The Sumo Logic app for Google Cloud SQL helps you monitor your usage of Google Cloud SQL. The preconfigured dashboards provide insight into created and deleted resources, messages, authorization failures, user activities, and error logs.

Log Types

The App uses:

Sample Query

Created Resources Over Time
_sourceCategory=*gcp* data "type":"cloudsql_database" methodName
| parse regex "\"logName\":\"(?<log_name>[^\"]+)\""
| where log_name matches "projects/*/logs/*"
| json "message.data.resource.labels", "message.data.protoPayload.methodName" as labels, method
| json field=labels "database_id", "project_id", "region" as instance, project, region
| json "message.data.protoPayload.authorizationInfo[*]" as permissions
| parse regex field=permissions "\"permission\":\"(?<resource_type>[^\"]+)\.(?<method>[^\"]+?)\"" multi
| where method = "create"
| timeslice 1h
| count as creations by _timeslice, resource_type
| transpose row _timeslice column resource_type

Collecting Logs for Google Cloud SQL

This section describes the Sumo pipeline for ingesting logs from Google Cloud Platform (GCP) services, and provides instructions for collecting logs from Google Cloud SQL.

Collection Process for GCP Services

The key components in the collection process for GCP services are Google Logs Export, Google Cloud Pub/Sub, and Sumo’s Google Cloud Platform (GCP) source running on a hosted collector.

The GCP service generates logs which are exported and published to a Google Pub/Sub topic through Stackdriver. You will then set up a Sumo Logic Google Cloud Platform source that subscribes to this topic and receives the exported log data.

Google integrations

Configuring collection for GCP uses the following process:

  1. Configure a GCP source on a hosted collector. You'll obtain the HTTP URL for the source.
  2. Create a topic in Google Pub/Sub and subscribe the GCP source URL to that topic.
  3. Create an export of GCP logs from Google Stackdriver Logging. Exporting involves writing a filter that selects the log entries you want to export, and choosing a Pub/Sub as the destination. The filter and destination are held in an object called a sink.

See the following sections for configuration instructions.

note

Logs from GCP services can be exported to any destination including Stackdriver. It is not required to push the GCP logs into Stackdriver for the Sumo Logic Apps to work. Any GCP logs can be excluded from Stackdriver logging and still can be exported to Sumo logic.

Configure a Google Cloud Platform Source

The Google Cloud Platform (GCP) Source receives log data from Google Pub/Sub.

note

You can use the same GCP Source to receive log data from multiple GCP services. For example, you can send logs collected from Google Cloud Application Engine, Google Cloud IAM, and Google Cloud Audit.

However, this is not recommended since you cannot define specific Source Category values to each GCP service. If you create a GCP Source for each service you can define a specific Source Category to each service.

This Source will be a Google Pub/Sub-only Source, which means that it will only be usable for log data formatted as data coming from Google Pub/Sub.

  1. In Sumo Logic, select Manage Data > Collection > Collection.
  2. Select an existing Hosted Collector upon which to add the Source. If you don't already have a Collector you'd like to use, create one, using the instructions on Configure a Hosted Collector.
  3. Click Add Source next to the Hosted Collector and click Google Cloud Platform.
  4. Enter a Name to display for the Source. A Description is optional.
    Google integrations
  5. Source Host (Optional). The Source Host value is tagged to each log and stored in a searchable metadata field called _sourceHost. Avoid using spaces so you do not have to quote them in keyword search expressions. This can be a maximum of 128 characters.
  6. Source Category (Optional). The Source Category value is tagged to each log and stored in a searchable metadata field called _sourceCategory. See our Best Practices: Good Source Category, Bad Source Category. Avoid using spaces so you do not have to quote them in keyword search expressions. This can be a maximum of 1,024 characters.
  7. Fields. Click the +Add Field link to add custom log metadata Fields, then define the fields you want to associate. Each field needs a name (key) and value. Look for one of the following icons and act accordingly:
  • orange exclamation point.png If an orange triangle with an exclamation point is shown, use the option to automatically add or enable the nonexistent fields before proceeding to the next step. The orange icon indicates that the field doesn't exist, or is disabled, in the Fields table schema. If a field is sent to Sumo that does not exist in the Fields schema or is disabled it is ignored, known as dropped.
  • green check circle.png If a green circle with a checkmark is shown, the field exists and is already enabled in the Fields table schema. Proceed to the next step.
  1. Advanced Options for Logs.
    Google integrations
  • Timestamp Parsing. This option is selected by default. If it's deselected, no timestamp information is parsed at all.
  • Time Zone. There are two options for Time Zone. You can use the time zone present in your log files, and then choose an option in case time zone information is missing from a log message. Or, you can have Sumo Logic completely disregard any time zone information present in logs by forcing a time zone. It's very important to have the proper time zone set, no matter which option you choose. If the time zone of logs can't be determined, Sumo Logic assigns logs UTC; if the rest of your logs are from another time zone your search results will be affected.
  • Timestamp Format. By default, Sumo Logic will automatically detect the timestamp format of your logs. However, you can manually specify a timestamp format for a Source. See Timestamps, Time Zones, Time Ranges, and Date Formats for more information.
  1. Processing Rules. Configure any desired filters, such as allowlist, denylist, hash, or mask, as described in Create a Processing Rule.
  2. When you are finished configuring the Source, click Save.

Configure a Pub/Sub Topic for GCP

You need to configure a Pub/Sub Topic in GCP and add a subscription to the Source URL that belongs to the Sumo Logic Google Cloud Platform Source you created. Once you configure the Pub/Sub, you can export data from Google Logging to the Pub/Sub. For example, you can export Google App Engine logs, as described on Collect Logs for Google App Engine.

  1. Create a Pub/Sub Topic in GCP. See Google Cloud documentation for the latest configuration steps.
  2. Create a Pub/Sub subscription to the Source URL that belongs to the Sumo Logic Google Cloud Platform Source you created. See Google Cloud documentation for the latest configuration steps.
    • Use a Push Delivery Method to the Sumo Logic Source URL. To determine the URL, navigate to the Source on the Collection page in Sumo Logic and click Show URL.

Limitations

Google limits the volume of data sent from a Topic. Our testing resulted in the following data limits:

TopicsMegabytes per secondPayload size
One18 MBps (1.5 TB/day)100 KB
One6 MBps (0.5 TB/day)2.5 KB
note

These limits may vary based on your setup and are based on our previous tests.

We recommend the following:

  • Shard messages across topics within the above data limits.
  • Ask GCP to increase the allowable capacity for the topic.

Create export of Cloud SQL logs from Google Logging

In this step you export logs to the Pub/Sub topic you created in the previous step.

  1. Go to Logging and click Logs Router.
    Google integrations
  2. Click Create Sink.
    Google integrations
  3. As part of Create logs routing sink, add the following information.
  4. Enter a Sink Name. For example, "gce-vm-instance".
  5. Select "Cloud Pub/Sub" as the Sink Service.
  6. Set Sink Destination to the Pub/Sub topic you created in the Google Cloud Platform Source procedure. For example, "pub-sub-logs".
  7. In Choose logs to include in sink section for resource_type, replace "<resource_variable>" with "cloudsql_database".
  8. Click Create Sync.

Installing the Google Cloud SQL App

Now that you have set up the collection for Google Cloud SQL, install the Sumo Logic App Google Cloud SQL to use the pre-configured searches and dashboards that provide visibility into your environment for real-time analysis of overall usage.

To install the app:

  1. From the Sumo Logic navigation, select App Catalog.
  2. In the Search Apps field, search for and then select your app.
    App_Catalog.png
  3. Optionally, you can scroll down to preview the dashboards included with the app. Then, click Install App (sometimes this button says Add Integration).
    note

    If your app has multiple versions, you'll need to select the version of the service you're using before installation.

  4. On the next configuration page, under Select Data Source for your App, complete the following fields:
    • Data Source. Select one of the following options:
      • Choose Source Category and select a source category from the list; or
      • Choose Enter a Custom Data Filter, and enter a custom source category beginning with an underscore. For example, _sourceCategory=MyCategory.
    • Folder Name. You can retain the existing name or enter a custom name of your choice for the app.
    • All Folders (optional). Default location is the Personal folder in your Library. If desired, you can choose a different location and/or click New Folder to add it to a new folder.
  5. Click Next.
  6. Look for the dialog confirming that your app was installed successfully.
    app-success.png

Once an app is installed, it will appear in your Personal folder or the folder that you specified. From here, you can share it with other users in your organization. Dashboard panels will automatically start to fill with data matching the time range query received since you created the panel. Results won't be available immediately, but within about 20 minutes, you'll see completed graphs and maps.
