Best Free Website Uptime Monitor
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. See URL configuration screen below:
I would say it's worth trying and buying if one is running with critical business application over the Internet.
Another winning point pingdom has is that monitor checks uptime from the server's located all over the web and it give you idea about response time from many locations in the word. (I saw that every minute check was from different location/server, ranging from various states in the United States to UK and many other countries.)
While UptimeRobot has deployed 2 server's when URL is reported as failed from one server they will have it verified on another and will be reported as failed only if it fails on both the server.
To be on safe side 4 weeks back I have deployed both pingdom and UptimeRobot for one of the critical web-application and when I saw monthly report 100% uptime, it was happy moment for me to see that.
How is your experience with website uptime monitoring system, you might have tried so far?
I would say if you're running with critical business application which you can't afford to have down for a minute than go pick pingdom, but if you're enthusiast who wan't monitor websites to make sure they are almost up try UptimeRobot or deploy both.! 🙂
