Metric Description
LDEV Total IO –
Frontend
The total frontend I/Os rate on this
LDEV over a given 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.
LDEV Total Random
IO – Frontend
The total random frontend I/Os rate
on this LDEV during the entire
collection interval.
LDEV Random Reads
– Frontend
The total random frontend read
I/Os on this LDEV during the entire
collection interval.
LDEV Random Reads
Cache Hits – Frontend
Out of the total random frontend
read I/Os on this LDEV, the number
of random reads available in the
cache.
LDEV Random Writes
– Frontend
The total random frontend write
I/Os on this LDEV during the entire
collection interval.
LDEV Total Sequential
IO – Frontend
The total sequential frontend I/Os
rate on this LDEV over an entire
collection interval.
LDEV Sequential
Reads – Frontend
The total sequential frontend I/Os
rate on this LDEV for a given range
of time.
LDEV Sequential
Reads Cache Hits –
Frontend
The number of sequential frontend
read I/Os serviced from the cache
in terms of the I/Os rate on this
LDEV.
LDEV Sequential
Writes – Frontend
The total sequential frontend write
I/Os for this LDEV over a given
time interval.
Total LDEV IO Miss –
Frontend
The output of LDEV Total IO
[(LDEV Random Read Cache
Hits) + (LDEV Sequential
Read Cache Hits)]
