About logr

Logr is an open-source logger and metric service.

Logger

Pretty simple and nice looking logger that looks just like your terminal. Which allows you to navigate equally well in both the production server terminal and the logger interface. Logr provides easy search by date patterns instead of cumbersome date pickers. Also search by log level, commit version and hostname. And of course search by regular expression with highlighting of found fragments.

Metrics

It is often convenient to use metrics instead of logging. Logr provides this option as well.
Track the execution time of your feature and view it on a graph.
Explore the percentage of cache hits to monitor its efficiency.
Finally graph the amount of RAM or disk space on the server with your application.
If you have a high-load application, it is not convenient to use logs because of the huge number of them, then metrics become indispensable.

Usage

docker run -d -p 7776:7776/udp -p 7778:7778 --name logr kozhurkin/logr

const { Logr } = require('logr-node-client');

const conf = new Logr({
  udp: ':7776',
  publicKey: 'MCAwDQYJKoZIhvcNAQEBBQADDwAwDAIFAMg7ICAwEAAQ==',
  privateKey: 'MC0CAQACBQDIOyKzAgMBAAECBQCHaZAgMA0nkCAwDziw=',
});

const logr = conf.newLogger('hello.log');

logr.info('Hello, Logr!');

// 2024-01-30T22:50:04+03:00 info [v1.0.41, pid=60512, cmd/hello.go:41] Hello, Logr!
