A good website monitoring service is going to do much more than simply send an alert when a clubpenguin down. The most effective services will breakdown the response time of a web request into important categories that will permit the system administrator or web developer to optimize the server or application to offer the best possible overall response time.
Listed below are 5 important components of response here we are at an HTTP request:
1.DNS Lookup Time: The time it takes to get the authoritative name server for that domain and for that server to eliminate the hostname provided and return the appropriate IP address. If this type of time is too long the DNS server should be optimized in order to provide a faster response.
2.Connect Time: The time has come required for the web server to answer an incoming (TCP) socket connection and request and to respond by establishing the connection. If this describes slow it usually indicates the operating-system is trying to answer more requests than it can handle.
3.SSL Handshake: For pages secured by SSL, the time has come required for both sides to negotiate the handshake process and set up the secure connection.
4.Time for you to First Byte (TTFB): The time has come it takes for your web server to respond with the first byte of content following the request is distributed. Slow times here more often than not mean the internet application is inefficient. Possible reasons include inadequate server resources, slow database queries as well as other inefficiencies related to application development.
5.Time to Last Byte (TTLB): This is the time needed to return every one of the content, following your request may be processed. If this describes taking a long time it usually shows that the Internet connection is simply too slow or is overloaded. Increasing bandwidth or acquiring dedicated bandwidth should resolve this problem.
It is extremely challenging to diagnose slow HTTP response times without all this information. With no important response data, administrators are left to guess about the location where the problem lies. Lots of time and money could be wasted trying to improve different pieces of the web application with the hope that something will work. It's possible to completely overhaul an online server and application only to discover the whole problem was really slow DNS responses; a challenge which exists on the different server altogether.
Use a website monitoring service that will a lot more than provide simple outage alerts. The very best services will break the response time into meaningful parts which will allow the administrator in order to identify and correct performance problems efficiently.
