We'd like to enable the instrumentation for the sidebar prior to deploying the features to our test wikis to ensure the event rate is within bounds

This is live on the part 1 wikis. Before proceeding with enabling on part 2 wikis we should validate that the throughput matches our original estimations
French Wikipedia gets 26.1 million views an hour. French Wiktionary gets 1.3m. Based on that 1.3/26.1 that’s 5% of the traffic.
So X / 0.05 = Y
where Y = “predicted number of events per hour on fr.wikipedia” and X = “number of events per hour on fr.wiktionary”.
Per analytics and @Ottomata (T250282#6119734) “VirtualPageView does around 1000 events per second. Ideally yours would do not more than that, hopefully less, but if we need to go bigger it is possible.”
So we want to make sure (( X * 0.05) / 60 / 60 < 1000) (X = number of events per hour on fr.wiktionary) before continuing.
@Mayakp.wiki reports that we should expect around 362 init events per sec from French Wikipedia so I think we're good to continue here with the 20% sampling rate.

Mentioned in SAL (#wikimedia-operations) [2020-07-27T18:29:15Z] <catrope@deploy1001> Synchronized wmf-config/InitialiseSettings.php: Enable desktop web UI click tracking instrumentation on frwiki, hewiki, fawiki (T258058) (duration: 00m 56s)
I'm seeing about 7 events per second at the moment on this graph:
https://grafana.wikimedia.org/d/000000566/overview?panelId=23&fullscreen&orgId=1
@Mayakp.wiki let's sync once we have 2 days of data and can verify that we're seeing instrumentation data for all the wikis before signing off.
The number of events have picked up as of today. Here's the break up by day and wiki.
Based on the pageviews per hour dashboard for the 6 test wikis (fr.wikipedia, fr.wiktionary, pt.wikiversity, fa.wiki, he.wiki, eu.wiki) on Turnilo, I wanted to correct this to ~30 events per sec with 20% sampling. This is close to what we see in Eventlogging.
Resolving this. Instrumentation is enabled. Further QA can be tracked in T256075: Post Deployment Data QA - Collapsible Sidebar Instrumentation
