+==== Process Uptime ====
+Find the process ID of the master (parent process), then:
+<sxh bash>
+ls -ld /proc/3380
+</sxh>
+Output looks like:
+<sxh bash>
+dr-xr-xr-x 8 root root 0 Nov 12 23:05 /proc/3380
+</sxh>
+or
+<sxh bash>
+ps -eo user,pid,cmd,etime,ppid | grep http
+</sxh>
+<sxh bash>
+ps -eo user,pid,cmd,etime,ppid | grep service
+</sxh>
+Show JUST the master process:
+<sxh  bash>
+ps -eo user,pid,cmd,etime,ppid | grep -v grep | grep http | grep root
+</sxh>
+Output is simlar:
+<sxh bash>
+nginx: master process /usr/  1-02:50:02
+nginx: worker process          02:50:10
+nginx: worker process          02:50:10
+nginx: worker process          02:50:10

+nginx: worker process          02:50:10
+nginx: worker process          02:50:10
+</sxh>
+The bit we are interested in is the master process:
+<sxh bash>
+nginx: master process /usr/  1-02:50:02
+</sxh>
+This represents 1 days, 2 hours, 50 mins and 2 seconds
