Introduction to Jprofiler training

• JProfiler Training at Global Online
  Trainings provides you the best knowledge
  regarding Java Profiler. It includes many
  concepts regarding Profiling. The advanced Java
  Profiler Online Training is provided by high
  Professionals at reasonable price for the
  candidates and will provide both Java Profiler
  Online Training and also JProfiler Corporate
  Training also at flexible timings.
• Probes show you higher level information on what
  is happening in application. For example SQL
  statements that are executed and which of those
  SQL statements are slow.For example, if we have
  knowledge on JDBC, which generates some SQL
  statements and execute them. So we can test the
  JDBC probe.
• In the settings we can find out all the available
  built-in probes. It includes record events,
  annotate into call tree view.
• There are many probes that are present in the
  settings. They include JNDI Probe, JMS Probe,
  Servlets, Sockets, Files and processes probe that
  shows you processes that are launched by your
  application

Profiling Tomcat in StandAlone- Java Profiler
Training

• In order to create profiling, we first need to
  create a test project. We can create a new
  project by clicking on new project icon. This can
  be showed on screen lively during the JProfiler
  Training.
• Let us name the new project name as Petstore. We
  can find the import tab instead of creating a
  project from scratch. We can import the project
  from your IDE.
• App perfect can import projects for a most
  commonly used IDE. In the source tab, we can add
  our project source.
• We can add source folder containing Java files
  using the add folder button. Once the required
  files and folders are added, then the source tree
  will be visible.
• There we can configure the JDK and JRE that
  compiles and executes your code. We can choose
  the default JDK.

JDBC demo application in JProfiler Training 

• At first we need to go to the JE and Probes view
  and make sure that the JDBC probe is activated in
  the probe selector.
• By default probes dont record data unless you
  explicitly specify that in the profiling
  settings. So we have to start recording with that
  button right next to the probe selector.
• There we can find the Timeline view of all open
  JDBC Connections. There is nothing happening
  there, because this JDBC demo requires that we
  click on the start database activity button to
  start executing SQL statements.
• Let us do that and there we can find 5 JDBC
  connections that have been opened by this JDBC
  demo. There is heavy activity going on there, the
  statement execution, prepare the statement
  execution and the Timeline view shows you what
  these JDBC connections are doing, the connections
  tab shows you a tabular overview.
• There we can find the event count and event
  duration and events are the basis of all recorded
  probe data. So let us go to the events, there we
  can find many single SQL statements.

Monitor Test in JProfiler Training

• One thing worth mentioning is that, we need to
  add a JVM start-up trigger.
• That starts monitor recording as soon as the JVM
  is started. This is necessary because we dont
  have to manually start monitor recording and we
  can see all the events in locking history graph
  from the start-up of the JVM.
• If we observe on the screen during the JProfiler
  Training, we can look at the current locking
  graph there.
• They are red dashed lines, black lines and yellow
  lines. The red lines are used for blocking and
  the black lines are for own monitors and the
  yellow lines are for waiting. This will happen
  all for too quickly- JProfiler Training.
• We can just look at very static situations. But
  the most complex stuff happens further quickly.
  So we need to go to the locking history graph for
  a more detailed analysis.
