Learn about the limitations and requirements of ActiveGate plugins.
Supported ActiveGate types
ActiveGate plugins are executed by an Environment ActiveGate. Note that you can't execute ActiveGate plugins using an Environment ActiveGate that's configured for multi-environment support.
The ActiveGate plugin module limits the amount of data sent to Dynatrace Server.
The data is trimmed after reaching the limit, but all the data up to the limit is still sent. For some entities, the plugin module raises an exception when the limit is reached. The exception is displayed in Settings > Monitoring > Monitored technologies for a related plugin.
The table below presents the entities where limits apply, along with the maximum values.
|Groups||Number of device groups created per minute, per endpoint||50||Yes|
|Group Properties limit||Maximum number of custom properties reported per process group, custom device group||1||No|
|Devices||Number of devices created per minute, per endpoint||500||Yes|
|Properties limit||Maximum number of custom properties reported per host, process group instance, custom device||5||No|
|Property value length||Length of custom property value string||200||No|
|Property key length||Length of custom property key string||100||No|
|Measurements limit||Number of metrics including dimensions per minute, per endpoint||100 000||Yes|
|Events limit||Number of events per minute, per endpoint||100||Yes|
|Event title length||Length of event title string||1 024||No|
|Event description length||Length of event description string||10 240||No|
Filtering metrics, problems, and events
Remember there are several filtering systems. Custom metrics and events are limited by quotas. If ActiveGate module quotas are in use, you'll find this information in the Remote Plugin Module logs.
Naming Python plugin files
All plugins are written in Python. Because of how Python works, there may be ambiguities when Python uses
import statements. Namely, if there are multiple plugins using files that are identically named, there may be issues importing those files. Because of this, you should use unique file names that are unlikely to appear in other plugins. For example, instead of a generic file name like
utils.py, use something like
