No, you dont need to install Prometheus on each node. Install Prometheus on
one machine and configure it. For basic configuration use this

You need to use exporter on each node for collecting metrics.
Node exporte
Hi all;
Please, i have a history of the state of each node in my data center. an
history about the failure of my cluster (UN: node up, DN: node down).
Here is some lines of the history:
08:51:36 UN 127.0.0.1
08:51:36 UN 127.0.0.2
08:51:36 UN 127.0.0.3
08:53:50 DN 127.0.0.1

Running nodetool status is okay if you want the simplest solution.
But it generates a lot of output and creates a new JMX connection for every
execution.
Cassandra uses JMX to expose metrics via mbeans.

Hi,
Thank you so much for answers.
Please, can you explain more what's metric libraries ? and give me some
examples ?
Using nodetool status, to generate the history of my data center, i intend
to proceed as follows:
>From a node A:
For i 1 ..24 hours (every 2 minutes do)
./nodetool status >>
Hi,
Yes, you can use nodetool status to inspect the health/status of the
cluster. Using *nodetool status * will show the cluster
health/status as well as the amount of data that each node has for the
specified **. Using *nodetool status* without the
argument will only show the cluster health/sta
Hi,
Thank you so much for answer.
Please, is it possible to use this command ?
nodetool status mykeyspace
Datacenter: datacenter1
===
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
-- AddressLoad Tokens OwnsHost ID
Rack
UN 127.0.0.1 47.66 KB
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.
