A10 load balancer discovery

Discovery and Service Mapping uses patterns to collect information about A10 load balancers.

주:

Probe-to-pattern migration is supported for the New York release and later. See the knowledge article KB0694477 for more information.

The following patterns support the A10 load balancer discovery:

• A10 Load Balancer
• A10 Load Balancer SSH
• A10

The A10 IP Source NAT (Network Address Translator) is an extension of the A10 Load Balancer Pattern. The IP Source NAT Pattern extension discovers IP Source NAT pools. This extension is available on Store from the February 2023 release, Store version 1.0.98.

Request apps on the Store

Visit the ServiceNow Store to view all the available apps, and for information about submitting requests to the store. For cumulative release notes information for all released apps, see the ServiceNow Store version history release notes.

Prerequisites

Credentials

Configure SNMP credentials or (optionally) SSH credentials.

Discovery and Service Mapping Patterns application

To discover A10 load balancer partitions, deploy Discovery and Service Mapping Patterns application 1.0.98 release from the ServiceNow Store.
