| Console is an invaluable tool. I am not all that tech savvy, but I have learned to make use of console as a tool for giving me a heads-up on possible problems. The way I use it is by looking at 'All Messages' under the 'SYSTEM LOG QUERIES' The other important view is found by clicking the small boxed arrow at the bottom left of the window. This reveals the Senders and tags tabs. The 'Senders' can be isolated so that you might see just the items relating to that items. The other think you can do is hide 'Senders'. The console can fill up with lots of stuff, or have an ongoing category which you don't need to see. Hiding the sender will do just that. A list is maintained of the items you have hidden. So....if I see something in the list one day that looks like a problem or just keeps popping up, I will copy it....strip it of local information (time, my volume name etc) and look for it on the web. Usually there is someone else is looking for info on the same subject. Eventually you chase it down and make choices about what to do next.
So when I have a bit of spare time, I will look around in console for any anomalies, and definitely open console up when I start experiencing a problem.
The other really useful part of console is all the logging it keeps for all your system and applications.
Worth a look.

Console more or less keeps a running log in real time of all the
processes on your Mac. Each event is time-stamped. In my case I noted
several "disk 6s3 i/o error" entries, along with reams of other code I
do not understand at all. I checked Disk Utility for clues but it does
not show the device ID of the drives, just what you named them so I made
the (incorrect) assumption "disk 6s3" was my boot drive. Eventually I
discovered that you can open Terminal, type "diskutil list" and it will
return a detailed list of device ID's as well as their "names." Aha.
"Device disk 6" was that faulty Firewire drive.
By the way, along the way I bought (again) Disk Warrior which was no
help at all, booted into Safe Mode and ran the RAM hardware test
overnight, bought MORE RAM in case the whole lot was failing, and backed
up then wiped clean an SSD for the clean installation of the OS. It was
an expensive and time-consuming experience but I learned a lot.
I have always shied away from Terminal; and never used Console in my
life before a couple of weeks ago. But it turns out that with some
digging around online you can find a load of useful troubleshooting
techniques that do not put your machine in further harm's way.

Wow. Thanks for the story. Any more insight into how you used the console
to trace the problem to the disk i/o error? Sounds intriguing.

About three weeks ago I went through a major day-and-a-half battle to
get a Mac Pro 5,1 on OS 10.9.2 to behave. I was getting bizarre Finder
crashes, infinite beachballs when trying to import any element at all
into AE, even Disk Utility freezing up. I did a major update to my
backups, did a clean install of Mavericks and reinstalled all apps and
plugins one by one. That took most of a day.
However the machine was still intermittently unusable, even to the point
of refusing to Shut Down properly. Next thought was "bad RAM." I
started removing and swapping RAM sticks until I narrowed it down to the
one that seemed to be the culprit. Bam. Looking good again.
Until today when the problem recurred. Long story short, through Console
I traced the problem to a disk i/o error on an external Firewire drive.
Console is pretty great. I took the drive off-line and everything was
back to normal.
Huh. Machines.
I learned that many symptoms can be caused by many things, not always
the most "logical" or the first thing that comes to mind.
