Solved: Re: Splunk dashboard screenshot

jadengoho · ‎07-31-2019

Hi All,
Is there a way to have a screenshot of the dashboard every 5min and save it on a backend folder.
This will be used in HTML picture,

Hi Jadengoho,

Check the below code for implementation of html2canvas in dashboard, (by using onscreen button, you can automate it as per your requirement.
For scheduled screenshot or pdf export you can try Smart PDF app - https://splunkbase.splunk.com/app/4030/

add HTML button on your existing dashboard

<row>
    <panel>
        <html>
            <button id="image_export" class="btn btn-primary">Download ScrenShot</button>
        </html>
    </panel>
<row>

download html2canvas js from - https://html2canvas.hertzen.com
Copy paste html2canvas.js at /appserver/static/component

create a javascript file with below code, and add it in your dashboard (replace with your's)

require([
'underscore',
'jquery',
'splunkjs/mvc',
'splunkjs/mvc/simplexml/ready!',
'../app//components/html2canvas'],

function(_, $, mvc,html2canvas) {

$("#image_export").on('click',function(e){
    var screenshot = require("../app/<app_name>/components/html2canvas");

    screenshot(document.querySelector('#dashboard1'), {scale:2}).then(canvas => {
        console.log(canvas);

        var image = canvas.toDataURL("image/png").replace("image/png", "image/octet-stream");

        var link = document.createElement('a');
        link.download = "Dashboard Report.png";
        link.href = image;
        link.click();
    });
});

});

@gaurav_maniarthe below code is not working..Does it depend on Splunk version?

require([
'underscore',
'jquery',
'splunkjs/mvc',
'splunkjs/mvc/simplexml/ready!',
'opt/splunk/etc/apps/screenshot/appserver/static/components/html2canvas'],
function(_, $, mvc,html2canvas) {

$("#image_export").on('click',function(e){
    var screenshot = require("opt/splunk/etc/apps/screenshot/appserver/static/components/html2canvas");

    screenshot(document.querySelector('#test1'), {scale:2}).then(canvas => {
        console.log(canvas);

        var image = canvas.toDataURL("image/png").replace("image/png", "image/octet-stream");

        var link = document.createElement('a');
        link.download = "Dashboard Report.png";
        link.href = image;
        link.click();
    });
  });
});

@jadengoho

You can use HTML screen capture javascript libraries for same. You need to code in javascript that takes a screenshot. Integrate that Javascript code with your respective dashboard. Make sure your javascript code execute every 5 minutes ( as per your requirement).

You need to create another code which sends your screen to your server and store into your desired folder. You have to write code for that in above Javascript code.

Below are some links for reference.
