Allocating a port by IPC Broker

IPC Broker allocates the port for itself using a value in the [port] setting. If you want IPC Broker to always allocate a specific port to a sidecar, configure the following setting in the [ipc_broker] stanza in the server.conf file:

<splunkd_helper_process_name>:<service_name>:address = <value>

where:

• splunkd_helper_process_name is the process name of the sidecar. For process names of sidecars, see the Process name column in the No Content found for /db/organizations/splunk/repositories/splunk-10_4/content/documents/Platform/Shared/Splunk_Sidecars/Sidecarconfigurationsettings/Sidecarconfigurationsettings.dita table.

• service_name is the name of a service exposed by a sidecar. Each sidecar can have any number of services. Each service has to have a unique name. IPC broker allocates a specific port to each service.

• value is the IPC address, in this case a TCP/IP network port, that the sidecar service uses to serve incoming requests. The valid port range is from 1024 to 65535.

If this setting is not configured, then IPC Broker assigns a random available port to the sidecar.

In this example:

• IPC Broker is allocated the port 8194 using the port setting.

• Storage is allocated the ports 5432, 5433, 5434, 8008, 6432, 5435, 2380, and 2379 using the <splunkd_helper_process_name>:<service_name>:address settings.
