You can get similar results using curl:

 X=`curl -s -S -L -w '%{time_total}' -o /dev/null http://www.yahoo.com`

$X will be set to the total time taken to download the webpage. Obviously the output can be directed to an actual file instead of /dev/null. Curl can also handle cookies and form posts, as well as simple page fetches. I've used it very effectively to login to a variety of sites and navigate to a certain point to check availability of pages.

Note that neither Lynx nor curl will be downloading images, javascript, java apps, etc, which will tend to skew your graphs somewhat.

I wrote a script which uses the text based Lynx web browser and the Linux time command to check how on it takes a web app to respond to downloading the initial page. I set up a custom graph to graph the results and we can now trend when web response is slower on our network. Below is the script. I had to add a space between h and ttp in the lynx command line so my mail client wouldn’t try to make it a link.

Hi All,

Can XYMON having feature to check "User Experience".

We are having different web based application, running in LINUX/Solaris server.

Some time We observed all applications are showing running state but if we click any icon(inside our own application) the response time is too long/some-time not get the result also.

Kindly let me know any feature is available in XYMON to track it out.

With Thanks & Regards,

Jayanta.
