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.

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.

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

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

* 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.

The following configuration is now possible
## CompressionCodec represents the various compression codecs
recognized by Kafka in messages.
## "none" : No compression
## "gzip" : Gzip compression
## "snappy" : Snappy compression
# compression_codec = "none"
## RequiredAcks is used in Produce Requests to tell the broker how
many replica acknowledgements it must see before responding
## "none" : the producer never waits for an acknowledgement from the
broker. This option provides the lowest latency but the weakest
durability guarantees (some data will be lost when a server fails).
## "leader" : the producer gets an acknowledgement after the leader
replica has received the data. This option provides better durability
as the client waits until the server acknowledges the request as
successful (only messages that were written to the now-dead leader but
not yet replicated will be lost).
## "leader_and_replicas" : the producer gets an acknowledgement after
all in-sync replicas have received the data. This option provides the
best durability, we guarantee that no messages will be lost as long as
at least one in sync replica remains.
# required_acks = "leader_and_replicas"
## The total number of times to retry sending a message
# max_retry = "3"
if i understand the prometheus data model correctly, the current output
for this plugin is unusable
prometheus only accepts a single value per measurement. prior to this change, the range loop
causes a measurement to end up w/ a random value
for instance:
net,dc=sjc1,grp_dashboard=1,grp_home=1,grp_hwy_fetcher=1,grp_web_admin=1,host=sjc1-b4-8,hw=app,interface=docker0,state=live
bytes_recv=477596i,bytes_sent=152963303i,drop_in=0i,drop_out=0i,err_in=0i,err_out=0i,packets_recv=7231i,packets_sent=11460i
1457121990003778992
this 'net' measurent would have all it's tags copied to prometheus
labels, but any of 152963303, or 0, or 7231 as a value for
'net' depending on which field is last in the map iteration
this change expands the fields into new measurements by appending
the field name to the influxdb measurement name.
ie, the above example results with 'net' dropped and new measurements
to take it's place:
net_bytes_recv
net_bytes_sent
net_drop_in
net_err_in
net_packets_recv
net_packets_sent
i hope this can be merged, i love telegraf's composability of tags and
filtering
This plugin is intended to add an extended support of Postgresql
compared to the legacy postgres plugin.
Basically, the plugin don’t have any metrics defined and it’s up to the
user to define it in the telegraph.conf (as a toml structure).
Each query can have it’s specific tags, and can be written specifically
using a where clause in order to eventually filter per database name.
To be more generic, a minimum postgresql version has been defined per
query in case you have 2 different version of Postgresql running on the
same host.

added a plugin option zookeeper_chroot to set up the kafka endpoint in zookeeper, which may not be / (default).
This chroot is then configured in the consumergroup config.Zookeeper.Chroot
This is workaround the fact that this plugins does not handle the urls like "zookeeper_server:port/chroot"
As the peers are stored in an array, it makes no sens to have them beeing URL. Peers should all be members of the same cluster, so they all have the same chroot.

Also modifying the internal UDP listener/parser code to make it able to
handle higher load. The udp listener will no longer do any parsing or

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 under the "memstats" key but does not follow the format
and so is not consumed in this plugin.
