Lumberjack Redis Device

This is a simple reference implementation of a device for the lumberjack to send logs to a data store.

Warning

This gem is not intended for high volume production use. It is intended to be a simple way to expose a smallish volume of logs from a remote system via Redis.

In a high traffic system, the logs will roll over too quickly to be useful.

It can be useful as a temporary store in log shipment, or as a debug tool for seeing only recent log entries.

The number of entries in the list can be capped with the :limit paramter on the constructor. An expiration time can also be set on the redis key as well with the :ttl parameter.

# create a device to save to the app.log key in redis
# with a limit of 1000 entries that expires one hour after the last write.
device = Lumberjack::RedisDevice.new("app.log", redis: Redis.new, limit: 1000, ttl: 3600)

The log entries can then be read out again with the read method. The result will be an array of Lumberjack::LogEntry objects in the reverse order that they were written in (i.e. newest first).

entries = device.read
