8.4 cepdispeng

Name

cepdispeng - CEP engine information display


Format
cepdispeng [-i] [-a | -e engineName]

Function description

This command displays the basic information or the operation status of a CEP engine.


Arguments
-i

This option is used to display the basic information of a CEP engine.

If this option is not specified, the operation status of the CEP engine will be displayed.

The table below explains the items displayed:

Basic information

Item name

Content

Displayed?

engineId

CEP engine name

Yes

eventtype

Development asset ID of the deployed event type definition

Conditional

rule

Development asset ID of the deployed rule definition

Conditional

master

Development asset ID of the deployed master definition

Conditional

listener

Development asset ID of the deployed SOAP listener definition

Conditional

Yes: Always displayed

Conditional: Displayed if the development asset has been deployed

Point

If two or more development assets of the same definition are deployed, they are displayed in multiple lines.


Operation status

Item name

Content

Displayed?

engineId

CEP engine name.

Yes

port

Port number for socket communication (socket adapter port).

Conditional (*1)

socket

Number of simultaneous connections in socket communication.

Conditional (*1)

status_filter

Status of the CEP engine (high-speed filter).

RUN: Running normally

STARTING: Starting

STOP: Stopped

STOPPING: Stopping

ABNORMAL: Abnormal

Yes

status_cep

Status of the CEP engine (complex event processing).

RUN: Running normally

STARTING: Starting

STOP: Stopped

STOPPING: Stopping

ABNORMAL: Abnormal

Yes

inEvent_filter

Number of input events for the CEP engine (high-speed filter).

Indicates the number of events input to the high-speed filter. Displays a cumulative value from when the CEP engine started.

Conditional (*2)

inEvent_cep

Number of input events for the CEP engine (complex event processing).

Indicates the number of events input to complex event processing. Displays a cumulative value from when the CEP engine started.

Conditional (*3)

outEvent_filter

Number of output events for the CEP engine (high-speed filter).

Indicates the number of events sent to complex event processing. Displays a cumulative value from when the CEP engine started.

Conditional (*2)

outEvent_cep

Number of output events for the CEP engine (complex event processing).

Indicates the number of events sent to a user-developed Web service. Displays a cumulative value from when the CEP engine started.

Conditional (*3)

logging_filter

Number of loggings for the CEP engine (high-speed filter).

Conditional (*2)

logging_cep

Number of loggings for the CEP engine (complex event processing).

Conditional (*3)

heap_filter

Java heap usage and area size for the CEP engine (high-speed filter).

Displayed in the following format:

Java heap usage (bytes)/area size (bytes)

Conditional (*2)

heap_cep

Java heap usage and area size for the CEP engine (complex event processing).

Displayed in the following format:

Java heap usage (bytes)/area size (bytes)

Conditional (*3)

useMemory_filter

Memory usage of CEP engine (high-speed filter) processes (kilobytes).

Conditional (*2)

useMemory_cep

Memory usage of CEP engine (complex event processing) processes (kilobytes).

Conditional (*3)

countRule_filter

Number of rules applied to the CEP engine (high-speed filter).

Conditional (*2)

countRule_cep

Number of rules applied to the CEP engine (complex event processing).

Conditional (*3)

countListener

Number of applied listeners.

Indicates the number of SOAP listener definitions applied to the CEP engine (complex event processing).

Conditional (*3)

Yes: Always displayed

Conditional: Displayed in the following cases:

*1: If socket communication is being used (if a socket adapter is being used by the CEP engine)

*2: If the CEP engine (high-speed filter) is running normally (if status_filter is "RUN")

*3: If the CEP engine (complex event processing) is running normally (if status_cep is "RUN")


-a

This option is used to display information on all configured CEP engines.


-e engineName

Specify the name of the CEP engine for which information is to be displayed.

If only one CEP engine has been configured, this option can be omitted.

If this option is omitted, and if there are two or more configured CEP engines, an error message will be output and the display will fail.


End status

The following status codes are returned:

0

Normal end

8

Abnormal end
