Oracle: compare DB Time and CPU time to ASH
April 26th, 2019
Below I’m comparing AAS from ASH verses SYSMETRICs specificially
- ASH CPU in AAS vs SYSMETRIC CPU in AAS
- ASH total AAS vs SYSMETRIC total AAS derived from DB TIME
ASH CPU is consistently lower that SYSMETRIC CPU and that could be because waits burn CPU but show up as waits and not CPU in ASH.
On the other hand, not sure why total AAS from SYSMETRIC is consistently smaller than total AAS from ASH.
Def v_secs=60 -- bucket size
select DBTT.begin_time ,ASH_CPU, DBT_CPU , ASH_AAS, DBT_AAS from
(
select to_char(begin_time,'MON DD YYYY HH24:MI') begin_time,
round(value/100,2) DBT_AAS
from v$sysmetric_history
where metric_name='Database Time Per Sec'
and INTSIZE_CSEC > 2000
order by 1
) DBTT,
(
select to_char(begin_time,'MON DD YYYY HH24:MI') begin_time,
round(value/100,2) DBT_CPU
from v$sysmetric_history
where metric_name='CPU Usage Per Sec'
) DBTC,
(
select
to_char(to_date(
trunc((id*&v_secs)/ (24*60*60)) || ' ' || -- Julian days
mod((id*&v_secs), 24*60*60) -- seconds in the day
, 'J SSSSS' ), 'MON DD YYYY HH24:MI') start_time,
round(CPU/&v_secs,2) ASH_CPU,
round(total/&v_secs,2) ASH_AAS
from (
select
trunc((to_char(sample_time,'J')*(24*60*60)+to_char(sample_time,'SSSSS'))/&v_secs) id,
sum(decode(session_state,'ON CPU',1,0)) CPU,
sum(decode(session_state,'ON CPU',0,1)) Wait,
-- decode(session_state,'ON CPU','ON CPU','WAIT') event,
count(*) total
from
v$active_session_history ash
where SAMPLE_TIME > sysdate - 60/(24*60)
group by
trunc((to_char(sample_time,'J')*(24*60*60)+to_char(sample_time,'SSSSS'))/&v_secs)
)
) AAS
where
DBTT.begin_time=DBTC.begin_time
and DBTT.begin_time=AAS.start_time (+)
order by DBTT.begin_time ;
Low load – data looks pretty comparable:

Higher load – we start to see consistent differences :

The screen shot below reproduces much of the above except DB Time and CPU used by this Session come from v$systat and not SYSMETRICs and in this case DB TIME is showing a higher AAS than ASH whereas it is the other way around for DB TIME from SYSMETRICs.
John Beresniewicz pointed out that DB Time doesn’t include BACKGROUND processes, so here is slight update just filtering for FOREGROUND processes
Def v_secs=60 -- bucket size
select DBTT.begin_time ,ASH_CPU, DBT_CPU , ASH_AAS, DBT_AAS from
(
select to_char(begin_time,'MON DD YYYY HH24:MI') begin_time,
round(value/100,2) DBT_AAS
from v$sysmetric_history
where metric_name='Database Time Per Sec'
and INTSIZE_CSEC > 2000
order by 1
) DBTT,
(
select to_char(begin_time,'MON DD YYYY HH24:MI') begin_time,
round(value/100,2) DBT_CPU
from v$sysmetric_history
where metric_name='CPU Usage Per Sec'
) DBTC,
(
select
to_char(to_date(
trunc((id*&v_secs)/ (24*60*60)) || ' ' || -- Julian days
mod((id*&v_secs), 24*60*60) -- seconds in the day
, 'J SSSSS' ), 'MON DD YYYY HH24:MI') start_time,
round(CPU/&v_secs,2) ASH_CPU,
round(total/&v_secs,2) ASH_AAS
from (
select
trunc((to_char(sample_time,'J')*(24*60*60)+to_char(sample_time,'SSSSS'))/&v_secs) id,
sum(decode(session_state,'ON CPU',1,0)) CPU,
sum(decode(session_state,'ON CPU',0,1)) Wait,
-- decode(session_state,'ON CPU','ON CPU','WAIT') event,
count(*) total
from
v$active_session_history ash
where SAMPLE_TIME > sysdate - 60/(24*60)
and session_type = 'FOREGROUND'
group by
trunc((to_char(sample_time,'J')*(24*60*60)+to_char(sample_time,'SSSSS'))/&v_secs)
)
) AAS
where
DBTT.begin_time=DBTC.begin_time
and DBTT.begin_time=AAS.start_time (+)
order by DBTT.begin_time ;
and the output is much closer to being inline

-> Note there is often a 1:Many correlation between a single logical object
in the Library Cache, and the physical number of memory objects associated
with it. Therefore comparing the number of Lib Cache objects (e.g. in
v$librarycache), with the number of Lib Cache Memory Objects is invalid.
