Represents runtime information of a cluster. Apart from obvious statistical value, this information is used for implementation of load balancing, failover, and collision SPIs. For example, collision SPI in combination with fail-over SPI could check if other nodes don't have any active or waiting jobs and fail-over some jobs to those nodes. More...

Node metrics for any node can be accessed via IClusterNode.GetMetrics method. Keep in mind that there will be a certain network delay (usually equal to heartbeat delay) for the accuracy of node metrics. However, when accessing metrics on local node the metrics are always accurate and up to date.

This value represents a setting of the heap memory for Java VM and is not a sum of all initial heap values for all memory pools.
|
get |
This amount of memory is not guaranteed to be available for memory management if it is greater than the amount of committed memory. The JVM may fail to allocate memory even if the amount of used memory does not exceed this maximum size.
