This extension provides the ability to remotely monitor your Elasticsearch Clusters, Nodes, and Indexes using Prometheus metrics ingested minutely. You can use the unified analysis screens to analyze Elasticseach clusters' health and drill down into individual metrics to identify the root cause of potential performance issues.

This is intended for users, who:

• Want to monitor the health and performance of their Elasticsearch Clusters, Nodes, and Indexes.
• Look for analysis support for Ops, IT and Network Admins.

This enables you to:

• Monitor your Elasticsearch infrastructure using comprehensive unified analysis screens and dashboards.
• Enable alerts based on detected anomalies.

This extension uses the Prometheus Elasticsearch Exporter to collect metrics.

First, you'll need to install the Elasticsearch exporter on every host you want to collect metrics for. This can be done by using the prebuild binary or a docker container as seen on the exporter's github page. To get all the metrics this extension can offer, you need to enable the following options on the exporter:

• --es.all
• --es.cluster_settings
• --es.indices
• --es.indices_settings
• --es.indices_mappings
• --es.shards
• --es.snapshots

In Dynatrace, download the Elasticsearch extension and click Add monitoring configuration next to an extension version under the Versions list. Select the host you want to monitor then define the URL to the /metrics endpoint on your Prometheus instance or Elasticsearch exporter on your host. Finally, select the feature sets containing the metrics you want to import.

The Elasticsearch Extension is build on the new Extension 2.0 framework utilizing a Prometheus datasource. The unified analysis screens provide insight into the health and performance of your Elasticsearch clusters.

This extension package contains:

• Prometheus data source configuration for metric ingestion.
• Topology and relationship definitions for Elasticsearch clusters and their Nodes, Indexes, Disks, and Thread Pools.
• Unified analysis screens for every entity (Accessible from the dashboard)
• An overview dashboard
• Alerts for some key metrics

Alerts:

• Total CPU Util > 85%
• Filesystem Usage > 80%
• Open File Descriptors > 80% of Max File Descriptors
• Heap Used > 85%
• Rejected Threads > 300

• This extension provides monitoring of your Elasticsearch resources using the Prometheus exporter for Elasticsearch(see details tab).
  • Note: This exporter needs to be setup and run independently from this extension.
• Root-cause analysis for Elasticsearch cluster, nodes and indexes performance issues.
