Mongostat not displaying inserts to time series?

Question

I'm using MongoDB 5.0.2 and mongostat 100.5.0, and I notice that I'm not able to monitor insert for time series, or at least they do not show up. Is there either some way to enable this, or to monitor it elsewhere?

It does seem like net_in is affected by the inserts. E.g., doing approx 10 000 inserts per second:

insert query update delete getmore command dirty used flushes vsize   res qrw arw net_in net_out conn                time
    *0    *0     *0     *0       0     2|0  0.7% 8.3%       0 4.63G 2.94G 0|0 1|1  1.32m    284k   90 Sep 20 16:14:25.144
