Saivaneri Web Tutor CHAPTER 8 Okay guys, I think now you will pretty much have become a web master already!. Now you are hosting it on www.yoursite.com, you have your own email id like www.yourlovelyname@yaourname.com and boasting to every one about your prowess!. But many of your friends return to say that they went to your site, which said “505 DNS Error!” GOOFED?. Oh there are many more thing to monitor now, because your web site is a 24 hour/7 days a week/365 days a year growing child, which needs constant nourishing, monitoring. To resolve any web site, you need an IP Number and a DNS server. As already we have seen, DNS server maintains a table of www.yourname.com and resolves to the particular IP number. But suppose DNS server has become blind to your IP Number what you get? You get this 505 error!. So you should always monitor that your DNS entry is correct. This can be done by registering yourself at www.internetseer.com or www.webstat.com etc. This site also will spider your site every day at a particular interval say every hour, so that it checks to see that your DNS, web site, web server, name sever, back bone, gate way are all alive. What a welcome relief!. We want the World to be automated like this isn’t it?. Internetseer also reports you alerts if any of the above is down. This is called UPTIME MONITORING!. 60% of the Worlds’ best sites are hosted on *NIX variants, so the UPTIME for them is really good. Not to say about WIN* products, because we see their performance at your desktop (pulling a month is itself difficult!) There are FREE and PAID services at these monitoring sites. Ofcourse there are differences in services also. Decide as per your sites’ potential. What all you can monitor?
