I came across a post on Mashable about an article on 10 Free Website Uptime Monitoring services, out of that I have analyzed and found 2 of them the best free solution out of all. One is UptimeRobot and another one is pingdom. Whether you have single website or multiple, if you want to check and monitor uptime of your website to verify the reliability of your web-server or hosting company then you should deploy up-time-monitoring service for your website/web-application. If you are running critical application than one should consider buying or using one for monitoring them.
Let me give you some idea about both the services:
UptimeRobot is completely free service for monitoring websites.
# of websites you can monitor per account: 50
Check Interval: 5 minute
Alert by: email, sms, rss, twitter
UptimeRobot looks at your site header’s status codes every five minutes and if the code comes back with a problem, does further checks. Then, if there are still issues, it lets you know about it pronto. According to about-us, they will try to keep this service free as long as possible.
pingdom is commercial monitoring service but it has a free sign-up with limited # of monitor. Basic free account let's you monitor 1 website. It comes with free iPhone application and monthly summary report as email.
# of websites you can monitor per account: 1
Check Interval: 1 minute
Alert by: E-mail, SMS (up to 20 per month), push alerts via iPhone app
I like that it allows you to select the time interval between 2 checks and the big deal is that at minimum you can select interval to 1-minute. The configuration is great and you can configure URL by HTTP/S or custom HTTP/S where you can set the PAYLOAD. We can choose between HTTP, TCP Port/Ping/DNS/UDP, SMTP/IMAP/POP3.
