By definition, an "uptime monitor" is a server service that regularly connects to one or more servers and verifies whether they are active and available. The uptime server should regularly ping the monitored server and if it fails to do so for a certain amount of time, then we can say the monitored sever is not working as expected.
Before we start talking about the monitors, we'll see what "uptime" is. "Uptime" (Up Time) means the time elapsed since a system started running until it crashes. If you don't want your server or service to crash and prefer to use it for at least 24 hours; then we should take some precautions. We can't prevent a crash, but we can find out the reasons for a crash and resolve these problems.
Uptime monitors are used to keep track of whether an app or service is up or down. It works by regularly pinging the host/service, and if it doesn't get any response, you will get an alert notifying that your server is down.
The most common cause for downtime in modern servers is power supply failure. Other issues like earthquakes, fires, floods, building constructions are the other examples for the same. It might be because of a virus or software bug too. When your server stops working due to an error, you should try to "reboot" it (restart it). If you restart your server at least once in 6 months, then it is good for its "uptime".
If you want to check the uptime of your server right now, just type "uptime" in Linux terminal. It will display the time elapsed since the last boot process in hours and minutes. If you need more information about this command, just type "man uptime".
Uptime Monitors enable administrators to address issues like system outages before they become problems that affect business functions and operations. When the services on a server go down, uptime monitors notify administrators so they can act quickly to resolve the issue before it becomes a problem that affects business functions.
The types of alerts that uptime monitors can generate are:
Alerts are messages that inform administrators about critical conditions regarding system availability.
- Notifications about specific services going down or coming up.
- Alerts when certain applications or processes have been stopped or started.
- Alerts when the number of logged users has reached a certain threshold.
- Sends notifications via email, SMS or instant messenger when a server goes down.
Some common features of uptime monitors are the following:
- Flexible scheduled monitoring enables users to monitor predefined intervals.
- Provides quick access to current availability status of all monitored servers and services.
- Offers centralized configuration and management of monitored servers and services with a user-friendly web interface.
- Provides detailed reports about all current issues through historical views.
If you are tired of spending countless hours troubleshooting problems with your servers, uptime monitor might be the answer you are looking for. If you can't afford to lose business because of system outages, then uptime monitoring is something that you should use today.
