title: OpenTsdb: Is Space character allowed in Metric and tag information
body: <p>I was working with openTsdb and came across with the issue that space character is not allowed in metric, tag(tagk) and even the values(tagv). Is there any way we can add space atleast in the value of tag?</p>
  
  <p>I also referred: <a href="http://opentsdb.net/docs/build/html/user_guide/writing/index.html#metrics-and-tags" rel="nofollow noreferrer">http://opentsdb.net/docs/build/html/user_guide/writing/index.html#metrics-and-tags</a></p>
