Yes, there is a meter to this line.
Given that there are 8 syllables in this line, that would mean this is a tetrameter. One meter consists of 2 syllables, so if there are 8 syllables in a line, that would mean there are 4 meters, which in literature is called a tetrameter.

So, this line is written in<u> </u><u>iambic tetrameter. </u><u />
