Monitor high disk usage in your NodeJs application

Monitor high disk usage in your NodeJs application

When building NodeJs applications, we often end up dealing with persistent data in one way or another. This can be a simple JSON, CSV, or text file on disk, uploading files to cloud storage such as S3 or Google Cloud Storage, or even storing data in a database such as MongoDB or MySQL. In all of these cases, disk usage is a critical aspect of our NodeJs application and can significantly affect the user experience.

Therefore, monitoring our NodeJs application's disk usage is essential, whether in the local environment or somewhere in the cloud. This is critical as going over a certain threshold can cause our application to crash or become unavailable, resulting in a significant loss of revenue and user experience.

LogSnag is a powerful event tracking tool that works seamlessly with NodeJs and makes it trivial to track any important event in our NodeJs application in real time. For example, one common use case for LogSnag is tracking disk usage in real-time and setting up rules to notify our team and us when our disk usage has exceeded a certain threshold. This way, we can always be aware of the performance of our application and take immediate action if needed.


Setting up LogSnag

  1. Sign up for a free LogSnag account.
  2. Create your first project from the dashboard.
  3. Head to settings and copy your API token.

NodeJs code snippets

Use the following code to connect LogSnag to your NodeJs application and track disk usage: Please replace the YOUR_API_TOKEN with your API token and update the project and channel names.

Using NodeJs with Axios
const axios = require('axios');
let data = JSON.stringify({
"project": "my-saas",
"channel": "status",
"event": "High Disk Usage",
"description": "The disk usage is high.",
"icon": "💾",
"notify": true
});

let config = {
method: 'post',
maxBodyLength: Infinity,
url: 'https://api.logsnag.com/v1/log',
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer YOUR_API_TOKEN'
},
data : data
};

axios.request(config)
.then((response) => {
console.log(JSON.stringify(response.data));
})
.catch((error) => {
console.log(error);
});
Using NodeJs with Native
var https = require('follow-redirects').https;
var fs = require('fs');

var options = {
'method': 'POST',
'hostname': 'api.logsnag.com',
'path': '/v1/log',
'headers': {
'Content-Type': 'application/json',
'Authorization': 'Bearer YOUR_API_TOKEN'
},
'maxRedirects': 20
};

var req = https.request(options, function (res) {
var chunks = [];

res.on("data", function (chunk) {
chunks.push(chunk);
});

res.on("end", function (chunk) {
var body = Buffer.concat(chunks);
console.log(body.toString());
});

res.on("error", function (error) {
console.error(error);
});
});

var postData = JSON.stringify({
"project": "my-saas",
"channel": "status",
"event": "High Disk Usage",
"description": "The disk usage is high.",
"icon": "💾",
"notify": true
});

req.write(postData);

req.end();
Using NodeJs with Request
var request = require('request');
var options = {
'method': 'POST',
'url': 'https://api.logsnag.com/v1/log',
'headers': {
'Content-Type': 'application/json',
'Authorization': 'Bearer YOUR_API_TOKEN'
},
body: JSON.stringify({
"project": "my-saas",
"channel": "status",
"event": "High Disk Usage",
"description": "The disk usage is high.",
"icon": "💾",
"notify": true
})

};
request(options, function (error, response) {
if (error) throw new Error(error);
console.log(response.body);
});
Using NodeJs with Unirest
var unirest = require('unirest');
var req = unirest('POST', 'https://api.logsnag.com/v1/log')
.headers({
'Content-Type': 'application/json',
'Authorization': 'Bearer YOUR_API_TOKEN'
})
.send(JSON.stringify({
"project": "my-saas",
"channel": "status",
"event": "High Disk Usage",
"description": "The disk usage is high.",
"icon": "💾",
"notify": true
}))
.end(function (res) {
if (res.error) throw new Error(res.error);
console.log(res.raw_body);
});
