# Short-Description: Extract monitoring data from logs
# Description: mtail is a tool for extracting metrics from application
# logs to be exported into a timeseries database or
# timeseries calculator for alerting and dashboarding.
# It aims to fill a niche between applications that do not
# export their own internal state, and existing monitoring
# systems, without patching those applications or rewriting
# the same framework for custom extraction glue code.
# Metrics are exported for scraping by a collector as JSON
# or Prometheus format over HTTP, or can be periodically
# sent to a collectd, StatsD, or Graphite collector socket.
