Advanced Options

This section describes additional options you may want to use for configuring, once you are comfortable using F5 BIG-IP Telemetry Streaming.

Parameter Options Description/Notes
enable false, true, string This value is used to disable any object in a declaration.
trace false, true, string This value is useful during debug of Telemetry Streaming because it dumps intermediate data to a file. This value can be applied to the Poller, Listener, and Consumer classes. The option false disables the tracer. The option true enables the tracer and dumps the data in /var/tmp/telemetry in a file named DEFAULT_LOCATION/OBJ_TYPE.OBJ_NAME. The option string sets a custom path to the file.
match string, pattern (regex) This value applies to the Telemetry_Listener class and provides a string or pattern (regex) which will result in events being dropped that do not match the value of a defined set of keys in the event. Defined keys: virtual_name, policy_name, Access_Profile, context_name
enableHostConnectivityCheck true, false This value applies to the Telemetry_Consumer and Telmetry_System class. If set to true, Telemetry Streaming will check if it can reach the host and return a fail if it cannot reach the host.
allowSelfSignedCert true, false This value applies to the Telemetry_Consumer and Telemetry_System class, as well as the Telemetry_iHealth_Poller proxy object. If set to true, allows you to use self-signed certificates.

Pointer Syntax

In certain use cases, such as configuring the generic http consumer with secrets, you may need to reference objects in other parts of the configuration. To reference other objects, Telemetry Streaming uses JSON pointers with syntax derived primarily from Application Services 3.

  • RFC 6901 compliant, with some enhancements to account for scenarios not outlined in the RFC
  • Pointer types:
    • Absolute pointer: =/Shared/secretPath
    • Relative pointer: =passphrase
    • Relative (nearest class) pointer: =@/passphrase
  • Pointer formats (determined by leading character):
    • Resolve value: =
    • Resolve value and base64 decode: +
    • Resolve value and replace property with object (no stringify): >
