p4logtail

This utility is part of p4prometheus and will continuously tail a p4d log file, writing completed commands in JSON format to an output file.

Uses go-libp4dlog for actual log file parsing.

It is intended to provide a simple way to export commands to Elastic Search and similar tools.

Overview

This can be run as a spawned process or packaged up via systemd

Configuration

The config file is by default p4logtail.yaml:

# p4_log: the p4d log file, e.g. SDP would be /p4/1/logs/log
# This file can be rotated without issue
p4_log:     /p4/1/logs/log
# json_log: the output JSON file containing one line per completed command.
# Can also be rotated together with the p4_log
json_log:   /p4/1/logs/log.json

Running the process

$ ./p4logtail -h
usage: p4logtail [<flags>]
