State at Time

Screenshot

On the Monitoring dashboard the State at Time tab displays an overview of the state of the system for any time in the past – useful for interrogating the system state before or during a process or system failure.

Its league tables

can be filtered by Date, Lookback (in seconds), Host Group, Alias and PID. Lookback averages data values over the lookback period. Specify the filter values and click Submit to update the display.

Sort table rows by any column by clicking on its heading.

Process CPU Memory League Table

Screenshot

This table displays details of the processes using the most CPU and memory. (Processes using nominal levels are ignored.)

Information displayed:

column content
Time Time the snapshot was taken. The frequency of updates is controlled by the Lookback seconds specified in the filters
SignalHost Name of the host group
PID Process ID
Name Type of process, e.g. q, Java
UserName User running the process
CPU Percentage of CPU being used by the process
Memory Amount of memory, in Mb, being used by the process
lastCore Last CPU core the process was recorded to have run on
alias Identifier for the connection: in many cases, a work station to the Tomcat, for which you will see a machine name

Network Connections League Table

sendQ Send queue size
localaddr Local address
spid Process ID associated with the queues
localport Local port connection point
remoteaddr Remote address
remoteport Remote port connection point
alias A combination of fields to identify the connection to the process instance displayed: in many cases, a work station to the Tomcat, for which you will see a machine name
state State of the connection, usually established
processAlias Process connection name or an alias that it is known by

Server Memory League Table

This table displays server memory stats for all servers in the system – useful for identifying the servers using the most memory.

The information displayed:

column content
Time Time memory server table was updated
signalHost Name of the host
UsedPercent Amount used
memTotal Total memory (Mb)
actualFree Actual free memory (Mb) including buffer cache
actualUsed Actual amount of memory used (Mb), including allocated cache
swapTotal Size of the swap memory partition (Mb), the virtual memory stored on disk
swapUsed Amount of swap memory used (Mb)

CPU Core League Table
