Let's audit the nagios checks we have in SCL1 for DNS. DNS runs on the admin servers in SCL1. 

admin1a.infra.scl1.mozilla.com
admin1b.infra.scl1.mozilla.com
Assignee: server-ops → afernandez
The individual admin nodes already had DNS checks in place, however the actual VIPs did not.

According to DNS records RelOps only has the following nameserver VIPs in SCL1;
ns-vip.build.scl1.mozilla.com (10.12.48.19)
ns-vip.infra.scl1.mozilla.com (10.12.75.11)

According to the DHCPD configuration all vlans are set to use one of the above VIPs for the nameservers (domain-name-servers) except vlan69.

For the time being I added a PING and DNS check for (r74708.):
ns-vip.build.scl1.mozilla.com
ns-vip.infra.scl1.mozilla.com

* All checks are green and also set to alert contact group "build".

I also added a PING check for admin1.scl1.mozilla.com from Infra's scl3 nagios node.

In terms of bug request, this is "Resolved/Fixed", however, will keep open as have 1-2 pending items. Those items being that we are not checking the same services that we check on infra's admin nodes;
DHCP updates
DHCPD Configuration
Puppet catalog compilation
Puppet freshness
SSH
Time Sync
crond procs
etc

Will probably open new bugs for the above.
