Grafana 30day NO date


7day data is ok


30day No data

why?
Please help thanks

ps.
It can be displayed for two days before, but it cannot be displayed for 7 days. After modifying httpd/zabbix.conf, it can be displayed for 7 days.

But I still can’t see it for 30 days
The same is true for increasing memory_limit

Welcome to the forum.

I have to ask the obvious question: Are you sure that you certain that the data exists in your source before 11/18 or so?

sorry
Check zabbix to make sure there is no more than 7 days of data
How do I need to change zabbix?

Are you stating that you need to change Zabbix to go back more than 7 days? I have never used Zabbix, but it sounds like your question is more of a Zabbix question than a Grafana question. Maybe try their forum?
