I would recommend you update your code to use the above patch. The reason for text string is to make it clear that there was no previous runtime available. Thanks for report it.

1. I perfectly understood "never" was intended to mark ' no previous runtime available'
2. round function is complaining/crashing about it (when no previous runtime available)
3. this part of cacti code is 6 year old and never got trouble about it, but now with php-8 "round" fonction is
   complaining
4. I am using 1.2.16, poller.php code is still the same within 1.2.17
5. Sorry, But whereis the "above patch", what am I missing here?

If you look, there is a commit a2febc0 that was applied and github listed above. Thanks for clearing up that PHP 8 is now erroring on string rounding (which is right). We may start to see other reports fall in.
