If you run the site, you may encounter some downtime. Sometimes, the Web server may shut down. It would be a very good thing if we could get an email when the server went down. We can easily schedule a Linux job, which periodically checks the status of the website and sends emails when problems arise.

The methods are as follows:

Step 1: create a script file named "downtime_detector.sh".

You can create this file in your home directory. Copy the following text to the script file you created.

If curl-s "http://www.programcreek.com/2016/08/leetcode-russian-doll-envelopes-java/" | grep-Q" Russian Doll Envelopes "then # if the keyword is in the content echo" the website is working fine "else echo" Program Creek Error "| / usr/sbin/sendmail youremail@gmail.comfi

The script checks whether the target web page contains the string "Russian Doll Envelopes". If the page contains a string, the page will render correctly. If not, a message is sent to the e-mail address.

Step 2: install "sendmail" on the Linux machine.

Sendmail is a popular and reliable tool that can be easily set up to send e-mail under Linux.

Sudo apt-get install sendmail step 3: create a cronjob.

Enter "crontab-e" to edit the cronjob list.
