Hi all,
Sure, I can put in what I understand of these columns.
The biggest mistake that we see customers make is that they think that the B.01, B.10, and B.60 columns directly translate to CPU usage and capacity. In fact all that they are showing is the amount of time during the last 1 minutes, 10 minutes, and 60 minutes respectively that the process was working.
For example, if you are looking at the B.10 column and it shows 50 for WP1, that simply means that WP was working for 5 minutes of the last 10 minutes. It doesn't really have anything to do with capacity - in fact it could be that they were running one database statement for 5 minutes and it would show 50 for the B.10 column (hopefully if a single db statement is taking 5 minutes, you are aware of what is causing it ;)), or it could be that it ran 300 things that took 1 second each or 3000 things that took .1 seconds each.
Should you be alarmed at a high number in the B.01, B.10, and B.60 columns?
Not necessarily. If there are no other symptoms accompanying this, there's probably nothing to worry about. If there's no high CPU usage at the same time for the processes, there's probably nothing to worry about. If the B.01 is at 100, but the B.10 is at 1, and the B.60 is at 1, there's probably nothing to worry about.
When should you be concerned?
If there's a large upswing in the numbers very suddenly. For example, if your B.01, B.10, and B.60 are usually at a relatively low level and then are consistently higher (perhaps after a restart or slowdown of some sort) and don't go down, you should probably contact Support.
Usually, there's no reason to panic if the numbers are higher than you think they should be. I think there's only been five or six times over the last eight years that I've seen a correlation between the Usage columns and actual problems with the Automation Engine. Usually we'll notice other behaviors before checking the usage columns.
