How do I run diagnostic tools without root access?

[jason0]

Hello, 

I have splunk starting up with systemd, and running as user splunk.    I went to run the performance tasks on my indexers.  Each of them failed.  under triggered collectors, it reads the collector stack trace failed.

I logged into the system in question, and looked at the splunk_rapid_diag.log file.  

tools_collector ERROR 139880958523200 - Error occurred for collector tcpdump while running `/usr/sbin/tcpdump -i any -w /tmp/tmpbkxib485/tcpdump_All_All.pcap`
Process finished with code=1

how do I run diagnostic tools without root access?

I expect this would affect any collectors using strace as well.
