Created attachment 863246 [details] entropy DataSources patch +++ This bug was initially created as a clone of Bug #1065338 +++ Description of problem: collection.conf expects the "entropy" data series to have DataSources set to "entropy", but what collectd produces has it set to "value" instead. This prevents collectd-web from producing an entropy graph. Version-Release number of selected component (if applicable): collectd-web-5.4.1-1.fc20.x86_64 How reproducible: Always. Steps to Reproduce: 1. Turn on collectd "entropy" plugin. 2. Collect some data. 3. Try to graph it with collectd-web. Actual results: No graph. Expected results: A graph of system entropy over time. Additional info: The attached patch fixes the problem.
