Just copy the configurations and start the applications where you have them extracted. In my case the issue stems from the fact that my Cassandra cluster and node-exporter services are built via docker-compose which means they each get their own unique server IP on swarm's overlay network. MCAC is deployed to your Kubernetes environment by K8ssandra. Users may enable, and configure, AlertManager through the values.yaml file. While it is preferable to run cassandra-exporter as a Java agent for performance, it can instead be run as an external application if required. There are three aspects to running solr-exporter: Modify the solr-exporter-config.xml to define the data to collect. Cassandra exporter is a standalone application which exports Apache Cassandra metrics throught a prometheus friendly endpoint. All other keyspace- and node-level When running applications in Kubernetes, observability is key. You either need to set the SQL Login's default database to the correct location or you need to include it in your query (if such a tool as sql_exporter allows it), e.g. Develop an actionable cloud strategy and roadmap that strikes the right balance between agility, efficiency, innovation and security. Create storage and start Prometheus. MCAC can track over 100k unique metric series per node. Early versions supported outputting metrics as a HTML document for easier viewing in a browser. See Instaclustr's repo for releases. The exporter attempts to follow Prometheus' best practices for metric names, labels and data types. We'll demo all the highlights of the major release: new and updated visualizations and themes, data source improvements, and Enterprise features. As an example, if we take as input set the metrics {a, b, c} and the config file is. An essential design choice the project makes is to not let prometheus drive the scraping frequency. cassandra-exporter enables high performance collection of Cassandra metrics and follows the Prometheus best practices for metrics naming and labeling. I need this configuration for Cassandra monitoring with grafana dashboards . K8ssandra provides a ServiceMonitor for Stargate when it is enabled. Cassandra's support for replicating across multiple datacenters is best-in-class, providing lower latency for your users and the peace of mind of knowing that you can survive regional outages. You can have a look at a full configuration file here Configure Prometheus to scrape the endpoint by adding the following to prometheus.yml: See the Prometheus documentation for more details on configuring scrape targets.

The AlertManager is an additional resource provided by kube-prometheus-stack that can be configured to specify thresholds for specific metrics that will trigger alerts. Start the exporter from within Solr. To view the raw, plain text metrics (in the Prometheus text exposition format), request the endpoint Individual time-series are separated by different labels. In Kubernetes, racks are represented as StatefulSets. Why this exporter is slower than jmx_exporter ? Unlike the metrics exported via JMX, where each table metric has a unique name, Cassandras metrics are coalesced when appropriate so they share the same exported metric family name, opting for labels to differentiate individual time series. But still provides quite a lot of information to get you started. OurSite Reliability Engineeringteams efficiently design, implement, optimize, and automate your enterprise workloads.

Not yet. aggregate metrics, specifically histograms, are exposed by cassandra-exporter. Very well documented, Thanks. * does not expose any metrics but are used to trigger actions on Cassandra's nodes. This blog assumes that you have a working Cassandra cluster. To do this, we define two additional elements: This is an array that defines one or more JSON Queries in jq syntax. *:95thpercentile - . Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. For example, the following PromQL query will return an estimate of the number of pending compactions per-keyspace, per-node.
