This chapter talks about the Elasticsearch monitoring plugins Elasticsearch-head and Bigdesk, along with the Elasticsearch cat API. These utilities are used to assess the status of your cluster and to diagnose issues:
Elasticsearch-head: This is used to get an idea of your overall cluster health, individual node status, and an understanding of your indices
Bigdesk: This is used to look into the memory, disk, and CPU usage of individual nodes in your cluster
Elasticsearch cat API: This lets you access many of Elasticsearch's internal metrics without installing any plugins
Specifically, this chapter explores the following:
Configuring an Elasticsearch cluster
Loading sample data into Elasticsearch
Using Elasticsearch-head
Using Bigdesk
The Elasticsearch cat API
