server-metrics 0.5.2

• Remove Sigar requirement for JvmMonitor

server-metrics 0.5.0

• Require Java 8
• Add a new com.metamx.metrics.CpuAcctDeltaMonitor which will calculate consumed CPU as per the cpuacct cgroup.

0.3.0

Backwards incompatible changes:

1. jvm/gc/time metric is not emitted by JvmMonitor anymore, jvm/gc/cpu is added instead, it reports CPU time spend in GC (all GC generations), in nanoseconds.
2. jvm/gc/count metric emitted by JvmMonitor is changed, it emits semantically different numbers than before. Now it emits the numbers of collections in both young and old generations (identified by gcGen=young/old dimension).
