telegraf v0.1.9 发布，更新内容如下：
InfluxDB output config change: url is now urls, and is a list. Config files will still be backwards compatible if only url is specified.
The -test flag will now output two metric collections
Support for filtering telegraf outputs on the CLI -- Telegraf will now allow filtering of output sinks on the command-line using the -outputfilterflag, much like how the -filter flag works for plugins.
Support for filtering on config-file creation -- Telegraf now supports filtering to -sample-config command. You can now runtelegraf -sample-config -filter cpu -outputfilter influxdb to get a config file with only the cpu plugin defined, and the influxdb output defined.
Breaking Change: The CPU collection plugin has been refactored to fix some bugs and outdated dependency issues. At the same time, I also decided to fix a naming consistency issue, so cpu_percentageIdle will become cpu_usage_idle. Also, all CPU time measurements now have it indicated in their name, so cpu_idle will become cpu_time_idle. Additionally, cpu_time measurements are going to be dropped in the default config.
Breaking Change: The memory plugin has been refactored and some measurements have been renamed for consistency. Some measurements have also been removed from being outputted. They are still being collected by gopsutil, and could easily be re-added in a "verbose" mode if there is demand for it.
