After upgrade to v4.0 all graphs are visible at close range only. If zoomed out - graphs disappear, statistics (last, min, avg, max) too.
Example Item: Outgoing traffic on eth2. The item is configured to keep history and trends for 30 days. Video: https://youtu.be/d0twfEPUBM8
EDIT: OK, I found that table trends does not exists.
select * from trends limit 10;
ERROR 1146 (42S02): Table 'zabbix.trends' doesn't exist
Something went wrong during update... I'll try to fix it and import data from backup.
EDIT2: Table restored, data recovered, now everything is OK.
Sorry for the hassle, please close or remove this topic.
