I need some advice.
I need to be able to confirm and measure the Availability and performance of any application from an end users perspective.
I can snmp poll the physical box or ping it, but that doesn't inform me of the application 4 layers higher. It could have crashed and bugged out.
I could port scan and get a tcp port response from the application, I can also automate authentication which can confirm the availibity to an extent but no if it if functioning properly. Any advice or technique??
