11.5 Performance reporting

< Day Day Up >

In preparation for understanding capacity requirements, real data is required. To provide examples of how to collect this data, and how to interpret this data, NETSNMP was used with the NotesBench driver, with the reporting provided by Velocity Software's ESALPS. Report examples in this chapter are produced by ESALPS.

Velocity Software staff participated in this redbook project because of their knowledge of z/VM performance, Linux consolidation practices, and Linux skills. ESALPS was used to collect the performance data, as well as for analysis and presentation; see 12.2, "ESALPS overview" on page 298 for more details about this tool.

NETSNMP (from sourceforge.org) was run on three Linux servers that had Domino installed. Data was collected using ESALPS to create a set of history files from which this data was reported. This history data includes VM data and Linux data with a one-minute granularity.
