System settings

In MODX system settings, filter the modx3profilertoolbar namespace. The package does not create a menu item.

Keys

Key	Default	What the code does
modx3profilertoolbar.enabled	No	Turns the plugin on. On OnMODXInit it calls start() and replaceParser(). When the value is No, the plugin returns before collection.
modx3profilertoolbar.sampling_rate	100	Percent of requests for which start() reaches collection. Below 100, a skipped request gets no panel. With enabled on, replaceParser() still runs on a skipped request.
modx3profilertoolbar.frontend_toolbar	Yes	Allows the panel to be injected. Requires the web context and an mgr session.
modx3profilertoolbar.slow_query_ms	100	Slow SQL threshold in milliseconds. The rule reads the SQL row time. The result is not inserted into HTML.
modx3profilertoolbar.slow_snippet_ms	50	Slow snippet threshold in milliseconds. The rule reads events of type snippet. Collection does not add those events. The panel does not show the threshold.
modx3profilertoolbar.cli_enabled	No	When Yes, CLI collection is not rejected. The panel is injected only in the web context. The trace is not written to the database or to a file.

Who can see the data

The HTML receives JSON for the current request: times, names of collected tags, and a row with the SQL count. Individual query text and plugin names are not in that markup.

Injection runs only for a request with an mgr session. Restrict manager login.

sampling_rate reduces how many requests are collected. It does not turn off parser replacement while enabled is on.
