Issue #634 resolved
As a practical example, the line below previously would indicate the output (stdout) of any program on the monit webinterface. Since 5.23, the output is empty (no output / '-')
CHECK PROGRAM syslog PATH "/usr/bin/tail -n 1 /var/log/messages" TIMEOUT 2 SECONDS IF STATUS != 0 THEN ALERT
Has there been any change recently?
