Hi Tullio, well I am biased of course, but there are multiple. First, profiles are never used in production, MoSKito is aimed for production use. Not test lab, not dev machine, production, hardcore on all servers you've got. Than MoSKito also offers analysis tools, thresholds, alerts, charts etc. Finally MoSKito allows you to integrate business data into monitoring, things like registration count, checkout, gender of user, and so on...
'standard profiler' - is something designed to be used in the development environment. moskito is an apm tool. hope that helps regards Leon On Mon, Oct 3, 2016 at 4:21 PM, Tullio Bettinazzi <tullio0...@live.it> wrote: > Please help me to understand diffrences beween Moskito and standard > profilers. > > Tks > > Tullio > > > ________________________________ > Da: Leon Rosenberg <rosenberg.l...@gmail.com> > Inviato: lunedì 3 ottobre 2016 14.29 > A: Tomcat Users List > Oggetto: Re: Strange wait time in my application - Tomcat 7.0.67 > > Hi Tullio, > > you could download and integrate MoSKito -> http://www.moskito.org.
