A node template consists of a set of pre-defined node settings. To ensure consistency of configuration across all Data Insight server nodes, you can create templates with the required settings and apply them when configuring the servers.

Data Insight comes bundled with three standard templates which include frequently used settings to help you set up nodes for well known configurations, for example, templates for POC configuration, large Indexer, and large Collector. The standard node templates are stored in the INSTALL_DIR\conf\node_templatefolder. You cannot edit or delete the standard node templates from the console.

You can apply multiple templates when configuring a server. However, when you apply multiple templates to a node, Data Insight applies each template serially when evaluating the configuration for that node. You can also use a node template to change a single setting on all nodes. For example, if you want to change the Ping timeout setting for all nodes, you can create a template with the required timeout setting and apply to all Data Insight nodes in your environment.
