fluent-plugin-influxdb is a buffered output plugin for fluentd and influxDB.
If you are using fluentd as a collector and want to organize your time-series data in influxDB, this is your right choice!
This version uses influxdb-ruby version 0.2.0 which no longer supports InfluxDB version 0.8 (which is also deprecated). If you are using InfluxDB version 0.8 please specify version 0.1.8 of this plugin.
|>= 1.0.0||>= v0.14.0||>= 2.1|
|< 1.0.0||>= v0.12.0||>= 1.9|
$ fluent-gem install fluent-plugin-influxdb -v "~> 0.3" --no-document # for fluentd v0.12 or later $ fluent-gem install fluent-plugin-influxdb --no-document # for fluentd v0.14 or later
Ruby 2.0 or earlier
influxdb gem requires
cause gem in Ruby 2.0 or earlier. If you want to use
fluent-plugin-influxdb with Ruby 2.0 or earlier,
you should install
cause gem before install
We don't recommend to use Ruby 2.0 or earlier version because these are EOL. If you don't have a problem, use ruby 2.1 or later in production.
Just like other regular output plugins, Use type
influxdb in your fluentd configuration under
host: The IP or domain of influxDB, separate with comma, default to "localhost"
port: The HTTP port of influxDB, default to 8086
dbname: The database name of influxDB, default to "fluentd". you should create the database and grant permissions first
measurement: The measurement/serise for record insertion. The default is nil.
user: The DB user of influxDB, should be created manually, default to "root"
password: The password of the user, default to "root"
retry: The finite number of retry times. default is infinite
use_ssl: Use SSL when connecting to influxDB. default to false
verify_ssl: Enable/Disable SSL Certs verification when connecting to influxDB via SSL. default to true
time_key: Use value of this tag if it exists in event instead of event timestamp
time_precision: The time precision of timestamp. default to "s". should specify either hour (h), minutes (m), second (s), millisecond (ms), microsecond (u), or nanosecond (ns)
auto_tags: Enable/Disable auto-tagging behaviour which makes strings tags.
tag_keys: The names of the keys to use as influxDB tags.
sequence_tag: The name of the tag whose value is incremented for the consecutive simultaneous events and reset to zero for a new event with the different timestamp
default_retention_policy: The retention policy applied by default. influxdb >= 0.2.3 is required to use this functionality.
retention_policy_key: The name of the key in the record whose value specifies the retention policy. The default retention policy will be applied if no such key exists. influxdb >= 0.2.3 is required to use this functionality.
Fluentd Tag and InfluxDB Series
influxdb plugin uses Fluentd event tag for InfluxDB series.
So if you have events with
app.event, influxdb plugin inserts events into
app.event series in InfluxDB.
If you set
measurement parameter, use its value instead of event tag.
<match mylog.*> @type influxdb host localhost port 8086 dbname test user testuser password mypwd use_ssl false time_precision s tag_keys ["key1", "key2"] sequence_tag _seq </match>
Cache and multiprocess
fluentd-plugin-influxdb is a buffered output plugin. So additional buffer configuration would be (with default values):
<buffer> @type memory chunk_limit_size 524288 # 512 * 1024 chunk_limit_records 1024 flush_interval 60 retry_limit 17 retry_wait 1.0 num_threads 1 </buffer>
