HP MeasureWare Agent is a comprehensive long-term performance tool
which collects, alarms on, and manages system performance information
as well as metrics from other sources such as database probes. It
provides data and alarms for PerfView, HP OpenView NNM or
IT/Operations as well as third-party products.
Kernel Resource Monitor (KRM)
The Kernel Resource Monitor is included with Event Monitoring
Systems (EMS) Hardware Monitors. The KRM checks HP-UX resources
such as
nproc
(number of processes) which are controlled by the kernel
parameters. KRM continually checks the actual usage of these resources.
If the amount of the usage meets or exceeds a preset value, you are
notified by e-mail, console message, system log, or other means.
This can be useful for tuning the kernel parameters for your particular
system and avoiding panics and performance problems caused when
usage of HP-UX resources approaches too high a level.
The EMS Monitors can be integrated with applications responsible for
maintaining system availability, such as MC/ServiceGuard. If configured
to do so, they can provide event notification to system management
applications such as HP OpenView IT/Operations and HP Network Node
Manager.
The EMS Hardware Monitors use the same EMS framework as the EMS
High Availability (HA) monitors. The HA EMS monitors are a separate
set of monitors available at additional cost.
Some of the hardware monitors for fibre channel products write event
information to text logs read by a new Predictive scanner, emsscan,
which in turn may send events to the Response Center via On-line
Predictive.
The EMS Hardware Monitors (including the Kernel Resource Monitor)
are distributed on the Support Plus CD media and available to download
from http://software.hp.com.
Select “Enhancement Releases” and then “Support Tools for the HP
9000.”
