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

  • 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}}
