streamlog

Local log viewer supporting filtering and highlighting all in a single elixir script, using Phoenix Live View through phoenix_playground.

• Regex based filtering and highlighting
• Filtered out logs are retained (until streamlog runs)

tail -f some-log-file | <path-to>/streamlog.exs --open --port 9090 --title 'some-log-file logs'

Usage

Download streamlog.exs and ensure is executable chmod+x

tail -f some-log-file | <path-to>/streamlog.exs --open --port 9090 --title 'some-log-file logs'

or

./some-program-loggin-on-stdout | <path-to>/streamlog.exs --port 9091 --title 'program logs'

Options

• --port to run on a different port than the defaul (5051)
• --title to assign a title to the page
• --open open Streamlog in the browser

Technicalities

• logs are stored in an ets table in memory.
• streamlog exposes Phoenix Live Dashboard on /dashboard for debug purpose and curiosity.
