资源说明：Go strip your logs before sending them to syslog
# Bark
Pipes and formats lines from stdin to /dev/log and optionally tees the raw output back out to stdout.
Intended to be used with services under daemontools or runit as a log tee with some payload introspection.
This should be able to sustain 100k lines/s, at about 20MB/s.
GC is a concern and the observed latency is about 1ms for a cycle, with a GC cycle happening around every second. For latency sensitive programs that log unbuffered to stdout, please test carefully.
# Usage
Usage of ./gobark:
-delim="\n": the byte sequence that separates events
-ignore-delim=false: exclude the delimiter in each event
-line-buffers=1000: max number of events to buffer
-line-size=4096: expect most events to be shorter than this size
-name="bark": identity/program name that is prefixed to each event
-tee=false: immediately write and block on all reads to stdout
-xpid=false: checks each event for the [x-pid=""] header
Example
./myserver | ./gobark -name myserver -tee > /var/log/myserver
If your program emits lines with the syslog extension `[ x-pid="program" ...`, bark will find it and use `program` as the program name instead of the one passed on the command line.
# Packaging
Run ./deb.bash to build a debian package. This will use the latest discoverable tag as the version.
To tag a new version, use semver:
git tag -a v0.1.1 -m v0.1.1
git push --tags
./deb.bash
# Testing
Build the timings package with `make` then collect and bucket the latencies:
cd timing
make
cd ..
out=samples.out
timing/timing 2>$out | gobark
cat $out | awk '{print int(log($0)/log(10))}' |\
sort -n | uniq -c | awk '{print $2, $1}' | sort -nr
