Hi Juho,
Out of curiosity, which stack did you use to make your dashboard?

I'm doing some work on replacing OpsCenter in out setup. I ended creating a
Docker container which contains the following features:
- Cassandra 2.2.7 - MX4J (a JMX to REST bridge) as a java-agent -
metrics-graphite-3.1.0.jar (export some but not all JMX to graphite) - a custom
ruby which uses MX4J to export some JMX metrics to graphite which we don't
otherwise get.
With this I will get all our cassandra instances and their JMX exposed data to
graphite, which allows us to use Grafana and Graphite to draw pretty dashboards.
In addition I started writing some code which currently provides the following
features: - A dashboard which provides a similar ring view what OpsCenter does,
with onMouseOver features to display more info on each node. - Simple HTTP
GET/POST based api to do - Setup a new non-vnode based cluster - Get a
JSON blob on cluster information, all its tokens, machines and so on - Api
for new cluster instances so that they can get a token slot from the ring when
they boot. - Option to kill a dead node and mark its slot for replace, so
the new booting node can use cassandra.replace_address option.
The node is not yet packaged in any way for distribution and some parts depend
on our Chef installation, but if there's interest I can publish at least some
parts from it.

Do you run C* on physical machine or in the cloud? If the topology doesn't
change too often you can have a look a Zabbix. The downside is that you have to
set up all the JMX metrics yourself... but that's also a good point because you
can have custom metrics. If you want nice graphs/dashboards you can use Grafana
to plot Zabbix data. (We're also using SaaS but that's not open source).For the
rolling restart and other admin stuff we're using Rundeck. It's a great tool
when working in a team.
(I think it's time to implement an open source alternative to OpsCenter. If
some guys are interested I'm in.)
Best,
Romain

we use datadog (metrics emitted as raw statsd) for the dashboard. All repair &

Now that OpsCenter doesn't work with open source installs, are there any runs
at an open source equivalent? I'd be more interested in looking at metrics of a
running cluster and doing other tasks like managing repairs/rolling restarts
more so than historical data.
