You can use the included monitoring
console,
APIs, MBeans, logs, and utilities to monitor the performance of your
application environment.
Statistics overview
Statistics in WebSphere® eXtreme Scale are
built on an internal statistics tree. The StatsAccessor API,
Performance Monitoring Infrastructure (PMI) modules, and MBean API
are built from the internal tree.
Monitoring with the web console
With the web console,
you can chart current
and historical statistics. This console provides some preconfigured
charts for high-level overviews, and has a custom reports page that
you can use to build charts from the available statistics. You can
use the charting capabilities in the monitoring console of WebSphere eXtreme Scale to view the overall
performance of the data grids in your environment.
Monitoring the health of the environment
The message center provides an
aggregated view of event notifications for log and first-failure data
capture (FFDC) messages. You can view these event notifications with
the message center in the web console, the xscmd utility, or programmatically with MBeans.
Monitoring with CSV files
You can enable monitoring data collected for a container
server to be written to comma-separated values (CSV) files. These
CSV files can contain information about the Java virtual machine (JVM),
map, or ObjectGrid instance.
Enabling statistics WebSphere eXtreme Scale uses
an internal statistics model to track and filter data, which is the
underlying structure that all data views use to gather snapshots of
statistics. You can use several methods to retrieve the information
from the statistics modules.
Monitoring with the xscmd utility The xscmd utility
replaces the xsadmin sample utility as a fully
supported monitoring and administration tool. With the xscmd utility,
you can display textual information about your WebSphere eXtreme Scale topology.
Monitoring with WebSphere Application Server PMI WebSphere eXtreme Scale supports
Performance Monitoring Infrastructure (PMI) when running in a WebSphere Application Server or WebSphere Extended Deployment application server. PMI collects
performance data on runtime applications and provides interfaces that
support external applications to monitor performance data. You can
use the administrative console or the wsadmin tool to access monitoring
data.
Monitoring with vendor tools WebSphere eXtreme Scale can
be monitored using several popular enterprise monitoring solutions.
Plug-in agents are included for IBM® Tivoli® Monitoring
and Hyperic
HQ, which monitor WebSphere eXtreme Scale using
publicly accessible management beans. CA Wily Introscope uses Java™ method instrumentation to capture
statistics.
Monitoring eXtreme Scale information in DB2
When the JPALoader or JPAEntityLoader is used with DB2® as the back-end database, eXtreme Scale-specific information
can be passed to DB2. You can
view this information by a performance monitor tool such as DB2 Performance Expert to monitor
the eXtreme Scale applications
that are accessing the database.
