Technology Focus: These Are Not Your Granddaddy's System Management Tools

Choosing a performance-management or capacity-planning tool largely depends on whether you think your bottlenecks are primarily caused by hardware, applications, or databases.

 

Let's face it; we're spoiled. If you look at computing strictly from the user point of view, we're all ready to call "slow" any application or system that can't keep up with human decision-making speed. If the computer isn't ready to take the next input on which we've already decided or doesn't provide the information we need the nanosecond we're ready to read it, we notice and we're unhappy.

 

If you're an IT administrator, such expectations can rapidly turn into headaches when users complain, particularly if the users are calling from executive offices. When "fast" isn't good enough, after reaching for the ibuprofen, many administrators next reach for performance-management and capacity-planning software.

Types of Performance Solutions

For the System i, the two dozen or so products that are available to help with performance woes don't follow a particular pattern. In fact, they fall into five general groups.

 

Most common are performance-monitoring (PM) solutions that report and analyze multiple system metrics (e.g., response times, system overheads, CPU use, disk use, output queues) and perhaps even make some specific change recommendations, but they leave to humans the task of actually taking any remedial actions. The members of the second group are utilities that do automatically take some kind of performance-tuning (PT) action, but generally they're limited to a few specific functions. Third are solutions that presume performance problems are caused by how your applications are working, so they focus on applications monitoring (AM) (e.g., resource use, code execution efficiency). Group four zeroes in on database monitoring (DM) as the key problem, primarily examining database transaction speeds, SQL use, and similar issues. The final group employs capacity planning (CP) functions, use of which presumes that your system is ultimately not big enough and may require expansion or replacement. Products with this capability provide means (e.g., "what-if" scenarios, predictive tools, historical views of system resource use) to track system needs and project those needs into the future, given specific growth figures in numbers of users or transactions processed.

 

Products for the System i that run under i5/OS are listed below. We've included a "function types" parameter that categorizes the functions of each vendor's listed product(s) according to the groups specified above.

 

If you're trying to diagnose System i performance problems, you'll find that the solutions available specialize on one of the groups in particular, or at best, straddle two of them. In effect, that puts you in a position where, in order to best cope with your enterprise's particular performance problems, you pretty much need to know already whether the problem is with hardware, applications, or databases. Maybe that issue's a no-brainer for you, particularly if your enterprise has a history of trouble in one of those specific areas. But it's a bit limiting for shops whose systems have functioned fairly well in the past but are only lately showing signs of strain. For those enterprises, products categorized as members of the PM group are definitely the best place to start in looking for diagnostic help.

 

Please bear in mind that the descriptions offered for each product are simply summaries of the most pertinent features and are in no way a complete description of each product's capabilities. You should consult the links provided and other documentation available from the respective vendors to get a true picture of each product's feature set.
