What is the difference between and in Splunk *nix Add-On?

Hi everyone,

I was wondering if anyone could tell me the main difference between these sourcetypes. As far as I can see in the scripts, they're both collecting network interface data, however while relies heavily on the ifconfig module which is broadly available among different Linux distributions, the bandwidth script uses the sar module, or as a substitution netstat on Solaris machines for example.

However looking at it from the official part, it seems that the interfaces sourcetype (indexed by isn't even used in Splunk's CIM, while the bandwidth sourcetype (for which I couldn't even find any trace in the official Add-On documentation) is used as main network activity source.

So getting back to my question, both commands list information about a systems network communication. Where is their big difference and which one should I use in which cases?

My two cents; - Shows stats per link-level Ethernet interface (simply, NIC)
Runs an eval ifconfig command and gets mac address, ipv4/6 addres, collisions, RXbytes, Rxerrors, Txbytes, Txerrors, speed and duplex settings. shows Network Utilization, Total Network, cpu statistics
Runs the sar -n command and gets the rxPackets_PS txPackets_PS rxKB_PS txKB_PS

I believe that the Nix app mostly uses the interfaces sourcetype and not so much the bandwoth sourcetype.

Best thing you can do is enable it on a test system and research both sourcetypes:
sourcetype=interfaces or sourcetype=bandwith explanation is missing from splunkdocs, or I cannot find it.
