We wrote a simple method to return some stats. It's kinda crude, and may not be a 100% accurate, but here is what we did. Hope it helps. We used this documentation here
http://jakarta.apache.org/commons/dbcp/apidocs/org/apache/commons/dbcp/Basic DataSource.html public static void printDataSourceStats(DataSource ds,String dbname, javax.servlet.jsp.JspWriter out) throws SQLException { BasicDataSource bds = (BasicDataSource) ds; try { int bdsNumActive = bds.getNumActive(); int bdsMaxActive = bds.getMaxActive(); int bdsNumIdle = bds.getNumIdle(); long bdsMaxWait = bds.getMaxWait(); String fontcolor = ""; if (bdsNumActive <= 400) { fontcolor = "<font color=green>"; } else if (bdsNumActive > 400 && bdsNumActive <= 500) { fontcolor = "<font color=orange>"; } else { fontcolor = "<font color=red>"; } out.print("<table cellpadding='3' cellspacing='0'>"); out.print("<tr>"); out.print("<td class=v11 border_botdot borderg_r>" + dbname + " DataSource</td>"); out.print("</tr>"); out.print("<tr>"); out.print("<td height='24' class='columnhead9 border_r' align='center' alt='connections that are processing'># Active Connections</td>"); out.print("<td height='24' class='columnhead9 border_r' align='center' alt='total size of pool'>Maximum Active Connections</td>"); out.print("<td height='24' class='columnhead9 border_r' align='center' alt='connections that are idle in the pool'># of Idle Connections</td>"); out.print("<td height='24' class='columnhead9 border_r' align='center'>Maxium Wait period before timeout</td>"); out.print("</tr>"); out.print("<tr>"); out.print("<td class='v11 border_botdot borderg_r' >"+fontcolor + bdsNumActive + "</font></td>"); out.print("<td class='v11 border_botdot borderg_r'>" + bdsMaxActive + "</td>"); out.print("<td align='left' class='v11 border_botdot borderg_r'>" + bdsNumIdle + "</td>"); out.print("<td align='left' class='v11 border_botdot borderg_r'>" + bdsMaxWait + "</td>"); out.print("</tr>"); out.print("</table>"); } catch(Exception e) { e.printStackTrace(); } } -----Original Message----- From: Yannick Haudry [mailto:[EMAIL PROTECTED] Sent: Monday, February 19, 2007 2:37 PM To: Tomcat Users List Subject: Re: DBCP Logging If your datasource is not managed through your container but application driven, I guess Lambda probe (which is a great application) will not be able to give you information about it ? Is there a way to programmatically log the number of connections in use, etc ... ?
