Forward CloudWatch logs to Papertrail
Install the library:
go get github.com/m90/papertrailforwarderPackage papertrailforwarder allows for easy creation of AWS Lambda handlers that
forward CloudWatch Log Events to Papertrail.
This is an example of an entire Lambda function:
package main
import (
"fmt"
"github.com/aws/aws-lambda-go/events"
"github.com/aws/aws-lambda-go/lambda"
"github.com/m90/papertrailforwarder"
)
func main() {
handler, err := papertrailforwarder.New(
// the host of the papertrail log target
papertrailforwarder.WithPapertrailHost(<HOST_VALUE>),
// the port of the papertrail log target as an integer value
papertrailforwarder.WithPapertrailPort(<PORT_VALUE>),
// a function that returns a message and whether it should be logged
// it is passed the raw log message as well as the full event
papertrailforwarder.WithMessageTransform(func(message string, event events.CloudwatchLogsLogEvent) (string, bool) {
// prefix all log messages with the event id, forward all messages
return fmt.Sprintf("[%s] %s", event.ID, message), true
}),
)
if err != nil {
panic(err)
}
lambda.Start(handler)
}When invoked without any options, New() will return a handler that uses the
values set in the environment variables PAPERTRAIL_HOST and PAPERTRAIL_PORT
and the unmodified log message will be forwarded.
