Still no IS-IS topology monitor?
I started making a very basic implementation which can show ISIS-enabled adjacencies and their status. This is still a work in progress but might prove useful.

Adds a very basic ISIS-protocol support with the functionality to poll configure… d adjacencies. This information may be used to trigger alarms when the device loses any of the configured adjacencies. Also adds a simple table for device and routing contexts that can be used to view the general status of the topology. Also, links are created on the UI where possible - requires that the device's ifIndexes are saved into the DB.
Each polled adjacency is saved into the DB during the first time it is seen. When polled again, the old record is matched and updated by local ifIndex + device_id as a unique identifier. If the port has ISIS configuration but there has never been any adjacents, this saves only the ifIndex and marks it's status as down.
==> Tested with Juniper MX-80, MX-240 and Cisco ASR9K-series routers. Seems to poll all configured adjacencies
- [x] Basic polling support (== Adjacencies and their status can be polled to some extent)
- [x] Adjacencies can be saved into the DB
- [x] Basic tables in device and routing menus
- [x] Module can be enabled from polling options
- [x] Translations for settings
- [x] Alert fault listing (functions.inc.php) by adjacency IP - could also generate links if the adjacency is found in NMS
- [x] Routing menubar link
- [x] Add alert template for adjacency status check
- [x] Device menubar link
- [x] Cleanup options from poller module (missing as in extra entries that exist in the DB but do not exist on the poll. These entries should be purged from the DB)
- [x] Code style fixes
- [x] Generate links on routing page pages where possible (point interfaces and / or IPs to the devices in question if they exists on the NMS)
- [x] Remove entries from the DB when the device is deleted
- [x] Data formatting
- [x] Database schema and migrations
- [x] Convert pollert module to new style
- [x] Test cases
