Upgrade Universal Profiling

Upgrade Universal Profiling

edit

Upgrade process

edit

To upgrade from all versions earlier than 8.10 (GA), you need to:

Perform a stack upgrade in Elastic Cloud
Stop profiling data ingestion
Delete existing profiling data
Setup Universal Profiling from scratch
Start profiling data ingestion

To upgrade from version 8.10 or later, you need to:

Perform a stack upgrade in Elastic Cloud

Perform a stack upgrade in the Elastic Cloud console

edit

To perform a stack upgrade in Elastic Cloud:

Locate the deployment you wish to upgrade in Elastic Cloud.
Click the Manage deployment icon next to your deployment to open the deployment settings.
Find Deployment version on the right side of the page.
Click Upgrade, and choose the desired version.
Verify the upgrade was successful under Your deployment → Activity in the navigation menu.

Stop profiling data ingestion

edit

During the Universal Profiling upgrade, you must stop data ingestion.

If you have an automated host-agent setup and control of the full fleet of machines where the host-agent is installed, deleting all host-agent deployments stops ingestion.

If you do not have direct control of all host-agent deployments, you can stop data ingestion by stopping incoming requests to the Integrations Server. To do this:

From the deployment settings, scroll down to the Instances section and locate all Integrations Server instances.
Click the three vertical dots in the upper-right corner of the Integrations Server card.
Select Stop routing requests.
Repeat this process for all Integrations Server instances.

When stopping incoming requests, host-agent replicas back off and retry connecting to the Elastic Cloud endpoint at increasing time intervals.

Delete existing profiling data

edit

You can delete existing profiling data in Kibana:

If you’re upgrading from 8.9.0 or later, go to Dev Tools from the navigation menu, and execute the following snippet. If you’re upgrading from an earlier version, skip this step.
```
PUT /_cluster/settings
{
  "persistent": {
    "xpack.profiling.templates.enabled": false
  }
}
```
From the navigation menu, go to Stack Management → Index Management.
Make sure you’re in the Data Streams tab, and search for profiling- in the search bar.
Select all resulting data streams, and click the Delete data streams button.
Switch to the Indices tab, enable Include hidden indices, and search for profiling- in the search bar.
Select all resulting indices, click the Manage indices button, and select Delete indices from the drop-down menu.
Switch to the Index Templates tab, and search for profiling- in the search bar.
Select all resulting index templates, and click the Delete templates button.
Switch to the Component Templates tab, and search for profiling- in the search bar.
Select all resulting component templates, and click the Delete component templates button.
From the navigation menu, go to Index Lifecycle Policies, search for profiling in the search bar, and click the trash icon in the Actions column.

Verify that no ingestion is happening by reloading the Data Streams and Indices pages and ensuring that there are no data streams or indices with the profiling- prefix.

Set up Universal Profiling from scratch

edit

Refer to Configure data ingestion to set up Universal Profiling from scratch.

Start profiling data ingestion

edit

If you stopped ingesting data by stopping routing requests to the Integrations Server, re-enable traffic following the same steps but click Start routing requests instead of Stop routing requests.

Verify the update succeeds

edit

Click any subheadings under Universal Profiling in the navigation menu. You should see incoming data.

If you see instructions on how to deploy the host-agent like in the examples from the Get Started documentation, the agents did not reconnect to the Integrations Server replicas.

Refer to the troubleshooting documentation and the Get Started documentation to investigate the issue.
