Google Cloud moduleedit

This is a module for Google Cloud logs. It supports reading VPC flow and firewall logs that have been exported from Stackdriver to a Google Pub/Sub topic sink.

When you run the module, it performs a few tasks under the hood:

  • Sets the default paths to the log files (but don’t worry, you can override the defaults)
  • Makes sure each multiline log event gets sent as a single event
  • Uses ingest node to parse and process the log lines, shaping the data into a structure suitable for visualizing in Kibana

Configure the moduleedit

You can further refine the behavior of the googlecloud module by specifying variable settings in the modules.d/googlecloud.yml file, or overriding settings at the command line.

Variable settingsedit

Each fileset has separate variable settings for configuring the behavior of the module. If you don’t specify variable settings, the googlecloud module uses the defaults.

For more information, see Configure variable settings. Also see Override input settings.

When you specify a setting at the command line, remember to prefix the setting with the module name, for example, googlecloud.vpcflow.var.paths instead of vpcflow.var.paths.

vpcflow fileset settingsedit

Example config:

- module: googleclcoud
  vpcflow:
    enabled: true
    var.project_id: my-gcp-project-id
    var.topic: googlecloud-vpc-flowlogs
    var.subscription_name: filebeat-googlecloud-vpc-flowlogs-sub
    var.credentials_file: ${path.config}/gcp-service-account-xyz.json
    var.keep_original_message: false
var.paths
An array of glob-based paths that specify where to look for the log files. All patterns supported by Go Glob are also supported here. For example, you can use wildcards to fetch all files from a predefined level of subdirectories: /path/to/log/*/*.log. This fetches all .log files from the subfolders of /path/to/log. It does not fetch log files from the /path/to/log folder itself. If this setting is left empty, Filebeat will choose log paths based on your operating system.
var.project_id
Google Cloud project ID.
var.topic
Google Cloud Pub/Sub topic name.
var.subscription_name
Google Cloud Pub/Sub topic subscription name. If the subscription does not exist it will be created.
var.credentials_file
Path to a JSON file containing the credentials and key used to subscribe.
var.keep_original_message
Flag to control whether the original message is stored in the log.original field. Defaults to false, meaning the original message is not saved.

firewall fileset settingsedit

Example config:

- module: googleclcoud
  firewall:
    enabled: true
    var.project_id: my-gcp-project-id
    var.topic: googlecloud-vpc-firewall
    var.subscription_name: filebeat-googlecloud-vpc-firewall-sub
    var.credentials_file: ${path.config}/gcp-service-account-xyz.json
    var.keep_original_message: false
var.paths
An array of glob-based paths that specify where to look for the log files. All patterns supported by Go Glob are also supported here. For example, you can use wildcards to fetch all files from a predefined level of subdirectories: /path/to/log/*/*.log. This fetches all .log files from the subfolders of /path/to/log. It does not fetch log files from the /path/to/log folder itself. If this setting is left empty, Filebeat will choose log paths based on your operating system.
var.project_id
Google Cloud project ID.
var.topic
Google Cloud Pub/Sub topic name.
var.subscription_name
Google Cloud Pub/Sub topic subscription name. If the subscription does not exist it will be created.
var.credentials_file
Path to a JSON file containing the credentials and key used to subscribe.
var.keep_original_message
Flag to control whether the original message is stored in the log.original field. Defaults to false, meaning the original message is not saved.
