The worst-case for every single system administrator is when some business-critical service fails, and you never learn about it. How many times you were pretty sure everything is okay 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 whenever you sent your last e-mail, however now it’s down, and nobody at the office can send or receive e-mails. You missed the minute when the server crashed and, what’s worst, you get this news from your colleagues. Obviously, it could be far better if right now someone notices an issue, you might report that you know about this and work on the clear answer right now.
Just how to detect problems?
Since early ages of computer networks, administrators used the ping utility to try the reachability of a number in the network. This utility can be obtained on virtually all platforms and enables testing hosts in the neighborhood network and in the Internet کاهش پینگ. Thus, the very first obvious step for almost any administrator willing to try if the server is alive would be to ping it. The ping utility sends an ICMP request to the goal host and waits because of its reply. If the reply isn’t received within the timeout, the utility reports that the host is unreachable. It means that either the host has crashed and cannot send an answer, or the network connection to it is broken, 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 can be launched in the monitoring mode when ping requests are sent to the host regularly, and you can see if the connection status changes. This process can be utilized to track the connection to 1 host, but if you have multiple hosts, you will need to continuously switch between console windows and risk missing the minute when one of many connections fails. The standard ping utility isn’t built to be used as a watchdog to track connections to 1 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 could work in the 24/7 mode sending regular pings and analyzing responses to detect host outages.
There are a few free ping monitors available today to be employed for personal and commercial needs, with EMCO Ping Monitor Free being one of the very most powerful freeware tools. This is a visual interface utility that reports a couple of parameters for every single monitored host, including the typical ping response time and the response time deviation, which allows you to evaluate the connection quality.
In case of several ping failures to a number in a row, the utility reports an outage, meaning the connection to the host is lost. In this case, it can notify you by playing a sound, displaying an email in the tray, and sending an e-mail. You are able to configure most of the options depending on your needs. If you need to execute any custom action when the connection to a number is lost or restored, you are able to 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 up to five hosts, download a totally free Ping Monitor tool from EMCO. A commercial version can be available. It doesn’t have limitation of the amount of tracked hosts and includes an extended group of features.
