You may see an error in your agent log accompanied by a triggered "no data received" alert.
This article is for our v1 agent and will soon be deprecated.
doPostBack: URLError = <urlopen error (-3, 'Temporary failure in name resolution')>
This happens if the agent is unable to resolve the serverdensity.com address for your account. Usually this means there is a problem with the nameserver resolvers you have configured for your server in /etc/resolv.conf. They may be unavailable or there may be a networking issue preventing connectivity to them.
This will resolve itself after a period of time but indicates a possible deeper problem which you may wish to contact your nameserver resolver provider about (often your web hosting company).
