Description
Feature Request
Summary
When Promethus is enabled in the manifest, create automatically a configuration file for Prometheus that includes essential settings and the IP addresses of the nodes in the manifest.
For example, for test/e2e/networks/simple.toml, which has 4 nodes, the content of the yaml file could be:
global:
scrape_interval: 1s
scrape_configs:
- job_name: 'validator01'
static_configs:
- targets: ['localhost:6701']
- job_name: 'validator02'
static_configs:
- targets: ['localhost:6702']
- job_name: 'validator03'
static_configs:
- targets: ['localhost:6703']
- job_name: 'validator04'
static_configs:
- targets: ['localhost:6704']
