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 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, or both.
App Visibility collector database sizing
The App Visibility collector database must be scaled to your environment. To calculate the maximum database size, use the following equation:
5 GB x number of Agents = maximum database size
The equation is based on the following environmental factors:
- Average request size on the App Visibility agent: up to 256 KB
- Average number of entry points: 200 every five minutes
- App Visibility collector database retention period: 35 days (default)
Significant changes to any of the factors affects the database size requirements accordingly.
The default maximum database size is 100 GB, which is enough for 20 App Visibility agents in the aforementioned 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 = 200
- 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 = 1000 (divided among 5 App Visibility collectors or less)
- 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 components are installed together, approximately 2.1 GB of disk space is required.
App Visibility portal sizing
Disk space requirements for the App Visibility portal software and database are the same, no matter how many App Visibility collectors are used.
To install the App Visibility portal software and database, the computer must have approximately 2 GB of free disk space.
If all components are installed together, approximately 2.1 GB of disk space is required.
App Visibility proxy sizing
To install the App Visibility proxy software, the computer must have approximately 400 MB of free disk space.
If all components are installed together, approximately 2.1 GB of disk space is required.
Only one App Visibility portal can be configured 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.
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, 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
Based upon the calculated size of your deployment, select the appropriate equipment for optimum performance.
App Visibility server resources for different deployment sizes Size of deployment Number of agents CPUs required Memory required Disk size Small 20 2 CPUs, 2 GHz each 8 GB RAM 100 GB Medium 100 2 CPUs, 2 GHz each 8 GB RAM 260 GB Large 200 4 CPUs, 2 GHz each 16 GB RAM 550 GB Extra Large 500 8 to 16 CPUs, 2 GHz each 32 GB RAM 2100 GB* * Divide the required disk size between the number of collectors: <diskSize> / <numberOfCollectors>
