OneAgent diagnostics

You can run fully automated OneAgent troubleshooting for Dynatrace SaaS and Managed environments starting with Dynatrace version 1.208.

The workflow enables you to:

  • Automatically pinpoint a OneAgent-related issue in highly dynamic environments, at a specific point in time
  • Easily collect the diagnostic data for a specific entity, and automatically get potential solutions for detected anomalies
  • Quickly resolve common issues on your own, reducing the amount of time spent on diagnosing
  • Directly provide Dynatrace Support all the details they need to diagnose the issue
Command-line diagnostics

If you don't have access to Dynatrace or you would like to script diagnostic data collection, you can use the oneagentctl command to collect a subset of full diagnostics data right on the host where OneAgent is installed. For more information, see Create support archive.

Requirements

  • Dynatrace SaaS environment: Dynatrace version 1.202+
  • Dynatrace Managed environment: Dynatrace version 1.208+
  • View sensitive request data environment permission

Analyze automatically

This procedure describes the default procedure: Dynatrace collects diagnostics data for a host or process and immediately analyzes it.

If you prefer to collect and review the data before manually submitting it to Dynatrace for analysis, see Collect and review locally.

  1. Go to Hosts or Hosts Classic (latest Dynatrace).

  2. Select the host you want to troubleshoot.

  3. Run diagnostics on the host or process level.

    • Host level: on the host page, open the browse menu () and select Run OneAgent diagnostics.

      OneAgent diagnostics: menu item

    • Process level: on the host page, open a process page, and then select Run OneAgent diagnostics from the browse menu () on the process page.
  4. On the Run Dynatrace OneAgent diagnostics page, briefly describe what isn’t working as expected from your point of view.

    OneAgent diagnostics: run

  5. optional By default, 24 hours (1 day) of data is collected for analysis. If you need more data, select the Advanced options link, change the number of days, and select Apply.

  6. Select Start analysis.

What happens next

Dynatrace does the following:

  • Collects diagnostic data for the last 24 hours (if you didn't change the default) of the affected host or process
  • Stores the collected diagnostic data
  • Uploads the diagnostic data to an S3 bucket in the AWS region of your environment for further analysis

The State column describes the current phase of the process.

State does not automatically refresh. Select Refresh to check for a state change.

Data collection is in progress. While collecting data, you can:

  • Refresh the page to update the progress.
  • Cancel diagnostic data collection.

Dynatrace has finished collecting diagnostic data. After collecting data, you can:

  • Analyze to submit the collected data to Dynatrace for analysis.
  • Download the collected data locally for your inspection.
  • Delete the issue, including the collected diagnostic data.

Diagnostic data is being transferred to Dynatrace for analysis. While sending data, you can:

  • Refresh the page to update the progress.
  • Download the collected diagnostic data.
  • Delete the issue, including the collected diagnostic data.

Diagnostic data has been transferred to Dynatrace for analysis.

Dynatrace is now analyzing the diagnostic data.
While analyzing data, you can:

  • Refresh the page to update the progress.
  • Download the collected diagnostic data.
  • Delete the issue, including the collected diagnostic data.

The analysis is done. The number of associated alerts is shown in parentheses.
After an analysis, you can:

  • Download the collected diagnostic data.
  • Delete the issue, including the collected diagnostic data.

The diagnostic data is being deleted. While deleting data, you can:

  • Refresh the page to update the progress.

The diagnostic data has been deleted. Dynatrace keeps only a small set of information about who, when, where, and why the diagnostic data was collected.

The diagnostics process was canceled manually before it was finished.

Review the Dynatrace analysis

When the analysis is complete, Dynatrace sends the results back to your environment. If a potential solution is identified, Dynatrace lists it in the Alerts section.

OneAgent diagnostics: alerts

In this example, you can see that the fully automated OneAgent troubleshooting workflow has detected that this OneAgent was mounted on a network file system (NFS), which isn’t supported. Instructions for resolving the issue are included.

Collect and review locally

This procedure describes how to collect diagnostics data for a host or process locally. Use this option if you prefer to collect and review the data before manually submitting it to Dynatrace for analysis.

If you instead want to collect data and submit it to Dynatrace automatically for analysis, see Analyze automatically.

  1. Go to Hosts or Hosts Classic (latest Dynatrace).

  2. Select the host you want to troubleshoot.

  3. Run diagnostics on the host or process level.

    • Host level: on the host page, open the browse menu () and select Run OneAgent diagnostics.

Data privacy

To comply with regional data protection and privacy regulations, Dynatrace does the following:

  • Masks some personal data before storing a support archive in Cassandra and uploading it to an AWS S3 bucket. For example, IBANs and URI credentials are replaced with <masked>. However, some personal data may not be masked.

  • Writes audit log messages when support archives are created, analyzed, accessed, and deleted to ensure transparency in the use of support archives.

  • Provides access to OneAgent support archives only to users that have the View sensitive request data environment permission.

  • Automatically deletes all diagnostic data 30 days after its collection.

    This applies to the data in your Dynatrace environment. You can also choose to delete collected diagnostic data earlier.

For related details on OneAgent diagnostics, check the following pages:

Troubleshooting

  • If Dynatrace cannot collect diagnostic data within 20 minutes, it automatically tries again.
  • If the retry fails as well, we suggest that you contact a Dynatrace product expert via live chat.

State does not automatically refresh. Select Refresh to check for a state change.

Frequently asked questions

No, you cannot access the S3 directly or use your own.

OneAgent diagnostics uploads the diagnostic data to the Dynatrace S3 bucket that is configured for the environment/cluster by Dynatrace. The S3 bucket used depends on the location of the environment/cluster.
