#### Source
```puppet
::fluentd::source { 'test':
priority => 10,
config => {
'type' => 'tail',
'format' => 'json',
'path' => '/var/log/test-application/*.json',
'parse' => {
'type' => 'regexp',
'expression' => '^(?<name>[^ ]*) (?<user>[^ ]*) (?<age>\d*)$'
},
'storage'=> {
'type' => 'local',
'path' => 'test.pos'
},
'tag' => 'application.test',
'parse' => {
'message_format' => 'auto'
}
}
}
```
**creates:**
```
/etc/td-agent/conf.d/10-source-test.conf
<source>
type tail
format json
path /var/log/test-application/*.json
<parse>
type regexp
expression ^(?<name>[^ ]*) (?<user>[^ ]*) (?<age>\d*)$
</parse>
<storage>
type local
path test.pos
</storage>
tag application.test
<parse>
message_format auto
</parse>
</source>
```
#### Filter
```puppet
::fluentd::filter { 'test':
priority => 20,
pattern => '*.test',
config => {
'type' => 'record_transformer',
'record' => {
'hostname' => '${hostname}'
}
}
}
```
**creates:**
```
/etc/td-agent/conf.d/20-filter-test.conf
<filter *.test>
type record_transformer
<record>
hostname ${hostname}
</record>
</filter>
```
#### Match
```puppet
::fluentd::match { 'test':
priority => 30,
pattern => '*.test',
config => {
'flush_interval' => '30s',
'type' => 'secure_forward',
'secure' => 'yes',
'shared_key' => 'my_shared_key',
'self_hostname' => 'instance.test.com',
'ca_cert_path' => '/path/to/ca.cert',
'server' => [{
'host' => 'test.server.com',
}]
}
}
```
**creates:**
```
/etc/td-agent/conf.d/30-match-test.conf
<match *.test>
flush_interval 30s
type secure_forward
secure yes
shared_key my_shared_key
self_hostname instance.test.com
ca_cert_path /path/to/ca.cert
<server>
host test.server.com
</server>
</match>
```
#### Match with buffer and chunk_keys
buffer_chunk_keys will not be included in the template. They will be filtered and only be used as a "pattern" for the buffer section.
```
::fluentd::match { 'test':
priority => 98,
pattern => 'test.**',
config => {
type => 'file',
path => '/var/log/td-agent/test/${host}',
append => true,
buffer_chunk_keys => 'host',
buffer => {
type => file,
path => /var/log/td-agent/test/buffer/,
flush_mode => immediate,
},
},
}
```
**creates:**
```
<match test.**>
type file
path /var/log/td-agent/test/${host}
append true
<buffer host>
type file
path /var/log/td-agent/test/buffer/
flush_mode immediate
</buffer>
</match>
```
#### Match Store
```puppet
::fluentd::match { 'test':
priority => 30,
pattern => '*.test',
config => {
'type' => 'copy',
'store' => [
{
'type' => 'elasticsearch',
'logstashformat' => true,
'hosts' => '172.20.10.17:9200',
'flush_interval' => '30s',
},
{
'type' => 'file',
'path' => '/tmp/td-agent-debug-${host}.log',
'buffer_chunk_keys' => 'host',
'buffer' => [{
'@type' => 'file',
path => '/var/log/td-agent/buffer/',
flush_mode => 'immediate',
}]
}
]
}
}
```
**creates:**
```
/etc/td-agent/conf.d/30-match-test.conf
<match *.test>
type copy
<store>
type elasticsearch
logstash_format true
hosts 172.20.10.17:9200
flush_interval 30s
</store>
<store>
type file
path /tmp/td-agent-debug-${host}.log
<buffer host>
@type file
path /var/log/td-agent/buffer/
flush_mode immediate
</store>
</match>
```
### Plugin Installation
This module gives you the possibility to install plugins as gem or files.
**gem installation**
```puppet
::fluentd::plugin { 'fluent-plugin-elasticsearch':
type => 'gem',
ensure => '0.1.3'
}
```
**file installation**
```puppet
::fluentd::plugin { 'fluent-plugin-elasticsearch':
type => 'file',
source => 'puppet:///path/to/plugin'
}
```
### Requirements
Modules:
* puppetlabs/apt >= 4.0.0
## Limitations
This module has been built on and tested against Puppet 4.6 and higher.
The module has been tested on:
* Ubuntu 16.04
Testing on other platforms has been light and cannot be guaranteed.
## Development
### Running the test suite
To run the tests install the ruby dependencies with `bundler` and execute
`rake`:
```
bundle install --path vendor/bundle
bundle exec rake spec
bundle exec rake lint
bundle exec rake beaker BEAKER_set=ubuntu-server-1404-x64
bundle exec rake beaker BEAKER_set=ubuntu-server-1604-x64
bundle exec rake beaker BEAKER_set=debian-60-x64
bundle exec rake beaker BEAKER_set=debian-78-x64
bundle exec rake beaker BEAKER_set=debian-82-x64
bundle exec rake beaker BEAKER_set=centos-66-x64
bundle exec rake beaker BEAKER_set=centos-70-x64
```
