Item Description
Several new alert Data Table
options have been added.
In order to provide a greater range of alerting options, several
new Data Table options for Alert Rules have been added. These
include:
• statport_nodesum represents the sum of all the ports on
a node. This allows you to generate alerts when nearing
the limits of IOPs/s and bandwidth of a node.
• statport_syssum represents the sum of all the ports on a
InServ system. This allows you to generate alerts when
nearing the limits of IOPs/s and bandwidth of the system.
• statpd_nl7 restricts statpd to only the NL 7.2K RPM PDs.
• statpd_fc10 restricts statpd to only the FC 10K RPM PDs.
• statpd_fc15 restricts statpd to only the FC 15K RPM PDs.
• statpd_ssd150 restricts statpd to only the SSD PDs with
speed 150.
• statpd_sum represents the aggregation of all the PDs in
the InServ system.
• statpd_nl7sum represents the aggregation of all the NL
7.2K RPM PDs in the InServ system.
• statpd_fc10sum represents the aggregation of all the FC
10K RPM PDs in the InServ system.
• statpd_fc15sum represents the aggregation of all the FC
15K RPM PDs in the InServ system.
• statpd_ssd150sum represents the aggregation of all the
SSD PDs of speed 150 in the InServ system.
New alert metric total_utilperc
added
A new alert metric, total_utilperc has been added. While this
metric is available for statport, statvlun, statld and statpd, it is
mainly useful for PDs. For PDs, you can generate alerts when
the PD utilization exceeds some high (say 90%) utilization
meaning that 90% of the time there is some IO operation
outstanding at the PD.
