Collecting logs and metrics for the Amazon Redshift ULM app

This section has instruction for setting up collection of logs and metrics for the Amazon Redshift ULM app.

Step 1. Plan source categories

Before you configure the log and metric sources for the Amazon Redshift app, decide on the source category you will assign to each. A hierarchical approach allows you to make use of wildcards when you perform searches. For example:

• For the AWS S3 source for Amazon Redshift Audit logs collection, you could specify a source category of AWS/Redshift/Audit.
• For the AWS CloudTrail source for Redshift CloudTrail Events, you could specify a source category of AWS/CloudTrail.
• For the AWS CloudWatch source for Redshift metrics, you could specify a source category of AWS/Metric/Redshift.

Step 2. Enable Amazon Redshift Audit logging

In this step, you enable audit logging for Amazon Redshift.

1. Enable database audit logging. For background information, see Database Audit Logging. For instructions on enabling audit logging, see Configuring Auditing Using the Console.

2. Enable user activity logging. For the user activity log, you must also enable the enable_user_activity_logging database parameter. If you enable only the audit logging feature, but not the associated parameter, the database audit logs will log information for only the connection log and user log, but not for the user activity log. The enable_user_activity_logging parameter is disabled (false) by default, but you can set it to true to enable the user activity log. For more information, see Amazon Redshift Parameter Groups.

   Create a new parameter group with required parameter values and then modify cluster to use the new parameter group. If you want to use an existing parameter group, you can modify it with AWS CLI. For more information, see Amazon Redshift Parameter Groups.

For information about connection logs and user logs, see STL_CONNECTION_LOG and STL_USERLOG in AWS help.

Step 3: Configure Amazon S3 source for Amazon Redshift Audit logs collection

1. Configure a Hosted Collector.
2. To your Hosted Collector, add an Amazon S3 Source.
   • Name. Enter a name to display for the new Source.
   • Description. Enter an optional description.
   • S3 Region. Select the Amazon Region for your Redshift Audit Log S3 bucket.
   • Bucket Name. Enter the exact name of your Redshift Audit Log S3 bucket.
   • Path Expression. Enter the string that matches the S3 objects you'd like to collect. You can use a wildcard (*) in this string. (DO NOT use a leading forward slash. See Amazon Path Expressions.) The S3 bucket name is not part of the path. Don’t include the bucket name when you are setting the Path Expression.
   • Source Category. AWS/Redshift/Audit
   • Access Key ID and Secret Access Key. Enter your Amazon Access Key ID and Secret Access Key.
   • Scan Interval. Use the default of 5 minutes. Alternately, enter the frequency Sumo Logic will scan your S3 bucket for new data.
   • Enable Timestamp Parsing. Select the Extract timestamp information from log file entries check box.
   • Time Zone. Select Ignore time zone from the log file and instead use, and select UTC from the dropdown.
   • Timestamp Format. Select Automatically detect the format.
   • Enable Multiline Processing. Select the Detect messages spanning multiple lines check box, and select Infer Boundaries.
3. Click Save.

Step 4. Configure AWS CloudTrail source for Redshift CloudTrail Events

1. Configure a Hosted Collector.
2. To your Hosted Collector, add an AWS CloudTrail Source.
   • Name. Enter a name to display for the new Source.
   • Description. Enter an optional description.
   • S3 Region. Select the Amazon Region for your CloudTrail Redshift S3 bucket.
   • • Bucket Name. Enter the exact name of your CloudTrail Redshift S3 bucket.
   • Path Expression. Enter the string that matches the S3 objects you'd like to collect. You can use a wildcard (*) in this string. (DO NOT use a leading forward slash. See Amazon Path Expressions..)The S3 bucket name is not part of the path. Don’t include the bucket name when you are setting the Path Expression.
   • Source Category. Enter a source category. For example, AWS/CloudTrail.
   • Access Key ID and Secret Access Key. Enter your Amazon Access Key ID and Secret Access Key.
   • Scan Interval. Use the default of 5 minutes. Alternately, enter the frequency Sumo Logic will scan your S3 bucket for new data.
   • Enable Timestamp Parsing. Select the checkbox.
   • Time Zone. Select Ignore time zone from log file and instead use, and select UTC.
   • Timestamp Format. Select Automatically detect the format.
   • Enable Multiline Processing. Select the checkbox, and select Infer Boundaries.
3. Click Save.

Step 5: Configure AWS CloudWatch source for Redshift metrics

1. Configure a Hosted Collector.
2. Configure an AWS CloudTrail Source.
   1. Name. Enter a name to display for the new Source.
   2. Description. Enter an optional description.
   3. Regions. Select your Amazon Regions for Amazon Redshift.
   4. Namespaces. Select AWS/Redshift.
   5. Source Category. Enter a source category. For example, AWS/Metric/Redshift.
   6. Access Key ID and Secret Access Key. Enter your Amazon Access Key ID and Secret Access Key.
   7. Scan Interval. Use the default of 5 minutes, or enter the frequency Sumo Logic will scan your CloudWatch Sources for new data.
3. Click Save.

Installing the Amazon Redshift ULM app

To install the app, do the following:

1. Select App Catalog.
2. In the 🔎 Search Apps field, run a search for your desired app, then select it.
3. Click Install App.
   note

   Sometimes this button says Add Integration.

4. Click Next in the Setup Data section.
5. In the Configure section of your respective app, complete the following fields.
   1. Key. Select either of these options for the data source.
      • Choose Source Category and select a source category from the list for Default Value.
      • Choose Custom, and enter a custom metadata field. Insert its value in Default Value.
6. Click Next. You will be redirected to the Preview & Done section.

Post-installation

Once your app is installed, it will appear in your Installed Apps folder, and dashboard panels will start to fill automatically.

Each panel slowly fills with data matching the time range query and received since the panel was created. Results will not immediately be available, but will update with full graphs and charts over time.

Viewing Amazon Redshift ULM dashboards​

All dashboards have a set of filters that you can apply to the entire dashboard. Use these filters to drill down and examine the data to a granular level.

• You can change the time range for a dashboard or panel by selecting a predefined interval from a drop-down list, choosing a recently used time range, or specifying custom dates and times. Learn more.
• You can use template variables to drill down and examine the data on a granular level. For more information, see Filtering Dashboards with Template Variables.
• Most Next-Gen apps allow you to provide the scope at the installation time and are comprised of a key (_sourceCategory by default) and a default value for this key. Based on your input, the app dashboards will be parameterized with a dashboard variable, allowing you to change the dataset queried by all panels. This eliminates the need to create multiple copies of the same dashboard with different queries.
