What is the example of basic network monitoring?

Answered by Willie Powers

Basic network monitoring is a crucial aspect of maintaining the health and performance of a network. It involves monitoring the availability and reachability of network hosts, and one popular tool used for this purpose is ping. Ping is a simple yet powerful command-line tool that is available in most operating systems, including Windows, macOS, and Linux.

Ping works by sending Internet Control Message Protocol (ICMP) echo request packets to a specific host or IP address and waiting for an ICMP echo reply. The tool measures the round-trip time it takes for the packets to reach the destination and return to the sender.

Let me provide you with an example to illustrate how ping works. Suppose you want to test the availability of a web server with the IP address You can open a command prompt or terminal window and type the following command:


After hitting the enter key, ping sends several ICMP echo request packets to the specified IP address. If the host is active and reachable, it will respond with ICMP echo replies, indicating that it is online and accessible. Ping then displays the round-trip time for each packet, giving you an idea of the network latency.

For example, the output of the ping command may look something like this:

Pinging with 32 bytes of data:
Reply from bytes=32 time=2ms TTL=64
Reply from bytes=32 time=3ms TTL=64
Reply from bytes=32 time=2ms TTL=64
Reply from bytes=32 time=2ms TTL=64

Ping statistics for
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milliseconds:
Minimum = 2ms, Maximum = 3ms, Average = 2ms

From the output, you can see that all four ICMP echo requests were successfully received by the host at, with no packet loss. The round-trip times indicate that the network latency is relatively low, ranging from 2ms to 3ms.

Ping is not only useful for testing host availability but also for diagnosing network issues. If a host does not respond to ICMP echo requests, it could indicate a network problem or that the host is offline. Additionally, if you observe high packet loss or significant variations in round-trip times, it may indicate network congestion or performance issues.

Ping is a fundamental network monitoring tool that allows you to test the availability and reachability of network hosts, as well as measure packet loss and network latency. By using ping, you can gain insights into the health and performance of your network and troubleshoot potential issues.
