Are you looking for what types of metrics you should use or the results of common metrics that are applied?
As far as something like the "number of bugs found in the fieald add [sic] didn't found in the QA lab" that will be totally dependent upon the organization. There is no absolute value to this metric because it depends on how the testing was carried out as well as a lot of other variables (such as how much time was given to test).
As far as metrics related to completing tests in a certain time period as was mentioned in a previous post, this, again, depends on a lot of factors including the type of testing you are doing (regression, fucntional/behavioral, performance, etc).
Finding defects is another area where metrics certainly apply but I am not sure, based on your question, what you are looking for. For example, one metric is the number of defects that have to be re-opened from one build to another. In other words, it was fixed before but now it is broken again. That is a valuable metric. If you are asking about specific numbers for that metric (i.e., what is the "normal" value for it), again, that depends on the organization.
I know I am not answering your question adequately but even with Palani's clarification I am still not quite sure what is being asked for here.
