Problems that log-shuttle solves:
- Remove Syslog dependency between user process & Logplex.
- Improve cross-datacenter security model.
- More control over backpressure.
# Assuming Go1. $ go get github.com/ryandotsmith/log-shuttle $ cd $GOPATH/src/github.com/ryandotsmith/log-shuttle $ go build
$ export LOGPLEX_URL=https://logplex.com $ # or with basic auth creds which will be used for HTTP requests: $ export LOGPLEX_URL=https://user:firstname.lastname@example.org
Connect Via UNIX Socket
$ ./log-shuttle -logplex-token="123" -socket="/tmp/log-shuttle" $ echo 'hi world\n' | nc -U /tmp/log-shuttle
Connect Via STDOUT
$ echo 'hi world\n' | ./log-shuttle -logplex-token="123"
Run the following command for available flags:
$ log-shuttle -h
log-shuttle uses this flag's value to inflate each log's headers with the token, which serves as an identifier of the source of the log message. If the
LOGPLEX_URL does not contain a username or password, this value is also used as the HTTP Basic Auth password.
There are certain cases in which you would not want log-shuttle to prepend log messages with the rfc5424 approved headers. By using the
skip-headers flag, log-shuttle will not prepend headers before submitting the logs to logplex. If you are skipping headers, please ensure that you have the logplex token included in the headers.
The front buffer holds lines while the backend sends them to logplex. If log-shuttle receives large amounts of data with a small front-buff, log-shuttle will drop data. The number of dropped lines will be visible in log-shuttle's STDOUT.
The backend routine that delivers log lines to logplex will execute if the front-buff is full or on a timed schedule --whichever occurs first. The timer is configurable by the wait flag.
The batch-size determines how many rfc5424 formatted log-lines to pack into an HTTP request.
l2met is a service that will convert log lines into librato metrics. You can point log-shuttle at an l2met service for maximum log leverage. Just set LOGPLEX_URL to your l2met drain URL.
