Techniques to Monitor Queries and ETL Load
CPU and Disk I/OSelect username, processor, sum(cputime), sum(diskio) from dbc.ampusage where processor ='1-0' order by 2,3 descgroup by 1,2;UserName Vproc Sum(CpuTime) Sum(DiskIO)AC00916 10 6.71 24975
List Hardware ErrorsThere is a possibility that the system might have adequate disk space but out of free cylinders. In order to monitor hardware errors, the following query was used:Select * from dbc.Software_Event_Log where Text like '%restart%' order by thedate, thetime;For active users, usage of CPU and analysis of bad CPU to I/O ratiosSelect * from DBC.AMPUSAGE where username='CRMSTGC_DEV_ID'; AND SUBSTR(ACCOUNTNAME,6,3)='006';
