Scenario 1. Service Discovery Only

This chapter describes the scenario that you run Service Discovery only.

Objectives

The following table lists the expected time to complete all service discoveries based on the data we collected in performance tests.

Number of Services First Run of Service Discovery Scheduled Rerun of Service Discovery
<100 <4 hours <4 hours
<500 <12 hours <12 hours

Note Scheduled Rerun of Service Discovery means rerun all service discoveries on a periodic basis, and the interval can be adjusted.

Test Environment

The performance tests are performed on an environment that meets the following preconditions:

  • One service consists of less than 30 Running Software instances, which run on different hosts.
  • One host can be discovered by the Host Discovery by Shell job within two minutes if everything works as expected.

Note  

  • If the actual environment cannot meet these preconditions, the Service Discovery performance may not reach the above objectives. In this case, you can adjust several configuration settings to improve the Service Discovery performance.

  • There is no CI and Relationship discovered by Universal Discovery.
  • The numbers of CIs and Relationships reported by Service Discovery are shown in the table below.
