No data on graphs

[ZabCS]

Hi,

I have a Zabbix HA architecture (proxy + servers + MySQL DB)

I cannot visualize data after 7 days and no more than 2 days in a row. For 2 days during a week, it is ok.

I am storing history up to 7d, trends up to 365d in items and all items are overidden by Housekeeping settings (365d)

Have you got an idea :
- How can I solve this issue ?
- How can I troubleshoot it ?

I guess it is a misconfiguration in trends but I cannot find it.

Thank you.

Best regards

I have some new information.

In Monitoring -> Latest Data I select one graph view. Then

- I can see data younger than 2 days.
- Some data between the 15th of August and the 1st of september.

That is all. I do not know what happened in Sepember.

Have you got some idea how could I investigate?

Best regards
