+

+This chapter of the Performance Co-Pilot tutorial discusses the steps +required to integrate PCP into the various management frameworks available. +It takes into consideration the distributed nature of both the management +frameworks and of the PCP tools, and how best to combine the functionality +they offer.

+

+For an explanation of Performance Co-Pilot terms and acronyms, consult +the PCP glossary.

+ +


+ + +

Points of Integration

+

+Following is a brief description on how PCP can be integrated in terms of +some of the aligned features of PCP and the typical management framework. +

Data

+

+The PCP archive logging utility pmlogger(1) +generates performance data files in the PCP archive format, +which is specifically designed for optimal fetch latency +when retrieving data from the archive for replay and when seeking to +random time points in the archive.   +This format is specific to the PCP tools and the PMAPI, and clearly +external interfaces are necessary for non-PCP tools to read the data. +

+The LOGIMPORT(3) APIs provide a mechanism for +importing data into a PCP archive. Using these services, tools +are provided to import common sources of performance data such as +spreadsheets, binary data from sar(1) and iostat(1) output. +Other tools can easily be developed in C or Perl, see LOGIMPORT(3), +pmiStart(3) and PCP::LogImport(3). +

+There are a number of PCP tools which have specifically been developed with +the aim of producing a format which is easily incorporated into an external +framework, database, or spreadsheet application - for example, the +pmdumptext(1) and pmlogsummary(1) tools both provide options to +output data in a time-stamped, tab-delimited or comma-separated form, which +is easily incorporated into other tools.  +PCP also provides daily log rotation, merging and culling facilities for +multiple collector hosts from a single monitor host, as well as the +automated pmchart/cron/pmsnap performance graph image generation +facility. +

+

+Due to the unlimited potential consumers of this historical performance data, +it is left as an exercise for the reader to figure out how best to incorporate +this data into their own environment. +

+

+Note that all of the PCP tools are "timezone-aware" and can switch +between the timezone of the monitoring machine and the timezone of the +collector machine for which the archive was generated (this information is +stored in the archive).  Also, PCP archives can be generated on a machine +of one operating system version, architecture or byte-order, and replayed +on a completely different machine. +

+

Events

+

+Among the more compelling reasons for making use of a management framework +to administer an enterprise are the distributed monitoring and centralized +analysis aspects.  +All frameworks provide event monitoring facilities, of varying complexity.  +Some provide simple point to point event generation, others have proxy event +servers which allow events to be filtered and then potentially passed upstream +to another event monitor.  +To allow the framework to be extended, the frameworks will typically provide +a mechanism for external applications to push their own events into the +framework, and it is this feature which we wish to exploit in our PCP +integration efforts.  +

+

+Although PCP does provide a powerful inference engine in pmie(1) (as well +as a far richer set of performance metrics than the more generic frameworks can +provide, and low latency protocols designed specifically for transporting +performance data quickly), no attempt is made to provide an event +"sink" - some application which will display and filter +performance events for the user.  +From an enterprise management point of view, an event monitoring +facility specifically for performance events would be exactly the wrong +thing to do from within PCP - system administrators managing a wide array of +different machines should expect to see all system-wide events coming to a +single point for their notification. +

+

+So, the integration point must be from pmie(1) - when it detects an +abnormal performance situation, it must pass it on in the most appropriate +manner possible. Unfortunately, the various event management frameworks +have widely differing mechanisms for receiving events, so each framework +must be handled separately in order to make best use of their event viewing +and filtering capabilities. +

+
+ +
+

+The diagram shows a typical pmie(1) setup - rattle.melbourne.sgi.com +running pmie, fetching performance data from a variety of sources, then +evaluating its set of performance rules and generating events into whichever +event "sinks" have been specified.  +Specifying how to generate an event, which rules to use, how frequently to +evaluate each of the rules, which hosts to monitor, etc, is performed by +the pmieconf(1) utility, which can be extended to allow new frameworks +to be incorporated. +

+

User Interface

+

+A number of the enterprise management frameworks have the ability to provide +closer integration between the tools themselves, for example starting PCP +tools from a menu option of some of the framework's tools, or by installing +additional on-line help for the performance events which PCP generates.  +This level of integration is not attempted, and is not seen as providing +much value in practice.  +The pmieconf(1) utility is the definitive +source of help text for the performance events generated by pmie(1) - +it describes the rules and each of the customizable variables affecting +the rules (including the "global" variables affecting all of the +rules, such as where to send events when a performance event is generated). +

HP OpenView (Hewlett-Packard)

+

+Step-by-step on how to setup and ensure pmie(1) can talk to OpenView: +

+ +

+

+ +
+The xnmevents(1) GUI connects to the pmcd(1) daemon on the monitoring +node which supplies any new events which arrive while xnmevents is +running. +

+The image to the right shows the xnmevents main window. +On receipt of a new pmie event, the "Threshold Events" +toggle button changes +color according to the event severity, indicating that there are new events +- clicking on the toggle button brings up the viewer window (shown below). +

+

+The viewer lets you view, filter, and +acknowledge events (once all events are acknowledged, the "Threshold +Events" button becomes white - until the next event arrives). +

EnlightenDSM (Enlighten Software Solutions)

+Step-by-step on how to setup and ensure pmie(1) can talk to +EnlightenDSM: +

+ + +Configuration options - using pmieconf(1) to customize the setup: +

+The only configurable option of note for Enlighten DSM is the ability +to change the severity setting for individual events, event groups, or +globally for all events (where severity is a number between a low of 1 and +a high of 5, and the default severity value for pmie(1) events is 2): +

+wobbly# pmieconf modify filesys.filling enln_severity 4
+wobbly# pmieconf modify cisco enln_severity 5
+wobbly# /etc/init.d/pmie start
+
+

Extending to Other Frameworks

+

+All of the enterprise management frameworks we've come across provide some +mechanism for generating events from outside the framework.  +This is usually in the form of a stand-alone utility, but could also be an +API, which packages the attributes associated with an event (these attributes +are usually things like severity, source host, message text, etc) and sends +this to the monitoring host. +

+

+Since pmie(1) supports running an arbitrary command upon detection of +a performance event (in addition to its other native actions, such as writing +an entry in the system log file), this is the hook we'll use to add support for +additional frameworks. +

+

+Steps involved when integrating other frameworks with PCP: +

+ +

If the framework is sufficiently common that other people may wish +to use your new pmieconf(1) "action", feel free to +share it and we'll incorporate it into +future PCP release.
