config.js

         // adjusted to 2.5 Mbps. This takes a value between 0 and 1 which determines
         // the probability for this to be enabled.
         // capScreenshareBitrate: 1 // 0 to disable
+
+        // Enable callstats only for a percentage of users.
+        // This takes a value between 0 and 100. A hash value is calculated using the
+        // conference name and callstats is enabled if the hash value is less than the
+        // the threshold specified here.
+        // callStatsThreshold: 5 // enable callstats for 5% of the conferences.
