Bug#1207722) The fix seems to have broken LDAP authentication with AD completely. As we are a small group of nav-users here, it took a while (and a passwordchange) to discover this. What happens now is that authentication works (for existing users) as long as the user doesn't change his password. Any new passwords will not work (as the LDAP-query against AD keeps failing), BUT the old (cached?) password still works(!) I don't know if this is by design... But it seems a little flawed to me. Since the addition of ":caseExactMatch:" doesn't work with AD, a better solution to Bug#1207722 would be to have NAV check the output of the LDAP-query to get the actual username (with correct casing) and use this to create the user in the database instead of the actual userinput.

Announcement: NAV 4.0.1 released
by Morten Brekkevold 03 Apr '14

03 Apr '14

Because of some critical bug fixes from the 3.15 series, we have also released version 4.0.1, the first maintenance release of the 4.0 series, today. The source code is available for download at Launchpad [1] and a new package for Debian Wheezy has been published in our APT repository [2]. Changes ======= The following reporte bugs have been fixed in the 3.15 series and are part of 4.0.1: * LP#1300117 (Fix for bug 1295092 causes ipdevpoll inventory jobs to crash for Cisco devices) * LP#1301251 (LDAP users with non-ASCII characters in their name cause login page to crash when user lookup method is 'search' (MS AD)) * LP#1301343 (CDP cache is never refreshed on devices that do not respond to CDP-MIB::cdpGlobalLastChange) * LP#1301349 (Module down alerts fail to mention the module's name) * LP#1301794 (LDAP group membership verification crashes with UnicodeDecodeError when username contains non-ASCII chars) A single issue affecting only the 4.0 series was fixed: * LP#1301260 (seeddb prefix edit does not display all fields) Because the 3.15 and 4.0 series are maintained in parallel, you may need to use the -o option if you are executing the `navsyncdb` program manually for schema upgrades.

Announcement: NAV 4.0.0 released
by Morten Brekkevold 27 Mar '14

27 Mar '14

We are proud to present the final NAV 4.0.0 release, now available for download at Launchpad: https://launchpad.net/nav/4.0/4.0.0 Changes ======= As announced when we released the first beta version, NAV 4.0 introduces two major changes. The two big changes are: 1. The complete replacement of Cricket as a 3rd party tool for statistics collection and graphing. NAV 4 collects the statistics using the already existing ipdevpoll SNMP collector, and uses Graphite as a 3rd party service for storing and graphing this data. This also means NAV no longer uses RRDtool for storing time-series data. 2. A full design overhaul of the web interface, using the Foundation CSS framework. The full release notes for this release can be read at [1]. You are also advised to read the updated installation docs at [2]. If you are upgrading from an existing 3.15 installation, you should avoid starting the new NAV version before migrating your old Cricket/RRD-based statistics to Graphite/Whisper. Instructions for this can found at [3]. If you want to upgrade from a 4.0 beta version, be advised that the polling interval for sensor statistics has been changed from 5 minutes to 1 minute. The updated example storage-schemas.conf reflects this. The whisper files under nav/devices/*/sensors/*.wsp must either be resized to include a new 1 minute resolution archive, or be deleted so that Carbon will re-create empty files from the new config. Debian packages =============== Debian packages have been uploaded to our repository, instructions for using the repository are still found at [4]. NAV's documentation does not cover installation of Graphite's Carbon daemon and the Graphite web interface, which are necessary dependencies in NAV 4.0; it only mentions configuration measures. We have backported a graphite-web package, as it is not provided by the Debian Wheezy distribution. This package does not automatically set up a Graphite web instance for you. We will write a guide suggesting how to do so, but it will be largely based on the shell script we use to automatically build our published virtual appliance. This shell script can be viewed at [5] (ca. lines 35-80). NAV 3.15 support ================ We will continue to support the 3.15 series at least until NAV 4.1 is released, but we recommend all new users to start with NAV 4. Happy NAVing everyone!

Hi, I just checked my ipdevpoll.log and found exception listed bellow. It is a Cisco 3750 two members stack. This error was reported only two times today.

Nav Django exposing Username/Password in error case
by Mischa Diehm 26 Mar '14

26 Mar '14

Hi, I was playing around with ldap/AD integration and got this errorreport mailed to our NOC-Group (see below) - this mail leaks my username/password in cleartext. I think this should really be avoided for any case happening! I don't have a clue about django but a quick search showed me this: https://docs.djangoproject.com/en/dev/howto/error-reporting/ Especially interesting might be this part: ... Filtering sensitive information <https://docs.djangoproject.com/en/dev/howto/error-reporting/#filtering-sens itive-information> Error reports are really helpful for debugging errors, so it is generally useful to record as much relevant information about those errors as possible. For example, by default Django records the full traceback <http://en.wikipedia.org/wiki/Stack_trace> for the exception raised, each traceback frame <http://en.wikipedia.org/wiki/Stack_frame> ¹s local variables, and the HttpRequest <https://docs.djangoproject.com/en/dev/ref/request-response/#django.http.Htt pRequest> ¹s attributes <https://docs.djangoproject.com/en/dev/ref/request-response/#httprequest-att ributes> . However, sometimes certain types of information may be too sensitive and thus may not be appropriate to be kept track of, for example a user¹s password or credit card number. So Django offers a set of function decorators to help you control which information should be filtered out of error reports in a production environment (that is, where DEBUG <https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-DEBUG> is set to False): sensitive_variables() <https://docs.djangoproject.com/en/dev/howto/error-reporting/#django.views.d ecorators.debug.sensitive_variables> and sensitive_post_parameters() <https://docs.djangoproject.com/en/dev/howto/error-reporting/#django.views.d ecorators.debug.sensitive_post_parameters> . ... I wonder if than can be integrated for NAV or if there is another way to get around exposure like that? Mischa Original mail we became for django error: ---- Traceback (most recent call last): File "/usr/lib/python2.7/dist-packages/django/core/handlers/base.py", line 111, in get_response response = callback(request, *callback_args, **callback_kwargs) File "/usr/lib/pymodules/python2.7/nav/web/webfront/views.py", line 89, in login return do_login(request) File "/usr/lib/pymodules/python2.7/nav/web/webfront/views.py", line 122, in do_login account = auth.authenticate(username, password) File "/usr/lib/pymodules/python2.7/nav/web/auth.py", line 95, in authenticate auth = ldapauth.authenticate(username, password) File "/usr/lib/pymodules/python2.7/nav/web/ldapauth.py", line 120, in authenticate lconn = open_ldap() File "/usr/lib/pymodules/python2.7/nav/web/ldapauth.py", line 76, in open_ldap server = _config.get('ldap', 'server') File "/usr/lib/python2.7/ConfigParser.py", line 618, in get raise NoOptionError(option, section) NoOptionError: No option 'server' in section: 'ldap' <WSGIRequest path:/index/login/, GET:<QueryDict: {}>, POST:<QueryDict: {u'origin': [u''], u'username': [u'diehm-adm'], u'password': [u'godDamnitDjango']}>, COOKIES:{'sessionid': 'd660941ae6b821799dbb47ed41d47009'}, META:{'CONTENT_LENGTH': '52', 'CONTENT_TYPE': 'application/x-www-form-urlencoded', 'DOCUMENT_ROOT': '/usr/share/nav/htdocs', 'GATEWAY_INTERFACE': 'CGI/1.1', 'HTTPS': '1', 'HTTP_ACCEPT': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8', 'HTTP_ACCEPT_ENCODING': 'gzip, deflate', 'HTTP_ACCEPT_LANGUAGE': 'de,en-us;q=0.7,en;q=0.3', 'HTTP_CONNECTION': 'keep-alive', 'HTTP_COOKIE': 'sessionid=d660941ae6b821799dbb47ed41d47009', 'HTTP_DNT': '1', 'HTTP_HOST': 'urz-nav-pet.urz.unibas.ch', 'HTTP_REFERER': 'https://urz-nav-pet.urz.unibas.ch/index/login/', 'HTTP_USER_AGENT': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:28.0) Gecko/20100101 Firefox/28.0', 'PATH_INFO': u'/index/login/', 'PATH_TRANSLATED': '/usr/share/pyshared/nav/wsgi.py/index/login/', 'QUERY_STRING': '', 'REMOTE_ADDR': '131.152.2.16', 'REMOTE_PORT': '59503', 'REQUEST_METHOD': 'POST', 'REQUEST_URI': '/index/login/', 'SCRIPT_FILENAME': '/usr/share/pyshared/nav/wsgi.py', 'SCRIPT_NAME': u'', 'SERVER_ADDR': '131.152.2.216', 'SERVER_ADMIN': 'webmaster@localhost', 'SERVER_NAME': 'urz-nav-pet.urz.unibas.ch', 'SERVER_PORT': '443', 'SERVER_PROTOCOL': 'HTTP/1.1', 'SERVER_SIGNATURE': '<address>Apache/2.2.22 (Debian) Server at urz-nav-pet.urz.unibas.ch Port 443</address>\n', 'SERVER_SOFTWARE': 'Apache/2.2.22 (Debian)', 'SSL_TLS_SNI': 'urz-nav-pet.urz.unibas.ch', 'mod_wsgi.application_group': 'urz-nav-pet.urz.unibas.ch|', 'mod_wsgi.callable_object': 'application', 'mod_wsgi.handler_script': '', 'mod_wsgi.input_chunked': '0', 'mod_wsgi.listener_host': '', 'mod_wsgi.listener_port': '443', 'mod_wsgi.process_group': 'NAV', 'mod_wsgi.request_handler': 'wsgi-script', 'mod_wsgi.script_reloading': '1', 'mod_wsgi.version': (3, 3), 'wsgi.errors': <mod_wsgi.Log object at 0x7fa322859430>, 'wsgi.file_wrapper': <built-in method file_wrapper of mod_wsgi.Adapter object at 0x7fa3228655d0>, 'wsgi.input': <mod_wsgi.Input object at 0x7fa3210d6eb0>, 'wsgi.multiprocess': True, 'wsgi.multithread': True, 'wsgi.run_once': False, 'wsgi.url_scheme': 'https', 'wsgi.version': (1, 1)}> -- Mischa Diehm | Network Operations Center (NOC) UniBasel | UniRechenZentrum (URZ) Klingebergstr. 70 | CH-4056 Basel Tel. +41 61 267 1574 | http://urz.unibas.ch

Can you please advise me, what can I do to make it work? brgds Mat

Migration to new NAV version
by Mischa Diehm 05 Mar '14

05 Mar '14

Hi, we migrated our installation to a new HW and Debian stable (3.14.15-1 -> 3.15.5-1). I got all dump.py data migrated without problems. Now we got a lot of User Accounts and Groups with a lot of different Privilidges attached to them. Is there also a (painless) way of transforming this data into the new installation? Thanks in advance! Mischa -- Mischa Diehm | Network Operations Center (NOC) UniBasel | UniRechenZentrum (URZ) Klingebergstr. 70 | CH-4056 Basel Tel. +41 61 267 1574 | http://urz.unibas.ch

Hardware recommendation
by Mischa Diehm 05 Mar '14

05 Mar '14

Hi, first of all welcome to the list! we (UniBasel) use NAV for quite some while now and are very pleased with the possibilities NAV gives us. We use Debian as OS with the following Setup: root@urz-nav:~# uname -a Linux urz-nav 2.6.32-5-amd64 #1 SMP Fri May 10 09:44:53 UTC 2013 x86_64 GNU/Linux root@urz-nav:~# cat /etc/debian_version 6.0.7 root@urz-nav:~# dpkg -l | grep nav ii nav 2+3.14.15-1 Network Administration Visualized A problem we have since a while is that our system is permanently under a lot of load (mostly CPU bound) and we haven't really found a way to reduce the pressure. The hardware we use is a hp blade (ProLiant BL460c G6) with: Intel(r) Xeon(r) Processor X5550 (4 Cores/ 8 Threats) (8M Cache, 2.66 GHz, 6.40 GT/s Intel(r) QPI) and: root@urz-nav:~# free total used free shared buffers cached Mem: 12321700 11673596 648104 0 387768 9123748 At the moment we have 1460 active Devices (mainly Cisco Switches). Around 30 or 40 are OVERDUE in: https://urz-nav/report/lastupdated So my question is, do you have any good experience with HW-systems that are actually dealing with this amount of devices or is there any tuning possibility (without losing functionality) we could try to reduce the pressure on the system?

Announcement: NAV 4.0 beta 3 released
by Morten Brekkevold 06 Feb '14

06 Feb '14

The third beta release of the NAV 4.0 series is now available for download at Launchpad: https://launchpad.net/nav/4.0/4.0b3 I'm also happy to report that the Norwegian University of Science and Technology and the University of Agder have both signed on as beta testers using the virtual appliance. Here's the changelog summary of today's release: Bugfixes: * LP#1270095 (APC sensors stored at wrong precision) * All VLAN utilization graphs produced error messages in b2. User-visible features and improvements: * Inserted the new NAV logo, and completely reworked the page footer. * New NAV blog feed widget added as default. * UI clean-ups and improvements in front page widgets, login page, Geomap, SeedDB, Messages, PortAdmin, Radius, Syslog Analyzer, IP Device Info, room photo database, personal preferences page and others. * Fixed Internet Explorer 9 brokenness. * Tool descriptions have been completely re-authored, and are now also available as a subheading inside each tool. A Debian package has been uploaded to our APT repository. We have not yet built a new virtual appliance, but you can upgrading your existing one using the regular apt-get route. The updated package introduces a dependency to `python-feedparser`, so you may need to either use 'apt-get dist-upgrade' or 'apt-get install nav' to force an upgrade of the nav package (after issuing 'apt-get update', of course). As usual, please report bugs at https://launchpad.net/nav/+filebug . Happy NAVing everyone! -- Morten Brekkevold UNINETT AS
