Exactly how to be able to Reduce Server Outages.

The worst-case for every system administrator is when some business-critical service fails, and that you do not learn about it. How many times you were 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 had been 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 once the server crashed and, what’s worst, you get this news from your own colleagues. Of course, it will be definitely better if at the moment someone notices a challenge, you might report that you know about it and are working on the clear answer right now.

How to detect problems?
Since early ages of computer networks, administrators purchased the ping utility to check the reachability of a bunch in the network. This utility is available on virtually all platforms and enables testing hosts in the local network and in the Internet. Thus, the initial 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 the reply. If the reply isn’t received within the timeout, the utility reports that the host is unreachable. This means that either the host has crashed and cannot send an answer, or the network link with it’s broken, 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 may be launched in the monitoring mode when ping requests are provided for the host regularly, and you will see if the bond status changes کاهش پینگ. This method can be utilized to track the bond to 1 host, but if you have multiple hosts, you need to continuously switch between console windows and risk missing as soon as when one of many connections fails. The standard ping utility isn’t designed to be used as a watchdog to track connections to 1 or multiple hosts, but if you need this feature, you should use so-called network monitoring or ping monitoring tools.

Using ping monitor to track multiple hosts status
Ping monitoring tools can help you track the status of multiple hosts and be notified concerning 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 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 most powerful freeware tools. This can be a visual interface utility that reports a couple of parameters for every monitored host, including the common ping response time and the response time deviation, which allows you to evaluate the bond quality.

In the event of several ping failures to a bunch in a line, 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 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 bond to a bunch 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 bond to a bunch is lost or restored.

To track link with up to five hosts, download a free Ping Monitor tool from EMCO. A professional version can also be available. It doesn’t have limitation of the number of tracked hosts and includes a long set of features.
