On the PRTG Status page, I can find, among many other things, a lot of parameters regarding the core system memory. What do they mean?

This article applies to PRTG Network Monitor 19 or later
| Important: The following article will no longer be updated. For up-to-date information, see the PRTG Manual: System Status. |
Managing the memory of your systems is essential for almost everything. This is why prompt information about your system memory usage is always useful. Instead of searching through your whole system to collect the PRTG-related data you need, PRTG has information ready for you.
Note: The information you get refers to the PRTG core server. If you run a PRTG cluster, the information refers to the cluster node you are currently logged in to.
To see the memory usage information, go to Setup | PRTG Status in the PRTG web interface and click Core System Memory.
PRTG shows the following parameters:
| # | Parameter | Description |
|---|---|---|
| 1 | Committed | The amount of memory that your system commits to the PRTG core server system. |
| 2 | Allocated | The amount of memory that the PRTG core server system is currently using. |
| 3 | Unused | The amount of allocated memory that the PRTG core server system is currently not using. |
| 4 | Free Physical | The amount of free memory that is currently available on the PRTG core server system's physical memory. |
| 5 | Total Physical | The total amount of memory that is provided by the PRTG core server system's physical memory. |
| 6 | Free Pagefile | The amount of free memory that is currently available in your system’s pagefile(s). |
| 7 | Total Pagefile | The total amount of memory of your system’s pagefile(s). |
| 8 | Free Virtual | The amount of free memory that is available in the PRTG core server system's virtual memory. |
| 9 | Total Virtual | The total amount of memory of the PRTG core server system's virtual memory. |
| 10 | Free Effective | The effective amount of free memory on your PRTG core server system. This corresponds to Free Pagefile. |
| 11 | Object Count | The number of PRTG-internal data structures, also known as tree nodes, for example, the number of sensors + users + reports. |
| 12 | BaseInstance | The amount of memory that is used for the tree node Instance. |
| 13 | BaseAccess | The amount of memory that is used for the tree node Access Rights. |
| 14 | BaseHistory | The amount of memory that is used for the tree node History of Configuration Changes. |
| 15 | BaseCurrent | The amount of memory that is used for the tree node Current Configuration Information. |
| 16 | BaseData | The amount of memory that is used for the tree node Configuration Data. |
| 17 | BaseChannel | The amount of memory that is used for the tree node Channel Settings. |
| 18 | BaseTrigger | The amount of memory that is used for the tree node Trigger. |
| 19 | BaseIDs | The amount of memory that is used for the tree node IDs. |
| 20 | BaseLookup | The amount of memory that is used for the tree node Sensor Lookups. |
| 21 | BaseCheck | The amount of memory that is used for the tree node Check Requests. |
| 22 | BaseDeplist | The amount of memory that is used for the tree node Dependency List. |
| 23 | Datasets | The amount of memory that is currently used for datasets, like for graphs. |
| 24 | State | The amount of memory that is currently used for user-specific datasets. |
| 25 | Interface | The amount of memory that is currently used for tree node-specific table objects. |
| 26 | IndexCache | The amount of memory that is currently used for the index dataset cache that is particularly important in a cluster. |
| 27 | TreeTotal | The total amount of memory that is used by the PRTG tree. |
| 28 | DatasetCache | The amount of memory that is currently used for the dataset cache, in particular regarding historic data. In parentheses, you see the number of datasets that are saved in the cache. |
| 29 | StorageSystem | The amount of memory space that is currently used for the storage system. |
| 30 | Sessions | The amount of memory that is currently used for sessions. A user can activate more than one session. In parentheses, you see the number of currently activated sessions. |
| 31 | StateObjects | The number of user-specific state objects that are found in the PRTG core server system's memory. |
