Program monitor pf usage windows 2003

Note that if an absolute start time is given using the start command, the offset into the script will correspond to that absolute time. The default offset for MGEN is 0. While this is sometimes helpful at high packet transmission rates, it comes at a cost of high CPU utilization by mgen. The text- based log file information will be directed to stdout unless you specify a filename with the output or log command.

Mgen will exit after the file conversion is complete. If no ttl option is used, MGEN will behave according to the operating system's default behavior. As with ttl and interface, tos is a. If no tos option is used, MGEN will behave according to the operating system's default behavior. Causes mgen to include an optional 3.

CRC at the end of its messages. Use this option when it is. This is the recommended option when MGEN checksum operation is desired so that both senders and receivers are providing and validating checksums, respectively. This command causes mgen to exit. This is useful for run- time control of mgen instances. This enables logging of events and error messages in localtime. By default, events are logged in Greenwich Mean Time.

When the number of pending messages for a flow exceeds this limit, the message transmission timer will be temporarily deactivated and any pending messages will transmitted as quickly as possible.

The timer will be reactivated once the pending message count falls below the queue limit, and message transmission will return to the previously scheduled rate of transmission. No pending message count will be accumulated and message transmission will suceed or fail depending on transport availability.

As with tos, ttl and interface, broadcast is a. It does not affect whether MGEN senders send the requested data attribute. Is there any way to determine if it's a specific program and to fix it?

For a good analysis it is recommended that we have atleast samples. Then click on Apply and in the main Performance monitor window you would see the log with the name you provided earlier appear there. Right click on that log and start it and continue to monitor the server. Is your pagefile system managed? If your seeing a lot of thrashing you may want to change it to manual and just plug in a 16gb page file since Windows is designed to setup a pagefile for one and a half the amount of physical memory.

There are some who believe that you can delete the pagefile unless you have specific applications that call for it but I think my first stop would be setting it to manual and plugging in my own designated size. I have also read some articles relating to memory thrashing involving SQL databases.

You may want to look into SQL and check the settings there as well. When you set up a bit version or a bit version of Windows Server or Windows XP, a page file is created that is one and a half times the amount of RAM that is installed in the computer provided there is sufficient free space on the system hard disk.

However, as more RAM is added to a computer, the need for a page file decreases. If you have enough RAM installed in your computer, you may not require a page file at all, unless one is required by a specific application.

The following chart illustrates the amount of RAM and the number of CPUs that can be installed on a computer depending on the operating system that is installed.

There is no specific recommendation for page file size. Your requirements will be based on the hardware and software that you use and the load that you put on the computer. To monitor page file usage and requirements, run System Monitor, and gather a log during typical usage conditions. Focus on the following counters. Note Page file use should be tracked periodically.

When you increase the use or the load on the system, you generally increase the demand for virtual address space and page file space. Office Office Exchange Server. Not an IT pro?

Note that the supercomputer effectively prohibits disk swapping of user processes, and my home PC has a smallish page file.

Memory usage pattern. Say the prime data structure is called supp. Then, for each integer k , to fill supp[k] , the data from supp[k-1] is required. Note that the memory is only allocated through the STL containers, I never explicitly new or malloc myself. On Linux, it appeared the easiest to just catch the heap pointers through sbrk 0 , cast them as bit unsigned integers, and compute the difference after the memory gets allocated, and this approach produced plausible results did not do more rigorous tests yet.

On Linux, I'd try getrusage or something to get the equivalent. Thanks conio. On Windows, the GlobalMemoryStatusEx function gives you useful information both about your process and the whole system. To know how much physical memory your process takes you need to query the process working set or, more likely, the private working set. The working set is more or less the amount of physical pages in RAM your process uses.

Private working set excludes shared memory. You can also use QueryWorkingSet Ex and calculate that on your own, but that's just nasty in my opinion. You can get the non-private working set with GetProcessMemoryInfo.

But the more interesting question is whether or not this helps your program to make useful decisions. If nobody's asking for memory or using it, the mere fact that you're using most of the physical memory is of no interest.

Or are you worried about your program alone using too much memory? You haven't said anything about the algorithms it employs or its memory usage patterns. If it uses lots of memory, but does this mostly sequentially, and comes back to old memory relatively rarely it might not be a problem.

Windows writes "old" pages to disk eagerly, before paging out resident pages is completely necessary to supply demand for physical memory.

If everything goes well, reusing these already written to disk pages for something else is really cheap. If your real concern is memory thrashing "virtual memory will be of no use due to swapping overhead" , then this is what you should be looking for, rather than trying to infer or guess A more useful metric would be page faults per unit of time. It just so happens that there are performance counters for this too. See, for example Evaluating Memory and Cache Usage.
