Subject [users@httpd] Query regarding the logging in Apache Web Server
Date Wed, 05 Feb 2003 11:00:24 GMT

In my module, I'm trying to log a message at the debug level. Bit it is not getting logged,
in spite of setting the LogLevel to debug within httpd.conf file.

The message that I was trying to log does not have server_rec pointer. Instead, this
parameter is passed as NULL. 

        ap_log_error(APLOG_MARK, APLOGDEBUG|APLOG_NOERRORNO, NULL, "some message");

If I pass the actual server_rec pointer, it logs the message at the debug level. I'm using
1.3.27 version.

I have looked at the apache sources and the logic used for logging is as follows:

static void log_error_core(const char *file, int line, int level,
                           const server_rec *s, const request_rec *r,
                           const char *fmt, va_list args)
    char errstr[MAX_STRING_LEN];
    size_t len;
    int save_errno = errno;
    FILE *logf;

    if (s == NULL) {
         * If we are doing stderr logging (startup), don't log messages that are
         * above the default server log level unless it is a startup/shutdown
         * notice
        if (((level & APLOG_LEVELMASK) != APLOG_NOTICE) &&
            ((level & APLOG_LEVELMASK) > DEFAULT_LOGLEVEL)) 

        logf = stderr;
    else if (s->error_log) {


Since the default log level is APLOG_WARN, debug level messages would never get logged if
server_rec is NULL. 

Is there a way to change the default level(from my module) ? Am I missing any other configuration
which would log the debug messages ?

Thanks in advance,
