It is strongly advised to monitor memory usage of the exporter. A graphical interface is available with an API. Let's say you've a 6 nodes cluster and want to replace 2nd node (cassandra-1) because of corrupted data. As this deployment contains multiple applications we recommend you use an automation system such as Ansible or Helmfile to put together the config. Work fast with our official CLI. Cassandra is designed for write-intensive workloads, hence, making Elassandra suitable for applications where a large amount of data is to be inserted (such as infrastructure logging, IOT, or events). If you're using Prometheus Operator, you can automatically scrap metrics from Cassandra exporter this way: If you're using Prometheus Operator, you can automatically have some default alerts through Alertmanager.

You can use this mechanism effortlessly since it is already well developed. As we don't want this kind of situation to happen in production, the scrape frequency is restricted via the configuration of Cassandra Exporter. Our application containers are designed to work well together, Important: scraping outside the statefulset can multiply x10 the scraping time. Helm is a package manager for kubernetes and works based on a template(similar to Terraform) makes it super easy to install the software in kubernetes. How to deploy Apache Cassandra on Kubernetes with AxonOps management tool. download the GitHub extension for Visual Studio.

By testing a thousand instances of Cassandra, we could make sure that Kubernetes 1.3 was production ready. Also add the Traefik Ingress repo - you’ll need its resources to access services from outside the Kubernetes cluster. It can create, configure, and manage Cassandra clusters running in Kubernetes. The easiest way is to create a new helm chart to manage these init scripts. The “release” includes files with Kubernetes-needed resources and files that describe the installation, configuration, usage and license of a chart. To list backups for a statefulset instance, connect to an instance like in this example and call the script: To restore backups, configure properly the "restoreFolder" var and run this command. This Dashboard version is made for Cassandra running on top of Kubernetes.

K8ssandra consists of the aforementioned Cass-operator Kubernetes operator built and open sourced by DataStax, pre-built and pre-configured integrations with both Prometheus and Grafana, and two tools that came to Cassandra as part of the Last Pickle acquisition: Cassandra Reaper, an anti-entropy repair tool, and Cassandra Medusa, a data backup and restore tool. Backups. In Kubernetes, there is a PersistentVolume for storing data. In March, DataStax released its Operator system , which provides a manifest that automates deployment of an application or service into a Kubernetes cluster.
