Java Application Status Test

Sometimes, Java applications running on SAP BTP Neo environment may be stopped for maintenance or for debugging activity. During such times, users will not be able to access the application. To proactively figure out the Java applications that are stopped in a target environment and ensure better user experience, administrators need to constantly keep a vigil on the status of the Java applications running on the target environment. The Java Application Status test helps administrators in this regard!

This test monitors the Java applications running on the target environment and for each Java application, this test reports the current status. Using this test, administrators can easily isolate the applications that are currently stopped and initiate remedial steps to start the applications before end users start complaining.

Target of the test : A SAP BTP Neo Environment

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for each Java Application in the target SAP BTP Neo Environment.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed

Host

Host name of the server for which the test is to be configured.

PortNo

Enter the port to which the specified host listens. By default, this is 10002.

Subaccount

In SAP Cloud Platform Cockpit, one user account will have multiple subaccounts. So you can mention any one of the subaccount name in the Subaccount text box. To know how to determine the Subaccount, refer to Identifying the API Endpoint URL and Subaccount topic in Pre-requisites for Monitoring SAP BTP Neo Environment.

User

For collecting the metrics, specify the Username in the User text box. The Username here refers to the Client ID created in SAP Cloud Platform Cockpit. To know how to create such a user (Client ID) in SAP Cloud Platform Cockpit, refer to Registering the eG Agent as an API Client topic in Pre-requisites for Monitoring SAP BTP Neo Environment.

Password

Specify the password in the Password text box. The Password here refers to the Client Secret created in SAP Cloud Platform Cockpit. To know how to create Password (Client Secret) in SAP Cloud Platform Cockpit, refer to refer to Registering the eG Agent as an API Client topic in Pre-requisites for Monitoring SAP BTP Neo Environment.

Confirm Password

Confirm the password by retyping it here in the Confirm Password text box.

DD Frequency

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD frequency.

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Application State

Indicates the current state of Java applications running on the target environment.

 

The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure Value

 Numeric Value
OK 0
Stable 1
Warning 2
Unstable 3
Critical 4

Note:

By default, this measure reports the Measure Values listed in the table above to indicate whether/not the status of java applications is stable.

The detailed diagnosis of this measure provides the stopped java application process details like the account name, create date, updated date, application url, runtime name, argument and version.

Total processes

Indicates the total number of Java application processes running on the target environment.

Number

Pending processes

Indicates the number of Java application processes that are pending.

Number

A low value is typically desired for this measure.

Starting processes

Indicates the number of Java application processes that are in starting stage.

Number

 

Started processes

Indicates the number of Java application processes that started.

Number

 

Stopping processes

Indicates the number of Java application processes that are in stopping stage.

Number

A low value is typically desired for this measure.

Stopped processes

Indicates the number of Java application processes that stopped.

Number

A low value is typically desired for this measure.

The detailed diagnosis of this measure if enabled, detailed diagnosis provides details about the stopped process like the process Id, display name, id, state, version, expiry date and availability zone.
