Hi Juho, Out of curiosity, which stack did you use to make your dashboard? Romain Le Jeudi 14 juillet 2016 10h43, Juho Mäkinen <juho.maki...@gmail.com> a écrit :
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. - Garo On Thu, Jul 14, 2016 at 10:54 AM, Romain Hardouin <romainh...@yahoo.fr> wrote: 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.)

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.
