This page describes adding a Kafka Connect Cluster to Lenses.
Lenses integrates with Kafka Connect Clusters to manage connectors.
For documentation about the available Lenses Apache 2.0 Connectors, see the Stream Reactor documentation.
See for automating connections.
Consider if you have a high number of connectors.
To add a connection, go to Admin->Connections->New Connection->Kafka Connect.
Provide a name for the Connect cluster
Add a comma-separated list of the workers in the Connector cluster, including ports
Optionally enable Basic Auth and set the username and password
Optionally enable SSL and upload the key-store file
If you have developed your own Connector or are using not using a Lenses connector you can still display the connector instances in the topology. To do this Lenses needs to know the configuration option of the Connector that defines which topic the Connector reads from or writes to. This is set in the connectors.info parameter in the lenses.conf file.
Optionally upload a trust store
Optionally enable the collection of JMX metrics (Simple or Jolokia with SSL and Basic auth support)
connectors.info = [
{
class.name = "The connector full classpath"
name = "The name which will be presented in the UI"
instance = "Details about the instance. Contains the connector configuration field which holds the information. If a database is involved it would be the DB connection details, if it is a file it would be the file path, etc"
sink = true
extractor.class = "The full classpath for the implementation knowing how to extract the Kafka topics involved. This is only required for a Source"
icon = "file.png"
description = "A description for the connector"
author = "The connector author"
}
