Logs

Use Observability Pipelines’ Socket destination to send logs to a socket endpoint.

Setup

Set up the Socket destination and its environment variables when you set up a pipeline. The following information is configured in the pipelines UI.

Set up the destination

Only enter the identifier for the socket address and, if appliable, the key pass. Do not enter the actual values.
  1. Enter the identifier for your address. If you leave it blank, the default is used.
  2. In the Mode dropdown menu, select the socket type to use.
  3. In the Encoding dropdown menu, select either JSON or Raw message as the output format.

Optional settings

Enable TLS

If you enabled TCP mode, you can toggle the switch to Enable TLS. The following certificate and key files are required for TLS:

  • Enter the identifier for your socket key pass. If you leave it blank, the default is used.

  • Server Certificate Path: The path to the certificate file that has been signed by your Certificate Authority (CA) root file in DER or PEM (X.509).

  • CA Certificate Path: The path to the certificate file that is your Certificate Authority (CA) root file in DER or PEM (X.509).

  • Private Key Path: The path to the .key private key file that belongs to your Server Certificate Path in DER or PEM (PKCS#8) format.

Buffering options

Toggle the switch to enable Buffering Options. Enable a configurable buffer on your destination to ensure intermittent latency or an outage at the destination doesn’t create immediate backpressure, and allow events to continue to be ingested from your source. Disk buffers can also increase pipeline durability by writing logs to disk, ensuring buffered logs persist through a Worker restart. See Configurable buffers for destinations for more information.

  • If left unconfigured, your destination uses a memory buffer with a capacity of 500 events.
  • To configure a buffer on your destination:
    1. Select the buffer type you want to set (Memory or Disk).
    2. Enter the buffer size and select the unit.
      1. Maximum memory buffer size is 128 GB.
      2. Maximum disk buffer size is 500 GB.

Set secrets

These are the defaults used for secret identifiers and environment variables.

Note: If you enter identifiers for your secrets and then choose to use environment variables, the environment variable is the identifier entered and prepended with DD_OP. For example, if you entered PASSWORD_1 for a password identifier, the environment variable for that password is DD_OP_PASSWORD_1.

    • Socket address identifier:
      • References the address to which the Observability Pipelines Worker sends processed logs.
      • The default identifier is DESTINATION_SOCKET_ADDRESS.
    • Socket TLS passphrase identifier (when TLS is enabled):
      • The default identifier is DESTINATION_SOCKET_KEY_PASS.
    • Socket address:
      • The address to which the Observability Pipelines Worker sends processed logs.
      • The default environment variable is DD_OP_DESTINATION_SOCKET_ADDRESS.
    • TLS passphrase:
      • The default environment variable is DD_OP_DESTINATION_SOCKET_KEY_PASS.

    How the destination works

    Event batching

    The Socket destination does not batch events.
