Regarding stats and cert.pem

[milindpatel63]

Is there any way to monitor the connection stats for the tunnel?
Like ngrok has a webui to monitor open connections...

Also,
this command "/usr/local/bin/cloudflared --config /etc/cloudflared/config.yml --origincert /etc/cloudflared/cert.pem --no-autoupdate"
has a argument for cert.pem file..
in my case, that file is missing and it says i have to do "cloudflared login" to obtain that...
but "cloudflared login" points me to cloudflare teams website where i have to add my custom domain to get that?
Am i doing this right?
is there any need for cert.pem file?
