After update MySQL version from 5.7 to 8.0 I noted a lot of long time queries in mysql which run up to one hour (may be more)
Queries are like this:
SELECT DISTINCT t.triggerid FROM triggers t,functions f,items i WHERE NOT EXISTS (SELECT NULL FROM functions f,items i,hosts_groups hgg LEFT JOIN rights r ON r.id=hgg.groupid AND r.groupid='20' WHERE t.triggerid=f.triggerid AND f.itemid=i.itemid AND i.hostid=hgg.hostid GROUP BY i.hostid HAVING MAX(permission)<'2' OR MIN(permission) IS NULL OR MIN(permission)=0) AND (i.hostid BETWEEN '10210' AND '10214' OR i.hostid BETWEEN '10296' AND '10323' OR i.hostid BETWEEN '10453' AND '10458' OR i.hostid BETWEEN '10461' AND '10508' OR i.hostid BETWEEN '10510' AND '10531' OR i.hostid BETWEEN '10533' AND '10546' OR i.hostid BETWEEN '10549' AND '10564' OR i.hostid BETWEEN '10573' AND '10578' OR i.hostid BETWEEN '10582' AND '10590' OR i.hostid BETWEEN '10598' AND '10604' OR i.hostid BETWEEN '10612' AND '10630' OR i.hostid BETWEEN '10633' AND '10638' OR i.hostid BETWEEN '10640' AND '10646' OR i.hostid BETWEEN '10656' AND '10675' OR i.hostid BETWEEN '10678' AND '10682' OR i.hostid BETWEEN '10698' AND '10702' OR i.hostid BETWEEN '10704' AND '10719' OR i.hostid BETWEEN '10721' AND '10729' OR i.hostid BETWEEN '10741' AND '10748' OR i.hostid BETWEEN '10756' AND '10769' OR i.hostid BETWEEN '10812' AND '10817' OR i.hostid IN ('10181','10208','10219','10220','10221','10246','10257','10261','10262','10263','10292','10293','10294','10325','10326','10334','10366','10367','10368','10380','10381','10394','10405','10406','10569','10570','10571','10606','10607','10608','10609','10648','10649','10650','10651','10684','10685','10696','10732','10773','10774','10781','10785','10787','10788','10789','10793','10794','10795','10797','10798','10799','10800','10803','10833','10861','10862')) AND f.triggerid=t.triggerid AND f.itemid=i.itemid AND NOT EXISTS (SELECT NULL FROM functions f,items i,hosts h WHERE t.triggerid=f.triggerid AND f.itemid=i.itemid AND i.hostid=h.hostid AND (i.status<>0 OR h.status<>0)) AND t.status=0 AND t.flags IN ('0','4')
