As "fails" is generally application-dependent, you will need: - An application-dependent monitoring page in your webapp. When invoked, it should test everything that you think means the application is "working" and return a known output if everything is OK. - Some suitably stable monitoring platform on which to run your monitor, which should invoke your monitoring page on each of node1 and node2 and check for the known output that everything is OK. This should *not* be "the system". "The system" can crash, run out of memory or do a myriad other things such that it has failed and will not send you an email. It should be some completely separate computer or - for the really paranoid - set of computers. Nagios, for example, will do this. See the section "Monitoring HTTP" on http://nagios.sourceforge.net/docs/3_0/monitoring-publicservices.html for details. There are other apps, Nagios is merely an example. - Regular emails or other notification that the application *is* working. If you only get emailed when the app fails, you never know whether lack of email means everything is OK, or whether something is so broken it can't even send the email to tell you. - Peter --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
