Class JAMonServletFilter

java.lang.Object

javax.servlet.GenericServlet

javax.servlet.http.HttpServlet

com.jamonapi.http.JAMonServletFilter

All Implemented Interfaces:

Serializable, javax.servlet.Filter, javax.servlet.Servlet, javax.servlet.ServletConfig

public class JAMonServletFilter
extends javax.servlet.http.HttpServlet
implements javax.servlet.Filter

Note this servlet filter is more functional than com.jamonapi.JAMonFilter, but either can be used. This is a wrapper class for the true monitoring class of HttpMonFactory.

Method Detail

doFilter

public void doFilter(javax.servlet.ServletRequest request,
                     javax.servlet.ServletResponse response,
                     javax.servlet.FilterChain filterChain)
              throws IOException,
                     javax.servlet.ServletException

Servlet filter method that does the monitoring

Specified by:

doFilter in interface javax.servlet.Filter

Throws:

IOException

javax.servlet.ServletException

setSummaryLabels

public void setSummaryLabels(String jamonSummaryLabels)

getSummaryLabels

public String getSummaryLabels()

addSummaryLabel

public void addSummaryLabel(String jamonSummaryLabel)

getIgnoreHttpParams

public boolean getIgnoreHttpParams()

Containers (tomcat/jetty etc) put jessionid (and other params) as part of what is returned by HttpServletRequest.getRequestURI, and HttpServletRequest.getRequestURL. This can make many pages not unique enough to benefit from jamon, so by default this part of the url is removed from the monitoring label. Example this: /myapp/mypage.jsp;jsessionid=320sljsdofou becomes this in the jamon label: /myapp/mypage.jsp getIgnoreHttpParams() - return if this is enabled or disabled (true means the params will be removed/ignored. This is the default behaviour) setIgnoreHttpParams(boolean httpIgnoreParams) - set whether it is enabled or disabled (true means the params will be removed/ignored. This is the default behaviour)

setIgnoreHttpParams

public void setIgnoreHttpParams(boolean ignoreHttpParams)

Containers (tomcat/jetty etc) put jessionid (and other params) as part of what is returned by HttpServletRequest.getRequestURI, and HttpServletRequest.getRequestURL. This can make many pages not unique enough to benefit from jamon, so by default this part of the url is removed from the monitoring label. Example this: /myapp/mypage.jsp;jsessionid=320sljsdofou becomes this in the jamon label: /myapp/mypage.jsp getIgnoreHttpParams() - return if this is enabled or disabled (true means the params will be removed/ignored. This is the default behaviour) setIgnoreHttpParams(boolean httpIgnoreParams) - set whether it is enabled or disabled (true means the params will be removed/ignored. This is the default behaviour)

setEnabled

public void setEnabled(boolean enable)

Enable/disable monitoring. Would be better to name them enable and isEnabled, but as far as I could tell tomcat can only initialize getter and setter methods.

getSize

public int getSize()

getEnabled

public boolean getEnabled()

setSize

public void setSize(int size)

Set maximum number of rows that can be in jamon before no more records are added. This will prevent jamon from growing unbounded

init

public void init(javax.servlet.FilterConfig arg0)
          throws javax.servlet.ServletException

Specified by:

init in interface javax.servlet.Filter

Throws:

javax.servlet.ServletException
