supergrep

Supergrep is a web based log streamer written in node. It can be used quite nicely to surface new log lines (errors, etc.) that aren't normally expected.

Essentially, having supergrep running in your browser while changes are being made allows for new/novel log patterns to show up, because under the hood, what we're really doing is:

$ tail -f {log filename} | grep -v {stuff you'd expect to see in log lines}

It's intended on being a noise reduction and change-awareness tool.
