REMIX EXAMPLE PROJECT
Remix example project is present when Remix loads very first time or there are no files existing in the File Explorer.
It contains 3 directories:
1. 'contracts': Holds three contracts with different complexity level, denoted with number prefix in file name.
2. 'scripts': Holds two scripts to deploy a contract. It is explained below.
3. 'tests': Contains one test file for 'Ballot' contract with unit tests in Solidity.

d10r / artis_monitor_running.sh
Created July 18, 2020 11:34
minimal script for stateless monitoring/alerting (stall detection) for an Ethereum/ARTIS node via its RPC interface
#!/bin/bash
# Statelessly checks if the given chain (identified by its rpc) is running.
# Definition of running: the most recent block was authored less than the given number of seconds ago
#
# argument $1: URL to the RPC node to query
# argument $2: threshold for how old - in seconds - the most recent block may be. If older, the chain is considered as not running
# argument $3: space separated list of recipients the Email alert should go to
#
# Note that this script is not designed to give any feedback about what's wrong in case it fails. It just sounds an alarm if it doesn't run through as expected.
