This log file describes the server statistics cache.
Location
This file is located in the log_root/visualization directory
by default. You can configure the location of the visualization data
service log files.
Usage notes
- name: Specifies the server name.
- node: Specifies the node name.
- version: Specifies the version of WebSphere® Virtual Enterprise that is running on the
node.
- weight: Specifies the dynamic workload management (dWLM)
weight of the server.
- cpu: Specifies the percentage of the processor that is
being used.
- usedMemory: Specifies the number of kilobytes of memory
that is used in the Java virtual machine (JVM) run time. This statistic
is available only for server instances containing WebSphere Application Server.
- uptime: Specifies the number of milliseconds that JVM has
been running. This statistic is available only for server instances
containing WebSphere Application Server.
- totalRequests: Specifies the number of total requests for
the server. This statistic is available only for server instances
containing WebSphere Application Server.
If your environment contains other servers, including external
WebSphere application servers, you can manually calculate a value
that is similar to the value of the totalRequests metric. Locate all
entries for a particular server in the TCModuleInstanceStatsCache.log file.
Using the beginning and end time stamps, calculate the sum of the
serviced metric for the server. For more information, see TCModuleInstanceStatsCache.
- updateTime: Specifies the time that the statistics were
provided.
- db_averageResponseTime: Specifies the
average response time for the database server.
- db_throughput: Specifies the throughput
for the database server.
- highMemMark: The highest amount of memory
in megabytes consumed over the life span of the server.
- residentMemory: The amount of physical
memory not shared with other processes that the JVM is using in kilobytes.
- totalMemory: Specifies the total amount
of memory that the JVM is using in kilobytes.
- totalMethodCalls: Specifies the total
number of enterprise Java bean (EJB) module method calls.
