The worst-case for each and every system administrator is when some business-critical service fails, and that you do not learn about it. How often you had been pretty certain that everything is fine with the infrastructure until someone from the management called you and reported that the corporate mail server (or you name it what) is down? Yes, right, it absolutely was OK ten minutes ago when you sent your last e-mail, however now it’s down, and nobody at the office can send or receive e-mails. You missed as soon as when the server crashed and, what’s worst, you obtain this news from your colleagues. Of course, it could be definitely better if right now someone notices an issue, you could report that you already know just about any of it and will work on the clear answer right now.
Just how to detect problems?
Since early ages of computer networks, administrators purchased the ping utility to check the reachability of a number in the network. This utility is available on nearly all platforms and enables testing hosts in the local network and in the Internet. Thus, the first obvious step for just about any administrator willing to check if the server is alive would be to ping it. The ping utility sends an ICMP request to the target host and waits for the reply. If the reply is not received within the timeout, the utility reports that the host is unreachable. This means that either the host has crashed and cannot send a reply, or the network connection to it’s broken, and so the host cannot serve remote requests.
The ping utility can be utilized for one-time checking of the connection to the host so you could simply know if the host is up or down. Also, it may be launched in the monitoring mode when ping requests are delivered to the host regularly, and you can see if the connection status changes. This method can be utilized to track the connection to at least one host, but when you yourself have multiple hosts, you will need to continuously switch between console windows and risk missing as soon as when one of many connections fails کاهش پینگ. The standard ping utility isn’t built to be utilized as a watchdog to track connections to at least one or multiple hosts, but if you need this feature, you can use so-called network monitoring or ping monitoring tools.
Using ping monitor to track multiple hosts status
Ping monitoring tools can allow you to track the status of multiple hosts and be notified in regards to the hosts’ups and downs. Ping monitors can work in the 24/7 mode sending regular pings and analyzing responses to detect host outages.
There are always a few free ping monitors available today to be used for personal and commercial needs, with EMCO Ping Monitor Free being one of the very powerful freeware tools. This is a visual interface utility that reports some parameters for each and every monitored host, including the common ping response time and the response time deviation, which allows you to evaluate the connection quality.
In the event of several ping failures to a number in a line, the utility reports an outage, which means that the connection to the host is lost. In this instance, it may notify you by playing an audio, displaying a note in the tray, and sending an e-mail. You are able to configure all of the options depending on your needs. If you want to execute any custom action when the connection to a number is lost or restored, you can register special handlers in the utility. You could configure the command, application or script file to be executed automatically when the connection to a number is lost or restored.
To track connection to around five hosts, download a totally free Ping Monitor tool from EMCO. A commercial version can be available. It doesn’t have limitation of the number of tracked hosts and includes a long group of features.
