well, SNMP is a proper Nagios client. <br><br>With rocommunity and firewall rules, security isn't a big deal. <br><br>I'm using SNMP to actively issue checks when passive transport get stalled. It tries to send the passive result, expecting good return code from send_nsca (and could check for cron, try to determine if server is thrashing, and so on), or, sends back to snmpget the result. <br>

Hi,<br>
<br>
If you just want to check if a host is alive, icmp is the protocol<br>
that's always been used for this purpose.<br>
<br>
I use snmp mostly for appliances, eg. Routers, firewall and switches,<br>
wherr I can't install a proper Nagios client to rely on.<br>
<br>
Ciao,<br>
<br>
