OpenTsdb: Is Space character allowed in Metric and tag information

问题

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?

I also referred: http://opentsdb.net/docs/build/html/user_guide/writing/index.html#metrics-and-tags

回答1:

Spaces are not allowed.

As per the documentation you referred:

Only the following characters are allowed: a to z, A to Z, 0 to 9, -, _, ., / or Unicode letters (as per the specification)

I suggest you should use '_' in stead of spaces.

回答2:

As of opentsdb version 2.3 there is support for specifying additional characters to allow via the config variable

tsd.core.tag.allow_specialchars = !@#$%^&*()_+{}|: <>?~`-=[]\;',./°

http://opentsdb.net/docs/build/html/user_guide/configuration.html gives more details
