These files can now be processed with the topasout command. The topasout command accepts the parameters shown in Example 5-33. Example 5-33 Usage message of the topasout command # topasout Error, topasout: no filename or options specified topasout [-c|-s|-R daily|-R weekly] [-R detailed|-R summary|-R disk \ [ -i MM -b HHMM -e HHMM]] [xmwlm_recording|topas_recording] flags: -c comma separated output format -s spreadsheet import format -R daily | weekly WLE output report -R detailed | summary | disk (local recordings) -R detailed | summary (topas recordings) -i MM split the recording reports into equal size time\ periods.Allowed Values (in minutes) are 5, 10, 15, 30,60 -b HHMM begin time in hours (HH) and minutes (MM).Range is \ between 0000 and 2400] -e HHMM end time in hours (HH) and minutes (MM).Range is \ between 0000 and 2400 and is greater than the begin time Example 5-34 shows an example of how to do the processes. Example 5-34 topasout processing of recorded data - topas_recording # topasout -c -i 5 -m min,max,mean,stdev,set,exp topas_recording /etc/perf/topas_cec.061013 #ls - l /etc/perf daily wlm xmtopas.log2 topas_cec.061013 xmservd.log1 xmwlm.log1 topas_cec.061013_01 xmtopas.log1 xmwlm.log2 # The file produced will always have a name based on the name of the file used as an argument to the topasout command and will be located in the directory /etc/perf. The data recorded to that file will contain cross-partition CPU measurements. For daily performance statistics taken by the xmwlm command, performance data will be recorded to the directory /etc/perf/daily with a file name starting with xmwlm and can be processed by topasout as well. These files contain CPU, memory, disk, and network measurements as well as some kernel statistics. Example 5-35 on page 335 shows how you can use the statistics. 334 <strong>Advanced</strong> <strong>POWER</strong> <strong>Virtualization</strong> on IBM System p5
Example 5-35 topasout processing of recorded data - xmwlm_recording # topasout -c -i 5 -m min,max,mean,stdev,set,exp xwlm_recording /etc/perf/daily/xmwlm.061016 # ls /etc/perf/daily xmwlm.061016 xmwlm.061016_01 xmwlm.061017 # These files can be used as input files for further processing, for example, by the Java utility pGraph, or the Performance Graph Viewer by Federico Vagnini, an unsupported freeware tool available from: http://www-941.haw.ibm.com/collaboration/wiki/display/WikiPtype/Perform ance+Graph+Viewer This tool is able to produce HTML pages in batch mode and show graphs in interactive mode. Nmon recordings can be processed as well by this tool. 5.5.5 New monitoring commands on AIX 5L V5.3 AIX 5L V5.3 introduces some new monitoring commands specific to virtualized environments. These are discussed in this section. The lparstat command The lparstat command shows configuration and performance information for the partition in which it is run. This command works on all AIX 5L V5.3 systems, even those that do not support logical partitioning (though obviously without LPAR information). It supports dedicated and shared partitions, with or without SMT. The lparstat command has four operational modes: Monitoring The default, without any flags Hypervisor summaryWith the -h switch Hypervisor hcalls With the -H switch System configurationWith the -i switch In all modes, except with the -i switch, lparstat prints a one-line summary of the system configuration before displaying the corresponding information. The lparstat command monitoring mode With no switches, the lparstat command monitors the partition’s resource usage. Like many of the stat commands, the lparstat command takes optional Chapter 5.
