Monitoring Performance
Monitoring Performance
Monitoring system performance allows you to detect resource consumption problems
that could escalate into unplanned outages. Tandem provides several products to help
you monitor system performance and detect potential resource consumption problems in
your environment:
Tools for Monitoring Performance
Monitor system performance using:
•
Measure
•
Network Statistics Extended (NSX)
•
Tandem Performance Data Collector (TPDC)
•
ViewSys Resource Monitor
Measure
Measure is a data collection and measurement tool that provides a wide range of
performance statistics on system resources. Using Measure, you can gather information
from systems, network components, and your business applications. You can use this
data to balance and tune your system, detect bottlenecks, balance workloads, and
perform sizing evaluations for your new applications. You can also use Measure data for
capacity planning. A sample standard report (shown below) illustrates the data collected
for CPU 1 during a two-hour measurement. The last four lines of the report apply to
measurements taken on TNS/R systems; these lines do not display for measurements
taken on TNS systems.
