Piotr Popieluch 601dc99606 Align aggregator period with internal ticker to avoid skipping metrics (#3693)
By the time the aggregator.run() was called about 600ms already passed since setting now which was skewing up the aggregation intervals and skipping metrics.

Daniel Nelson 573bd4aa32 Start first aggregator period at startup time (#3050)
Fixes issue where metrics collected immediately after startup would not
be aggregated.

Daniel Nelson b165ce4cd5 Prevent possible deadlock when using aggregators (#3016)
Looping the metrics back through the same channel could result in a
deadlock, by using a new channel and locking the processor we can ensure
that all stages can make continual progress.

Run scheduled flushes in background
doing this unblocks incoming metrics while waiting for a flush to take
place.

we have to create a semaphore so that we can
'skip' flushes that try to run while a flush is already running.

Cameron Sparr fead80844e Refactor handling of MinMax functionality into RunningAggregator
allows for easier addition of a sliding window at a later time.

Also makes `period` be a generic argument for all aggregator plugins.

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.

Cameron Sparr bfdd665435 Copy metrics for each configured output
This is for better thread-safety when running with multiple outputs,
which can cause very odd panics at very high loads

primarily this is to address #1432

Cameron Sparr d7efb7a71d Add precision rounding to accumulator
Adding precision rounding to the accumulator. This means that now every
input metric will get rounded at collection, rather than at write (and
only for the influxdb output).

This feature is disabled for service inputs, because service inputs
should be in control of their own timestamps & precisions.

Cameron Sparr 892abec025 Refactor collection_jitter and flush_jitter
use a common function between collection_jitter and flush_jitter. which
creates the same behavior between the two options.

going forward, both jitters will be random sleeps that get re-evaluated
at runtime for every interval (previously only collection_jitter did
this)

also fixes behavior so that both jitters will exit in the event of a
process exit.

Cameron Sparr c44ecf54a5 Utilize timeout in net_response plugin.
Also changing the net_response and http_response plugins to only accept
duration strings for their timeout parameters. This is a breaking config
file change.

Cameron Sparr 4f5d5926d9 Set a timeout for calls to input.Gather
Changing the internal behavior around running plugins. Each plugin
will now have it's own goroutine with it's own ticker. This means that a
hung plugin will not block any other plugins. When a plugin is hung, we
will log an error message every interval, letting users know which
plugin is hung.

Currently the input interface does not have any methods for killing a
running Gather call, so there is nothing we can do but log an "ERROR"
and move on. This will give some visibility into the plugin that is
acting up.

Cameron Sparr ee468be696 Flush based on buffer size rather than time
this includes:
- Add Accumulator to the Start() function of service inputs
- For message consumer plugins, use the Accumulator to constantly add
  metrics and make Gather a dummy function
- rework unit tests to match this new behavior.
- make "flush_buffer_when_full" a config option that defaults to true

Cameron Sparr 9c0d14bb60 Create public models for telegraf metrics, accumlator, plugins
This will basically make the root directory a place for storing the
major telegraf interfaces, which will make telegraf's godoc looks quite
a bit nicer. And make it easier for contributors to lookup the few data
types that they actually care about.
