Hi Felipe, You can use this project https://github.com/criteo/cassandra_exporter if you are using Prometheus (Disclamer, I am one of the author of it). There is included a Grafana dashboard that aggregate metrics per cluster for you, and in the "edit view" of each chart there are hidden queries that let you drill down by nodes. In any case, you can look at the json in order to grasp how to aggregate queries.
Let me know if you need more information regarding the setup. If you end-up using the project, give a star to the project it is always pleasant, Regards, Romain Gérard On Jun 18 2018, at 3:25 pm, Felipe Esteves <felipe.este...@b2wdigital.com> wrote: > > Hi, everyone, > > I'm running some tests to monitor Cassandra 3.x with jmx_exporter + > prometheus + grafana. > I've managed to config it all and use the dashboard > https://grafana.com/dashboards/5408 > > However, I still can't aggregate metrics from all my cluster, just nodes > individually. > Any tips on how to do that? > > Also, Opscenter gives some datacenter aggregation, I think it comes from > nodetool as I didn't seen any metrics about that. > Anyone having success on that? > > cheers! > Em qua, 28 de jun de 2017 às 19:43, Petrus Gomes <petru...@gmail.com > (mailto:petru...@gmail.com)> escreveu: > > I'm using JMX+Prometheus and Grafana. > > JMX = https://github.com/prometheus/jmx_exporter > > Prometheus + Grafana = https://prometheus.io/docs/visualization/grafana/ > > > > There are some dashboard examples like that: > > https://grafana.com/dashboards/371 > > Looks good. > > > > > > Thanks, > > Petrus Silva > > > > > > > > > > On Wed, Jun 28, 2017 at 5:55 AM, Peng Xiao <2535...@qq.com > > (mailto:2535...@qq.com)> wrote: > > > Dear All, > > > > > > we are currently using Cassandra 2.1.13,and it has grown to 5TB size with > > > 32 nodes in one DC. > > > For monitoring,opsCenter does not send alarm and not free in higher > > > version.so we have to use a simple JMX+Zabbix template.And we plan to use > > > Jolokia+JMX2Graphite to draw the metrics chart now. > > > > > > Could you please advise? > > > > > > Thanks, > > > Henry > > > > > > > > > > > > Esta mensagem pode conter informações confidenciais e somente o indivíduo > > ou entidade a quem foi destinada pode utilizá-la.
