- * This is used to send pings between daemons (so far, the OSDs) for
- * heartbeat purposes. We include a timestamp and distinguish between
- * outgoing pings and responses to those. If you set the
- * min_message in the constructor, the message will inflate itself
- * to the specified size -- this is good for dealing with network
- * issues with jumbo frames. See http://tracker.ceph.com/issues/20087
