Well, depending on what you are monitoring and what you want to accomplish: they can use SNMP to retrieve values or more extensive application specific testing, so at minimum, the impact is identical to a NetSNMP instance, and at worst, they have the impact of a additional client user of the application being tested multiplied by the number of applications running on the individual server. Don't confuse Nagios/Hobbit with the type of detail data collection that your products do -- both are more health-check monitors than "performance" monitors, although they can be used for that purpose if you know what to do with the numbers. Nagios (I'll let Rich speak to Hobbit) does both retrieving data a la SNMP, and execution of both predefined and user-supplied test scripts for applications. If what you're looking for is a "is it running, and are the applications I care about responding in a reasonable manner", then Nagios and Hobbit are plenty sufficient. >I haven't heard of > anyone running these on systems with many servers, Nagios is widely used with discrete servers.

Me either, but I also think that the vast majority of IBM field people don't understand VE enough to even know it's there, let alone how to sell it or use it. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
