The compatibility problem occurs when we fix the type of metrics. I'm
planning to look into that soon, but it is orthogonal to this branch (though
this branch is the reason we are fixing the types).
> replace XML statistics with Lua
> -------------------------------
>
> Key: TS-4099
> URL: https://issues.apache.org/jira/browse/TS-4099
> Project: Traffic Server
> Issue Type: New Feature
> Components: Lua, Manager, Metrics
> Reporter: James Peach
> Assignee: James Peach
> Fix For: 6.2.0
>
>
> The custom metrics XML format is undocumented and difficult to use and
> extend. Since we plan to use Lua for configuration programmability, lets make
> a start by replacing this subsystem with Lua.
> It turns out that Lua is mostly more readable and easier to understand.
> Performance is roughly similar.
> Example syntax:
> {code}
> float 'proxy.node.user_agent_total_bytes_avg_10s' [[
> local self = ...
> return interval_delta_of_10s(self, function()
> return proxy.node.user_agent_total_bytes
> end)
> ]]
> counter 'proxy.node.origin_server_total_bytes' [[
> return proxy.node.http.origin_server_total_request_bytes +
> proxy.node.http.origin_server_total_response_bytes +
> proxy.node.http.parent_proxy_total_request_bytes +
> proxy.node.http.parent_proxy_total_response_bytes
> ]]
> {code}
