Orientation

A Knowledge Module (KM) is a set of files from which a PATROL Agent receives information about resources running on a monitored computer. A KM file can contain the actual instructions for monitoring objects or simply a list of KMs to load. KMs are loaded by a PATROL Agent and a PATROL Console.

KMs provide information for the way monitored computers are represented in the PATROL interface, for the discovery of application instances and the way they are represented, for parameters that are run under those applications, and for the options available on object pop-up menus. A PATROL Console in developer mode can change KM knowledge for its current session, save knowledge for all of its future sessions, and commit KM changes to specified PATROL Agent computers. A KM file contains the source code for a PATROL application. 

Elasticsearch is a search engine based on Lucene. It provides a distributed, multi-tenant capable full-text search engine with HTTP web interface and schema-free JSON documents.

PATROL for Elasticsearch is a monitoring product that enables you to monitor the performance metrics of the configured Elasticsearch host. The KM monitors the performance metrics of the Elasticsearch Cluster, Nodes, JVM, Indices, and Shards. It provides ample metrics for each of these entities to fulfill all your monitoring requirements. For a list of monitor types and attributes, see Monitor types and attributes.

Elasticsearch KM facilitates filtering of indices by including or excluding them (based on name) from monitoring. It also provides failover functionality and assures high availability of performance metrics. 

For information about how to configure the KM, see Configuring Monitor Types in the Central Monitoring Administration Console.
