Inflation - tame but under control?

Since the global recovery started in the string of 2009, inflation has been moving higher. The US recession ended in June of 2009, so the rate of inflation has doubled since that time. We are not at 2008 levels, but the major economies are showing signs of rising prices. The issue is whether inflation is under control. It is tame, and it is following the path expected by central bankers, so it is hard to say that anything is out of the ordinary. The fears are not with the next two of three quarters but what will happen over the long-run, if central bankers do not start the tightening process at the right time.
