ActiveGate default installation settings for Linux

If you do not specify any parameters during ActiveGate installation to customize settings, the following default settings will be applied. To modify defaults settings during installation, see Customize ActiveGate installation on Linux.

Directories

Purpose of directory	Default path Path relative to installation parameter	Disk space requirements (if size is not given, assume less than 1 MB)
ActiveGate executable files, libraries, and related files	`/opt/dynatrace/gateway` `<INSTALL>/gateway`	300 MB
ActiveGate configuration	`/var/lib/dynatrace/gateway/config` `<CONFIG>/gateway/config`
ActiveGate SSL folder	`/var/lib/dynatrace/gateway/ssl` `<CONFIG>/gateway/ssl`
ActiveGate temporary files	`/var/tmp/dynatrace/gateway` `<TEMP>/gateway`	4 GB (including 3 GB for cached OneAgent installers and container images)
ActiveGate logs	`/var/log/dynatrace/gateway` `<LOG>/gateway`	500 MB
Dump files uploaded to ActiveGate by OneAgent	`/var/lib/dynatrace/gateway/dump`	Functionality off by default. When activated, can take configurable maximum size: default 100 GB.
ActiveGate packages directory for auto-update installer downloads	`/var/lib/dynatrace/packages` `<PACKAGES_DIR>`	500 MB.
ActiveGate Extensions 1.0 and Extensions 2.0 executable files, libraries, and related files	`/opt/dynatrace/remotepluginmodule` `<INSTALL>/remotepluginmodule`	350 MB
ActiveGate Extensions 1.0 and Extensions 2.0 configuration, logs, cache, run-time work area	`/var/lib/dynatrace/remotepluginmodule` `<CONFIG>/remotepluginmodule`	2 GB (for logs and crash dumps)
ActiveGate extensions upload directory	`/opt/dynatrace/remotepluginmodule/plugin_deployment/`	Depending on uploaded extensions
zRemote executable files, libraries, and related files	`/opt/dynatrace/zremote` Using non-default directories is not supported.	50 MB
zRemote user-modifiable persistent configuration, zRemote runtime work area, crash reports	`/var/lib/dynatrace/zremote/agent` Using non-default directories is not supported.	50 MB
zRemote logs	`/var/log/dynatrace/zremote/log` Installing ActiveGate with zRemote in non-default directories is not supported.	200 MB
Private Synthetic executable files, libraries, and related files	`/opt/dynatrace/synthetic` `<INSTALL>/synthetic`	270 MB
Private synthetic logs	`/var/log/dynatrace/synthetic` `<LOG>/synthetic/log`	1 GB
Private Synthetic temporary files	`/var/tmp/dynatrace/synthetic`	20 GB, including 1 GB for the `/var/tmp/dynatrace/synthetic/cache` and 1 GB for `/var/tmp/dynatrace/synthetic/screenshots` You can use `TEMP` to customize this location; however, for Synthetic-enabled ActiveGate installed on Ubuntu 20.04 LTS and 22.04 LTS, the path must begin with `/var/tmp`, for example, `TEMP=/var/tmp/syn`. Dynatrace requires write access to `/var/tmp` for the installation of Chromium snap packages.
Autoupdater	`/opt/dynatrace/autoupdater` `<INSTALL>/autoupdater`	Included in estimate for ActiveGate executable files
Autoupdater logs	`/var/log/dynatrace/autoupdater` `<LOG>/autoupdater`	200 MB
