How can I know what does this message mean:

Jun 01 18:28:23.000 [debug] circuit_build_times_add_time(): Adding circuit build time 525

Note:

I'm using Log debug file TorMonitor in my torrc to view Tor logs.

As it says it's debug message, so normally you should ignore or disable any debugs.

For that kind of messages I don't think you can find reasonable meaning without Googling it or checking the source code (svn, git), because these messages are mainly for developers.

If you think it could be a bug, check at Tor bug tracker.

The code responsible for that specific message is:

/**
 * Add a new build time value <b>time</b> to the set of build times. Time
 * units are milliseconds.
 *
 * circuit_build_times <b>cbt</b> is a circular array, so loop around when
 * array is full.
 */
int
circuit_build_times_add_time(circuit_build_times_t *cbt, build_time_t time)
{
  if (time <= 0 || time > CBT_BUILD_TIME_MAX) {
    log_warn(LD_BUG, "Circuit build time is too large (%u)."
                      "This is probably a bug.", time);
    tor_fragile_assert();
    return -1;
  }

log_debug(LD_CIRC, "Adding circuit build time %u", time);
...

So the top comment above the function name should be already some help.


As far as I know the circuit build times checkings are mainly to protect Tor hidden services from botnet abuse.
