Implementation details

• Calls to push method will never throw. Any exception will just be logged using logging.
• Keys in labels and information must be strings. If None is provided as value in case of python, it will be serialized as empty string.
• Values in labels and information must be string, integers or floats.
• If no base_endpoint provided (using parameter or env), nothing will happen.

Configuration

• SMOLOKI_BASE_ENDPOINT – base address of loki server.
• SMOLOKI_HEADERS - headers for request to loki server (can be used for authorization).
• SMOLOKI_BASE_LABELS - base labels that will be added to logs.
• SMOLOKI_BASE_INFORMATION - base information that will be added to logs.
