Troubleshooting

• When starting the Visualizer Server, the error message ‘network service could not be opened. Please check settings’ was displayed, and it could not start.
• When starting the Visualizer server, the error message ‘unable to start server (Service: Syslog receiver causes SocketException: Address already in use)’ was displayed and it could not start.
• On a UNIX machine, when carrying out ‘./VisualizerServer.sh’, ‘Visualizer Server started…’ is displayed but it does not return to command prompt.
• On a Windows machine, the Visualizer server was started, and a client installed on a separate machine could use it normally, but after log out the connection was abruptly broken and it could not be used. Both machines have been restarted but they aren’t recovering.
• On the network map generation function, there is a device which is not detected.
• After automatically generating a network map, the SNMP reachability monitoring was activated, but many hosts respond as ‘unreachable’. SNMP reachability is being checked manually from the automatic map generator.
• When generating a network map for a network with several tens of network nodes, the process was slow and stopped midway through the probe.
• The label change process is listed in 3.3.1 of the user manual, but ‘label change’ is not listed in the drop-down menu after right clicking an element on the network map.
• How can a network map be generated by Designer with its nodes color coded to reflect the reachability monitoring target status?
• Events displayed in the event console were hidden after setting the ‘display type selection’ and ‘data type selection’. Even after changing the display type to ‘default’ and ‘display all’ they remain hidden.
• After screening CpMonitor with the user status/order function (real-time), an item called Delta was displayed for each interface, but other information could not be displayed.
• I want user status (records) to be displayed but even though I clicked on one that should have information it displayed an error saying ‘the data you wanted could not be found’.

Troubleshooting

When starting the Visualizer Server, the error message ‘network service could not be opened. Please check settings’ was displayed, and it could not start.

When starting the Visualizer Server, the error message ‘unable to start server (Service: Syslog receiver causes SocketException: Address already in use)’ was displayed and it could not start.

1. Change the port number used by the syslog receiver service(Please Refer to Section 13.1.3 ‘Syslog Receiver.conf’, NetSkate Visualizer Pro Reference Manual)


2. Don’t start the syslog receiver service
   
   Set the following options in the startup script
   
   
   
   • -Dcom.cysols.service.syslog.module.server.SyslogReceiverService=false
   
   

#!/bin/sh
jre/bin/java \
-Dcom.cysols.service.syslog.module.server.SyslogReceiverService=false \
-Djava.awt.headless=true -cp \
"visualizer_server.jar:lib/mail.jar:lib/activation.jar:plugin/pro_server_plugin.jar" \
com.cysols.visualizer.server.VisualizerServer

On a UNIX machine, when carrying out ‘./VisualizerServer.sh’, ‘Visualizer Server started…’ was displayed but is not returned to command prompt.

# ./VisualizerServer.sh &

On a Windows machine, the Visualizer server was started, and a client installed on a separate machine could use it normally, but after log-out the connection was abruptly broken and it could not be used. Both machines were restarted but they did not recover.

On the network map generation function, there is a device which is not detected.

After automatically generating a network map, the SNMP reachability monitoring was activated, but many hosts respond as ‘unreachable’. SNMP reachability is being checked manually from the automatic map generator.

When generating a network map for a network with a few tens of network nodes, the process was slow and stopped midway through the probe.

The label change process is given in 3.3.1 of the user manual, but ‘label change’ is not listed in the drop down menu after right clicking a network map element.

How can a network map be generated by Designer with its nodes color coded to reflect the reachability monitoring target status?

1. Set the correct IP address and subnet mask of the appropriate PC node while editing the map


2. 2. Set the Ping reachability monitoring corresponding to the set IP address

Events displayed in the event console were hidden after setting ‘display type selection’ and ‘data type selection’. Even after changing display type to ‘default’ and ‘display all’ they remain hidden.

After screening CpMonitor with the user status/order function (real-time), an item called Delta was displayed for each interface, but other information could not be displayed.
