-=========================================================
- rbd-replay -- replay rados block device (RBD) workloads
-=========================================================
-
-.. program:: rbd-replay
-
-Synopsis
-========
-
-| **rbd-replay** [ *options* ] *replay_file*
-
-
-Description
-===========
-
-**rbd-replay** is a utility for replaying rados block device (RBD) workloads.
-
-
-Options
-=======
-
-.. option:: -c ceph.conf, --conf ceph.conf
-
- Use ceph.conf configuration file instead of the default /etc/ceph/ceph.conf to
- determine monitor addresses during startup.
-
-.. option:: -p pool, --pool pool
-
- Interact with the given pool. Defaults to 'rbd'.
-
-.. option:: --latency-multiplier
-
- Multiplies inter-request latencies. Default: 1.
-
-.. option:: --read-only
-
- Only replay non-destructive requests.
-
-.. option:: --map-image rule
-
- Add a rule to map image names in the trace to image names in the replay cluster.
- A rule of image1@snap1=image2@snap2 would map snap1 of image1 to snap2 of image2.
-
-.. option:: --dump-perf-counters
-
- **Experimental**
- Dump performance counters to standard out before an image is closed.
- Performance counters may be dumped multiple times if multiple images are closed,
- or if the same image is opened and closed multiple times.
- Performance counters and their meaning may change between versions.
-
-
-Examples
-========
-
-To replay workload1 as fast as possible::
-
- rbd-replay --latency-multiplier=0 workload1
-
-To replay workload1 but use test_image instead of prod_image::
-
- rbd-replay --map-image=prod_image=test_image workload1
-
-
-Availability
-============
-
-**rbd-replay** is part of Ceph, a massively scalable, open-source, distributed storage system. Please refer to
-the Ceph documentation at http://ceph.com/docs for more information.
