Im using zabbix 6. In the previous versions we could select historical data from the last month and show this in a Graph, see photos. In version 6 I still can select all time periods (say last year, last month, last weak, today,etc). But the only time a graph is shown is when i select a time period shorter than 5d 4h 26m. When I read the manual of zabbix 6 there were some changes in the graphs. But the interface is strange, why can I select time ranges but no data is displayed??

Even if you can specify a time range, if the item's history and trend data are not saved, you will not be able to display the graph for that period. For example, a new item created this week doesn't have a value and doesn't show a graph because it wasn't there last week. The same applies when the storage period of history and trend data is short. -
I solved the problem. Previously we worked with partitioning with mysql. We removed this while we upgraded to zabbix6. But not all references were removed so zabbix couldn't write to the trend tables anymore. We removed the tables and created them again and the problems were solved.Comment
