[mod_cluster-issues] [JBoss JIRA] (MODCLUSTER-157) SystemMemoryUsageLoadMetric returns wrong load metric

SystemMemoryUsageLoadMetric returns wrong load metric ----------------------------------------------------- Key: MODCLUSTER-157 URL: https://issues.jboss.org/browse/MODCLUSTER-157 Project: mod_cluster Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 1.0.3.GA, 1.1.0.CR2 Reporter: Masafumi Miura Assignee: Paul Ferraro Fix For: 1.0.4.GA, 1.1.0.CR3 When using SystemMemoryUsageLoadMetric, mod_cluster prioritizes dispatching requests to a machine which are using system memory higher than other machines. This loadbalancing behaviour is odd. SystemMemoryUsageLoadMetric[1] returns wrong load metric. The SystemMemoryUsageLoadMetric#getLoad() should not return "free / total". It should return "(total - free) / total" (= usage / total ) like HeapMemoryUsageLoadMetric[2]. [1] http://anonsvn.jboss.org/repos/mod_cluster/tags/1.0.3.GA/src/main/java/or...
