Smokeping: smokeinfo – saving loading time
Whenever you run: smokeinfo /etc/smokeping/config , smokeping will load a lot of all configurations into memory, this takes a lot of time. Since we don’t change our configuration often, so why don’t we cache the configuration to a file and smokeping will just load it from a file. The script below is a modified version, it save about 3s loading time – i have about 7000 hosts to monitor , 3s is not a bad number. There are other things we can save time.
