Can we upgrade it to use Instrumented framework? Does instrumented spring framework come with the monitoring dashboard? Thanks in advance, -Sarang Hi Chris,

Instrumented Spring framework looks great for monitoring the performance of Spirng application.I am currently using Spring 2.0.7. Can we upgrade it to use Instrumented framework?

Does instrumented spring framework come with the monitoring dashboard?

Thanks in advance,

The reason you are seeing a growth in the HQ chart, is due to my test script being kicked off and slowly adding more users to the test environment. The number of bookings per second will soon level out as the number of users peak or the maximum capacity of the server is reached In this use case, the metric is being captured by the HQ agent running on the machine running Tomcat. The agent then returns the metric to the HQ management server where is it stored in the HQ database for up to two years. The HQ database is either a Oracle, MySQL or PostgreSQL install. As the metrics are stored in the HQ database, all data is maintained even if the application is taken off line. All historical data is also maintained if the application is restarted. The HQ and IQ charts show a different trend due to the time frame being displayed. As HQ can store data up to two years, I was looking for a nice chart that illustrates change in the metrics value over time.

So I guess that BookingsSavedPerSecond does not mean "Average bookings per second during the last 5 minutes", but "Total bookings since application startup divided by seconds since application startup". Is that correct? If so, what happens to the BookingsSavedPerSecond metric after the application is restarted (e.g. for maintenance)? How does it behave in a cluster of several identical applications, that are restarted one at a time? And why do the graphs from IQ show a decrease in Bookings Per Second, when the screenshots from HQ show an increase in BookingsSavedPerSecond? BTW, is there any documentation on what type of application resources are discovered by Instrumented Spring Framework?
