Detailed Description

Collect status information and log heartbeat messages.

This module is responsible for implementing the heartbeat log messages, which periodically inform users and operators about basic facts to do with their Tor instance. The log_heartbeat() function, invoked from main.c, is the principle entry point. It collects data from elsewhere in Tor, and logs it in a human-readable format.

Function Documentation

◆ bytes_to_usage()

STATIC char* bytes_to_usage ( uint64_t  bytes)

Take bytes and returns a newly allocated human-readable usage string.

Definition at line 79 of file status.c.

Referenced by log_heartbeat().

◆ count_circuits()

STATIC int count_circuits ( void  )

Return the total number of circuits.

Definition at line 44 of file status.c.

Referenced by log_heartbeat().

◆ log_heartbeat()

int log_heartbeat ( time_t  now)

Log a "heartbeat" message describing Tor's status and history so that the user can know that there is indeed a running Tor. Return 0 on success and -1 on failure.

Now, if we are an HS service, log some stats about our usage

Definition at line 155 of file status.c.

◆ log_onion_service_stats()

static void log_onion_service_stats ( void  )
static

Log some usage info about our onion service(s).

Definition at line 98 of file status.c.

◆ note_connection()

void note_connection ( bool  inbound,
int  family 
)

Note that a connection has arrived or has been made, for use in the heartbeat message.

Definition at line 134 of file status.c.

◆ secs_to_uptime()

STATIC char* secs_to_uptime ( long  secs)

Take seconds secs and return a newly allocated human-readable uptime string.

Definition at line 52 of file status.c.
