Localnet Monitor

The Localnet Monitor is a small program that simply polls localnet for values that we want to test against.

Prerequisites

• Go 1.26+
• docker available in your cli

Running

You can run the Localnet Monitor like so, this will read from localnet and print a table that refreshes every 1 second.

Make sure you have localnet running:

from the root of the repo:

docker build -f ./e2e/optimism-stack.Dockerfile -t optimism-stack:latest .
docker compose -f ./e2e/docker-compose.yml down -v --remove-orphans
docker compose -f ./e2e/docker-compose.yml up

NOTE: The --remove-orphans flag should remove other containers not defined in the docker compose file. This is mainly here to help ensure you start with a clean environment. It can be omitted.

from this directory:

$  go run ./...

If you would like to print the results as json, you can give the json "snapshot" a delay via the env variable HEMI_E2E_DUMP_JSON_AFTER_MS, after these milliseconds, values will be read and dumped.

$ HEMI_E2E_DUMP_JSON_AFTER_MS=10000 go run ./...
