Access Monitoring Tools
For supported software information, click here.
You can monitor the network using the ping, tcpdump, and traceroute commands, and you can run a speed test.
To access tools to monitor devices in the network:
- In Director view:
- Select the Administration tab in the top menu bar.
- Select Appliances in the left menu bar.
- Select an appliance in the main panel. The view changes to Appliance view.
- Select the Monitor tab in the top menu bar.
- Select an organization in the submenu bar. The following screen displays.
- Select the Tools tab to access the following tools:
- Ping
- Traceroute
- Tcpdump
- Speed Test
Ping
Ping is a networking tool that tests the reachability of a device on a network by sending out a special message, called an "ICMP echo request", and measuring the time it takes to receive a response.
- Click Run Ping, and then enter information for the following fields.
Field Description Host Name/Address Enter the host name or IP address of the host that will receive the ping packets. Routing Instance Select a routing instance to use to send the ping packets. Source Address Enter the IP address from which the ping packets are sent. Packet-size Enter the number of data bytes to be sent in the ping requests. Count Enter the number of packets to send before stopping ping requests. If you do not specify the count, ping will continue to send packets until interrupted.
Range: 1 through 10Default: 10
- Click Start. The results display under Latest Results.
Traceroute
Traceroute is a diagnotic tool that maps the path taken from a source device to a destination device. It can help identify the cause of network outages and other issues.
To trace a route:
- Click Traceroute, and then enter information for the following fields.
Field Description Target Host Name/Address Enter the host name or IP address of the target host. Routing Instance Select a routing instance to use to send the traceroute. Source IP Enter the IP address from which the traceroute is sent. Packet-size Enter the number of data bytes to be sent in the traceroute. Protocol Select the protocol to use for the traceroute, either ICMP ECHO or TCP SYN. - Click Start. The results display under Latest Results.
Tcpdump
Tcpdump is a command-line tool that captures and analyzes network traffic. You can use tcpdump to identify network issues and malicious activity. In addition to viewing real-time results, you can save the output to a local file for later analysis. The -c option captures x number of packets and then stops. If you do not use this option, tcpdump runs indefinitely.
To run tcpdump on an interface:
- Click Tcpdump, and then enter information for the following fields.
Field Description Interface Select the interface for tcpdump to use to capture and analyze the network traffic. Timeout (sec) Enter the amount of time, in seconds, before the tcpdump times out. Filter Enter the type of filter to be applied using the standard tcpdump command syntax. By default, the -c 100 filter is used, which tells tcpdump the maximum number of packets (packet count) to capture before terminating. Number of Packets Enter the number of packets to be captured before tcpdump terminates. - Click Start. The following screen displays.
- You can click the Stop button to end tcpdump, or you can wait until the tcpdump finishes.
- Once tcpdump finishes, the following screen displays.
- You can click Download to download a file with the tcpdump output to your local system.
Speed Test
You can run a speed test using a Versa Operating System™ (VOS™) device as a speed-test server, or by using an internet speed-test server.
If you use a VOS device as a speed-test server, you can then initiate the speed test from a local VOS device to test the link between the VOS device and the VOS speed-test server. For information about setting up a VOS device to be a speed-test server, see Troubleshoot Link Bandwidth Issues.
Note: Before you can run a speed test using a VOS device as the speed-test server, you must configure the VOS device to be a speed-test server. See Troubleshoot Link Bandwidth Issues for more information.
If you use an internet speed-test server, you run the speed test from a VOS device to a predeployed internet speed-test server. For information, see Run Internet Speed Tests.
To run a speed test using a VOS device as a speed-test server:
- Click Speed Test, and then enter information for the following fields.
Field Description Remote IP Address/FQDN Enter the IP address or fully qualified domain name of the remote device. Network Select a network to use for the speed test from the drop-down list. - Click Test Speed.
To run a speed test using an internet speed-test server:
- Click Speed Test, and then click the Internet tab. The following screen displays.
- In the Routing Instance field, select the routing instance to use to run the speed test.
- To run the speed test using the default internet speed-test server, click Test Speed.
- To select a specific internet server to use for the speed test:
- Click Advanced Settings. The following screen displays.
- Select the routing instance to use for the speed test.
- Click Fetch Server List. The screen displays a list of speed-test servers and their Server ID numbers.
- Choose one of the servers, and then enter the server's ID number in the Server ID field.
- Click Test Speed to initiate the speed test using the specified internet speed-test server.
- Click Advanced Settings. The following screen displays.
