Tools

In the “Tools“ menu you can find various tools allowing you to access devices

in your network using Ping, graphical user interface, CLI, SNMP browser or

the HiDiscovery V1 Scan.

8.13.1 Dashboard

The Industrial HiVision “Dashboard“ is a valuable fault-finding tool which

allows an administrator to view the network statistics and useful information

about the performance of the network in real time.

Industrial HiVision allows you to create multiple dashboards with various

information, then preview the dashboards as a slide show. The function also

allows you to save and load the dashboard layouts.

The main window contains a time slider. The time slider allows you to adjust

how long the slide show displays each page.

When you close the Industrial HiVision application, the application saves the

size and position of the dashboard. The application also saves other active

dashboard options such as the full screen mode, timer slider status, and the

play or pause status.

 Widget Size

The dashboard allows you to increase or decrease the size of widgets.

To increase the size of a widget, verify that you have cells free on the right

or below the widget that you wish to enlarge. If there are no free cells

available, then add the required number of cells using the “Grid“ buttons.

Highlight the widget you wish to enlarge. Using the “Widget Size“ plus “+”

button increases the size of the widget. The size of the widget increases

one cell each time you click the plus “+” button.

 Properties Button

Some widgets allow you to configure which parameters to monitor. To

specify which parameters the widget monitors click the “Properties“

button, then enter the values in the “Parameters“ dialog. The widgets also

allow you to drag parameters from various tabs in the GUI or the folder

frame and drop them into the widget.

The following widgets allow you to specify parameters to monitor:

 “Connection Status“

 “Moving Avg Ping Response Time“

 “Numeric Property“

 “Top 10 Moving Avg Response Time“ (no drag and drop)

 Viewing Modes

Industrial HiVision allows you to view a slide show of the dashboard

pages using the following methods.

 When you click the “Full Screen” button

, the dashboard changes

to the full screen mode and the slide show is in the “Pause” mode.

 Dashboard Order

When you have multiple dashboards Industrial HiVision allows you to

display the dashboards in any order. When you have multiple dashboards

or the selected dashboard is not at the top of the list, the move up button

is active. The move up button moves the selected dashboard one step up.

 Device Summary Widget

The widget displays a summary of the devices contained in the entire

project. The summary displays devices according to the state of the

device. The widget only displays the state of managed and licensed

devices.

421

References

Tools > Dashboard

Industrial HiVision includes the device and copies of devices in the

summary. When you add a copy of a device to Industrial HiVision, the

“Device Summary“ widget counts the device twice. The reason that the

widget counts the device twice is because the status of the copy can differ

from the original. The “Device Summary“ widget excludes links from the

count.

The widget displays the state of the device regardless of whether the state

of the device is confirmed or not (see “Acknowledge events” on page 92).

After each name in every field is an arrow. The arrow displays the trend

of the field since the last update. For example: the “Warning“ field in the

previous scan displayed 3, the current scan returns 2. The field displays

a down arrow in this case.

 Connection Summary Widget

The widget displays a summary of the connections contained in the entire

project. The summary displays connections according to the state of the

connection.

The widget displays the state of the connections regardless of whether

the state is confirmed or not (see “Acknowledge events” on page 92).

The arrow displays the trend of the field since the last update. For

example, the “Warning“ field in the previous scan displayed 3, the current

scan returns 2. In this case, the field displays a down arrow.

422

References

Tools > Dashboard

 Connection Status Widget

You can add multiple “Connection Status“ widgets to the dashboard. The

“Connection Status“ widget displays the link state and load of selectable

connections as graphs. The graphs display the load values and link state

in separate diagrams. The widget frame displays the color of the current

connection status. The widget retrieves the connection status from the

Industrial HiVision database. If Industrial HiVision detects an error on the

connection for any reason, then the widget frame displays the color

specified for a detected error.

Figure 107:“Connection Status“ widget with “Top to bottom“ function activated.

References

Tools > Dashboard

When you create a new widget, the widget is in the unconfigured state.

For example, you have not yet associated the widget with a connection

from a project. In this state the widget displays empty diagrams.

To configure the widget, use the following steps:

 Drag and drop the widget to a cell in the dashboard.

 To open the “Widget Parameters“ dialog, click the “Properties“ button

on the right side of the dashboard.

 Enter the desired history duration, in the “History Size“ field.

The “History Size“ range is from 1 min to 2 h. Default value is 30 min.

 Using the pull-down list, select the unit of measure.

 Assign a connection to the widget. In the “Connection“ field highlight a

connection.

 Click the “OK“ button.

Note: If you select an item that is not a connection, the widget displays

“Widget Configuration Error“.

The widget collects the “In Load“ and “Out Load“ data from the server and

displays it on a history graph. The history graph slowly scrolls across the

widget allowing you to read the information. The widget displays the graph

until you close the widget or specify a different connection.

The “Widget Parameters“ dialog also allows you to configure the visual

aspects of the widget. To configure the widget to display the lower “Out

Load“ diagram directly underneath the upper “In Load“ diagram, mark the

“Top to bottom“ checkbox. To change the load graph from a solid bar type

to a stacked bar type, mark the “Stacked“ checkbox. Each bar displays

the status of the data set according to the diagram type for example, solid

or stacked bars. The widget stores and displays the status configuration

of each data set.

Note: The solid bar diagram draws the bar using the color that represents

the status of the value at that time. The stacked bar diagram displays the

parts of the bar that are below, between or above the thresholds in a

different color. This makes it possible to display changes in the status

configuration.

The widget uses the same thresholds configured in the graphical user

interface. See “Properties of a connection” on page 290.

424

References

Tools > Dashboard

Figure 108:“Connection Status“ widget with “Top to bottom“ and “Stacked“ functions

activated.

The widget attempts to determine the load in both directions using various

means. The widget obtains the values from the database in the following

order:

 “In Load“ property values from both end ports of the connection. The

legend displays the direction of the traffic.

 If one side does not provide an “In Load“ property, then the widget

uses the “Out Load“ property of the opposite side. The legend displays

the direction of the traffic.

 If only one side of the connection is a port, then the widget uses the “In

Load“ and “Out Load“ of this port. The legend displays the name of the

end point with either “In Load“ or “Out Load“ appended.

 If the direction of traffic cannot be determined, the diagram and the

legend remains empty.

If you change the connection associated with a widget, then the widget

reflects the changes immediately. If you delete the connection, then the

widget displays “Widget Configuration Error“.

 Kernel Status Info Widget

The “Kernel Status Info“ widget displays information about the Industrial

HiVision kernel.

Additional information about the Industrial HiVision kernel is located in a

following chapter, See “Kernel Info” on page 449.

The widget displays the following information:

 “Kernel uptime“

The elapse time since Industrial HiVision was started.

 “Memory Usage“

The percent of memory that the services are using. Industrial HiVision

calculates the percent of memory as follows:

percent = actual memory used/reserved memory

 “Polling Operations per Minute“

The specified number of operations that the kernel can perform in a

minute.

 “Polling Operations last Minute“

The number of operations that the kernel was able to perform in the

last minute.

 “Polling Operations dropped“

The number of operations that the services dropped in the last minute.

You can influence the number of polling operations dropped by

changing the number of polling operations monitored or changing the

polling interval.

Note: For further information about configuring the parameters that the

kernel polls See “Monitor” on page 304.

 Security Summary Widget

The “Security Summary“ widget displays the security relevant

parameters.

The “Vulnerable Devices“ field displays the number of devices that are

vulnerable to attack. Vulnerable devices have at least 1 function enabled

that is recommended to be disabled, such as the http or SNMP v1/v2

protocols. The widget also counts devices which have the security

functions disabled. The number displayed in the widget represents the

number of devices in your project with a security status worse than OK.

The Industrial HiVision GUI “Security Status“ tab identifies which devices

the widget has included in the results and the security risks. To decrease

the number of devices in the count and increase network security, disable/

enable the functions identified in the “Security Status“ tab. You can also

use the MultiConfig™ “Security Lockdown“ function.

The “Rogue Devices“ field displays the number of devices in the rogue

device map See “Detecting rogue devices” on page 206. When the

number of rogue devices is more than 0, the widget displays the color that

you specified as „Warning“.

Note: The widget displays a warning triangle to the right of the “Rogue

Devices“ field. The triangle is to remind you to activate the function. The

widget hides the triangle after you activate the “Rogue Device Detection“

function.

The “Config. Signature Changes“ field displays the number of devices

with a configuration change. The field counts every change even when

the changes were returned to the original value.

In order for the widget to display the properties, specify a reference value

and configure status calculation as follows:

 Open the “Properties“ tab in the Industrial HiVision Graphical User

Interface (GUI).

 Open the “Property:“ drop down list, select “Configuration Signature“.

 Highlight the device or devices in the table without an active

“Configuration Signature“.

The devices with an active “Configuration Signature“ have a check

mark in the “Status“ column. You can filter the table to locate the

devices that require activation. To filter the table, click on the “Status“

column header until the table displays the entries at the top.

For further information about ICMP moving averages See “Service

Parameters” on page 388.

 Top 10 Moving Avg Response Time Widget

The widget displays the moving average response time of up to 10

devices. The devices with the higher moving average response time are

displayed at the top of the chart.

431

References

Tools > Dashboard

To configure the widget, open the “Widget Parameters“ dialog using the

“Properties“ button. The dialog allows you to specify which protocol the

widget displays. You can select from the following protocols using the

drop down list:

 Ping (default setting)

 SMNP V1

 SMNP V3

The widget displays a trend arrow next to the IP address of each device.

The trend arrow indicates the movement in position of a device, with

reference to the other devices displayed in the widget, since the last poll.

The information provided in the widget helps you to plan for optimal

performance in your network. For example, the widget displays which

device has a high average response time. A high average response time

can cause a bottle neck in your network. If a device with a high response

time is in the middle of your network, then the device can effect the other

devices in your network. Replacing the slow device allows the data

stream to be transmitted unhindered.

The following list contains some possible causes of high response times:

 Device is overwhelmed with data being sent to the CPU.

Receiving and forwarding data is the primary task of a network device.

Processing management requests are secondary tasks.

 The path to the device is slow.

- Slow connection

- Slow connection of neighbor

- Old fiber or Ethernet cable

Note: When you configure the widget for the first time, there is a

possibility that the widget displays high response times. In this case, allow

the display to stabilize before taking action. If after 1 minute the average

response time for a device remains high, then consider taking action.

432

 PoE Status

The “PoE Status“ widget allows you to monitor the status of the PoE

devices in your network.

The widget displays the sum of the warnings found in the “PoE“ tab for the

following parameters:

 “Class 0 Detected“

Displays the sum of the ports on which the device has detected that a

class 0 device is connected.

 “Device“

Displays the sum of the devices on which the “Device Limit“ is

exceeded.

 “Module“

Displays the sum of the modules on which the “Module Limit“ is

exceeded.

 “Port“

Displays the sum of the ports on which the “Port Limit“ is exceeded.

The arrow displays the trend of the field since the last update. For

example, the “Class 0 Detected“ field in the previous scan displayed 3, the

current scan returns 2. In this case, the field displays a down arrow.

If you disable the “PoE Class 0 Detection“ function on ports in the “PoE“

tab, then the widget displays a warning triangle next to the “Class 0

Detected“ field. Ports on which you disabled the detection function are not

included in the number entered in the “Class 0 Detected“ field.

Note: If the widget displays a warning triangle next to a field, then there

can be more items effected than the number indicates.

Note: Industrial HiVision allows you to use the graphical user interface of

Hirschmann products with the “Device Configuration“ function independent

of other applications, such as a browser or an installed Java environment.

Hirschmann has developed Industrial HiVision as an application that enables

you to use the graphical user interface easily with the “Device Configuration“

function in a closed network.

When Industrial HiVision sets up a secure connection with HTTP or SSH,

Industrial HiVision does not check the identity of the device with which

Industrial HiVision is connecting. Additionally, Industrial HiVision does not

display the identity of the device to the user. Someone attacking the network

could take advantage of this omission of a check to access sensitive

information.

Recommended actions use Industrial HiVision in a closed network. Do not

use the “Device Configuration“ function and MultiConfig™ dialogs that use

HTTPS in an open network. Perform an update of Industrial HiVision as soon

as a newer version is available.

8.13.4 CLI

The “CLI“ tool allows you to create a connection to the selected device from

the Industrial HiVision interface. Industrial HiVision opens its own window.

Industrial HiVision automatically checks whether the device allows an SSH

session or a Telnet session. Industrial HiVision preferably establishes an

SSH session.

Note: Under Linux, the “CLI“ tool requires that Telnet and SSH clients are

installed and that the environment variable PATH contains the name of the

directory in which the “xterm” program is installed.

437

References

Tools > Dashboard

8.13.5 SNMP Browser

The “SNMP Browser“ tool enables you to read and write the MIB of a

selected device. Industrial HiVision displays the MIB in a new window.

Note: The “SNMP Browser“ is a freely usable additional software. The

“SNMP Browser“ is not subject to the system test.

8.13.6 Ping

The “Ping“ tool enables you to send a Ping query to the devices selected in

the window. Industrial HiVision opens a separate Ping window.

Note: Under Linux, the “Ping“ tool requires that the environment variable

PATH contains the name of the directory in which the “xterm” program

is installed.

8.13.7 HiDiscovery Scan

The “HiDiscovery Scan“ lets you discover the devices in the network that

support the HiDiscovery V1 protocol, as long as these devices have the

HiDiscovery V1 v1 protocol activated.

438

References

Tools > Dashboard

Note: As far as HiDiscovery V1 is concerned, Industrial HiVision only

supports the HiDiscovery V1 v1 protocol.

 Example configuration

In this example you scan your network to discover devices which have the

HiDiscovery V1 protocol active.

 Open the Preferences > Advanced > Management Station dialog.

 Select the adapter connected to the network that you wish to scan from

the Network Card Management Station > Default Network Card

(HiDiscovery V1) drop-down list.

 To save the values in Industrial HiVision and close the dialog, click the

“OK“ button.

 To scan the network, click the “HiDiscovery Scan“ button.

8.13.8 Scan Network

The “Scan Network“ function enables you to detect every device within an IP

address range of the network specified see “[Basics ]” on page 322. To start

a search for new devices, select the “Scan Network“ option from the drop-

down list.

The “Scan Network“ tool has a toggle function. The toggle function starts and

8.13.9 Demo Network

The “Demo Network“ program supplied allows you to simulate a network on

your computer in order to familiarize yourself with Industrial HiVision without

being connected to a network.

 To start the simulation of the demo network, select Tools > Demo

Network.

In the default state, the device discovery is activated by a trap, and Industrial

HiVision detects the demo devices. Industrial HiVision displays the demo

devices in the “New Devices“ folder. Because the demo network functions

without a network connection, the demo network is simulated using the local

host interface with the IP address 127.0.0.1 and differentiates the devices

through the port numbers: 127.0.0.1:9003, 127.0.0.1:9004, 127.0.0.1:9005.

The simulation replicates the following management functions of the devices:

 Topology discovery based on LLDP

 Line interruptions

 Line interruption in the MRP

 Missing power unit

 Network load on device 9010

 Switch signal contact on/off

 Change device temperature

8.13.10Calculate Availability

Due to their physical properties, each component in the network has a limited

lifetime. The MTBF is the mean time between failures.

Repairs of the components also take a certain amount of time. The MTTR is

the mean time to repair.

Industrial HiVision calculates the availability of a path based on the MTBF

and MTTR values of the affected devices along that path.

Industrial HiVision also considers redundant paths here.

The type of a connected device affects the availability of the network. A

redundantly connected switch/router has a bigger effect on the availability of

the network than a redundantly connected terminal device.
