Hi, this should be possible. You would need to create a specific segment for this.
Without knowing how your tagging is, I can really give you a full answer, but I can give an example with our tagging:
For ALL 404 error pages, our "Pages Not Found" dimension will pass a generic name like "404-error", we also track eVars for both "Current URL" (which includes querystring parameters) and "Canonical URL" and a "Page Type". So in my case, I could create a segment where the "Pages Not Found" (or Pages - since these values are the same) is "404-error" AND my canonical URL is my home page url the example for my own website the same things its happened with me at https://mynstromy.com/ (if you don't have that, you might have do use your full url with some rules to try and capture the variations), or where my page type is "home" (some combination that gets me my home page where it's also a 404) -You should test your segment in Workspace to be sure it returns the exact pages you want.
Then when you create your alert, you can set your metric threshold and drag your newly created segment into the filter
Can we set up a page not found (404) alert in Adobe Analytics based on a certain page? For example, let's say we want to set up an alert for homepage 404 if there are more than 50 occurrences. Is that possible?
As long as you can identify the page and that it's a 404 (see what info you are tracking), then yes, you should be able to set up an alert with the specified threshold (50 occurrences)
In Adobe Analytics, you can create an alert for a specific page not found (404) error, such as the homepage. For example, you can set up an alert to DGme Portal notify you if there are more than 50 instances of a 404 error on the homepage. This helps you stay informed about any issues and ensures a better user experience.
The "Page not responding error 404" typically indicates that the webpage you are trying to access could not be found on the server. This error is an HTTP status code that indicates a "Not Found" situation.
Here are a few possible reasons for encountering a 404 error:
Incorrect URL: Double-check the URL you entered to ensure it is correct. Make sure there are no typos or missing characters.
Page or content has been moved or deleted: The webpage you are trying to access may have been moved to a different location or completely removed from the server. Verify if the page still exists by checking the website's navigation or conducting a search on the website.
Broken links: If you encountered the 404 error by clicking a link on another website, the link may be broken or outdated. In this case, you can try searching for the content you're looking for directly on the website or contacting the website administrator to report the broken link.
Server or website maintenance: The server hosting the website may be undergoing maintenance or experiencing temporary issues. In such cases, you can try accessing the webpage later to see if the problem is resolved. Employee Connection
If you are the website owner/administrator, consider checking your server logs and website configuration to ensure that the correct pages are being served and that there are no misconfigured redirects or missing files.
Please note that without specific details about the website or webpage you are referring to, it is challenging to provide a more precise solution.
