App Volumes - Manager Logs Test

This test periodically scans the event logs of the target VMware App Volumes Manager for errors/warnings that were registered for each event type and promptly captures and reports those error/warning messages. In addition, this test reveals the number of jobs that were delayed for each event type, the connections that were successful and the connections that failed. Using this test, administrators can identify the connections of the event type that were too slow.

Target of the test : A VMware App Volumes Server

gent deploying the test : An internal/remote agent

Outputs of the test : One set of results for the events generated for each event type on the target VMware App Volumes Manager being monitored

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The host for which the test is to be configured.

Port

The port at which the specified Host listens to. By default, this is set to 3443.

AppVol User

By default, the eG agent uses the RESTful APIs to collect the metrics from the target VMware App Volumes Manager. To be able to connect to the RESTful API, the eG agent should be configured with the credentials of a user belonging to an active directory group that is vested with the Administrators (Read only) rights. Specify the credentials of such a user in this text box. To know how to assign the Administrators (Read only) role to an active directory group, refer to Enabling the Administrators (Read only) role.

AppVol Password

Specify the password that corresponds to the AppVol User.

Confirm Password

Confirm the password by retyping it here.

WebPort

By default, in most virtualized environments, the VMware App Volumes Manager listens on port 3443 irrespective of being SSL-enabled or not. This implies that while monitoring the target VMware App Volumes Manager , the eG agent, by default, connects to port 3443 of the VMware App Volumes Manager to pull out metrics. Accordingly, the WebPort parameter is set to 3443. In some environments however, the default port 3443 might not apply. In such a case, against the WebPort parameter, you can specify the exact port at which the VMware App Volumes Manager in your environment listens so that the eG agent communicates with that port.

SSL

Set the SSL flag to Yes, if SSL (Secured Socket Layer) is to be used to connect to the target VMware App Volumes Manager, and No if it is not.

Log File Path

Here, specify the path to the log file of the target VMware App Volumes Manager. By default, this is set to none. This implies that the eG agent will automatically collect the required metrics from the log file available in the default log file location. If the target VMware App Volumes Manager is installed in a different location, then, you have to explicitly specify the location of the log file in this text box. For e.g., if you have installed the target VMware App Volumes Manager in C:/, then, your specification should be C:/CloudVolumes/Manager/log.

DD For Info

By default, this flag is set to No indicating that this test will not report detailed diagnosis for the Information count measure. If you wish to view the detailed diagnosis of the Information count measure, set this flag to Yes.

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 suite 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

Information count

Indicates the number of information messages generated for this event type during the last measurement period.

Number

A change in the value of this measure may indicate infrequent but successful operations performed by one or more applications.

The detailed diagnosis of this measure if enabled, lists the Event Time, Process ID, Process Type and the Message received.

Warning count

Indicates the number of warning messages generated for this event type during the last measurement period.

Number

A high value of this measure indicates problems with the broker that may not have an immediate impact, but may cause future problems in the VMware App Volumes Manager.

The detailed diagnosis of this measure lists the Event Time, Process ID, Process Type and the Message received.

Error count

Indicates the number of error messages received for this event type during the last measurement period.

Number

A very low value (zero) indicates that the system is in a healthy state and all applications are running smoothly without any potential problems.

An increasing trend or high value indicates the existence of problems like loss of functionality or data in one or more applications.

The detailed diagnosis of this measure lists the Event Time, Process ID, Process Type and the error message received.

Active requests

Indicates the number of active requests received for this event type during the last measurement period.

Number

 

Delayed jobs

Indicates the number of jobs of this event type that were delayed during the last measurement period.

Number

A low value is desired for this measure.

The jobs may be delayed due to various reasons such as unavailable background work processes, scheduling issues between the originating server and target server, other dependencies etc.

Connection success

Indicates the number of connections that were successful for this event type during the last measurement period.

Number

Compare the value across event types to figure out the event type for which most of the connections were successful.

Connection failed

Indicates the number of connections that failed for this event type during the last measurement period.

Number

A low value is desired for this measure.

Compare the value of this measure across the event types to figure out the event type for which maximum number of connections failed.

Average connection success time

Indicates the average time taken for the connections to be successful for this event type during the last measurement period.

Seconds

A steady increase in the value of this measure is an indication that connectivity issues prevail. Administrators should promptly check the connections from time to time to avoid such issues.
