Resource statistics data: Global Cache
Learn about the data that is returned for the Global Cache resource type when you activate resource statistics collection.
You can view these statistics in the web user interface, or you can write a program that subscribes to a publication (single XML message) that returns this data. For an example of the publication message, see Example XML output.
The global cache resource manager contains data about the interactions between message flows in a named integration server and the cache. Statistics are available for all activity in the embedded global cache and external WebSphere® eXtreme Scale grids. One line of statistics is shown for each configurable service that is used to connect to an external grid.
| Measurements | Description |
|---|---|
| ConnectionFailures | The number of failed attempts to connect from this integration server to the named cache. |
| Connects | The number of successful attempts that were made from this integration server to the named cache. |
| FailedActions | The number of failed map operations by message flows in this integration server on the named cache. |
| MapReads | The total number of read operations that were completed by message flows in this integration server on the named cache. |
| MapRemoves | The total number of remove operations that were completed by message flows in this integration server on the named cache. This count is incremented by removing or updating an entry. |
| MapsUsed | The total number of maps that are used by message flows in this integration server in the named cache. This count is incremented each time a different map name is used in this integration server. |
| MapWrites | The total number of write operations that were completed by message flows in this integration server on the named cache. This count is incremented by putting or updating an entry. |
| Name | The name of the WebSphere eXtreme
Scale grid for this cache. For
the embedded global cache, this name is "WMB". For an external grid, this name consists of the name of
the configurable service that is used to connect to the grid, and
the name of the grid itself. For example, if you use a configurable
service called "xc10" to connect to a grid called "Grid1", this name
property has the value |
| TotalMapActions | The total number of map operations that were completed by message flows in this integration server on the named cache. This number includes reads, writes, removes, and key checks. |
