For more <i>ad hoc</i> testing, you can also determine the current value of a particular piece of instrumentation by opening a devtools console here on <code>about:glean</code> and using the <code>testGetValue()</code> API like <code>Glean.metricCategory.metricName.testGetValue()</code>.
Za dalše testy <i>ad hoc</i> móžeće tež aktualnu hódnotu wěsteho dźěla instrumentacije postajić, hdyž konsolu wuwiwarskich nastrojow tu w <code>about:glean</code> wočinjeće a API <code>testGetValue()</code> takle wužiwaće: <code>Glean.metricCategory.metricName.testGetValue()</code>.
