Calculation expression
(sum(rate(ob_sysstat{stat_id="10005",@LABELS}[@INTERVAL])) by (@GBLABELS) + sum(rate(ob_sysstat{stat_id="10006",@LABELS}[@INTERVAL])) by (@GBLABELS)) / sum(rate(ob_sysstat{stat_id="10000",@LABELS}[@INTERVAL])) by (@GBLABELS)
SQL statements for metric collection
If you use OceanBase Database of a version earlier than V4.0, execute the following statement:
select /*+ MONITOR_AGENT READ_CONSISTENCY(WEAK) */ con_id tenant_id, stat_id, value from v$sysstat where stat_id IN (10005, 10006, 10000) and (con_id > 1000 or con_id = 1) and class < 1000If you use OceanBase Database V4.0 or later, execute the following statement:
select /* MONITOR_AGENT */ con_id tenant_id, stat_id, value from v$sysstat where stat_id IN (10005, 10006, 10000) and (con_id > 1000 or con_id = 1) and class < 1000
