I've installed the Splunk Add-on for Infoblox to the search head, index, and universal forwarder in one of our environments. Just playing around with the data it provides I decided to look at the built-in panels. One is a simple search for the top 10 source IPs over the last 24 hours:
index=test sourcetype="infoblox:dns" earliest=-1d client |top 10 src_ip|table src_ip count |rename src_ip AS "Client IP" count AS "Requests"
Problem is that "srcip" isn't a field in the data. It seems that it should be replaced with "dnsrequestclientip". We're not using Infoblox for DHCP but I see that this add-on does have a transform, I believe, for that sourcetype, infoblox:dhcp...just never makes it to infoblox:dns?
I believe this add-on may eventually tie into an implementation of the security app - I don't want change it much for that reason, and I'm thinking the built-in panel should work?
In this add-on, the events which contains text 'dhcpd' are included in sourcetype 'infoblox:dhcp', while the events contains 'named' are treated as 'infoblox:dns'. In our sample data, field 'src_ip' is extracted from the events.
To further dig into your question, could you provide some sample data?
We're seeing events where "client" has IPV6 address not getting extracted. For example, the following does not get extracted correctly -- while events with IPV4 addresses are getting extracted correctly:
2019-07-31T16:00:15+00:00 dns1.illinois.edu named: client 2001:558:fe04:a:69:252:244:142#53661 (xxxx.ad.uillinois.edu): query 'xxxx.ad.uillinois.edu/A/IN' denied
I see some add-ons have specifically addressed IPV6:
Does Infoblox add-on need this done too?
