Use an ICMP Ping check with ActiveXperts Network Monitor
ActiveXperts Network Monitor is a software solution you need to scan your network servers, workstations and devices for failures or irregularities. With ActiveXperts Network Monitor, you can identify issues and fix unexpected problems before your others even know they've happened.ActiveXperts Network Monitor maximizes network availability by monitoring all aspects of your servers, workstations, switches, routers, printers and any other devices. It can also detect temperature, humidity and other environmental aspects in your server rooms.
Once a computer has obtained an IP address and a subnet mask, you should test the IP communications. Ping is the utility that can be used for verifying IP-level connectivity. Ping sends the ICMP echo request to the destination host and analyzes ICMP echo replies.
Use ActiveXperts Network Monitor's ICMP Ping checks a remote host for availability. Local hosts should normally respond to ping requests within milliseconds. However, on a very congested network it may take up to 3 seconds or longer to receive an echo packet from the remote host. If the timeout is set too low under these conditions, it will appear that the remote host is not reachable (which is almost the truth). ActiveXperts Network Monitor checks servers for availability by sending ICMP Echo commands and wait for the responds. An ICMP timeout failure doesn't necessarily mean that the remote host is actually functioning beyond its ability to echo packets.
An ICMP/Ping check has the following parameters:
- Host - The DNS name or IP address of the computer you want to ping (can even be a WINS name, but only if the name can be resolved by some WINS server in the network);
- Timeout for each reply - Maximum number of milliseconds it may take before a response is received;
- Number of echo requests - Number of echo requests to send;
- Time to Live - Maximum Time to Live (TTL) value;
- Buffer size - Send buffer size.
