A useful website monitoring service can do much more than simply send a reminder when a mysynchrony down. The most effective services will breakdown the response duration of a web request into important categories that will allow the system administrator or web developer to optimize the server or application to supply the best possible overall response time.
Listed here are 5 key components of response here we are at an HTTP request:
1.DNS Lookup Time: Enough time it takes to find the authoritative name server for the domain and for that server to resolve the hostname provided and return the right IP address. If the time is simply too long the DNS server must be optimized to be able to provide a faster response.
2.Connect Time: It is now time required for the net server to reply to an incoming (TCP) socket connection and ask for and to respond by setting up the connection. If this is slow it often indicates the os is trying to answer more requests of computer can handle.
3.SSL Handshake: For pages secured by SSL, it is now time required for both sides to negotiate the handshake process and hang up up the secure connection.
4.Time for you to First Byte (TTFB): This is the time it takes for your web server to reply with the first byte of content after the request is sent. Slow times here typically mean the net application is inefficient. Possible reasons include inadequate server resources, slow database queries and other inefficiencies associated with application development.
5.Time to Last Byte (TTLB): It is now time needed to return all of the content, following the request may be processed. If this is taking a long time it usually indicates that the Internet connection is simply too slow or possibly overloaded. Increasing bandwidth or acquiring dedicated bandwidth should resolve this problem.
It is extremely hard to diagnose slow HTTP response times without this information. Without the important response data, administrators are left to guess about in which the problem lies. Lots of time and money can be wasted trying to improve different components of the web application with the hope that something will continue to work. It's possible to completely overhaul an internet server and application only to find the whole problem really was slow DNS responses; an issue which exists on a different server altogether.
Utilize a website monitoring service that does a lot more than provide simple outage alerts. The best services will break the response time into meaningful parts which will allow the administrator to diagnose and correct performance problems efficiently.
