Importing Michael Shield's script for gathering diagnostic data
on active Helix server processes running on Linux servers.
The script tails the log and journal, runs lsof, netstat and ps,
and gathers strace output on active p4d processes. Additionally,
the script tails /var/log/messages and runs 'p4 monitor'.
Adding as text+x (not text+kx) to preserve change and date keywords
