This extension works only with the standalone machine agent.
Apache CouchDB, commonly referred to as CouchDB, is an open source database that focuses on ease of use and on being "a database that completely embraces the web." It is a NoSQL database that uses JSON to store data, uses JavaScript as its query language using MapReduce, and uses HTTP for an API. The CouchDB monitoring extension gathers metrics for the specified hosts that have couchDB installed.
<MachineAgent_Dir>/monitors/CouchDBMonitor The metricPrefix of the extension has to be configured as specified here. Please make sure that the right metricPrefix is chosen based on your machine agent deployment, otherwise this could lead to metrics not being visible in the controller.The host id, port, username, and password need to be configured for each host. Here is a sample configuration for one host:
<Host id="localhost" port="5984" username="username" password="password"/>
