After truncate zabbix history-related tables
I truncated history-related tables for zabbix database cleaning.
After truncating the history-related tables, the data that was previously displayed correctly on the dashboard appeared as "no data."
This issue did not occur on all dashboards, but occurred intermittently on some items on some dashboards.
Even after updating the settings of the problematic item, the issue persisted.
And when I checked again the following day, the previously missing data was displayed normally.
1. I'm curious about the reason why data didn't appear immediately after truncating the history-related tables and only showed up about a day later.
2. When I need to truncate a history-related tables again, I hope that new data can be collected and displayed immediately. What should I do to do that?
