General Settings

Outpost Group Configuration

You can configure the following general Outpost Group options on the Overview tab:

Outpost Group Configuration SettingDescription
DescriptionOptionally, add or edit the Outpost Group description.
TagsUse tags to organize Outpost Groups into logical categories.
Time to keep disconnected OutpostsConfigure how long the Outpost Group should retain information about an Outpost that disconnects from the Leader. Format examples: 8h, 5d, 1w (format defaults to days if you only specify a number). Default: 1 day.

Proxy Settings

Use proxy env vars: Honors the HTTP_PROXY/HTTPS_PROXY environment variables. Defaults to toggled on.

Cribl prioritizes environment variables for proxy settings in this order: Process, User, and System.

If your Cribl service is managed by a service manager other than systemd (such as upstart or init), the Use proxy env vars toggle might not behave as expected because Cribl might prioritize environment variables set by the service manager instead of using the proxy settings you intended.

Limits

The Limits tab provides access to controls for metrics, storage, metadata, jobs, the Redis cache and connections to it, and CPU settings.

Metrics

Storage

Min free disk space: The minimum amount of disk space on the host before various features take measures to prevent disk usage (KB, MB, and so on). Default: 5 GB. To avoid the “Unable to write to the filesystem, disk space low” error, ensure that the available disk space remains above this threshold by monitoring disk usage and configuring alerts.

Metadata

Event metadata sources: List of event metadata sources to enable. No sources are enabled by default.

SNI

Disable SNI-based connection routing: This setting affects how the Cribl control plane routes connections.

Do not change this setting without consulting Cribl Support first.

Support

Support SettingDescription
Feature Flag OverridesCribl thoroughly tests all releases in Cribl.Cloud environments to ensure stability and reliability. However, new features can sometimes behave unpredictably in customer-managed data environments. The scale of some environments and the complexity of many possible configurations make it difficult to test for every possible scenario, occasionally leading to unforeseen issues.

To ensure the stability of your production environment, Cribl Stream includes a safety mechanism that makes it possible to disable specific new features if they are causing unexpected issues. This is a customer-first tool designed to minimize impact and avoid the need to rollback upgrades or wait for a full patch release.

If you suspect that a new feature is impacting your environment, please contact the Support team for assistance. This process ensures that Cribl can quickly stabilize your environment while also collecting the necessary information to improve Cribl Stream for everyone.

Do not change this setting without consulting Support first.
Log file max sizeMaximum size of each log file before rotation. Enter a numeral with units of KB or MB (for example, “5 MB”, “1024 KB”). Default: 5 MB. Minimum: 1 MB.
Number of log files to keepNumber of rotated log files to keep before purging. Default: 5. Range: 1-100. Only new rotations use this limit. Existing files above the previous limit are not removed.

Distributed Settings

Listener Settings

Listener SettingDescription
AddressThe hostname or IP address you want to bind the API server to.
PortAPI port to listen to.
IP allowlist regexRegex matching IP addresses that are allowed to establish a connection.

TLS Settings

For information on TLS options, see the documentation for any Source or Destination that supports TLS.

Service Process

Services

Number of connection listener processes: The number of Outpost connection listeners to spawn. Positive numbers specify an absolute number of listeners. Negative numbers specify a number of listeners relative to the number of CPUs in the system. The default is -2.

Other Settings

This page’s remaining options work essentially the same way as their counterparts in Settings > Global. Use the following links for details about logging levels/redactions and security.
