  • Table above in RDF
  • ITM Example - using fenced code blocks, see advanced syntax
  • ITM Example - original from 2012-09-25

  • Example 1: A Performance Monitoring Record with One Copy of Each Metric

    Summary contents of the example PMR:

    1. Time collected.
    2. Link to resource that the metrics conceptually describe.
    3. Set of metrics.
    4. Several extension properties (merely to emphasize that extensions are allowed).

    This example shows the same information about the metrics in several different ways.

    1. As a simple table of metric/value pairs.
    2. As a table mapped to the PMR syntax that makes explicit additional information about the metrics, for example the units, that are otherwise only implied by the description.
    3. As an RDF model serialized in Turtle syntax of the entire PMR including all its metrics.
    4. As an RDF model serialized in RDF/XML syntax of the entire PMR including all its metrics.

    Table of Metric/Value Pairs

    Value Description
    32 Percentage Free Memory After Garbage Collection
    1339.2 Request Rate Per Second
    10 CPU Utilization
    45911 Request Failure Count
    2.4 Average Login Request Failures Per Minute
    1024 CPU Speed
    50 Percentage Disk Space Used
    150 Percentage by which space allocated over-commits a Disk
    2 Percentage of Time Thread Pool Maxed
    45 % Buffer Pool Used
    5 Percentage of Time JCA Thread Pool Maxed
    4.5 Response Time
    21 Percentage of Time DB Thread Pool Maxed
    50 Virtual Memory Utilization
    72787723 Garbage Collection Count
    56 VM CPU Percent Ready
    52 Heap Usage
    310 Number of failed SQL Statements
    25.3 Request Failure Rate Per Minute
    3 Average JMS Get Time
    50 Real Memory Utilization
