When you run TPstats or Tablestats subcommands in nodetool you are actually accessing data inside Cassandra via JMX.

You can start there at first.

Hi,

Please, how can check the health of my cluster / data center using cassandra ?
In fact i'd like to generate a hitory of the state of each node. an history about the failure of my cluster ( 20% of failure in a day, 40% of failure in a day etc...)

Thank you so much.
Kind regards.
