Performance and scalability recommendations for integrations with CMDB

 

This topic presents recommendations and considerations for TrueSight Infrastructure Management integration with CMDB.

Timing for event and impact management operations

This topic presents timing approximations for operations in an environment that includes event and impact management:

The following environment is used as a sample for the timing estimates.

MetricAmount or value
Number of CIs50 K
Number of service models3
Number of levels

6

Number of events per day400 K
Maximum number of CIs in a service model20 K
Number of impact events out of 400 K312 K

Publish times

The following table shows the amount of time it takes to publish a new service model in each environment

EnvironmentPublish time
Small (5 K CIs and relationships)32 minutes
Medium (10 K CIs and relationships)39 minutes
Large (20 K CIs and relationships)

1 hour

The following table shows the amount of time it takes to publish a service model in which 1,000 CIs and relationships are added, updated, or deleted. Times are measured on a large environment.

Sizing chart for BMC Cloud Life Cycle Management

The following table can help you determine the number of required TrueSight Infrastructure Management Central Servers, TrueSight Infrastructure Management Child Servers, Data Collection Hosts, and BMC Server Automation Servers. The table also shows the maximum number of devices, monitor instances, and attributes for a proof of concept (POC) and large environments in BMC Cloud Lifecycle Management.

About a POC deployment

In a POC deployment, all of the components for BMC Cloud Life Cycle Management, such as the TrueSight Infrastructure Management Central Server, Child Server, and Data Collection Host, are on the same computer.
