Metric | Description | Unit |
Memory | Free JVM memory | Megabyte |
Direct | Free direct memory | Megabyte |
Mapped | Used mapped memory | Megabyte |
OpenFileDesc | On Unix only. The number of file descriptors opened by the Universal Messaging server process | |
EventMemory | JVM memory consumed by events | Megabyte |
Disk | Free disk space in UM data directory | Megabyte |
CPU | Recent CPU usage for the JVM process in percent. Valid values are from 0 to 100 percent. | % |
Scheduled | Number of tasks in the internal scheduler | |
Queued | Number of total tasks currently queued in all thread pools. A value of zero indicates that at this moment in time there were no tasks waiting for a thread. | |
Connections | Active Universal Messaging connections | |
BytesIn | Total bytes received for currently active Universal Messaging connections | byte |
BytesOut | Total bytes sent for currently active Universal Messaging connections | byte |
Published | Total number of published events | |
Consumed | Total number of consumed events | |
QueueSize | The count of requests/responses awaiting processing that have arrived from other nodes in the cluster (inbound from the cluster). On the master node: the requests are from slave nodes, which forward requests from their locally attached clients to the master node. the responses are from slave nodes, to confirm that the slave nodes have processed client requests previously propagated by the master node. On slave nodes: the requests are from the master node, which propagates (a) requests from clients attached locally to the master, and (b) requests received by the master from clients attached to slave nodes. The propagation goes to all slave nodes in the cluster. the responses are from the master node, to confirm that the master node has processed client requests that were originally sent by the current slave node. A continuously growing size of this queue indicates that the server is not able to process the cluster messages at the rate they are arriving. This value is only present if the node is part of a cluster. | |
ClientsSize | The count of local client requests awaiting processing by the current node. On the master node, requests from locally attached clients will be processed on the master node, then propagated to the slave nodes in the cluster. On slave nodes, requests from locally attached clients will NOT be processed locally but instead will be forwarded to the master for processing. A continuously growing value of this metric indicates that the server is not able to process and send the client requests to other cluster nodes at the rate these requests are received. This value is only present if the node is part of a cluster. | |
CommQueueSize | The count of all requests/responses waiting to be sent to the other nodes of the cluster. A continuously growing value of this metric indicates that writing data to the other cluster nodes over the network is slower than the rate at which messages are processed and queued. This indicates a network problem at the data layer level rather than a processing problem on the node. This value is only present if the node is part of a cluster. |
