I/O Performance Tuning of Compaq Servers 21 Novell NetWare For the newer NetWare 5, as well as NetWare 4, MONITOR.NLM provides real-time measurements of OS performance parameters. While MONITOR.NLM, the NetWare Console Monitor, does not provide for logging data to an external file, the on-screen, real-time feedback provides clear insight to the efficiency and effectiveness of the operating system. NetWare Console Monitor is primarily an operating system monitor. By observing trends in parameters such as cache utilization and network traffic, you can pinpoint hardware and software bottlenecks. Monitor is a menu driven utility that provides detailed information for systems such as Storage Devices, Disk Cache Utilization, and LAN/WAN Drivers. To monitor a particular system or component, highlight the appropriate menu item and press Tab to view all available real-time data for that system. Monitor does not affect server performance while monitoring the system, so analysis can be done while the server is under normal operation, even with active connections to clients. Certain parameters that are displayed within MONITOR measure directly the performance of a given system, others, however, may require calculation and cross-referencing to other parameters to fully understand the implications. Similarly, some measurements reflect OS and software parameters, some reflect purely hardware performance or utilization, while others reflect the interdependence of the many systems. Additionally, Compaq Insight Manager can provide insight into CPU and, in some servers, PCI bus or EISA bus utilization. Compaq Insight Manager for NetWare adds the ability to add utilization thresholds to the comprehensive alerting and reporting management system. SCO UnixWare and OpenServer With SCO UNIX operating systems Compaq and SCO have partnered to bring an impressive array of monitoring utilities. Compaq has provided several utilities to monitor the Compaq SCSI Host Bus Adapters (HBA). SCSI Utilities ida_disks - indicates which HBAs in the system are SMART Array Controllers. To use this utility, run it as root with no arguments. It is used by the ida_menu utility to build a list of SMART HBAs to pass to the idadiag utility. ida_menu - allows you to probe SMART Array Controllers for information including: controller type, slot in the system, and board revision number. idadiag - the back-end of the ida_menu utility. It is run with the name of all the SMART Array HBAs as defined by ida_disks. Wide-Ultra SCSI Utilities cpqsmu - allows you to probe the HBAs controlled by the CPQSC driver, and any devices connected to them. cpqultra - allows you to take a snapshot of the HBAs controlled by the CPQSCSI driver and devices connected to them. The following Compaq utilities provide similar monitoring and operation as the SCSI applications listed above. ECG044.0399
