Description
editSummary: plugin to upload log events to Google Cloud Storage (GCS), rolling files based on the date pattern provided as a configuration setting. Events are written to files locally and, once file is closed, this plugin uploads it to the configured bucket.
For more info on Google Cloud Storage, please go to: https://cloud.google.com/products/cloud-storage
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
Recommendation: experiment with the settings depending on how much log data you generate, so the uploader can keep up with the generated logs. Using gzip output can be a good option to reduce network traffic when uploading the log files and in terms of storage costs as well.
USAGE: This is an example of logstash config:
output { google_cloud_storage { bucket => "my_bucket" (required) key_path => "/path/to/privatekey.p12" (required) key_password => "notasecret" (optional) service_account => "[email protected]" (required) temp_directory => "/tmp/logstash-gcs" (optional) log_file_prefix => "logstash_gcs" (optional) max_file_size_kbytes => 1024 (optional) output_format => "plain" (optional) date_pattern => "%Y-%m-%dT%H:00" (optional) flush_interval_secs => 2 (optional) gzip => false (optional) uploader_interval_secs => 60 (optional) } }
- Support logstash event variables to determine filename.
- Turn Google API code into a Plugin Mixin (like AwsConfig).
- There’s no recover method, so if logstash/plugin crashes, files may not be uploaded to GCS.
- Allow user to configure file name.
- Allow parallel uploads for heavier loads (+ connection configuration if exposed by Ruby API client)

Common options
editThese configuration options are supported by all output plugins:
codec
edit- Value type is codec
-
Default value is
"plain"
The codec used for output data. Output codecs are a convenient method for encoding your data before it leaves the output without needing a separate filter in your Logstash pipeline.
enable_metric
edit- Value type is boolean
-
Default value is
true
Disable or enable metric logging for this specific plugin instance. By default we record all the metrics we can, but you can disable metrics collection for a specific plugin.
id
edit- Value type is string
- There is no default value for this setting.
Add a unique ID
to the plugin configuration. If no ID is specified, Logstash will generate one.
It is strongly recommended to set this ID in your configuration. This is particularly useful
when you have two or more plugins of the same type. For example, if you have 2 google_cloud_storage outputs.
Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.
output { google_cloud_storage { id => "my_plugin_id" } }
