Table 40 Metrics and descriptions (continued)
Description Metric Metric category
The total frontend I/Os rate
on this LDEV over a given LDEV Total IO Frontend
time period. Total I/O of all
the LDEVs created in a
specified Raid Group over
the entire data collection
interval. I/Os on LDEV is
obtained from RMLIB but not
the I/Os on LDEV specific to
the Host Group.
The total random frontend
I/Os rate on this LDEV LDEV Total Random IO
Frontend
during the entire collection
interval.
The total random frontend
read I/Os on this LDEV LDEV Random Reads
Frontend
during the entire collection
interval.
Out of the total random
frontend read I/Os on this LDEV Random Reads Cache
Hits
Frontend
LDEV, the number of random
reads available in the
cache.
The total random frontend
write I/Os on this LDEV LDEV Random Writes
Frontend
during the entire collection
interval.
The total sequential frontend
I/Os rate on this LDEV over
an entire collection interval. LDEV Total Sequential IO
Frontend
The total sequential frontend
I/Os rate on this LDEV for a
given range of time. LDEV Sequential Reads
Frontend
The number of sequential
frontend read I/Os serviced LDEV Sequential Reads
Cache Hits
Frontend
from the cache in terms of
the I/Os rate on this LDEV.
The total sequential frontend
write I/Os for this LDEV over
a given time interval. LDEV Sequential Writes
Frontend
The output of LDEV Total
IO [(LDEV Random Total LDEV IO Miss
Frontend
Read Cache Hits) +
(LDEV Sequential
Read Cache Hits)]
The total random and
sequential frontend read Total IO Reads Frontend
I/Os on this LDEV during the
entire collection interval.
The total random and
sequential frontend write Total IO Writes Frontend
I/Os on this LDEV during the
entire collection interval.
