A good website monitoring service will do much more than simply send an alert when a abs-cbnnews.com. The very best services will break down the response period of a web request into important categories that will permit the system administrator or web developer to optimize the server or application to provide 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: Time it takes to find the authoritative name server for your domain as well as for that server to eliminate the hostname provided and return the right IP address. If this time is simply too long the DNS server must be optimized to be able to provide a faster response.
2.Connect Time: This is the time required for the net server to respond to an incoming (TCP) socket connection and ask for and to respond by creating the connection. If this is slow it always indicates the os is trying to reply to more requests of computer can handle.
3.SSL Handshake: For pages secured by SSL, the time has come required for either side to negotiate the handshake process and hang up up the secure connection.
4.Time to First Byte (TTFB): The time has come it takes for your web server to react with the first byte of content following your request is shipped. Slow times here more often than not mean the web application is inefficient. Possible reasons include inadequate server resources, slow database queries as well as other inefficiencies related to application development.
5.Time and energy to Last Byte (TTLB): This is the time needed to return every one of the content, after the request has been processed. If this sounds like taking a long time it usually suggests that the Internet connection is too slow or perhaps is overloaded. Increasing bandwidth or acquiring dedicated bandwidth should resolve this challenge.
It is extremely difficult to diagnose slow HTTP response times without all of this information. With no important response data, administrators are still to guess about in which the problem lies. Lots of time and money can be wasted attempting to improve different components of the web application with the hope that something will continue to work. It's possible to completely overhaul a web server and application only to find out the whole problem was really slow DNS responses; a problem 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 which will allow the administrator to identify and correct performance problems efficiently.
