tinymonit

collect the cpu & mem information from the specified machine(remote or local), supports cluster mode which gather all stats from config list!

Feature list

• promisify function
• gather system cpu usage
• gather system mem usage
• gather specified process cpu & mem usage
• judge if over the threshold
• support cluster mode

Install

$ npm install tinymonit -g

Usage

Get os stat

const tm = require('tinymonit');
const osstat = tm.osstat;

Promise.resolve()
.then(() => osstat([8122]))
.then((stat) => console.log(r));

create a part

const Part = require('tinymonit').part;

let part = new Part(3000, {
    timeout: 100,
    pid: process.pid // this is defalut
});

create a central

const Central = require('tinymonit').central;

let ctl = new Central({
    timeout: 100,
    parts:[
        3000,
        [3001, 200]
        //'[remote ip]:[port]'
    ]
});

// start collect performance data from 3000, 3001
Promise.resolve()
.then(() => ctl.collect())
.then((allstats) => {
    // do sth
});

alarm when over threshold from cpu, mem etc.

const tm = require('tinymonit');
const pid = process.pid;
const osstat = tm.osstat;
const alarm = tm.alarm;

Promise.resolve()
.then(() => osstat([pid]))
.then((stat) => {
    console.log(alarm.should_cpu_alarm(rstat, 1));
    console.log(alarm.should_mem_alarm(stat));
    console.log(alarm.should_load_alarm(stat));
    console.log(alarm.should_procs_alarm(stat, 2));
});

Examples

• get process stat
• get system stat
• use alarm
• cluster mode

if you wanna debug, just execute $ DEBUG=* node example.js to enable debug.
