A good website monitoring service will do much more than simply send an alert when a shopgoodwill down. The best services will break down the response period of a web request into important categories that will enable the system administrator or webmaster to optimize the server or application to supply the best possible overall response time.
Here are 5 key components of response here we are at an HTTP request:
1.DNS Lookup Time: Time it takes to find the authoritative name server for your domain as well as for that server to resolve the hostname provided and return the correct IP address. If this type of time is too long the DNS server must be optimized so that you can provide a faster response.
2.Connect Time: It is now time required for the net server to respond to an incoming (TCP) socket connection and ask for and to respond by establishing the connection. If this describes slow it always indicates the operating system is trying to answer more requests than it can handle.
3.SSL Handshake: For pages secured by SSL, this is the time required for either side to negotiate the handshake process and set up the secure connection.
4.Time and energy to First Byte (TTFB): This is the time it takes for your web server to reply with the first byte of content following your request is shipped. Slow times here almost always mean the net application is inefficient. Possible reasons include inadequate server resources, slow database queries and other inefficiencies related to application development.
5.Time and energy to Last Byte (TTLB): This is the time needed to return all the content, following your request has been processed. If this describes taking too long it usually indicates that the Internet connection is just too slow or perhaps is overloaded. Increasing bandwidth or acquiring dedicated bandwidth should resolve this issue.
It is extremely hard to diagnose slow HTTP response times without this information. Without the important response data, administrators remain to guess about the location where the problem lies. A lot of time and money can be wasted attempting to improve different pieces of the web application with the aspiration that something will work. It's possible to completely overhaul an internet server and application only to discover the whole problem was actually slow DNS responses; a challenge which exists on the different server altogether.
Make use of a website monitoring service that will a lot more than provide simple outage alerts. The most effective services will break the response time into meaningful parts that will allow the administrator to identify and correct performance problems efficiently.
