Query most triggered items
SELECT DISTINCT `history_uint`.`itemid`, count(`history_uint`.`itemid`) AS CountOf, `items`.`itemid`, `items`.`name` FROM `history_uint` LEFT JOIN `items` ON `history_uint`.`itemid` = `items`.`itemid` GROUP BY `history_uint`.`itemid` ORDER BY CountOf DESC
Configuration
Host name
{psl}.{ber|dus}.{ns125|rds26}.{vh|hh|fb|hh|...}.{ug|eg|1og|...}.{kind e.g. vserver}.{machine name, e.g. pslsrv32}. Example:
psl.dus.ns125.fb.1ug.vserver.pslsrv15
Visible name
{PSL} | {BER|DUS} | {NS125|RDS26} | {VH|HH|FB|HH|...} | {UG|EG|1OG|...} | {kind e.g. vServer} | {machine name, e.g. PSLSRV15} ({Short Description}). Example:
PSL | DUS | NS125 | FB | 1UG | vServer | PSLSRV15 (Preview Webserver)
