Witness Essentials: Watcher v1.0.2

Witness Essentials: Watcher received an update, which includes:

• New command: test which can be used to test notifications & failover in case of missed blocks.
• After a specific time, since the last missed block (1 day default), key-rotation rounds and the missed block threshold will be reset to prevent unnecessary failover
• The interval variable inside config.json is in minutes but has been in seconds in code. This has been changed to minutes now.

Update Information

• Update your packages if you're running it locally (npm update/yarn)
• Add "MAX_AGE_LAST_MISSED_DAYS": 1 to your config.json. 1 is the default value and should be replaced depending how long it takes for your witness to produce a block.
• For testing, simply run: npm run test or yarn run test. You're then able to choose between testing failover via real key signing (+ choose if you want to skip disabling of witness) and testing notifications.
• Make sure the interval(minutes) inside config.json is correctly set

Quick note: the test command is currently not available via docker, only directly via npm/yarn.

Alright, that's it regarding the new update.

I hope my fellow witnesses find this useful as monitoring & watching your witness-nodes is quite important.

All the best,
Wolf
