Monitoring Performance Using ^pButtons Section mgstat Profile * sar -b sar -d sar -r sar -u vmstat Description Caché-specific data taken over the course of the run using the ^mgstat utility. See the Monitoring Performance Using ^mgstat section of the Caché Monitoring Guide. Information about the ^pButtons profile that created this log. Buffer cache usage and efficiency statistics. Disk (block) device throughput and latency statistics. Free memory report. CPU usage statistics include iowait percentage. CPU, queue and memory usage statistics. * This data is collected once per run. 86 Caché Monitoring Guide
9 Monitoring Performance Using ^mgstat This chapter describes the ^mgstat utility, a tool for collecting basic performance data. The utility works with all versions of Caché since release 5.0. Note: This utility may be updated between releases. Contact the InterSystems Worldwide Response Center (WRC) for information about downloading newmgstat.xml from ftp://ftp.intersys.com/pub/performance/. The calling sequence uses the following arguments: Argument sample time Description Required. This argument specifies the frequency (in seconds) for sampling counters; defaults to 2 seconds if sample time is not specified. Note: If you specify a sample time greater than 10 seconds, ^mgstat reduces it to 10 seconds. See the number of samples argument in this table. number of samples Required. This argument specifies the maximum number of samples to be obtained; defaults to 10 iterations if number of samples is not specified. Note: If ^mgstat reduces the sample time, it increases the specified number of samples to ensure that the duration (sample time * number of samples) of the run is effectively the same as it would have been if none of the arguments were modified. filename page length Optional. This argument is used only by other WRC performance tools. Optional. If you run ^mgstat interactively, this argument specifies the number of lines to display before the header rows are repeated. Note: This argument is ignored when you run ^mgstat as a background job. If you specify a page length less than 5 lines, ^mgstat increases it to 5 lines; if you omit this argument or specify a page length of 0, ^mgstat displays the header once, at the beginning of the page. For example, running ^mgstat as a background job to specify that file samples be obtained every 5 seconds until 17280 samplings are obtained (in the Caché Terminal, from the %SYS namespace), enter the following: %SYS> JOB ^mgstat(5,17280) Caché Monitoring Guide 87
