logmunch

Install with go install github.com/msiebuhr/logmunch/bin/logmunch.

Somewhat ad-hoc tool for parsing logs in logfmt and json-styles from logentries.

Create a file, ~/.logmunch with a list of providers and their default parameters described as URLs. In particular, logentries' key for pull.logentries.com:

logentries://:xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxxxxxxx@pull.logentries.com/

After that, running logmunch -source logentries:Test/heroku -filter "H12" -limit 10 will fetch ten entries with the text H12 from hosts/Test/heroku in logentries.

logenries:

• https://logentries.com/doc/api-download/

file:

• Defaults to stdin.
• file:///./local.txt to read local files.

Basic use

(I'm not terribly good at keeping README's up to date, so please run logmunch -h to get a current overview.)

// Parse a local file
logmunch -source=file:/./local.log

// Round timestamps and generate compound key X from A and B
logmunch -source=- \
    -round-time=1h \
    -compound=X,A,B

Developer docs

The internal API used for fetching/parsing/filtering/outputting logs is split out from the main binary, so it should be possible to re-use.

Documentation is at godoc.org.
