Elasticsearch 5.x Solutions - Node and Cluster Management

Managing Clusters and Nodes 6 lectures 26:16 The Course Overview This video gives an overview of the entire course. Controlling Cluster Health and State Via an API Elasticsearch provides a convenient way to manage the cluster state, which is one of the first things to check if any problems occur. If you need more details on your cluster, you need to query its state. • View the cluster health • Learn the cluster status of Elasticsearch • View the cluster state Getting Nodes Information and Statistics Via API In production clusters, it's very important to monitor nodes via this API to detect misconfiguration and problems relating to different plugins and modules. • Retrieve the node information • Truncate repetitive parts • Retrieve the node statistic Using the Task Management and the Hot thread API When some actions are called, they create a server side task that executes the job. The task management API allows you to control these actions. Sometimes, your cluster slows down due to massive CPU usage and you need to understand why. • Retrieve the node information • Get the task information Managing the Shard Allocation Sometimes, due to massive relocation, or due to nodes restarting or some other cluster issues, it's necessary to monitor or define custom shard allocation. • Retrieve the cluster allocation information Monitoring Segments and Clearing the Cache Monitoring the index segments means monitoring the health of an index. Cleaning the cache helps to speed up searching, such as cache results, items and filter results. • Retrieve the index segments • Call the cleancache API on an index Managing Clusters and Nodes 6 lectures 26:16 The Course Overview This video gives an overview of the entire course.

The restore is only forward-compatible. So, we need reindexing from a remote cluster. • Add the remote server address • Restart the Elasticsearch node to take the new configuration • Call the reindex API to copy a test-source index data in a test-dest via the remote REST endpoint Backup and Restore. 4 lectures 12:21 Managing Repositories An Elasticsearch snapshot allows for the creation of snapshots of individual indices (or aliases), or an entire cluster, into a remote repository nge to be used for Elasticsearch.
