The worst-case for each and every system administrator is when some business-critical service fails, and that you do not know about it. How many times you’re pretty sure that 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 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 the minute when the server crashed and, what’s worst, you receive this news from your own colleagues. Of course, it could be far better if right now someone notices a challenge, you can report that you already know just about any of it and will work on the perfect solution is 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 any administrator willing to check if the server is alive is to ping it. The ping utility sends an ICMP request to the goal host and waits for its reply. If the reply is not received within the timeout, the utility reports that the host is unreachable. It indicates that either the host has crashed and cannot send a reply, or the network connection to it is broken, and so the host cannot serve remote requests.
The ping utility can be utilized for one-time checking of the bond to the host so that 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 will see if the bond status changes. This method can be utilized to track the bond to at least one host, but if you have multiple hosts, you need to continuously switch between console windows and risk missing the minute when among the connections fails. The typical ping utility isn’t built to be properly used as a watchdog to track connections to at least one or multiple hosts, but if you need this feature, you need to use so-called network monitoring or ping monitoring tools.
Using ping monitor to track multiple hosts status
Ping monitoring tools can assist you to track the status of multiple hosts and be notified concerning the hosts’ups and downs کاهش پینگ. Ping monitors can work in the 24/7 mode sending regular pings and analyzing responses to detect host outages.
There are certainly a few free ping monitors available today to be useful for personal and commercial needs, with EMCO Ping Monitor Free being one of the very most powerful freeware tools. This can be a visual interface utility that reports a couple of parameters for each and every monitored host, including the common ping response time and the response time deviation, which lets you evaluate the bond quality.
In the event of several ping failures to a number in a row, the utility reports an outage, meaning the bond 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 most of the options depending on your own needs. If you need to execute any custom action when the bond to a number is lost or restored, you can register special handlers in the utility. You might configure the command, application or script file to be executed automatically when the bond 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 is also available. It doesn’t have limitation of how many tracked hosts and includes a long pair of features.
