Windows Memory Graph (2000/2003)

Phobos182 · Post by **Phobos182** » Thu Aug 25, 2005 9:59 am

After searching the forums for a memory graph, I found a couple that show way too much information. Also some that are very hard to read quickly. Since I dont want to spend a minute or so looking at a graph to determine if there is a problem, I created a new graph.

What I wanted to accomplish was a few things

- Is the server utilizing memory greater than it has physical memory?
This would let me know that if I turned off paging, the system would crash. If it was under by a lot, I could turn off paging with little to no problems, and gain some performance increase.

- Is the server utilizing a lot of virtual memory?
If so, I could decrease the paging file size, and have it use the physical memory.

The graph is pretty simple. It shows you the virtual memory total, and virtutal memory used. Also the total physical memory installed, and the total physical memory used. But what it also does it total the virtual memory used with the physical memory used to determine the total amount of memory used by the server. If you compare this line to the total physical memory, you can see if the server even needs paging files, or needs more memory perhaps.

There are a couple of examples below. The first, the 'magic orange line' exceeds the total physical memory. If i turned off paging, it would crash.

The third shows a server that's seriously getting it's ass kicked. The total memory is almost double the amount of physical memory installed. At one point it entirely runs out of physical memory, and goes to swap hardcore.

Hope you enjoy it. It took a while to make.

Here is the script used to grab the data. Save this to your <cacti path>/script directory.

Download & Import the template in the first post above, and you should be set to start graphing.

Thanks to Lit for providing it in his memory graph post.

Feel free to make a SNMP version of this script

WMI is only usable when cacti runs on Windows, and this is a nice script.

All that data is unfortiantly not available via SNMP, hence the WMI script.

Have a look at SNMP-Informant which gives some memory information, http://www.wtcs.org/informant/functionality.htm has OID tree of the standard (free) agent.

Right, I know about that. My point was natively, windows does not provide snmp OID's for that. It does via WMI though.

This is a nice graph, informative and visually appealing. However, if you are monitoring a remote system, your poller needs to be running as a user with network rights, and probably administrative ones, at that.

This is imposed by WMI, presumably on the remote end.

And that can be fixed my adding the cacti user in Local Security Policy and dcomcnfg.

can more detailed?
i can't get data from remote host.

Thanks for the help BSOD.

Can somebody export this for Cacti 8.6g?

FYI: I'm working on an SNMP-Informant Version of this graph. Please stay tuned during the next week or so Linux Users.

That would be great! Thank you

I had been using this get memory graph but it stopped functioning when i switched to cactid polling. Is there something different i should do to use it with cactid and not cmd.php?

With cactid polling i get the following:

12/06/2005 12:31:09 PM - CACTID: Poller[0] Host[21] DS[354] WARNING: Result from SCRIPT not valid. Partial Result: ...
12/06/2005 12:31:09 PM - CACTID: Poller[0] Host[21] ERROR: Empty result [server54-ccc.cpsb.org]: 'perl.exe C:/Cacti\scripts\w32_query_os.pl 10.54.0.249 get FreePhysicalMemory,FreeSpaceInPagingFiles,FreeVirtualMemory,MaxProcessMemorySize,SizeStoredInPagingFiles,TotalVirtualMemorySize,TotalVisibleMemorySize'
