To those curious; switching between different facilities is NOT an issue. There is no apparent memory overhead (nor slowdown) by calling openlog multiple(12 * 10000) times.
Shown by this example:
<?php
$facilities = array(
LOG_AUTH,
LOG_AUTHPRIV,
LOG_CRON,
LOG_DAEMON,
LOG_KERN,
LOG_LOCAL0,
LOG_LPR,
LOG_MAIL,
LOG_NEWS,
LOG_SYSLOG,
LOG_USER,
LOG_UUCP,
);
for ($i = 0; $i < 10000; $i++) {
foreach ($facilities as $facility) {
openlog('test', LOG_PID, $facility);
syslog(LOG_ERR, "This is a test: " . memory_get_usage(true));
}
}
?>openlog
(PHP 4, PHP 5, PHP 7, PHP 8)
