Leap Network Monitoring λ

Installation

yarn

If you don't already have the serverless cli installed, do that

yarn global add serverless

If it's the first time you use aws, you need to configure credentials

https://github.com/serverless/serverless/blob/master/docs/providers/aws/guide/credentials.md

Configuration

Some of these have default values per network, see npm scripts in package.json.

• SLACK_HOOK. Slack hook URL
• SLACK_CHANNEL. Slack channel/DM to post to (e.g. #mainnet or @kosta)
• NODE_URL. Leap JSON RPC url
• ENV. Environment e.g. mainnet or testnet
• SAFE_BLOCK_TIME. Number of seconds between blocks considered as OKAY. Alert will be triggered, if there is no block produced in SAFE_BLOCK_TIME seconds
• SAFE_PERIOD_TIME. Number of seconds between periods considered as OKAY. Alert will be triggered, if there is no period submitted in SAFE_PERIOD_TIME seconds.
• VAL_BALANCE_THRESHOLD. Minimum safe amount of Ether for validator balance (in wei). Alert will be triggered, if the balance is lower than VAL_BALANCE_THRESHOLD. If ommited, the default value will be used which should be enough to submit 10 periods with 20 gwei gas price.
