Commons-DBCP-monitoring

=======================

Monitor what threads are using connections from the DBCP pool, and waiting for connection. Generate a nice table to understand what is happening.

Usage:

1. Replace your application's `commons-dbcp-1.4.jar` with [commons-dbcp-1.4-monitored.jar](https://github.com/nicolas-raoul/Commons-DBCP-monitoring/raw/master/commons-dbcp-1.4-monitored.jar) (rename it to pretend it is really the same JAR file)

2. Run your application, making sure the output is directed to a log file

3. When you want, generate a graph:

   1. Run: `./generate-dbcp-graph.sh `

   2. Wait while `dbcp-connected-by-thread.csv` and `dbcp-waiting-by-thread.csv` are generated.

   3. Open the CSV files with any spreadsheet program (like LibreOffice) and use conditional formatting to end up with the table below. To create the graph below, create a `SUM` column for each CSV and use your spreadsheet program's graphing feature.

Compilation:

1. Download the [Commons DBCP 1.4 source code](http://ftp.jaist.ac.jp/pub/apache//commons/dbcp/source/commons-dbcp-1.4-src.tar.gz)

2. Uncompress it.

3. Copy all files from the `patch-for-commons-dbcp-1.4-src` directory to into the uncompressed directory

4. Run Ant
