Is there a way to use dots in tags in query aliases in OpenTSDB query (e.g. $tag_addr.router)?
Because we have metric names like ‘protocol’, ‘addr.router’, ‘addr.src’. And when I use $tag_protocol in the query alias, then in the legend it is correctly shown as ‘UDP’, ‘TCP’, … But when I use $tag_addr.router, then the legend shows $tag_addr.router. I even tried using backslash ($tag_addr.router), but it didn’t help.
