Your Cloud Run application writes unstructured logs as text strings to Cloud Logging. You want to convert the unstructured logs to JSON-based structured logs. What should you do?
A.
Modify the application to use Cloud Logging software development kit (SDK), and send log entries with a jsonPayload field.
B.
Install a Fluent Bit sidecar container, and use a JSON parser.
C.
Install the log agent in the Cloud Run container image, and use the log agent to forward logs to Cloud Logging.
D.
Configure the log agent to convert log text payload to JSON payload.
- Cloud Logging supports structured logging by using the jsonPayload field, which allows you to log data in JSON format.
- Modifying the application to log in a structured JSON format ensures that the logs are parsed correctly by Cloud Logging without additional processing.
Why not D?
Configuring a log agent to convert logs from text to JSON adds unnecessary overhead. If you control the application, it's better to directly emit logs in structured JSON format using the SDK.
Why not B?
Using a Fluent Bit sidecar container can parse logs, but it introduces complexity. Fluent Bit is better suited for parsing logs in environments where you cannot control the log output of the application (e.g., legacy systems).
Why not C?
Installing a log agent (such as Fluentd) within the Cloud Run container is not recommended. Cloud Run is designed to be stateless, and using log agents within the container image increases management overhead and resource consumption.
Vote option D.
In this context, if you have unstructured logs written as text strings and want to convert them to JSON-based structured logs, you would typically use a log agent or parser to transform the log entries. The log agent is configured to recognize the structure of the logs and convert the text payload into a JSON payload.
The log agent would be responsible for parsing the unstructured logs and converting them into a structured format. This process involves specifying how to extract relevant information from the text payload and organize it into a JSON structure. It's important to note that this approach assumes you have a log agent or parser that supports the transformation of unstructured logs to structured logs.
The Cloud Logging agent can be configured to convert log text payload to JSON payload by setting the process.payload parameter to json. This will cause the agent to parse the log text and convert it to a JSON object before forwarding it to Cloud Logging.
