gnomon

Utility to annotate console logging statements with timestamps and find slow processes.

• Use UNIX (or DOS) pipes to pipe the stdout of any command through gnomon:

{npm test} | gnomon

• Show number of seconds since the start of the process:

{npm test} | gnomon --type=elapsed-total

• Show an absolute timestamp in UTC:

{npm test} | gnomon --type=absolute

• Set a high threshold of 0.5 seconds for the elapsed time; exceeding which the timestamp will be colored bright red:

{npm test} | gnomon --high {0.5}

• Set a medium threshold of 0.2 seconds (Timestamp will be colored bright yellow):

{npm test} | gnomon --medium {0.2}
