Note: If you are using TIBCO Scribe Online, installing multiple Agents on the same computer can impact memory and performance. Perfmon is included with Windows operating systems. IMPORTANT NOTE: The “Memory” colums displayed by default in XP is diferent to that in Vista\Windows 7. Details Use Perfmon to log memory usage over time when you are troubleshooting an issue with either TIBCO Scribe Online Agents or TIBCO Scribe Insight. However, that kind of thing has already been done for you. On the left, choose which counters to add and click Add >. Click the green '+' sign near the top of the Performance Monitor window to bring up the Add Counters window. You will then see the Performance Monitor pop-up. You will need to consider using WMI to tally the total RAM in a server, then totaling the amount of used RAM versus free RAM, storing that data as it is collected, and then presenting it in a pretty way. Type perfmon at the Run command prompt and click Ok. Working Set (Memory) within Task Manager shows as “ Working Set” within Perfmon. Sadly, there is no default Performance Monitor counter that does this. With that said, some of the performance counters can provide some clues such as MemoryAvailable MBytes, MemoryPool Nonpaged Bytes, MemorySystem Cache. The perfmon equivalent is “ Working Set – Private” Task Manager (by default) shows “ Memory (Private Working Set)“. Thing are much better in more recent Windows OS variants – MS have brought the definitions used in Task Manager / Perfmon in-line (and dramatically improved perfmon!) “ VM Size” within Task Manager is “ Private Bytes” within perfmon The perfmon equivalent is “ Working set” (selectable within “Processes”) The performance monitor is available from Tools->Performance Monitor menu and it shows some memory and usage statistics. Task Manager (by default) shows “ Mem Usage“. In some cases Task Manager and Perfmon use different names when referring to the same thing – this can make it tricky to know which counters to select! However – to collect data over time or view “trends”, it’s often necessary to use Performance Monitor (perfmon) Task Manager provides a quick way to get a “point in time” view of how much memory a process is using.
