HP SiteScope - Is there a way to see which DNS server that a Server goes through?

Dear Experts,

We are currently using SiteScope 11.22 installed on RHEL.

I am wondering if it is possible to see which DNS server that the Linux machine resolves to?

In the resolv.conf file, we have several IP addresses that I assume the Linux machine uses.

So basically it does a round robin starting with the first IP address to see if it can resolve through that particular DNS server.

But I want to see if the Linux machine is actually going to the 2nd IP address on the resolv.conf file if the first IP address is unable to resovle the DNS.

 

Any advice on this is very much appreciated.

Thanks,

Hi,

 

You can give it a try with the URM, configure a remote connection for that Linux server, then in the available counters go to: Network Interfaces, choose transmitBytes, select all the instances available for that server.

 

If the transmitBytes is in 0, then that IP is not in use.

ok thanks Gunnar.
I have implemented the monitor but am still not sure what DNS server the linux machine is using as the monitor only tells me how many bytes were transmitted.

In this case there are 2 instances eth0 and lo (local host), that's the way to identify which is the one is active

Ok thanks for the response.

But how do I know the IP of the DNS server?

So this is what I got when I implemented the monitor.

I guess the info is show in the dashboard according to the order the IP's are configured, but I'm not sure about that.

Re: HP SiteScope - Is there a way to see which DNS server that a Server goes through?

is there anyway that SiteScope maybe can do a nslookup or something that can tell you which DNS server the remote machine is using because I want to see which DNS server it is using when a DNS server goes down or something.
Also is there a way to provide a traceroute in the body of the email other than using a ping monitor?
Thanks,

Hi,

 

You can create a script that execute the nslookup  and then use the SiteScope script monitor to run it, SiS will show the ouptut of that script.
