F5 BIG-IP LTM monitoring
This extension documentation is now deprecated and will no longer be updated. We recommend using the new F5 BIG-IP LTM extension for improved functionality and support.
Learn about F5 BIG-IP LTM Extension configuration, deployment and working with data.
Before you begin
Verify that your designated ActiveGate has the Extensions 2.0 module active and running.
- Go to Deployment Status > ActiveGates and expand the details of the designated ActiveGate.
- In the Properties section, make sure that the ActiveGate is assigned to a Group.
- In the Modules section, make sure that the Extensions 2.0 module is enabled.
If either of these properties needs to be changed, see Configuration properties and parameters of ActiveGate.
Any changes done via ActiveGate configuration files require a restart of the ActiveGate and Extensions Execution Controller (EEC) services.
Extension deployment
In Dynatrace Hub, select and install F5 BIG-IP.
Monitoring configuration
- Make sure the expected version is displayed in the Versions list at the bottom of the page.
- Add your monitoring configuration by selecting Add monitoring configuration.
Define devices
Select Add device to define the devices from which you want to pull data and provide the device connection details:
- IP address or device name
- Port
- SNMP version and related authentication details
ActiveGate group
Choose the ActiveGate group to determine which ActiveGates will run the extension. When done, select Next step.
Customize the monitoring
The next step in extension activation is to customize monitoring. See the complete list of feature sets and the metrics collected.
Filters match entity names to include/exclude instances from monitoring. This makes the data more relevant and saves unnecessary license consumption. Filters work with a specific entity type and support the following syntax:
$eq(<str>)– check if<str>matches what you're filtering$prefix(...)– must begin with …$suffix(...)- must end with …$contains(...)– must contain …$and(<expr1>, <expr2>)– can be used to chain two or more of the above expressions with AND operator$or(<expr1>, <expr2>)– can be used to chain two or more of the above expressions with OR operator$not(<expr>)– can be used to negate an expression
For example, to exclude all Pools from the Common partition, you can add a filter: $not($prefix(/Common/))
The final step is to select Activate, which will communicate the monitoring configuration to the ActiveGate along with the extension that defines how data is being collected.
Data visualization and configuration
The extension is packaged with an overview dashboard that is published as soon as you add it to your environment. Go to Dashboards or Dashboards Classic (latest Dynatrace) and look for a preset dashboard called F5 BIGIP LTM Overview.
The dashboard gives an overview into the main components of the platform, as well as shortcuts to the lists of different entity types (in the Navigate to F5 entities section). This is currently the quickest way to navigate to the lists of entities. Otherwise, you can manually add the path into your URL bar: .../ui/entity/list/<entity-type>
Access individual entities from a list or by drilling down from one of the charts in order to get the full details:
