Hello,
Sorry for the delay of response, I am right now in Nepal for 2 weeks,
so my internet connectivity is not that much available.
@Lucas BenevidesYou can't try Criteo, or maybe you can if you want to
join my company :). I will suppose you meant Prometheus, in this case
you will need to setup a separate infrastructure than just the exporter
I announced.I encourage you to look at https://prometheus.io/docs/intro
duction/overview/ to understand the architecture of Prometheus.The
cassandra_exporter is only there to provide a valid prometheus endpoint
(an http server with /metrics) that your prometheus will scrap.So you
indeed need to run one exporter on each cassandra node you
have.Regarding you doubt toward Prometheus, we are using it to monitor
>2000 machines in our team and so far we are very happy with it.P.S:
Grafana now support prometheus as a data source

Regards,Romain
