metrics_connection_reached_eof()

int metrics_connection_reached_eof

(

connection_t *

conn

)

Called when conn has gotten its socket closed.

metrics_get_output()

buf_t * metrics_get_output

(

const metrics_format_t

fmt

)

Return newly allocated buffer containing the output of all subsystems having metrics.

This is used to output the content on the MetricsPort.

Definition at line 71 of file metrics.c.

metrics_init()

void metrics_init

(

void

)

Initialize the subsystem.

Definition at line 272 of file metrics.c.

metrics_parse_ports()

int metrics_parse_ports	(	or_options_t *	options,
		smartlist_t *	ports,
		char **	err_msg_out
	)

Parse metrics ports from options. On success, add the port to the ports list and return 0. On failure, set err_msg_out to a newly allocated string describing the problem and return -1.
