指标说明：
1、运行中的计划(runningCount)：
select count(1) from QRTZ_FIRED_TRIGGERS;

2、服务器数量(serverCount):
select count(1) from QRTZ_SCHEDULER_STATE where LAST_CHECKIN_TIME + CHECKIN_INTERVAL > unix_timestamp();

3、每台服务器最大并发数(threadCount):
org_quartz_threadPool_threadCount=10

4、totalCount = serverCount * threadCount
当 runningCount >= totalCount ，超载(waitingCount):

5、待执行(waitingCount)
select count(1) from QRTZ_TRIGGERS where NEXT_FIRE_TIME < unix_timestamp() and TRIGGER_STATE = 'WAITING';
