SIOS Jobs Details Test

For ease of use and configuration, the SIOS DataKeeper manages mirrors through an entity called a job. A job is a logical grouping of related mirrors and servers. This feature allows you to create a job for complex repetitive tasks and run the tasks quickly from the SIOS DataKeeper user interface. If a job does not run the tasks quickly due to any fatal errors, the mirrors grouped under that job will experience the slowdown and processing-bottleneck. As a result, the synchronization between the mirrors will be paused temporarily or broken forever. To avoid such unpleasant events, it is necessary that the jobs should be continuously monitored. This where the SIOS Job Details test helps administrators!

This test auto-discovers the jobs created on the SIOS DataKeeper, and reports the current status of each job. This way, this test proactively is alerted to the administrators. In addition, this test also reveals the type of mirroring that each job performs and the disk space allocated for each job.

Target of the test : A SIOS DataKeeper

Agent deploying the test : An internal agent

Outputs of the test : One set of results for each job created on the SIOS DataKeeper 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 number at which the specified host listens to.
EM Command Path	EMCMD utility that ships with SIOS DataKeeper provides users with a command line method to manipulate the mirror. The EMCMD scripts run in situations where the “normal” validation rules are not applicable. EMCMD utility does not perform the same kinds of sanity checks that the user would experience using the SIOS DataKeeper User Interface. EMCMD utility simply passes commands to the SIOS DataKeeper Replication service allowing the service to make any decisions. Sometimes, the eG agent may use the EMCMD to collect metrics from the mirrors. For this purpose, the eG agent auto-discovers the EMCMD.exe file in the SIOS DataKeeper install directory and report metrics. If the EMCMD.exe file is installed in a different location, then you can explicitly specify the exact location of the install directory here. For example, c:\programs\SIOSData.
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

State

Indicates the current status of this job.

The values that this measure can report and the numeric values they indicate have been listed in the table below:

Measure Value	Numeric Value
Invalid	-6
No mirror	0
Mirroring	1
Mirror is resyncing	2
Mirror is broken	3
Mirror is paused	4
Resync is pending	5

Note:

By default, this measure can report the Measure Values mentioned above while indicating the current status of each job. However, the graph of this measure is indicated using the numeric equivalents.

The detailed diagnosis of this measure reveals the name of the server and source volumes and the name and IP address of the source and target systems.

Mirror type

Indicates the type of mirroring performed by this job.

The values that this measure can report and the numeric values they indicate have been listed in the table below:

Measure Value	Numeric Value
No Mirror	0
Synchronous	1
Asynchronous	2

Note:

By default, this measure can report the Measure Values mentioned above while indicating the type of mirroring performed by each job. However, the graph of this measure is indicated using the numeric equivalents.

Disk space

Indicates the amount of space allocated for this job.
