Nagios does not actively monitor hosts. Yes, it checks hosts, but it does not monitor them. What's the difference? Think of hosts as points or intersections along a road, services as being houses along the side of these roads. Nagios only monitors houses (services). If for some reason it cannot reach a house, it checks to see if there is a problem in the road (host) preventing it from getting to the house (service), and reports these findings to you.</FONT></SPAN></DIV> <DIV><SPAN class=720565120-20072006><FONT face=Arial color=#0000ff size=2></FONT></SPAN> </DIV> <DIV><SPAN class=720565120-20072006><FONT face=Arial color=#0000ff size=2>If you want Nagios to work like CA's product, that can be done as well, but you'll lose ther ability to determine where along the roadway is the problem. To do this, use check_cluster for your check-host-alive.</FONT></SPAN></DIV> <DIV><SPAN class=720565120-20072006><FONT face=Arial color=#0000ff size=2></FONT></SPAN> </DIV> <BLOCKQUOTE style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #0000ff 2px solid"> <DIV class=OutlookMessageHeader dir=ltr align=left><FONT face=Tahoma size=2>-----Original Message-----<BR><B>From:</B> Tom Tran [mailto:thoanluutran@yahoo.com]<BR><B>Sent:</B> Thursday, July 20, 2006 10:02 AM<BR><B>To:</B> nagios-users@lists.sourceforge.net<BR><B>Subject:</B> [Nagios-users] Sugguestion/Question?
