Overview ¶
Package log implements logging for the datadog agent. It wraps seelog, and supports logging to multiple destinations, buffering messages logged before setup, and scrubbing secrets from log messages.
Compatibility ¶
This module is exported and can be used outside of the datadog-agent repository, but is not designed as a general-purpose logging system. Its API may change incompatibly.

Types ¶
type DatadogLogger ¶
type DatadogLogger struct {
// contains filtered or unexported fields
}
DatadogLogger wrapper structure for seelog
type KlogRedirectLogger ¶ added in v0.44.0
type KlogRedirectLogger struct {
// contains filtered or unexported fields
}
KlogRedirectLogger is used to redirect klog logs to datadog logs. klog is client-go's logger, logging to STDERR by default, which makes all severities into ERROR, along with the formatting just being off. To make the conversion, we set a KlogRedirectLogger as klog's output, and parse the severity and log message out of every log line. NOTE: on klog v2 this parsing is no longer necessary, as it allows us to use kSetLogger() instead of kSetOutputBySeverity(). unfortunately we still have some dependencies stuck on v1, so we keep the parsing.
func NewKlogRedirectLogger ¶ added in v0.44.0
func NewKlogRedirectLogger(stackDepth int) KlogRedirectLogger
NewKlogRedirectLogger creates a new KlogRedirectLogger with provided stack depth
