Events are written to files locally and, once file is closed, this plugin uploads it to the configured BigQuery dataset. VERY IMPORTANT: . To make good use of BigQuery, your log events should be parsed and structured. Consider using grok to parse your events into fields that can be uploaded to BQ. . You must configure your plugin so it gets events with the same structure, so the BigQuery schema suits them. In case you want to upload log events with different structures, you can utilize multiple configuration blocks, separating different log events with Logstash conditionals. More details on Logstash conditionals can be found here: http://logstash.net/docs/1.2.1/configuration#conditionals For more info on Google BigQuery, please go to: https://developers.google.com/bigquery/ In order to use this plugin, a Google service account must be used. For more information, please refer to: https://developers.google.com/storage/docs/authentication#service_accounts Recommendations: . Experiment with the settings depending on how much log data you generate, your needs to see "fresh" data, and how much data you could lose in the event of crash. For instance, if you want to see recent data in BQ quickly, you could configure the plugin to upload data every minute or so (provided you have enough log events to justify that). Note also, that if uploads are too frequent, there is no guarantee that they will be imported in the same order, so later data may be available before earlier data. . BigQuery charges for storage and for queries, depending on how much data it reads to perform a query. These are other aspects to consider when considering the date pattern which will be used to create new tables and also how to compose the queries when using BQ.

It must follow this format: :,:,... Example: path:STRING,status:INTEGER,score:FLOAT [id="plugins-{type}s-{plugin}-dataset"] ===== `dataset` * This is a required setting. * Value type is <> * There is no default value for this setting. BigQuery dataset to which these events will be added to. [id="plugins-{type}s-{plugin}-date_pattern"] ===== `date_pattern` * Value type is <> * Default value is `"%Y-%m-%dT%H:00"` Time pattern for BigQuery table, defaults to hourly tables. Must Time.strftime patterns: www.ruby-doc.org/core-2.0/Time.html#method-i-strftime [id="plugins-{type}s-{plugin}-deleter_interval_secs"] ===== `deleter_interval_secs` * Value type is <> * Default value is `60` Deleter interval when checking if upload jobs are done for file deletion. This only affects how long files are on the hard disk after the job is done. [id="plugins-{type}s-{plugin}-flush_interval_secs"] ===== `flush_interval_secs` * Value type is <> * Default value is `2` Flush interval in seconds for flushing writes to log files. 0 will flush on every message. [id="plugins-{type}s-{plugin}-ignore_unknown_values"] ===== `ignore_unknown_values` * Value type is <> * Default value is `false` Indicates if BigQuery should allow extra values that are not represented in the table schema. If true, the extra values are ignored. If false, records with extra columns are treated as bad records, and if there are too many bad records, an invalid error is returned in the job result. The default value is false. [id="plugins-{type}s-{plugin}-json_schema"] ===== `json_schema` * Value type is <> * Default value is `nil` Schema for log data, as a hash. Example: json_schema => { fields => [{ name => "timestamp" type => "TIMESTAMP" }, { name => "host" type => "STRING" }, { name => "message" type => "STRING" }] } [id="plugins-{type}s-{plugin}-key_password"] ===== `key_password` * Value type is <> * Default value is `"notasecret"` Private key password for service account private key.

Service account to access Google APIs. [id="plugins-{type}s-{plugin}-table_prefix"] ===== `table_prefix` * Value type is <> * Default value is `"logstash"` BigQuery table ID prefix to be used when creating new tables for log data. Table name will be [id="plugins-{type}s-{plugin}-table_separator"] ===== `table_separator` * Value type is <> * Default value is `"_"` BigQuery table separator to be added between the table_prefix and the date suffix.
