Eric Yang updated CHUKWA-571:
-----------------------------
Attachment: CHUKWA-571.patch
Digest metrics is parse and stored without number suffix. For example, the
total bytes received by all network card is in network:RxBytes column. Network
Loopback device is omitted from the summary number.
Full list of digest metrics:
* Averaged CPU utilization:
* cpu:combined (user+sys)
* cpu:idle
* cpu:sys
* cpu:user
Sum of network devices throughput stats at interval:
* network:RxBytes
* network:RxDropped
* network:RxErrors
* network:RxPackets
* network:TxBytes
* network:TxColisions
* network:TxErrors
* network:TxPackets
Sum of disk devices throughput stats at interval:
* disk:ReadBytes
* disk:Reads
* disk:WriteBytes
* disk:Writes
> Add digested system metrics to SystemMetrics demux parser

> For now, the system metrics demux parser are storing raw metrics. Each
> system components are measured independently. It would be nice to make a
> summary grouping for cpu, disk, network. Instead of storing cpu:combined.0
> ... cpu:combined.8, for 8 cpu cores in the system, it would be nice to have a
> average number for all cpus combined. The digested metrics are easier to
> aggregate at cluster level.
