I find the manager app useful in this respect. As long as your application invalidates sessions correctly the number of sessions here will be more or less the number of users, allowing for users just closing their window etc and therefore not giving the application a chance to invalidate its session.
Also within the manager app you can click on the server status and this can give you some indication of the number of active connections by the number of active threads. Each thread is detailed here. Check it out and see if it meets your needs. When you restart a tomcat the cluster performs a full synchronisation so most users may not even notice, particularly as they should get shifted over the other member of the cluster when the first goes down. Ta Matt -----Original Message----- From: MITCHELL TEIXEIRA [mailto:[EMAIL PROTECTED] Sent: 05 October 2004 23:15 To: '[EMAIL PROTECTED]' Subject: Measuring current connections, other metrics I'm hoping this is an easily answered question - is there a way with some simple Java or JSP code, or with a pre-built application to tell how many concurrent connections are going on my Tomcat instance? I'm running Tomcat 5.0.19 on Windows2000. I looked at JMeter, but that seems to be a test utility rather than a server management utility. What I'd like to see is something similar to the Windows Performance Monitor. Real-time updates every second or so. THat way when I need to restart Tomcat, I can tell how many peeved users there will be on the next click! :-) Thanks for any help MitchellT --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
