I began to notice that the values ​​disappear on the graphs and after a while it restores itself.

macro in zabbix

{$PHP_FPM_STATUS_URL} = http://127.0.0.1:80/php-fpm_status

If you check through the browser, then the values ​​\u200b\u200bdo not disappear, only on the charts.
Rebutal agent, maybe something else?

Answer 1

Either a value is returned that does not fit zabbix (fractional instead of integer, negative, text), or nothing is returned. Turn on the debug, you will see in the logs what's wrong.
