Collecting Logs for the Acquia App

This section provides instructions for configuring log collection from Acquia and sending those logs to Sumo Logic for monitoring and analysis in the Acquia App predefined dashboards and searches.

Sumo Logic enables you to collect logs from Acquia, with the ability to configure the log types to be collected. The logs are then forwarded to a Sumo Logic Cloud Syslog Source.

Step 1: Configure a collector

This section walks you through the process of creating a new Sumo Logic hosted collector.

To create a new Sumo Logic hosted collector, do the following:

  1. In the main Sumo Logic menu, select Manage Data > Collection > Collection.
  2. Click Add Collector.
  3. Click Hosted Collector.
  4. Provide a Name for the Collector.
  5. A description is optional.
  6. Category. Enter any string to tag the logs collected from this Collector. This Source Category value is stored in a searchable metadata field called _sourceCategory. See our Best Practices: Good Source Category, Bad Source Category.
  7. Click the +Add Field link in the Fields section to define the fields you want to associate, each field needs a key and value.
    • green check circle.png A green circle with a check mark is shown when the field exists in the Fields table schema.
    • orange exclamation point.png An orange triangle with an exclamation point is shown when the field doesn't exist in the Fields table schema. In this case, an option to automatically add the nonexistent fields to the Fields table schema is provided. If a field is sent to Sumo that does not exist in the Fields schema it is ignored, known as dropped.
  8. Assign to a Budget allows you to assign an ingest budget to the Collector. The dropdown displays your ingest budgets in the following format:
<budget name> (<field value>) (<allocated capacity>)
  1. Time Zone. Set the default time zone when it is not extracted from the log timestamp. Time zone settings on Sources override a Collector time zone setting.
  2. Review your input and when finished click Save.

After the Collector has been set up, it appears on the Collection page as a Hosted Collector.

Step 2: Configure a source

This task shows you how to configure a cloud syslog source for Acquia log collection.

Prerequisites

It's helpful to know the options you'll need to set before starting a procedure. When you're configuring a cloud syslog source, be sure to specify the following configurations:

  • Source:
    • Name. (Required) A name is required, the Description is optional.
    • Source Category. (Required) The Source Category metadata field is a fundamental building block to organize and label Sources. Example: Acquia. For more information, see Best Practices.
  • Advanced
    • Enable Timestamp Parsing. True
    • Time Zone. Logs are in UTC by default
    • Timestamp Format. Auto Detect
note

Be sure to copy and paste your token in a secure location. You'll need this when you configure Syslog Settings.

Sumo Logic SSL certificate

In the procedure below, you'll configure a Cloud Syslog Source. This will generate a Sumo Logic token and the endpoint hostname. Then you'll set up TLS by downloading a cert to your server. Download the DigiCert certificate from one of the following locations:

Configuring a cloud syslog source

Cloud syslog configuration requires a token that is automatically generated when you configure a cloud syslog source. The token allows Sumo to distinguish your log messages from those of other customers. The token is tied to the source, but not to any specific user.

Include the token as the Structured ID in every syslog message that is sent to Sumo Logic. The token is removed by Sumo Logic during ingestion and is not included with your syslog message in search results.

The token is deleted if you delete the source. To change a token, use the Regenerate Token option as described in the following procedure.

To configure a cloud syslog source, do the following:

  1. In Sumo Logic, select Manage Data > Collection > Collection.
  2. On the Collection page, click Add Source next to a Hosted Collector. See Set up a Hosted Collector for information on adding Hosted Collectors.
  3. Select Cloud Syslog.
  4. Enter a Name to display for this source in Sumo. Description is optional.
  5. (Optional) For Source Host and Source Category, enter any string to tag the output collected from this source. (Category metadata is stored in a searchable field called _sourceCategory).
  6. Fields. Click the +Add Field link to add custom log metadata Fields. Define the fields you want to associate. Each field needs a name (key) and value.
    • green check circle.png A green circle with a check mark is shown when the field exists and is enabled in the Fields table schema.
    • orange exclamation point.png An orange triangle with an exclamation point is shown when the field doesn't exist, or is disabled, in the Fields table schema. In this case, an option to automatically add or enable the nonexistent fields to the Fields table schema is provided. If a field is sent to Sumo that does not exist in the Fields schema or is disabled it is ignored, known as dropped.
  7. Set any of the following under Advanced:
    • Enable Timestamp Parsing. This option is selected by default. If it's deselected, no timestamp information is parsed.
    • 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 important to have the proper time zone set, no matter which option you choose. If the time zone of logs cannot be determined, Sumo Logic assigns the UTC time zone; if the rest of your logs are from another time zone your search results will be affected.
    • Timestamp Format. By default, Sumo will automatically detect the timestamp format of your logs. However, you can manually specify a timestamp format for a source. See Timestamps, Time Zones, and Time Ranges, and Date Formats.
  8. Create any Processing Rules you'd like for the new source.
  9. Click Save. The token information is displayed in a read-only dialog box, shown below.
  10. Click Copy to copy the information for use in the syslog client. The information is copied in the following format:
Token: 9HFxoa6+lXBmvSM9koPjGzvTaxXDQvJ4POE/WCURPAo+w4H7PmZm8H3mSEKxPl0Q@41123, Host: syslog.collection.YOUR_DEPLOYMENT.sumologic.com, TCP TLS Port: 6514

The number 41123 in the token is the Sumo Private Enterprise Number (PEN). There are two options for including the token. You can include it in the structured data field or in the message body.

In the following example, the token is in the structured data field.

<165>1 2015-01-11T22:14:15.003Z mymachine.example.com evntslog - ID47 [YOUR_TOKEN] msg

In the following example, the token is in the message body.

<165>1 2015-01-11T22:14:15.003Z mymachine.example.com evntslog - ID47 - YOUR_TOKEN msg

RFC 5424 limits the structured data field (SD-ID) to 32 characters, however our token is 64 characters long. If your logging client enforces this limit you will need to pass the token in the message body. 11. After configuring the source, you can perform these token operations from the Collectors and Sources page:

  • Click Show Token to display the token for a cloud syslog source at any time.
  • Click Regenerate Token if you need to generate a new token.

Step 3: Configure logging for Acquia

In order to start ingesting Acquia Cloud logs you must setup log forwarding in Acquia Cloud.

To configure Acquia log forwarding, follow the instructions in the Acquia documentation.

Viewing Acquia 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 Filter 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.
