Although pt-heartbeat should work with all supported versions of Percona XtraDB

Cluster (PXC), we recommend using 5.5.28-23.7 and newer.

If you are setting up heartbeat instances between cluster nodes, keep in mind
|

that, since the speed of the cluster is determined by its slowest node,
|
||||
pt-heartbeat will not report how fast the cluster itself is, but only how
|
||||
fast events are replicating from one node to another.
