ActiveGate hardware and system requirements

This topic explains the hardware and operating system requirements for installing ActiveGate.

Synthetic-enabled ActiveGates support a subset of operating systems. See System and hardware requirements for synthetic-enabled ActiveGates.

Hardware requirements

You need a machine dedicated to ActiveGate that has:

  • 2 GB free disk space
  • 2 GB RAM (4 GB recommended)
  • 1 dual core processor

For large environments, you may need to use a machine with additional CPU and memory.

We recommend

For optimal performance, we strongly recommend that you install and run the ActiveGate on a dedicated system.

The 2 GB free disk space includes minimum space for specific log directories:

Linux Default Path Windows Default Path Description ActiveGate Minimum disk space
/var/log/

dynatrace\gateway\ 		ActiveGate core logs:

Synthetic-enabled ActiveGates are more demanding in terms of hardware requirements. See System and hardware requirements for synthetic-enabled ActiveGates.

System requirements

  • Ensure that you have proper network port configuration.
  • ActiveGate supports only operating systems running on the x86-64 architecture (64-bit Intel/AMD).

Linux requirements

  • Your operating system must handle at least 500,000 open files for the dtuserag user.
    To view the system limit, execute the following command:

    [user@host]# cat /proc/sys/fs/file-max

    Also, it may be that you've checked out too many open files in Linux.

  • Your operating system must have at least 20,000 processes available to the dtuserag user.
    To view the system limit, execute the following command:

    [user@host]# cat /proc/sys/kernel/pid_max

  • The ActiveGate Linux installer doesn't support ACL (Access Control List). ACL rules may prohibit access to installer-created directories and files, making the ActiveGate fail to start. If you use the ACL, rules related to the installation directories defined in the following parameters should be disabled:

    INSTALL=  
CONFIG=  
LOG=  
TEMP=  
PACKAGES_DIR=

Supported Linux distributions

Sizing guide

The following table represents the machine instance size requirement based on number of OneAgents communicating with the ActiveGate. On each host, OneAgent is performing seven monitoring tasks:

  • Infrastructure monitoring
  • Log monitoring
  • Full-stack monitoring of 3 Apache Tomcat instances
  • Full-stack monitoring of 2 Apache HTTP Server instances
Machine size Number of hosts Number of agents on one host
c4.large 450 7
c4.xlarge 900 7
c4.2xlarge 1200 7

The C4 machine instances included in the estimates:

Instance vCPU Mem (GiB) Storage Dedicated EBS bandwidth (Mbps) Network performance
c4.large 2 3.75 EBS-Only 500 Moderate
c4.xlarge 4 7.5 EBS-Only 750 High
c4.2xlarge 8 15 EBS-Only 1,000 High
