How can i see an individual cluster latency?

How can i see an individual cluster latency, number of node up/down, rea/write performance of a cluster in cassandra? Does cassandra stores all these information somewere?

Solution

  • I would suggest looking at the nodetool utility for this information.

    nodetool ring

    will give you the up/down status of the cluster and

    nodetool tablehistograms

    will give you table read/write latencies. Nodetool has many other commands for looking at the cluster or node internals.

    There is a lot of information about it here.
