ANXT Watcher

ANXT Watcher checks the status of Jelurida Ardor and NXT nodes and prints one colour-coded table: application, version, blockchain state, block count and peers for every node in a list.

Requirements

• Python 3 (3.8 or newer recommended)
• Nodes whose API answers getState requests from where you run the tool

Install

git clone https://github.com/ChainTools-Tech/anxt_watcher.git && cd anxt_watcher
python3 -m venv .venv && . .venv/bin/activate
pip install .

Usage

List the nodes in a text file, one per line. Include the API port if it isn't the default for the protocol:

ardor-node-1.example.com:27876
ardor-node-2.example.com:27876
nxt-node.example.com:7876

anxtwatch --file hosts.txt

For each node, ANXT Watcher requests /nxt?requestType=getState over HTTP, and over HTTPS if HTTP fails (10-second timeout each). Up to 10 nodes are queried in parallel, with a progress bar.

Output

A table sorted by host, with these columns: Host, Application, Version, Blockchain State, Number of Blocks, Is Offline, Services, Number of Connected Peers.

The blockchain state is coloured:

Colour	State
Green	UP_TO_DATE
Yellow	DOWNLOADING
Red	Any other state, or ERROR when the node didn't answer (all columns then show ERROR)
