Available Graphs Option The Available Graphs option appears on the Draw Graphs dialog box.Figure 10-9. Available Graphs Option The Available Graphs list box lists the nine global, four disc space, and six application graph types. Normally, the default selection is Global Bottlenecks. If the logfile highlighted in the Available Logfiles list box contains only application data, the default is Application Bottlenecks. Similarly, if it contains only disc space data, the default is the Disc Space graph. Global Graphs The nine global graphs are as follows: * Global Bottlenecks. This graph displays system-wide activity for the three primary system resources: CPU, disc, and memory. * Global Transaction Response. This graph displays system-wide terminal transaction rates and terminal response time measurements. * Global CPU Utilization. This graph is displays data for five major consumers of CPU resources: Session, Job, System, Other, and Paused. * Global System CPU Utilization. This graph displays the percentage of CPU used by five specific system overhead activities: Mem Mgr, Dispatch or Cache, JCS, Processes, and Other. MPE VE systems show Cache. MPE XL systems show Dispatch instead of Cache. * Global Disc Summary. This graph displays logical, physical, and memory manager disc read-write activity and a peak disc utilization percent for the busiest disc on the system. * Global Disc Detail. This graph displays the utilization percentage and read-write rates for individual discs. Two Disc Detail graphs can be displayed in the same graph window. The first graph shows the five busiest discs in the display period according to percent of time utilized. The second graph shows utilization and read-write rates for individual discs. * Global Physical Disc by Task. This graph displays global disc read-write activity attributable to sessions, jobs, system processes, and the memory manager. * Global Queue Depth. This graph displays the average number of processes waiting on resources: CPU, Disc, Memory, Impede * Global Jobs & Sessions. This graph shows the number of jobs and sessions logged on and active. Disc Space Graphs The four disc space graphs are as follows: * Disc Space. This graph shows the total available disc space over time and how it was used. Uses of disc space are permanent files, transient (or virtual) memory swapping area, and free space. Free space may be free for transient only, free for permanent files only, or free for transient or permanent depending on the features of the operating system used. * Disc Free Space. This stacked graph displays overall disc free space fragmentation over time by showing the total disc space available in contiguous pieces of varying sizes. The size ranges are in sectors. * Disc Space Users. This graph shows the amount of permanent disc file space for the five accounts (or user-defined disc groups) that had the highest average usage during the time period displayed. If more than five disc groups or accounts are present, only the five with the highest average disc space usage during the graph interval are displayed in the first-level graph. Scroll vertically to second-level Disc Space Users graphs, which show the amount of permanent disc file space for an individual account (or user-defined disc group). * Disc Space--Virtual (MPE V) or Disc Space--Transient (MPE XL). This graph shows the peak virtual (MPE V) or transient (MPE XL) disc space used each day, the amount of disc space reserved for transient or virtual space, and the amount of free disc space for permanent files. On MPE XL, space for permanent files may also be used for transient space if necessary. Note that the Reserved and Available values on this graph are sampled once a day and do not represent peak or average values over the day.
Tip A quick way to check whether a highlighted logfile that contains disc space data is from an MPE V or MPE XL system is to look for this graph in the list of available graphs. If you see the Virtual graph, the logfile contains MPE VE data; if you see the Transient graph, it contains MPE XL data.
Application Graphs The six application graphs are as follows: * Application Bottlenecks. This graph displays utilization data by application for two system resources: CPU and disc. * Application Transaction Response. This graph displays terminal transaction rates and terminal response time measurements by application. * Application CPU Utilization. This graph displays the percent of elapsed time that the CPU is busy executing instructions on behalf of the application. * Application Transaction Response. This graph displays interactive session activity and response time by application. * Application Response States. This graph displays application response states; that is, where an application spends time when it is not waiting on the user or another long-term event (tape mount, pause intrinsic). * Application Queue Depth. This graph displays load average or queue depth in terms of CPU, Disc, Memory, and Impede for each application defined to HP LaserRX/MPE. * Application Resource Usage. This graph displays the rate at which resources are used for each application defined to HP LaserRX/MPE. For each set of application measurements, you can display two graphs using the same graph window. To do so, you can use the vertical scroll bar at the right side of the graph: * When the scroll box is at the top of the scroll bar, Graph 1 (a ranked application summary) is displayed. Summary graphs list the five busiest applications in the display period. The criteria for busiest varies according to the type of graph. The application labels on the top of the graph are in ranked order. The busiest application for the period is on the left. * When the scroll box is not at the top of the scroll bar, Graph 2 (an application-by-application detail) is displayed. Individual application graphs display variables for one application at a time. Related Topics See Appendix A for more specific information about graph variables and tabular data.
