       Device Configuration

Device Tree View

For each device listed in the Device Tree View (on the left side of the main window), you can manually configure scan parameters, to fine tune data acquisition. You can easily search for Devices or Groups, managing your Network. Select a Device and you can see below information like Name, Description and Enabled Probes.

Device Toolbar

To manually add a device, use the "Add Device" button on Device toolbar, or right-click any empty space on Device Tree View and choose "Add Device" from the context menu. To edit the properties of an already added device, you can select the device and then use the "Device Properties" button on the toolbar, right-click the device and choose "Device Properties" from the context menu or double-click the device. Both options (adding a device or editing its properties) will display a detailed configuration dialog box:

General

Device Configuration Dialog

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

IP Address: Configured IP address for the specified device.

Device Name/Description: The device Name and a short description of this device. You can automatically fill these fields clicking on "Fetch Name".

Community: SNMP community for OID reads (acts like a SNMP device password).

SNMP Version: SNMP protocol version to be used for data acquisition. Notice that the SNMPv3 authentication leaves the SNMP communication very slow.

SNMP V3 Auth Username: The username used to access SNMP V3 devices.

SNMP V3 Auth Password: The password used to access SNMP V3 devices.

SNMP V3 Auth Algorithm: The algorithm to cryptograph the login in SNMP V3 device connection.

WMI Auth Username: The username used to access WMI devices. Notice that this user must have administrator privileges to access the devices correctly.

WMI Auth Password: The password of WMI Username.

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

Tree Map Weight: Define the weight of the device on Tree Map View. See more.

Refresh Settings

Device Configuration - Refresh Settings

SNMP Refresh Settings:

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

Group OID Reads: Number of SNMP variables to be read in the same SNMP call.

Refresh Rate: Device refresh rate in milliseconds. For SNMP, the minimum value is 5000 ms.

Trap Hold Time: Amount of time to hold before resetting a trap item.

Some device settings are critical. This means that they may be changed only for optimization purposes. Also some devices do not support scanning too many variables in the same SNMP call, so you might have to change the Group OID Reads configuration to use such devices.

WMI Refresh Settings:

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

Refresh Rate: Device refresh rate in milliseconds. For WMI, the minimum time is 1000 ms.

Network Health

Device Configuration - Network Health

These options are found in Network Health tab for three different SNMP Predefined Probes:

Utilization Adjustment: percentual interface utilization. Default baseline value is 5, while threshold default value is 35.

Transmission Effectiveness Adjustment: percentual interface transmission integrity.Baseline and threshold defaults values are 95 and 80 percent respectively.

Non-Unicast Rate Adjustment: amount of broadcast packets through this interface in packets/second. XRatel recommends the values 256 and 512 for baseline and threshold respectively.

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

General Health: Indicates whether this device is used in system health calculation. Uncheck this box to make system health independent of this device health.

Computer Health

Device Configuration - Computer Health

These options are found in Computer Health tab for three different WMI Predefined Probes:

CPU Usage Adjustment: percentual CPU utilization. Default baseline value is 40,  while threshold default value is 90.

Physical Memory Usage Adjustment: percentual Physical Memory utilization. Baseline and threshold defaults values are 30 and 60 percent respectively.

Disk Usage Adjustment: percentual Disk utilization. XRatel recommends the values 50 and 80 for baseline and threshold respectively.

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

General Health: Indicates whether this device is used in system health calculation. Uncheck this box to  make system health   independent of this device health.

Health Definition

Health Analyst Settings Limits

You can define Health status limits in Health Analyst Limits tab. In this tab, you define the Yellow limit and the Red limit in percents. Yellow limit always is greater than Red limit. By default, the Yellow limit is 40% and the Red limit is 10%. If the Probe was over than yellow limit, the status Probe would be green, if the Probe was between the Yellow limit and the Red limit, the Probe would be Yellow, and if the Probe was under the Red limit, the status Probe would be Red.
