Question

I use AppEngine to host an Eclipse update site. I would like to keep track of the number of downloads of each version over time. Searching for “.*plugins.*jar” in the AppEngine access logs gives me a rough idea but the logs only go back a couple of months.

Is there any easy library which I can use to graph my downloads? I’m sure I could roll my own but I would like to have pretty graphs and feel like this may be a problem which has already been solved.

I have implemented some code which met my requirements. I haven’t packaged it nicely but you can start by looking at these files:

• https://github.com/mchr3k/org.intrace/blob/master/intrace.appengine/src/org/gaecounter/CountDownloadsFilter.java
