Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?

My App has tomcat jdbc connection pool( 
https://people.apache.org/~fhanik/jdbc-pool/jdbc-pool.html ) deployed over 
tomcat 7 .I am unable to view the jdbc connections and sql hits using java 
melody.

What is the expected output? What do you see instead?
Alway 0 for "active jdbc connection","Used jdbc connection" and 0 sql hits.

What version of the product are you using? On what application server, JDK,
operating system?
OS:     Ubuntu
Java:   OpenJDK Runtime Environment, 1.7.0_25-b30
JVM:    OpenJDK 64-Bit Server VM, 23.7-b01, mixed mode
App server: Tomcat 7.0
Java Melody: 1.49

Please provide any additional information below.

My web.xml config:
<filter>
        <filter-name>monitoring</filter-name>
        <filter-class>net.bull.javamelody.MonitoringFilter</filter-class>

    </filter>
    <filter-mapping>
        <filter-name>monitoring</filter-name>
           <url-pattern>/*</url-pattern>
    </filter-mapping>
    <listener>
        <listener-class>net.bull.javamelody.SessionListener</listener-class>
    </listener> 

My context.xml:
<Resource type="javax.sql.DataSource" 
       name="jdbc/TESTDB" 
       factory="org.apache.tomcat.jdbc.pool.DataSourceFactory" 
       driverClassName="com.mysql.jdbc.Driver" 
       url="jdbc:mysql://localhost:3306/TESTDB"
       username="XXX" 
       password="XXX" 
       initialSize="5" 
       maxActive="20" 
       maxIdle="2" 
       minIdle="1" 
       testOnBorrow="true" 
       validationQuery="select 1 from dual" 
       commitOnReturn="true" 
       alternateUsernameAllowed="true"
       /> 
Any help would be appriciated.

Are you able to give the sources of a simple project, using Maven if possible, 
to reproduce the issue?

After deploying the java melody jars,I am still viewing active jdbc and used 
jdbc connection values as 0 eventhough total pool size is dipicting properly.I 
have reduced the data collection time by setting:
javamelody.resolution-seconds=1 in my catalina.properties.

I am able to see sql statistics and sql hits per minute(just a single value for 
a whole day).

Please have a look over the snapshots attached and provide your inputs.

OK, a single SQL value for a whole day.
This does not seem like a really used app anyway.
Are you able to give the sources of a simple project, using Maven if possible, 
to reproduce the issue?
Or can we close this?
Thanks

No response and no way to reproduce the issue. So resolving the issue as 
invalid/incomplete.
