Hi Erik, Thank for your answer, do you mean I can use check_load command to monitor CPU of my server? I'll try to use "<a href="http://check_memory.pl">check_memory.pl</a>" or "<a href="http://check_mem.pl">check_mem.pl</a>" to monitor Memory as you recommended. Again, thank you so much.

Feel free to have a look at it. For the memory test you can choose between the plugins "<a href="http://check_memory.pl" target="_blank">check_memory.pl</a>" or "<a href="http://check_mem.pl" target="_blank">check_mem.pl</a>". Feel free to choose. -- So long...
