      Today I wanted to use command monitoring to prove that a command was sent to a secondary, so I thought I'd so something like:

      const client = new MongoClient(..., { monitorCommands: true });

const bag = [];
client.on('commandStarted', filterForCommands(['count'], bag));
await client.connect();
await client.collection.find().count();

const td = client.topology.description;
const sd = td.servers.get(bag[0].address);
...

       

      Except this doesn't work for me on localhost because the TopologyDescription has all the servers listed by their seed names (localhost:31000, localhost:31001, localhost:31002) but the command monitoring event uses a resolved address of the connection (127.0.0.1:31002).

      We should ensure that people can trace commands consistently across all of our events.
