DataStax Agent configuration

The address.yaml configuration file 

The address.yaml file is located in /var/lib/datastax-agent/conf on package installations, and in <install location>/conf on tarball installations. It contains configuration options for the DataStax Agent.

Options 

stomp_interface

Reachable IP address of the opscenterd machine. The connection made will be on stomp_port

stomp_port

The stomp_port used by opscenterd. The default setting is 61620.

local_interface

The IP used to identify the node. If broadcast_address is set in cassandra.yaml, this should be the same as that; otherwise, it is typically the same as listen_address in cassandra.yaml. A good check is to confirm that this address is the same as the address that nodetool ring outputs.

agent_rpc_interface

The IP that the agent HTTP server listens on. In a multiple region deployment, this is typically a private IP.

agent_rpc_broadcast_address

The IP that the central OpsCenter process uses to connect to the DataStax agent.

use_ssl

Whether or not to use SSL communication between the agent and opscenterd. Affects both the STOMP connection and agent HTTP server. Corresponds to [agents].use_ssl in opscenterd.conf. Setting this option to true turns turns on SSL connections. The default setting is 0.

cassandra_conf

The agent will attempt to auto-detect the location of the cassandra.yaml file via JMX, but if it cannot this needs to be set to the full path of cassandra.yaml. By default /etc/cassandra/cassandra.yaml on package installs or <install_location>/conf/cassandra.yaml on tarball installs.

cassandra_install_location

The location where Cassandra is installed for tarball installs if OpsCenter is unable to auto-detect the install location.

cassandra_log_location

The location of Cassandra's system.log file. This is only used for the diagnostics tarball, and should only be set if system.log is in a non-standard location.

Advanced options 

metrics_enabled

Whether or not to collect and store metrics for the local node. Setting this option to false turns off metrics collection. The default setting is true.

thrift_port

Port used to connect to local thrift server. The default setting is 9160. This information will be sent by opscenterd for convenience, but can be configured locally as needed.

jmx_host

Host used to connect to local JMX server. The default setting is localhost. This information will be sent by opscenterd for convenience, but can be configured locally as needed.

jmx_port

Port used to connect to local JMX server. The default setting is 7199. This information will be sent by opscenterd for convenience, but can be configured locally as needed.

api_port

Port the local HTTP server will bind to. The default setting is 61621. This option needs to be identical across all agents, and set explicitly in opscenterd.conf if changed.

runs_sudo

Sets whether the DataStax Agent will be run using sudo or not. Setting this option to false means the agent will not use sudo, and the agent user will not run using elevated privileges. Setting this option to true means the agent will run using sudo, and elevated privileges.

The default setting is true.
