You can use LANmonitor to check the connection quality between stations in the LAN, WAN or WLAN. LANmonitor sends ping command from the computer on which it is installed to the remote site at regular intervals. The responses it receives are the basis for a compiled report.
To enter the parameters and display the results of the ping test, LANmonitor has a dedicated dialog.
Configuring ping
- Host name or IP address: The remote site which is to be queried by Ping is entered here. The following information can be entered for all of the different network devices (servers, clients, routers, printers, etc.) which can be reached via LAN, WAN or WLAN.
Note: If a device is selected when the Ping dialog is opened with Device > Ping or via the context menu in LANmonitor, then the IP address of this device is assumed to be the remote site.
- Minimum ping interval: The time interval between two consecutive pings in [ms].
Note: The interval between two pings cannot be less than the packet transmission time, i.e. before sending a ping, the previous ping must have been answered or the ping timeout must have expired.
- Ping timeout: The time waited for the response to a ping to arrive [ms]. If this time expires and no response was received then the ping is assumed to be lost.
- Data: The size of a ping packet [bytes]. A "ping" is an ICMP packet which is generally transmitted without any content, i.e. it is just a header. To increase the load of the packets used for testing a connection, a payload can be created artificially. The overall packet size then consists of an IP header (20 bytes), an ICMP header (8 bytes) and the payload.
Note: The packets will be fragmented if the payload of the ICMP packets exceeds the maximum IP packet size.
- Execution: Repeat mode for the ping command. You have the option to stop the ping transmission manually, after a certain period, or after a specified number of sent data packets.
- Period evaluation: The right-hand portion of the Ping dialog displays the results of the ping test. The first column shows the sum values over the entire test; the second column shows only the values collected over the evaluation period, i.e. the sum of the most recent packets. Unanswered pings are not included in the evaluation.
Note: The period evaluation considers only the pings sent during the defined period.
Statistics
The following information is displayed for evaluation:
- Test run time: The total run time [hr./ min./ sec.]
- Transmitted: Total number of pings sent
- Run time of the last ping [ms]
- Received until timeout: The number of pings answered in the timeout period
- Minimum runtime
- Maximum runtime
- Average
- Standard deviation from the mean run time
- Received after timeout: The number of pings answered after the timeout period
- Late packets as a proportion of the total number
- Minimum runtime
- Maximum runtime
- Average
- Lost
- Last error
