Total IO – Frontend
Description
The average frontend I/Os rate on
this port over an entire collection
interval. Port Average IO shown in
PA is average of average IO.
Average Port IO is the value within
a period of sampling time at one
minute interval from RMLIB call
(this could be running average in a
min). PA collects this data every
minute and updates according to
the configured port collection
frequency. For example, consider
port collection is configured for 5
minutes, then every minute
average port data is collected and
stored in-memory. At the end of 5th
minute, average of all collected
average port data is calculated.
The total frontend I/Os on this port
over an entire collection interval.
The frontend Read I/Os on this port
over an entire collection interval.
The frontend Write I/Os on this port
over an entire collection interval.
The total IO of all the LDEVs
created in a specified RAID Group
for the given Host group over the
entire data collection interval.
NOTE:
If the same host group is
exposed to more than one
PORT then the IOs to
hostGroups is seen on all
PORTS where it is exposed.
Calculation of Total IO
depends on the LDEVS and
not on PORTS, while
summing up, the same
hostgroup is exposed to
more than one PORT, we are
considering only once.
Metric Category, metrics, and descriptions
The total IO is obtained
by summing up all the
IO of all the LDEVS for
the given host group.
