Subject: text protocol: Add support for meta_data in PUTVAL
X-Git-Tag: collectd-5.11.0~20^2~10
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6c3106f61987a975dce7faed29c298cbeda0cfa8;p=thirdparty%2Fcollectd.git

text protocol: Add support for meta_data in PUTVAL

This adds the support for string meta_data in PUTVAL. This allows users
to send meta_data using either the unixsock plugin or the exec plugin.

The meta_data is specified using options of the form meta:<KEY>=<VALUE>.
As an example, meta:foo=bar will add an entry with key "foo" and value
"bar".
