noto-time

Super simple time logging module to save measured times to a database

noto-time will save each entry with how much time it took to execute, an id, a service id and whatever meta data you need. It also gives you the ability to pause a timer, in case you want to measure something that shouldnt include a sub task.

noto-time will bulk save entries to the database at a given interval to save performance.

This module was created 2018-03-15 so its very very alpha.

How to use:

const notoTime = require('noto-time');

// Pass a connection uri in this format: postgres://foo:foobarbaz@db/noto. More info on this further down.
const noto = notoTime({connectionUri: process.env.DB_CONNECTION_URI}, service: 'noto-test', meta: {});

// This is a normal timer with an identifier
let timer = noto.start('normal-timer');

// This should save about 500 ms
setTimeout(() => {

    // End the timer like this
    timer.end();

}, 500);

With pause

const notoTime = require('noto-time');

// Pass a connection uri in this format: postgres://foo:foobarbaz@db/noto. More info on this further down.
const noto = notoTime({connectionUri: process.env.DB_CONNECTION_URI}, service: 'noto-test', meta: {});

// This should save about 1000 ms, but total execution time should be about 1500 ms,
// bacause it pauses the timer

let timerWithPause = noto.start('with-pause');
setTimeout(() => {
    timerWithPause.pause();
    setTimeout(() => {
        timerWithPause.continue();
        setTimeout(() => {
            timerWithPause.end();
        }, 500);
    }, 500);
}, 500);

Options

noto-time can be initialized with some options:

const noto = notoTime(options);

where options is an object with the following keys:

{
    connectionUri: [connection uri],    // Db connection string
    service: [string],                  // defaults to 'noto-test'. Name of the service
    meta: [object],                     // defaults to {},
    maxTimeout: [integer],              // Max time to log in miliseconds. Defaults to 30000. If the elapsed time is more than this value, we will ignore it.
    saveTimeout: [integer],             // How often it should save to the database in ms. Defaults to 5000,
    enabled: [boolean],                 // Defaults to true. This can be set to false and noto-time will not log anything. It exists so you can have measurements
                                        // that might be turned off in production

}
