in this commit:
- chunks out the http request body to avoid making very large
allocations.
- establishes a limit for the maximum http request body size that the
listener will accept.
- utilizes a pool of byte buffers to reduce GC pressure.
The MySQL DB driver has it's own DSN parsing function. Previously we
were using the url.Parse function, but this causes problems because a
valid MySQL DSN can be an invalid http URL, namely when using some
special characters in the password.
This change uses the MySQL DB driver's builtin ParseDSN function and
applies a timeout parameter natively via that.
Another benefit of this change is that we fail earlier if given an
invalid MySQL DSN.

Previously, the graphite parser would simply overwrite any template that
had an identical filter to a previous template. This included the empty
filter.
Now we will still overwrite, but first we will sort to make sure that
the most "specific" template always matches.

Map holding expected results was defined in multiple places, making test
cases a bit hard to read. This way we can change our expectations of
good results in one place and have them affect multiple test cases.
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.
closes#1786
Due to quite real problem of generating vast number of data series through
mesos tasks metrics this feature is disabled until better solution is found.
Also consolidated the translation code to obtain all info with just 1 command execution.
Also split test command mocks out to their own file for cleanliness.
The default is 0 so we hit a division by 0 error and crash. This checks
ensure we will not crash and `log` and continue to let telegraf run
Also we set default allow pending message number to 10000
* Allow numeric and non-string values for tag_keys.
According to the go documentation the JSON deserializer only produces these
base types in output:
- string
- bool
- float64
- nil
With this patch bool, float64 and nil values get converted to a string when
their field key is specified in tag_keys. Previously the field was simply
discarded.
* Updated handling of nil for passing tests.
The automated tests are less than trivial to reproduece locally for me,
so I hope CircleCI wonn't mind...
* Updated changelog entries with PR and issue links.
* separate hello and authenticate functions, force connection close at end of write cycle so we don't hold open idle connections, which has the benefit of mostly removing the chance of getting hopelessly connection lost
* update changelog, though this will need to be updated again to merge into telegraf master
* bump instrumental agent version
* fix test to deal with better better connect/reconnect logic and changed ident & auth handshake
* Update CHANGELOG.md

also remove locking around adding metrics. Instead, keep a waitgroup on
the ServeHTTP function and wait for that to finish before returning from
the Stop() function

The iptables plugin aims at monitoring bytes and packet counters

Typically the user would set a dedicated monitoring chain into a given

First version of http put working
Refactored code to separate http handling from opentsdb module. Added batching support.
Fixed tag cleaning in http output and refactored telnet output.
Removed useless struct.
Fixed current unittest and added a new one.
Added benchmark test to test json serialization. Made sure http client would reuse connection.
Ran go fmt on opentsdb sources.
Updated README file
Removed useHttp in favor of parsing host string to determine the right API to use for sending metrics. Also renamed BatchSize to HttpBatchSize to better convey that it is only used when using Http API.
Updated changelog
Fixed format issues.
Removed TagSet type to make it more explicit.
Fixed unittest after removing TagSet type.

add missing redis metrics
This makes sure that all redis metrics are present without having to use a hard-coded list of what metrics to pull in.
The existing ceph input plugin only has access to the local admin daemon socket
on the local host, and as such has access to a limited subset of data. This
extends the plugin to use CLI commands to get access to the full spread of Ceph
data. This patch collects global OSD map and IO statistics, PG state and per pool
IO and utilization statistics.

* Source improvement for librato output
Build the source from the list of tag instead of a configuration specified
single tag
Graphite Serializer:
* make buildTags public
* make sure not to use empty tags
Librato output:
* Improve Error handling for librato API base on error or debug flag
* Send Metric per Batch (max 300)
* use Graphite BuildTag function to generate source
The change is made that it should be retro compatible
Metric sample:
server=127.0.0.1 port=80 state=leader env=test
measurement.metric_name value
service_n.metric_x
Metric before with source tags set as "server":
source=127.0.0.1
test.80.127_0_0_1.leader.measurement.metric_name
test.80.127_0_0_1.leader.service_n.metric_x
Metric now:
source=test.80.127.0.0.1.leader
measurement.metric_name
service_n.metric_x
As you can see the source in the "new" version is much more precise
That way when filter (only from source) you can filter by env or any other tags
* Using template to specify which tagsusing for source, default concat all
tags
* revert change in graphite serializer
* better documentation, change default for template
* fmt
* test passing with new host as default tags
* use host tag in api integration test

this log format is likely soon going to be removed from a future
influxdb release, so we should not be recommending that users base any
of their log parsing infra on this.

1. in prometheus client, do not check for invalid characters anymore,
because we are already replacing all invalid characters with regex
anyways.
2. in win_perf_counters, sanitize field name _and_ measurement name.
Also add '%' to the list of sanitized characters, because this character
is invalid for most output plugins, and can also easily cause string
formatting issues throughout the stack.
3. All '%' will now be translated to 'Percent'

* add initial support to allow self-signed certs
When using self-signed the metrics collection will fail, this will allow
the user to specify in the input configuration file if they want to skip
certificate verification. This is functionally identical to `curl -k`
At some point this functionality should be moved to the agent as it is
already implemented identically in several different input plugins.

* Allow for TLS connections to ElasticSearch
Extremely similar implementation to the HTTP JSON module's

* Changelog update
I added Rows/Logs max size counters for tracking databases that do not have autogrowth enabled. The counters return numbers in 8KB pages since there are a few special values (such as -1 for no max size) that can't directly be multiplied by 8192 to get size in bytes.
Also added Rows/Logs size in 8KB pages for comparison from the same system table. Even though it returns the same size as sizes from sys.dm_io_virtual_file_stats which are already collected.
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.
