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:

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/`	`%ProgramFiles%\` `dynatrace\gateway\`	ActiveGate core logs: dynatracegateway.log dynatracegateway_Debug.log rejections.log audit.log	Environment ActiveGate & Cluster ActiveGate	300 MB
`/var/log/` `dynatrace/` `synthetic/log/`	`%ProgramData%\` `dynatrace\` `synthetic\log\`	HTTP checks/Synthetic logs: engine logs engine installation logs engine wrapper logs player logs	Environment ActiveGate & Cluster ActiveGate	1 GB
`/var/lib/` `dynatrace/` `remotepluginmodule/` `log/`	`%ProgramData%\` `dynatrace\` `remotepluginmodule\` `log\`	Remote Plugin Module logs	Environment ActiveGate only	500 MB
`/var/log/dynatrace/zremote/log`	`%ProgramData%\` `dynatrace\` `zremote\` `log\`	ZRemote logs	Environment ActiveGate & Cluster ActiveGate	200 MB

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

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=
```

¹Starting with ActiveGate vesion 1.183

ActiveGate installation isn't supported on Windows with a disabled NT AUTHORITY\LocalService account.
