DataDogLogger

Logger that dumps execution logs to a DataDog service.

Implements: CachedCounters, IReferenceable, IReferenceable

Description

The DataDogLogger class allows you to create loggers that dump execution logs to a DataDog service.

Configuration parameters

  • level: maximum log level to capture
  • source: source (context) name
  • connection:
    • discovery_key: (optional) key to retrieve the connection from IDiscovery
    • protocol: (optional) connection protocol: http or https (default: https)
    • host: (optional) host name or IP address (default: http-intake.logs.datadoghq.com)
    • port: (optional) port number (default: 443)
    • uri: (optional) resource URI or connection string with all parameters in it
  • credential:
    • access_key: DataDog client api key
  • options:
    • interval: interval in milliseconds to save log messages (default: 10 seconds)
    • max_cache_size: maximum number of messages stored in this cache (default: 100)
    • reconnect: reconnect timeout in milliseconds (default: 60 sec)
    • timeout: invocation timeout in milliseconds (default: 30 sec)
    • max_retries: maximum number of retries (default: 3)

References

  • *:context-info:*:*:1.0 - (optional) ContextInfo to detect the context id and specify counters source
  • *:counters:*:*:1.0 - (optional) ICounters components to pass collected measurements
  • *:discovery:*:*:1.0 - (optional) IDiscovery services to resolve a connection

Constructors

Creates a new instance of the logger.

DataDogLogger()

Instance methods

close

Closes a component and frees used resources.

close(correlation_id: Optional[str])

  • correlation_id: Optional[str] - (optional) transaction id used to trace execution through the call chain.

configure

Configures component by passing configuration parameters.

configure(config: ConfigParams)

  • config: ConfigParams - (optional) transaction id used to trace execution through the call chain.

is_open

Checks if the component is open.

is_open(): bool

  • returns: bool - true if the component is open and false otherwise.

open

Opens the component.

open(correlation_id: Optional[str])

  • correlation_id: Optional[str] - (optional) transaction id used to trace execution through the call chain.

_save

Saves log messages from the cache.

_save(counters: List[LogMessage])

  • counters: List[LogMessage] - current counters measurements to be saved.

set_references

Sets references to dependent components.

set_references(references: IReferences)

  • references: IReferences - references to locate the component’s dependencies.

Examples

logger = DataDogLogger()
logger.configure(ConfigParams.from_tuples(
   "credential.access_key", "827349874395872349875493"
))

logger.open('123')
logger.error("123", ex, "Error occured: %s", ex.message)
logger.debug("123", "Everything is OK.")
