Many operating systems provide utilities to administer and troubleshoot. Most of the operating systems provide context sensitive help to use the tools.

You can use the following Windows operating system utilities to monitor Vector:

For a full description of the Windows utilities, see your Windows documentation.

The Windows Diagnostics program can help you determine your operating system’s configuration. This tool can be found in Control Panel, System and Security, Administrative Tools, Computer Management.

Performance Monitor is a Windows graphical tool for measuring the performance of your own computer or other computers on a network. On each computer, you can view the behavior of objects such as processors, memory, cache, threads, and processes. Each of these objects has an associated set of counters that provide information on such things as device usage, queue lengths, and delays, as well as information used for throughput and internal congestion measurements.

It provides charting, alerting, and reporting capabilities that reflect current activity along with ongoing logging. You can also open log files at a later time for browsing and charting as if they were reflecting current activity. To monitor performance on Windows, see the operating system documentation.

Event Viewer is a tool for monitoring events in your system. You can use Event Viewer to view and manage System, Security, and Application event logs. To access the Event Viewer, right-click on the Computer icon and select Manage. The Computer Management Window is displayed. The Event Viewer is available under the System Tools.

This program can be used to view the system configuration and environment. For a description of how the information is presented and the capabilities of the utility, see the online help.

The Task Manager enables you to monitor and control your computer and what is running on it. It shows you programs and processes that are running as well as performance. To access the Task Manager, right click an empty area in the task bar and click Start Task Manager.

You can use the following Linux operating system utilities to monitor Vector:

For a full description of the Linux options, see your Linux documentation (or online help). A detailed description of the utilities can be found in the Command Reference.

This command provides virtual memory and cpu information on each active process submitted from your account. Here is a sample ps output:

The display fields are as follows:

The iostat command returns information about I/O status. It lists statistics on current I/O activity for each disk device and system CPU utilization percentages. Here is a sample iostat output:

The vmstat (Virtual Memory Statistics) command returns virtual memory status information, including process states and paging activity. Here is a sample vmstat output:

The procs columns define the process states: in run queue (r), blocked for resources (b), and runnable or short sleeper (w).

The memory columns show virtual and real memory status: avm is active virtual pages (belonging to processes active in approximately the last 20 seconds), fre is size of the free list, and di is the number of dirty pages.

The page columns show page faults and paging activity. These are expressed in units per second, averaged over 5 seconds: re are page reclaims, rd are page reclaims from the dirty list, and pi, po are pages paged in/out. The de field is anticipated short-term memory shortfall.

The disk columns list disk activity, showing the device name and operations per second.
