Warning from eventengine - topology problem
by Ingeborg Hellemo 20 Feb '13

20 Feb '13

NAV 3.13.0 Eventengine logs a lot of topology problems of two kinds. One regarding the NAV-server itself: 2013-02-18 11:23:37,173 [WARNING nav.eventengine.topology] NAVServer('129.242.5.182') topology problem: router ma-gsw3.infra is up, but not in VLAN graph for <Prefix: 129.242.5.0/24 (vlan 103 (nett,srv,5-nettet))>. Defaulting to 'reachable' status. The other kind regarding some (but not all) random devices: 2013-02-18 11:23:37,740 [WARNING nav.eventengine.topology] nfh-b100-nc.prn topology problem: router nfh-gsw.infra is up, but not in VLAN graph for <Prefix: 10.253.19.0/24 (vlan 600 (uit,prn))>. Defaulting to 'reachable' status. Is there anything we can do to in our setup to eliminate the warnings (except changing the debug level...)? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

NetworkXNoPath: No path between server and router

We are running NAV 3.13.0 since 08.02.13 Some days ago something happened in our environment that caused eventengine to throw an error: 2013-02-13 17:08:57,887 [ERROR nav.eventengine.engine] Unhandled exception in plugin <nav.eventengine.plugins.boxstate.BoxStateHandler object at 0x804e170d0> ; ignoring it Traceback (most recent call last): File "/usr/local/nav/lib/python/nav/eventengine/engine.py", line 190, in handle_event handler.handle() File "/usr/local/nav/lib/python/nav/eventengine/plugins/delayedstate.py", line 52, in handle return self._handle_start() File "/usr/local/nav/lib/python/nav/eventengine/plugins/delayedstate.py", line 68, in _handle_start self._set_internal_state_down() File "/usr/local/nav/lib/python/nav/eventengine/plugins/boxstate.py", line 29, in _set_internal_state_down shadow = self._verify_shadow() File "/usr/local/nav/lib/python/nav/eventengine/plugins/delayedstate.py", line 189, in _verify_shadow netbox.up = (Netbox.UP_DOWN if netbox_appears_reachable(netbox) File "/usr/local/nav/lib/python/nav/eventengine/topology.py", line 32, in netbox_appears_reachable target_path = get_path_to_netbox(netbox) File "/usr/local/nav/lib/python/nav/eventengine/topology.py", line 82, in get_path_to_netbox path = networkx.shortest_path(graph, netbox, router) File "/usr/local/lib/python2.7/site-packages/networkx-1.6-py2.7.egg/networkx/ algorithms/shortest_paths/generic.py", line 124, in shortest_path paths=nx.bidirectional_shortest_path(G,source,target) File "/usr/local/lib/python2.7/site-packages/networkx-1.6-py2.7.egg/networkx/ algorithms/shortest_paths/unweighted.py", line 138, in bidirectional_shortest_path results=_bidirectional_pred_succ(G,source,target) File "/usr/local/lib/python2.7/site-packages/networkx-1.6-py2.7.egg/networkx/ algorithms/shortest_paths/unweighted.py", line 205, in _bidirectional_pred_succ raise nx.NetworkXNoPath("No path between %s and %s." % (source, target)) NetworkXNoPath: No path between <server> and <router> This happened for 5 servers all on the same GSW. Four days later 4 of them are still marked as down even though ipdevinfo reports availability numbers like the following and the servers clearly are up: Availability 100.00% last day, 99.77% last week, 99.94% last month Where do I have to push (or kick) to make NAV recognise the servers as up? --Ingeborg -- Ingeborg Østrem Hellemo -- ingeborg.hellemo(a)uit.no Dep. of Information Technology --- Univ. of Tromsø

Announcement: NAV 3.13.0 final released
by Morten Brekkevold 07 Feb '13

07 Feb '13

A beta version of the next NAV feature release, version 3.13.0b1, is now available for download at Launchpad: https://launchpad.net/nav/3.13/3.13.0b1 The 3.13.0b1 release adds the following user-visible features and improvements: * The eventEngine has been rewritten to Python. This was the last remaining Java component of NAV, meaning Java is no longer needed for installing and running NAV. * VLANs are now searchable from the Navbar. * IPv4, IPv6 and MAC host counts for each VLAN is now graphed over time. * NAV is now able to detect and graph data from sensors on Cisco Nexus devices. * Maintenance tasks can now be configured to end automatically when all components involved in the task are up. * IP Devices that are down can be placed on immediate maintenance until up again directly from the status page. * Subscriptions to MAC address prefixes are now possible in Macwatch. Use with caution! And contains fixes for these reported issues: * LP#305435 (Sort by "Start time" or "End time" in machinetracker) * LP#305441 (Button for "Put on maintenance immediately") * LP#317800 (Color gradient to express utilization of IPv6 subnets) * LP#341703 (Manual detention does not pursue client) * LP#361530 (Arnold: Predefined detention does not exponentially increase detentions) * LP#744932 (Arnold should give warning if snmp write is not configured) * LP#833959 (make install overwrites nav.conf and db.conf) * LP#922793 (Possibility to set end time = "until device is up again " in maintenance) * LP#961097 (Don't list cancelled maintenance tasks in active list) * LP#961100 (Show component details in maintenance task list when there is only a single component) * LP#1057509 (Mouseovers with number of active IPv6 addresses in Subnet Matrix) * LP#1057511 (Get sensor information from CISCO-ENTITY-SENSOR-MIB) * LP#1062130 (NAV should graph IP address usage per prefix) * LP#1069773 (macwatch should be able to look for MAC address prefixes too) Remember, this is still beta status, and should not necessarily be considered production ready. 3.13 features two major rewrites, one for the eventengine one for the port blocker, Arnold. If you want to help us test the beta version, you are most welcome. Don't forget to check out the release notes, and please report bugs at https://launchpad.net/nav/+filebug :-) Binary packages for Debian will be made available as soon as possible.
