Cribl LogStream supports receiving raw HTTP data. The Raw HTTP Source listens on a specific port, captures every HTTP request to that port, and creates a corresponding event that it pushes to its configured Event Breakers.
Type: Push | TLS Support: YES | Event Breaker Support: YES
Select Data > Sources, then select Raw HTTP from the Data Sources page's tiles or left menu. Click Add New to open the Raw HTTP > New Source modal, which provides the following fields.
Input ID: Enter a unique name to identify this Raw HTTP Source definition.
Address: Enter the address to bind on. Defaults to
0.0.0.0 (all addresses).
Port: Enter the port number to listen on.
Auth tokens: Shared secrets to be provided by any client. Click Generate to create a new secret. If empty, permits open access.
Enabled defaults to
No. When toggled to
Certificate name: Name of the predefined certificate.
Private key path: Path on server where to find the private key to use in PEM format. Path can reference $ENV_VARS.
Passphrase: Passphrase to use to decrypt private key.
Certificate path: Server path at which to find certificates (in PEM format) to use. Path can reference
CA certificate path: Server path at which to find CA certificates (in PEM format) to use. Path can reference
Authenticate client (mutual auth): Require clients to present their certificates. Used to perform mutual authentication using SSL certs. Defaults to
No. When toggled to
Validate client certs: Reject certificates that are not authorized by a CA in the CA certificate path, or by another trusted CA (e.g., the system's CA). Defaults to
Common name: Regex matching subject common names in peer certificates allowed to connect. Defaults to
.*. Matches on the substring after
CN=. As needed, escape regex tokens to match literal characters. E.g., to match the subject
CN=worker.cribl.local, you would enter:
Minimum TLS version: Optionally, select the minimum TLS version to accept from connections.
Maximum TLS version: Optionally, select the maximum TLS version to accept from connections.
Event Breaker rulesets: A list of event breaking rulesets that will be applied to the input data stream before the data is sent through the Routes. Defaults to
System Default Rule.
Event Breaker buffer timeout: The amount of time (in milliseconds) that the event breaker will wait for new data to be sent to a specific channel, before flushing out the data stream, as-is, to the Routes. Defaults to
In this section, you can add fields/metadata to each event using Eval-like functionality.
- Name: Field name.
In this section's Pipeline drop-down list, you can select a single existing Pipeline to process data from this input before the data is sent through the Routes.
Allowed URI paths: List of URI paths accepted by this input. Supports wildcards, e.g.,
/api/v*/hook. Defaults to
*, which allows all paths.
Allowed HTTP methods: List of HTTP methods accepted by this input. Supports wildcards, e.g.,
P*, GET. Defaults to
*, which allows all methods.
Max active requests: Maximum number of active requests allowed for this Source, per Worker Process. Defaults to
0 for unlimited.
Cribl LogStream uses a set of internal fields to assist in handling of data. These "meta" fields are not part of an event, but they are accessible, and functions can use them to make processing decisions.
