logmerge

logmerge merges multiple log files into a single stream, preserving the total ordering of events across the multiple log files.

Features

• Supports multiple timestamp formats
  • Date and time with either fractional seconds or comma-separated milliseconds
  • Integer or floating point time_t (base-1970)
• Can tag each merged line with an arbitrary text tag per source log
• Can color-code lines per log (using ANSI escape sequences)

Limitations

• Assumes all timestamps are UTC. The currently-supported timestamp formats don't support a timezone tag.
• Timestamps are not reformatted. If merged logs use different timestamp formats, the merged log will expose that.
