Revert using fasthttp library to net/http 2017-01-25 16:42:23 -08:00
Cameron Sparr 4a5d313693
Improve the InfluxDB through-put performance
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.

Will Pearson d7a8bb2214 Fix problem with graphite talking to closed connections (#2171)
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.

influxdb output: treat field type conflicts as a successful write
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.

Kurt Mackey 2aa2c796e5 Fix for broken librato output (#2225)
* 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

Cameron Sparr db7a4b24b6 Implement telegraf's own full metric type
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

Eric 6e33a6d62f OpenTSDB HTTP output
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.

tuier e457b7a8df Source improvement for librato output (#1416)
* 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

Cameron Sparr 1c24665b29 Prometheus client & win_perf_counters char changes
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'
