Zabbix brower item : screenshot function doesn't wait for the page to be fully loaded

[ThomasP]

Hello,
We are trying to use the "Website by browser" template to monitor internal web applications.

We have an issue with one of our applications : loading the page including data (loaded by Javascript) takes some time and Zabbix is only able to a take a screenshot of an empty page (before data got loaded).
See screenshot below :

Is there a way to tell Zabbix to wait some data to be available before taking a screenshot.

Thank you

Thomas

Hello,
According to https://www.reddit.com/r/zabbix/comm...wbrowser_item/, it looks like there is no way to delay the screenshot.
Has anyone played with this feature ?
Thank you

Hello,

You can add this code to delay the screenshot :


function sleep(ms) {
const end = Date.now() + ms;
while (Date.now() < end) { }
}
sleep(5000);



Best regards,
STGA.

Hello Thomas.
I faced the same problem. The solution I found was to add a function to only send the data (JSON) when the script encounters an item that only appears at the end of the page load. For example: my page being monitored has a logo (JPEG), which only appears at the end of the page load. I created a function within the script that only sends the data to Zabbix when this image appears. It's simple; with the help of some artificial intelligence, you can solve it, even if you don't have JavaScript experience.
