enumerator TS_LIFECYCLE_PORTS_INITIALIZED_HOOK

Called after the proxy server port data structures have been initialized but before connections are accepted on those ports. The sockets corresponding to the ports may or may not be open depending on how the traffic_server process was invoked. Other API functions that depend on server ports should be called from this hook and not TSPluginInit().

Invoked with the event TS_EVENT_LIFECYCLE_PORTS_INITIALIZED and NULL data.

enumerator TS_LIFECYCLE_PORTS_READY_HOOK

Called after enabling connections on the proxy server ports. Because Traffic Server is threaded this may or may not be called before any connections are accepted. The hook code may assume that any connection to Traffic Server started after this hook is called will be accepted by Traffic Server, making this a convenient place to signal external processes of that.

Invoked with the event TS_EVENT_LIFECYCLE_PORTS_READY and NULL data.

enumerator TS_LIFECYCLE_CACHE_READY_HOOK

Called after Traffic Server cache initialization has finished.

Invoked with the event TS_EVENT_LIFECYCLE_CACHE_READY and NULL data.

enumerator TS_LIFECYCLE_MSG_HOOK

Called when triggered by an external process, such as traffic_ctl.

Invoked with the event TS_EVENT_LIFECYCLE_MSG. The data is an instance of the TSPluginMsg. This contains a tag which is a null terminated string and a data payload. The payload cannot be assumed to be null terminated and is created by the external agent. Its internal structure and format are entirely under the control of the external agent although presumably there is an agreement between the plugin and the external where this is determined by the tag.

enumerator TS_LIFECYCLE_CLIENT_SSL_CTX_INITIALIZED_HOOK

Called after the initialization of the SSL context used by Traffic Server for outbound connections (Traffic Server as client).

enumerator TS_LIFECYCLE_SERVER_SSL_CTX_INITIALIZED_HOOK

Called after every SSL context initialization used by Traffic Server for inbound connections (Traffic Server as the server).

enumerator TS_LIFECYCLE_TASK_THREADS_READY_HOOK

Called after Traffic Server task threads have been started.

Invoked with the event TS_EVENT_LIFECYCLE_TASK_THREADS_READY and NULL data.

enumerator TS_LIFECYCLE_SHUTDOWN_HOOK

Called after Traffic Server receiving a shutdown signal, such as SIGTERM.

Invoked with the event TS_EVENT_LIFECYCLE_SHUTDOWN and NULL data.

const char *tag

The tag of the message. This is a null terminated string.

const void *data

Message data (payload). This is a raw slab of bytes - no structure is guaranteed.

size_t data_size

The number of valid bytes pointed at by TSPluginMsg.data.
