prometheus offline data recorder and backfiller

PromQueen

PromQueen made possible to record prometheus metrics offline. PromQueen can, therefore, backfill the recorded data inside a native prometheus database.

PromQueen is composed of two primary tools:

• promrec tapes the metrics in a specified output file.
• promplay backfills the prometheus database from scratch.

PromREC

usage: promrec [<flags>]

Flags:
      --help              Show context-sensitive help (also try --help-long and --help-man).
      --debug             Enable debug mode.
      --gzip              Enable gzip mode.
  -i, --interval=60s      Timeout waiting for ping.
  -u, --umap=UMAP ...     stringmap [eg. service.name=http://get.uri:port/uri].
  -o, --output="metrics"  Output file.
      --version           Show application version.

PromPLAY

usage: promplay [<flags>]

Flags:
      --help                 Show context-sensitive help (also try --help-long and --help-man).
      --debug                Enable debug mode.
      --nopromcfg            Disable the generation of the prometheus cfg file (prometheus.yml)
  -d, --dir="/tmp"           Input directory.
      --version              Show application version.
      --storage.path="data"  Directory path to create and fill the data store under.
      --storage.retention-period=360h
                             Period of time to store data for
      --storage.checkpoint-interval=30m
                             Period of time to store data for
      --storage.checkpoint-dirty-series-limit=10000
                             Period of time to store data for

Notes

As of today PromQueen only supports backfilling inside prometheus local storage. New storage types such as influxdb are not supported.
