Consider the following sizing and scalability guidelines when planning your BMC TrueSight App Visibility Manager deployment. These guidelines also apply to deployment of BMC Synthetic Transaction Execution Adapter (TEA) Agents.

Note

The values provided in this topic are estimations, meant as general guidelines for an out-of-the-box configuration, and they do not take all contributing factors (such as the number of metrics and events) into account. If you have values in any of the listed categories that are exceptional, then you should consult with BMC Support. You must monitor your data in the first few days, and based on your results, adjust the database retention period, database size, number of App Visibility collectors, or installed hardware.

App Visibility collector database sizing

The App Visibility collector database must be scaled for the number of App Visibility agents in your environment. To calculate the maximum database size, use the following equation:

10 GB x number of agents = maximum database size

The default maximum database size is 100 GB, which is enough for 10 App Visibility agents in an average environment. For information about changing the App Visibility collector database settings, see Changing App Visibility collector settings.

Maximum number of components per deployment

Apply the following guidelines to your deployment, per tenant:

  • Maximum number of App Visibility agents or synthetic TEA Agents per App Visibility collector = 100
  • Maximum number of App Visibility collectors per App Visibility portal = 5
  • Maximum number of App Visibility agents or synthetic TEA Agents per App Visibility portal = 500 (divided among 5 App Visibility collectors)
  • Maximum number of App Visibility portals per Presentation Server = 1

App Visibility collector sizing

To install the App Visibility collector software and database, the computer must have approximately 2 GB of free disk space.

If all App Visibility server components are installed together, such as for a very small environment or a test environment, approximately 2.1 GB of disk space is required.

App Visibility portal sizing

To install the App Visibility portal software and database, the computer must have approximately 2 GB of free disk space.

Disk space requirements are the same, even if many App Visibility collectors are used.

If all App Visibility server components are installed together, such as for a very small environment or a test environment, approximately 2.1 GB of disk space is required.

You can configure only one App Visibility portal per tenant with the Presentation Server. For deployment guidance, see also Operations Management basic deployment with App Visibility Manager and Operations Management service provider and tenant deployment.

App Visibility proxy sizing

To install the App Visibility proxy software, the computer must have approximately 400 MB of free disk space.

If all App Visibility server components are installed together, such as for a very small environment or a test environment, approximately 2.1 GB of disk space is required.

Synthetic TEA Agent sizing

A single synthetic TEA Agent can process up to 120 Execution Plans when the Execution Plan references a single web-based script. This limit is set by the system.

If your scripts produce a high volume of user-interface transactions, such as browser-driven scripts, BMC recommends that you limit the TEA Agent to 50 scripts.

There is no limit to the number of TEA Agents that you can install on a single computer.

For information about Execution plans, see Editing an application's synthetic settings.

Hardware sizing for deployments

Based upon the calculated size of your deployment, select the appropriate equipment for optimum performance.

*For large and extra large deployments, increase the heap size on your collector to 6 GB. See Changing the heap size on App Visibility components for more details.

Calculations are for transactions using the URLChecker script, with 10 custom timers or page timers per transaction, and approximately 20% of transactions with 1 error each. For transactions that don't use timers and have fewer errors, database size requirements may be smaller.

Database size calculations assume a retention period of 35 days.
