  10. Key ObservationsIT Area1 – Q4 2008 • Application 1 • Exceeding Recommended Thresholds: • 3 servers are approaching recommended capacity thresholds. • Recommendation: • An in-depth analysis of memory usage and growth projection might be performed to ensure the efficient use of existing memory and determine if additional memory procurement is necessary to maintain Capacity thresholds. • Under-utilizing Recommended Thresholds: • All areas are underutilizing CPU. • Recommendation: • Review application growth projections and determine if these systems would be more appropriately combined to ensure effective use of Computer Resources • High Availability : • The combined environment for app1 and app2 will exceed 100% memory utilization if a system failure occurs. This exceeds our standards for maintaining a Highly Available environment. • Recommendation: • An in-depth analysis of memory usage and growth projection might be performed to ensure the efficient use of existing memory and determine if additional memory procurement is necessary to maintain Capacity thresholds. • Application 2 • Exceeding Recommended Thresholds: • All areas are meeting Capacity Utilization Thresholds. • Recommendation: • na. • Under-utilizing Recommended Thresholds: • na. • Recommendation: • na • High Availability : • na • Recommendation: • na.

  18. Appendix A- Definitions Physical Disk Rate = GBL_DISK_PHYS_IO_RATE The number of physical IOs per second during the interval. Only local disks are counted in this measurement. NFS devices are excluded. On Unix systems, this includes all types of physical reads and writes to and from disk, including file system IO, virtual memory IO and raw IO. Peak Disk Utilization = GBL_DISK_UTIL_PEAK This utilization is the percentage of time during the interval that the busiest disk was performing IO transfers. It is not an average utilization over all the disk devices. Only local disks are counted in this measurement. NFS devices are excluded. Logical Disk Utilization = GBL_DISK_LOGL_READ_RATE HP-UX NCR Sinix WinNT The average number of logical reads per second made during the interval. WinNT This includes both buffered (cached) read requests and unbuffered reads. Only local disks are counted in this measurement. NFS devices are excluded. HP-UX NCR Sinix Logical disk IOs are measured by counting the read system calls that are directed to disk devices. Also counted are read system calls made indirectly through other system calls, including readv, recvfrom, recv, recvmsg, ipcrecvcn, recfrom, send, sento, sendmsg, and ipcsend. CPU Utilization = GBL_CPU_TOTAL_UTIL PLATFORMS: HP-UX SunOS AIX NCR Sinix DEC WinNT Win3X/95 Percentage of time the CPU was not idle during the interval. Memory Utilization = GBL_MEM_UTIL PLATFORMS: HP-UX SunOS AIX NCR Sinix DEC WinNT The percentage of physical memory in use during the interval. This includes system memory (occupied by the kernel), buffer cache and user memory. Page 18

  20. Next Steps: • Find and choose software to incorporate a database with monthly reporting. • VM, Unix, Linux, Windows, Blade, SAN, Network • What do you use? • What metrics are important to you? • Build annual Capacity Plan • Do you create one? What do you include? • ITIL Compliance • Do you care about ITIL compliance? • How do you Measure Capacity Management Successes?????? • If you’re interested in sharing how-to’s with me, please email me at mbarton@centene.com Page 20
