When you expand a managed server object, you can view details about the contents of the server. The following sections detail the available objects on a managed server and provide information about the statistical information available in the views for each object. This topic contains the following sections:
The following table shows the hierarchy of available objects on a managed server along with their associated icons. For more information about the available views associated with an object, follow the corresponding link.
Viewing processor speed helps you analyze and balance loads across servers. Viewing processor utilization data helps you detect problems with utilization and determine when server load is light enough to schedule tasks such as server backups. The server operating system (OS) automatically determines the CPU speed and is reported based on the OS data.
Processor speed is a major determinant of server performance. Therefore, it is important to know the processor speed of your servers when analyzing server load and balancing load across multiple servers. For example, one server might be handling twice as many users as another, but if the processor is twice as fast, the load might still be distributed correctly.
You should maintain a baseline of processor utilization for a server so that you can recognize when a server's processor utilization is higher than normal.
You can display the following views of information about the processors on your managed servers:
You can access the Summary View for the Processors object container after expanding the following server objects: Devices > Processors. This view displays the following information for each processor object in the container:

Storage Devices
You can get detailed information about the disk drives in a managed server, including disk size in megabytes, disk types, block size, and so on.
You can also view partition information for each disk drive. Partition information is especially informative because you can determine whether a partition is fault tolerant and whether the hard disk is losing data integrity.
Fault tolerance of a NetWare partition is part of the detailed information provided by ZfS server management. To determine whether a hard disk is losing data integrity, examine the redirected area. A number in the redirected area indicates the number of data blocks that have been redirected to the Hot Fix Redirection Area to maintain data integrity. The higher the redirected area number, the more faulty blocks there are on the hard disk. A redirected area growing over a period of time indicates a hard disk going bad.
On a NetWare server managed by the Management Agent for NetWare or a Windows NT server managed by the ZfS management agent, the Agent automatically gathers trend data on CPU usage, memory usage, and network interface traffic. In ZfS, you can view current trend data, or historical trend data by hour, day, month, or year. Monitoring trend data helps you with tasks such as setting alarm thresholds, determining who is using the server and when the server is used heavily, troubleshooting problems, balancing loads across multiple servers, and planning resources.
You can display the following views of information about the storage devices on your managed servers:

Adapters
You can get detailed information about the network and disk adapters in a managed server, including I/O port, memory address, and interrupt configuration.
You can use this data to detect configuration problems such as the same address or interrupt is configured for two boards inside the server, or for a board and a component of the server's hardware. No two boards can use the same I/O port, memory address, and interrupt.
Problems with LAN adapters cause network problems, such as servers and workstations not being able to communicate. You can use the data collected on the LAN adapter to determine whether the frame type used by a network board is bound to a supported protocol. (A single network board might be bound to several protocols.) You can immediately tell whether a problem is due to something as simple as using the wrong frame type on the workstation (for example, an Ethernet_II frame type on the server and the Ethernet_802.2 frame type on the workstation).

Disk Cache View
This view displays utilization for disk cache memory. Use cache utilization statistics to determine when you need to install more RAM for cache. You can select this view after expanding the following server objects: Operating System > Kernel > Memory. It provides the following information:
Short Term Cache Hits %: Percentage of requests in the last second for disk blocks that were already in cache memory. When the requested data is already in memory, disk reads don't need to be made. If this value falls below 98%, consider installing more RAM for cache. Also compare with Long Term Cache Hits.
Short Term Cache Dirty Hits %: Percentage of requests in the last second for disk blocks that were already in cache memory but were dirty. Dirty cache must be written to disk before being used. Also check Long Term Dirty Cache Hits and LRU Sitting Time.
Long Term Cache Hits %: Cumulative percentage of requests for disk blocks that were already in cache. When the requested data is already in memory, disk reads don't need to be made. Use this cumulative percentage to assess overall disk cache utilization. If this value falls below 90%, install more RAM for cache.
Long Term Cache Dirty Hits %: Cumulative percentage of requests for disk blocks that were already in cache memory but were dirty. (Before dirty cache can be used, it must be written to disk.) Use this cumulative percentage to assess overall disk cache utilization. If this value is high or steadily incrementing, add more RAM for cache. Also check LRU Sitting Time.
Total Cache Blocks Allocated: Cumulative number of requests for disk cache blocks that have been made since the server was started or rebooted. This value is the sum of the values of Allocated from Available List and Allocated from Least Recently Used (LRU). If the value of Allocated from Available is much higher, the server has sufficient RAM for cache. If the value of Allocated from LRU is high, install more RAM for cache.
Cache Blocks Allocated from Available List: Number of requests for disk cache blocks that were filled by blocks in the available list (blocks that were not being used). When there are no free blocks available, requests are filled from the LRU list of cache blocks. If this value is much higher than the Allocated from LRU value, the server has sufficient RAM for cache.
Cache Blocks Allocated from LRU: Number of requests for disk cache blocks that were filled by blocks from the Least Recently Used cache blocks. The system writes pending requests from the LRU cache block to disk then frees the block for the current request. Because LRU caches used only when no other cache is available, a steadily incrementing count indicates more RAM is needed.
Number of Times in Last 10 Minutes that the OS Had to Wait: Number of times in the last 10 minutes that the OS waited for an LRU block in order to fulfill a request. If this value is greater than 7, install more RAM for cache.
Number of Times OS Had to Wait: Number of times that the OS waited for an LRU block in order to fulfill a request.
Total Number of Times the Write Request Was Delayed: Number of times a write request was delayed because there were too many writes to perform or because the disk channel was busy. A high value indicates either that the disk channel has too much I/O traffic or that you need to install more RAM for cache.
Number of Times the Request Was Re-tried: Number of times a disk cache request had to be retried because the target block was being used. If this value is high or steadily incrementing, install more RAM for cache.
Virtual Memory View
This view displays information about the virtual memory system. Use these statistics to monitor the efficiency of server memory usage. If these values are fairly stable over time and if server performance is satisfactory, the server has adequate memory for its load. For example, if the value of Page faults increases, this indicates that the server performance is degrading. Conversely, if the Free swap pages value increases, it is an indication of better server performance.
You can select this view after expanding the following server objects: Operating System > Kernel > Memory. It provides the following information:
Total Page-In Requests: Number of requests that were made to move virtual memory from swap files since the server was started (server up time).
Page-In Requests in Last 5 Seconds: Number of requests to move 4 KB virtual memory pages from swap files.
Total Page-Out Requests: Number of requests that were made to move virtual memory to swap files since the server was started (server up time).
Page-Out Requests in Last 5 Seconds: Number of requests to move 4 KB virtual memory pages to swap files.
Total Swap Pages: Number of 4 KB pages in this server's virtual memory system. (The size of the swap file in memory pages is the total number of bytes divided by 4 KB.) The size of the swap file grows or shrinks dynamically to match the memory requirements of the server's load.
Free Swap Pages: Number of 4 KB pages that are available for use by the virtual memory system.
Reserved Swap Pages: Number of 4 KB pages that are reserved by the virtual memory system.
Total Page Faults: Number of times the virtual memory system retrieved from the swap file since the server was started (server up time).
Page Faults in Last 5 Seconds: Number of times in the last five seconds that the virtual memory system retrieved from the swap file. (This means that accessed memory wasn't backed by physical memory.)
Address Spaces
NetWare runs in the OS address space (kernel) along with LAN drivers, storage device drives, MONITOR, and network management agents (NMAs). OS address space is backed by physical memory.
All other address spaces are user space (ring 3) and are backed by virtual memory. Applications running in user space cannot cause the server to abend if the address space faults.
You can display the following view of information about address spaces on your managed servers:

A server application, such as GroupWise®, Lotus Notes*, or an Oracle* database, can be loaded in its own address space (user space or ring 3).
Mapped Pages: Total number of physical memory pages backing this address space. Note that the OS address space (kernel) is the only address space backed by physical memory.
Restarted: Total number of times this address space faulted and restarted automatically. A value of zero (0) indicates that no fault has occurred. A non-zero value indicates that an address space has faulted and recovered. Follow online Troubleshooting documentation for core dump instructions for address spaces.
