DNS Monitoring service?
I have a client who decided it was better to handle their own DNS for their website. Now there have a been a few DNS outages and of course I am blamed as nobody could get to the site. I already have a monitor service for the site but when DNS is down it does not report that it is DNS over a site outage. Can anyone recommend a low cost service that will monitor DNS? I need something that gives a report to show that it is DNS, how many tries and how long it is out.
Thank you,
-G

DNS runs at port 53. Almost any monitoring system allows monitoring services. Add the NS and the port and you're done.
Pingdom supports DNS checks. You can get a free account which includes one check.
@Traffic Good idea, it would at least show it is out. But one of the outages was the person deleted the www record. The ping would still show alive. But I like the idea as I could monitor from more than one way.
@kcaj Thank you, I was thinking Pingdom was paid only and was more than I wanted to spend.
We've got good DNS monitoring.
@MisterG you'll need to get to the root of your issue. monitoring will just tell you it's down but doesn't rectify your problem
I think he wants to prove to his client that the issue isn't his service but the problem is the clients DNS servers.
@matthewvz as a matter of fact, you're quite right
I can confirm, pingdom is great to monitor DNS, definitely recommend
I'm using nagios
Thank you to everyone for your feedback. I am going to use pingdom to monitor the actual lookup and another provider just to monitor port 53. I figure I will have two different ways will help. Thanks again!
Cron is cheap...
#!/bin/bash DOMAIN="example.com" RESULT=$(/usr/bin/dig +time=5 +tries=2 +short $DOMAIN) if [ -z "$RESULT" ]; then echo "$DOMAIN lookup failed" fi exit 0Thanks @sleddog but I want (need) a third party to be able to show my client. You know how some people can be with proof. But I will keep this in mind for myself.
+1 for pingdom, you have a small fee but it is worth it and they have a neat app to go with it
I have been very happy with monitive.com
