Log
The github.com/verzth/cosmos-sdk/log provides a zerolog logging implementation for the Cosmos SDK and Cosmos SDK modules.
Documentation
¶
Index ¶
Constants ¶
const ModuleKey = "module"
Defines commons keys for logging
Variables ¶
var ContextKey struct{}
ContextKey is used to store the logger in the context
Functions ¶
func ParseLogLevel ¶
ParseLogLevel parses complex log level A comma-separated list of module:level pairs with an optional *:level pair (* means all other modules).
Example: ParseLogLevel("consensus:debug,mempool:debug,*:error", "info")
Types ¶
type Logger ¶
type Logger interface {
// Info takes a message and a set of key/value pairs and logs with level INFO.
// The key of the tuple must be a string.
Info(msg string, keyVals ...any)
// Error takes a message and a set of key/value pairs and logs with level ERR.
// The key of the tuple must be a string.
Error(msg string, keyVals ...any)
// Debug takes a message and a set of key/value pairs and logs with level DEBUG.
// The key of the tuple must be a string.
Debug(msg string, keyVals ...any)
// With returns a new wrapped logger with additional context provided by a set
With(keyVals ...any) Logger
// Impl returns the underlying logger implementation
// It is used to access the full functionalities of the underlying logger
// Advanced users can type cast the returned value to the actual logger
Impl() any
}
Logger is the Cosmos SDK logger interface It maintains as much backward compatibility with the CometBFT logger as possible All functionalities of the logger are available through the Impl() method
func FilterKeys ¶
FilterKeys returns a new logger that filters out all key/value pairs that do not match the filter. This functions assumes that the logger is a zerolog.Logger, which is the case for the logger returned by log.NewLogger() NOTE: filtering has a performance impact on the logger
func NewCustomLogger ¶
NewCustomLogger returns a new logger with the given zerolog logger.
func NewLogger ¶
NewLogger returns a new logger that writes to the given destination.
Typical usage from a main function is:
logger := log.NewLogger(os.Stderr)
Stderr is the typical destination for logs, so that any output from your application can still be piped to other processes.
func NewLoggerWithKV ¶
NewLoggerWithKV is shorthand for NewLogger(dst).With(key, value).
func NewTestLogger ¶
NewTestLogger returns a logger that calls t.Log to write entries.
If the logs may help debug a test failure, you may want to use NewTestLogger(t) in your test. Otherwise, use NewNopLogger().
type TestingT ¶
type TestingT zerolog.TestingLog
TestingT is the interface required for logging in tests. It is a subset of testing.T to avoid a direct dependency on the testing package.
