Enterprise Edition / Plugin Enterprise Edition
 
Note:
  • If you plan to store more historical data for monitors, make sure to allocate extra disk space. Environments with high monitoring frequency or many monitors may need additional storage to support extended data retention.
  • In AWS and Azure, 4 GB RAM is only available in burstable instance types. For a non-burstable option, we recommend using the M series in AWS and D series in Azure.
  • We strongly recommend assigning a dedicated Applications Manager-installed machine for production.
  • We do not recommend installing Applications Manager on NAS (Network-Attached Storage) as it could potentially affect the shutdown process of the PostgreSQL Database.
  • The above-mentioned memory does not include the memory used by OS, which should account for another 4 GB.
  • Solid-State Drives (SSD) are strongly recommended.
  • In Enterprise Edition setup, if number of Probe Servers are high, 16 GB RAM for the Central Server is recommended.
  • It is recommended to read the Best Practices Guide before going into production.
  • Support for Applications Manager 32-bit installations has been deprecated from March 31,2022. Existing customers refer this post for details.
  • Refer the System requirements for configuring Webpage Analyzer Monitors.

Note:
  • We strongly recommend assigning a dedicated machine for the EUM Agent for production purposes.
  • The recommendations are based on five steps per monitor. The configuration will vary depending on the load.
  • A maximum of 20 EUM Agents are allowed per Applications Manager instance.
  • RBM monitor with Edge playback is supported only on the Windows EUM agent.
The performance of the monitor is influenced by the following factors:
  • The number of steps added in the monitor
  • The polling interval of the monitor
  • The time taken for the page to load

Real User Monitoring System Requirements

RUM Agent have to be installed on a dedicated Windows / Linux machine - 8 GB RAM. RUM Agent can work with the Professional Edition and Enterprise Edition (with Probe Server) of Applications Manager.

Following table shows the recommended configuration of the system to deploy RUM agent in both Professional Edition / Plugin Professional Edition and Enterprise Edition / Plugin Enterprise Edition :

OSNo of MonitorsProcessorMemoryHard Disk
Windows (Windows 11/ 10 (or) Windows Server 2025/ 2022/ 2019/ 2016) /
Linux (Cent OS 7/ CentOS Stream 8 and above/ Debian/ Fedora/ openSUSE/ Oracle Linux/ RHEL 7, 8 and 9/ SUSE Linux Enterprise/ Ubuntu 14 to 22)		 1 - 20 2 Core / 2.0 GHz and above 8 GB RAM 40 GB
 
Given below are the good to have practices for RUM:
  • Each Applications Manager instance can support upto 20 RUM Agents.
  • On an average, a single RUM Agent can efficiently manage 5000 page views per minute i.e. 200 million page views per month. This performance may vary based on the hardware specifications of the hosting server.

Software Requirements

User Privilege: In Windows, Administrator privileges required for Applications Manager installation.

Supported Database Backends

Applications Manager supports PostgreSQL and Microsoft SQL database backends for storing all the configuration information and data collected.

Note: Support for Applications Manager with MySQL database was deprecated on March 31,2017. Existing customers can refer to this post for details.

PostgreSQL

  • In Applications Manager versions 17 and higher, the default backend database is PostgreSQL v15. To enable remote PostgreSQL backend in these versions, use PostgreSQL versions 15.5 to 15.x.
  • In Applications Manager versions 16 and earlier, the default backend database is PostgreSQL v11. To enable remote PostgreSQL backend in these versions, use PostgreSQL versions 11.16 to 11.x.
Note: The PGSQL backend has been tested for Applications Manager with cloud services such as AWS RDS and Microsoft Azure PgSQL.

Microsoft SQL

Supported Version: Applications Manager supports the following Microsoft SQL database versions: 64-bit version of Microsoft SQL Servers 2022/ 2019/ 2017/ 2016/ 2014 (SQL Standard / Enterprise Edition).

Authentication: Applications Manager supports mixed mode of authentication (SQL and Windows authentication).

Ports: Default MS SQL database port used is 1433 through TCP.

Note: The MSSQL backend has been tested for Applications Manager with cloud services such as AWS RDS, Azure SQL Server, Azure SQL Managed Instance, and Google Cloud Platform SQL.

The following section lists the various requirements of an MS SQL backend database server for Applications Manager:

 
User-role requirement
  • When creating a new database:
    • Ensure that the user account is part of the dbcreator server role.
  • In the case of utilizing an existing unused database:
    • It is sufficient for the user account to be assigned to the db_owner database role within the existing database.
Note: The user account used for installation must have access to the MASTER databases. Learn more about configuring MS SQL database
 
SQL Server Collation
  • Applications Manager supports any case-insensitive collation setting.
  • Use the following collation settings for respective languages listed below:
    • English with collation setting (SQL_Latin1_General_CP1_CI_AS)
    • Norwegian with collation setting (Danish_Norwegian_CI_AS)
    • Simplified Chinese with collation setting (Chinese_PRC_CI_AS)
    • Japanese with collation setting (Japanese_CI_AS)
    • German with collation setting (German_PhoneBook_CI_AS)
 
SQL AlwaysOn Availability Groups
  • Applications Manager also supports SQL AlwaysOn Availability Groups as database backend.
  • To connect to the SQL AlwaysOn, you will need to provide the SQL availability group's DNS name and listener port (usually 1433) in the place of the database details specified during installation.

Hard Drive Space

Following storage requirements are specifically for the size of SQL datafiles and transaction log files. They do not include requirements for Microsoft SQL installation files, storing SQL backups, etc.

Number of MonitorsMinimum Hard Drive Space
1 to 100 monitors 50 GB
101 to 250 monitors 75 GB
251 to 1000 monitors 100 GB
1001 to 10000 monitors 150 GB
Note:
  • We recommend that you create a separate account for Applications Manager in your MS SQL database server. Learn more about configuring MS SQL database backend for Applications Manager
  • It is recommended that the SQL server is connected to the same LAN as that of Applications Manager.
  • Latency between Applications Manager server and database server should be less than 10 milliseconds.
  • Solid-State Drives (SSD) are strongly recommended.
  • Use SQL Server Express only for evaluations and small environments, such as 10 monitors.
  • From Applications Manager v15000 onwards, Microsoft JDBC driver will be used to establish connection with SQL database server from Applications Manager (except Plugin) by default. However, you can choose between Microsoft JDBC and jTDS JDBC drivers for establishing connection by selecting the required driver under Settings → Server Settings → Database Configuration. For SQL server version 2008 alone, only SQL authentication can be used to establish connection through Microsoft JDBC driver.

Enterprise Edition Limitations

Only Light Load Monitors = 750 Monitors

Only Heavy Load Monitors = 400 Monitors

Medium Load Monitors = 600 Monitors (200 Heavy Load + 400 Light Load)

In Applications Manager, Maximum Load Capacity Per Probe refers to the highest number of monitors or resources that can be efficiently handled by a single probe. It varies based on the probe's configuration, hardware specifications, and the types of monitors being used. The types of monitors that fall within the Heavy Loaded and Light Loaded categories are listed in the following table.
