This changes the current use of the InfluxDB client to instead use a
baked-in client that uses the fasthttp library.
This allows for significantly smaller allocations, the re-use of http
body buffers, and the re-use of the actual bytes of the line-protocol
metric representations.
We were having problems with telegraf talking to
carbon-relay-ng using the graphite output. When
the carbon-relay-ng server restarted the connection
the telegraf side would go into CLOSE_WAIT but telegraf
would continue to send statistics through the connection.
Reading around it seems you need to a read from the connection
and see a EOF error. We've implemented this and added a test
that replicates roughly the error we were having.
Pair: @whpearson @joshmyers
If we write a batch of points and get a "field type conflict" error
message in return, we should drop the entire batch of points because
this indicates that one or more points have a type that doesnt match the
database.
These errors will never go away on their own, and InfluxDB will
successfully write the points that dont have a conflict.

* Fix for broken librato output
These errors are delightful, but I'd rather avoid them:
```
Error parsing /etc/telegraf/telegraf.conf, line 2: field corresponding to `api_user' is not defined in `*librato.Librato'
```
* Fixed bad format from last commit
main reasons behind this:
- make adding/removing tags cheap
- make adding/removing fields cheap
- make parsing cheaper
- make parse -> decorate -> write out bytes metric flow much faster
Refactor serializer to use byte buffer
* NATS output plug-in now retries to reconnect forever after a lost connection.
* NATS input plug-in now retries to reconnect forever after a lost connection.
* Fixes#1953
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
And use them in the prometheus output plugin.
Still need to test the prometheus output plugin.
Also need to actually create typed metrics in the system plugins.

closes#1539
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.
Revert "Updated changelog"
This reverts commit 24dba5520008d876b5a8d266c34a53e8805cc5f5.
Added PR under 1.1 release.
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.
* 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
correct URL from instrumental fork to origin and put the change in the correct part of the file
* go fmt
* Split out Instrumental tests for invalid metric and value.
* Ensure nothing remains on the wire after final test.
* Force valid metric names by replacing invalid parts with underscores.
* Multiple invalid characters being joined into a single udnerscore.
* Adjust comment to what happens.
* undo split hello and auth commands, to reduce roundtrips
* Split out Instrumental tests for invalid metric and value.
* Ensure nothing remains on the wire after final test.
* Force valid metric names by replacing invalid parts with underscores.
* Multiple invalid characters being joined into a single udnerscore.
* add an entry to CHANGELOG for easy merging upstream
* go fmt variable alignment
* remove some bugfixes from changelog which now more properly are in a different section.
* remove headers and whitespace should should have been removed with the last commit
* 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
* Limit 80 char per line, change resolution to be a int in the sample
* fmt
* remove resolution, doc for template
* fmt
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'
