Установлен сервер FreeBSD 8.2, на котором установлен Nagios 3.5, для мониторинга Windows 2003 RUS машин установлен клиент NSClient++ 0.4.1.90. Дак вот в Nagios на Windows машинах неправильно отображается Memory usage: total:3937,11 Mb - used: 918,50 Mb (23%) - free: 3018,62 Mb (77%). Total 4GB, а фактически физической памяти на сервере 2Gb. Откуда он берет +2GB? Как вылечить?

;# OBFUSCATED PASSWORD
;  This is the same as the password option but here you can store the password in an obfuscated manner.
;  *NOTICE* obfuscation is *NOT* the same as encryption, someone with access to this file can still figure out the

;# ENCRYPTION METHOD
;   This option determines the method by which the send_nsca client will encrypt the packets it sends

;   performance, as strong encryption methods consume more processor resources.
;   You should evaluate your security needs when choosing an encryption method.
;
; Note: The encryption method you specify here must match the decryption method the nsca daemon uses
;       (as specified in the nsca.cfg file)!!

;    0 = None    (Do NOT use this option)
