For each computer listed in the Computer List (on the left side of the main window), you can manually configure scan parameters, to fine tune data acquisition. You can easily identify which computers are active or inactive for real-time monitoring.

Computer List View

To manually add a computer, use the Add Computer button on the toolbar, or right-click any empty space on the computer view and choose Add Computer from the context menu. To edit the properties of an already added computer, you can select the computer and then use the Computer Properties button on the toolbar, or right-click the computer and choose Computer Properties from the context menu.

To add a group, you can use the button "Add Group" on the toolbar, or right-click any empty space on computer list and choose "Add Group" from the context menu. To add a computer to a specific group, you add the computer to the computer list and drag it into the group or right-click into a group and chose Add Computer.

Computer Toolbar

Both options (adding a computer or editing its properties) will display a detailed configuration dialog box:

Computer Configuration Dialog

You can customize the following computer settings in the General Tab:

IP Address: Configured IP address for the specified computer.

Computer Description: A short description of this computer.

WMI Auth Username: Username to be used for authentication, if needed.

WMI Auth Password: Password to be used for authentication, if needed.

Read Timeout: Amount of time (in milliseconds) to wait for a response from the computer.

Refresh Rate: Computer refresh rate in milliseconds.

General Health: Indicate if this computer will be in the system health calculation.

Scan Active: Defines whether the computer will be monitored or not.

History Status tags: Enable device to status tags be showed in Health Analyst.

For each health tag, two calculation ways are possible: by baseline and threshold adjustment or using the sensibility adjustment.

Health calculation example

You can configure these options by two ways:
 

Condition based: Select the desired value manually. Select Condition Based Bias Adjustment option and then manage baseline and threshold boxes. Baseline indicates the desired value of the tag while threshold is the desired tolerance for it.

Sensibility based: The health calculation is made using the real value of the tag and a multiplier. Select Sensibility Based Adjustment and then, select the desired multiplier using the multiplier bar.

These options are found in Health Calculation tab for three different Performance tags:
 

CPU Usage Adjustment: percental CPU utilization. Default baseline value is 30, while threshold default value is 70.

Memory Usage Adjustment: indicates the percental memory utilization. XRatel recommends the values 30 and 60 for baseline and threshold respectively.

Disk Usage Adjustment: percental disk usage. Baseline and threshold defaults values are 40 and 80 percent respectively.

The Reset to Defaults button resets all values to default values.

Health Calculation Settings

You can define health limits in Health Analyst's Limits tab. In this tab, you define the Yellow limit and the Red limit in percent. Yellow limit always is greater than Red limit.  By default, the Yellow limit is 40% and the Red limit is 10%. If the tag value is over than yellow limit, the status tag will be green, if the tag is between the Yellow limit and the Red limit, the tag will be Yellow, and if the tag is under the Red limit, the status tag will be Red.

After editing or adding the computer, just click on the OK button to close the Computer Settings dialog and update the computer settings. If you want to discard all changes, just click on Cancel to close this dialog.
