This guide contains the following new or changed information for the Performance Co-Pilot release 2.1:
The cron scripts for performing PCP housekeeping task have been renamed:
A set of parameterized pmie rules have been developed which are applicable to most systems. A new utility, pmieconf, allows these rules to be enabled or disabled, or the parameters and thresholds adjusted for a specific system (see “Creating pmie Rules with pmieconf” in Chapter 6).
Extra support for running pmie as a daemon has been added (see “Management of pmie Processes” in Chapter 6).
A new tool to convert arbitrary time-stamped data streams to PCP archive logs, called pmimport, has been added. pmimport currently supports the conversion of sar/sadc data files from the IRIX operating systems 6.2, 6.3, 6.4 and 6.5, and UNICOS 9.0.
The new sendmail PMDA exports mail traffic statistics as collected by sendmail.
To enable additional quality of service and availability monitoring with the shping PMDA, new utilities have been added to check the status of HIPPI interfaces on a system (hipprobe) and to interrogate the Auto-FS daemon (autofsd_probe).
A new visualization utility, xlv_vis, has been added which displays a three-dimension bar chart of XLV volume activity.
As an aid to creating pmlogger configuration files, pmlogconf is a new tool that allows selection of groups of commonly desired metrics and customization of pmloggger configurations from a simple interactive dialog.
New capabilities have been added to assist in the estimation of PCP archive sizes. This is achieved using the -r option for pmlogger and the -s option for pmdumplog.
Some metrics have been added to the hotproc PMDA. The metric hotproc.control.config exports the parsed one line representation of the configuration predicate and the metrics, hotproc.predicate.*, export the values of the variables used in the predicate.
pmchart has been updated as follows:
Dynamic views are now supported where the view specification is computed by an application (most often /bin/sh) at the time the view is instantiated.
The menus have been slightly rearranged.
A new -C option allows pmchart to parse a configuration checking for errors and to exit.
pmie has been enhanced as follows:
Actions may now have an arbitrary number of quoted arguments.
Metrics with dynamic instance domains are now supported.
The language has been extended to allow two new operators: match_inst and nomatch_inst
Macro expansion can now occur anywhere in the pmie rule specifications.
mlogsummary has been extended with a -B option to display the distribution of values across a PCP archive in a given number of bins, with a -p option to adjust floating point precision and the -I option now reports when the minimum and maximum occurred.
The pcp startup script, /etc/init.d/pcp, now starts pmlogger up in the background.
Figures and examples have been updated to reflect the new PCP names and paths.
In addition, miscellaneous editing changes were made throughout the document.
