This was primarily intended to consume InfluxDB-style expvars,
particularly InfluxDB's `/debug/vars` endpoint.
That endpoint follows a structure like
```json
{
"httpd::8086": {
"name": "httpd",
"tags": {
"bind": ":8086"
},
"values": {
"pointsWrittenOK": 33756,
"queryReq": 19,
"queryRespBytes": 26973,
"req": 428,
"writeReq": 205,
"writeReqBytes": 3939161
}
}
}
```
There are an arbitrary number of top-level keys in the JSON response at
the configured URLs, and this plugin will iterate through all of their
values looking for objects with keys "name", "tags", and "values"
indicating a metric to be consumed by telegraf.
Running this on current master of InfluxDB, I am able to record nearly
the same information that is normally stored in the `_internal`
database; the only measurement missing from `_internal` is `runtime`,
which is present in expvars under the "memstats" key but does not follow
the expvar format and so is not consumed in this plugin.
```

- Does not use the aerospike client, but sends the stats command
using the aerospike required format
- Queries available namespaces and gets stats for all of them
closes#300
- HTTP status or Socket status
- Collect those metric:
accepted conn:
listen queue:
max listen queue:
listen queue len:
idle processes:
active processes:
total processes:
max active processes:
max children reached:
slow requests:
- Tag metric with: `host` and `pool` name

The Kafka consumer plugin polls a specified Kafka topic and adds messages to
InfluxDB. The plugin assumes messages follow the line protocol. Consumer Group
is used to talk to the Kafka cluster so multiple instances of telegraf can read
from the same topic in parallel.
