Cameron Sparr c7834209d2 Major Logging Overhaul 
in this commit:

- centralize logging output handler.
- set global Info/Debug/Error log levels based on config file or flags.
- remove per-plugin debug arg handling.
- add a I!, D!, or E! to every log message.
- add configuration option to specify where to send logs.

Telegraf plugin: procstat

Description

The procstat plugin can be used to monitor system resource usage by an individual process using their /proc data.

The plugin will tag processes by their PID and their process name.

Processes can be specified either by pid file, by executable name, by command line pattern matching, or by username (in this order or priority. Procstat plugin will use pgrep when executable name is provided to obtain the pid. Proctstas plugin will transmit IO, memory, cpu, file descriptor related measurements for every process specified. A prefix can be set to isolate individual process specific measurements.

Example:

[[inputs.procstat]]
  exe = "influxd"
  prefix = "influxd"

[[inputs.procstat]]
  pid_file = "/var/run/lxc/dnsmasq.pid"

The above configuration would result in output like:

> procstat,name="dnsmasq",pid="44979" cpu_user=0.14,cpu_system=0.07
> procstat,name="influxd",pid="34337" influxd_cpu_user=25.43,influxd_cpu_system=21.82
