Re: [hobbit] BBWin Virtual Memory



I use Hobbit 4.2 as my production server, and I don't have any Windows clients pointing at Xymon right now. I am currently using BBWin in local configuration mode because it's going to be a sizable time investment to switch. I am waiting until I am ready to replace the production server and upgrade to Xymon before changing to central config mode. I hope that these possible differences don't make my installation so different as to make what I'm saying useless. If so, hopefully someone who knows will speak up.

The virtual (shows up as "actual" on the graph), as you have noticed, is useless. On all of my systems, it shows 32 used out of 2047. The physical memory (shows up as "real" in the graph) is actual physical memory, but it's *mostly* a useless figure as well. The page value (shows up as swap in the graph) is the one that seems to really matter. It is the overall usage of both physical memory and the pagefile. Be aware that if the ratio of real memory to pagefile on your systems varies widely (as it does in my network), you will end up needing very different alarm thresholds for each of your systems. Adjusting that ratio is the only way I've found to bring parity, but the biggest problems tend to be on the older systems, which usually don't have enough disk space to accomodate a change.

Hi.

I am posting this here, since the BBWin project seems (even more) dead.

I have been trying to figure out what the different values in BBWin's memory test are. During this, I noticed that the "Virtual" size is shown as 2047MB for all our Windows clients, regardless of the real size of the virtual memory. Has anyone else noticied this?

Also, it seems like the "Real" memory indicator mentioned in the help file does not work at all.

What alarm levels do you people use for Memory in BBWin? We have previously only been using "Virtual" for alarms, but with the recent discovery that seems like a very bad idea.
