Nagios uses a set of plugins, which are in the nagios-plugins package, and available from the main nagios site (iirc, the plugins are also on nagios-plugins.sf.net). For network service monitoring (like telnet) there's a connect_tcp plugin which can open a tcp connection to any numbered port. Some of the common services (ssh, and http at least) have custom plugins which return whatever banner the host sends. The only way I've ever seen nagios monitor internal system states (disc usage, cpu usage etc) is via SNMP. The check_snmp plugin supports snmp 1 & 2, possibly 3 and has command-line options that can be used to specify different get and set community names from the default public/private, you could take advantage of this and use different community names from the default on your snmp devices. -- Stephen Patterson http://patter.mine.nu/ [EMAIL PROTECTED] remove SPAM to reply Linux Counter No: 142831 GPG Public key: 252B8B37 Caution: breathing may be hazardous to your health. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
