problem: Not showing online status: OpenSSH user login

on a server with these specifications
OS: Debian 10 buster
Kernel: x86_64 Linux 4.19.0-23-amd64
Packages: 747
Shell: bash 5.0.3
CPU: Intel Xeon E-2336 CPU @ 2x 2.904GHz
RAM: 417MiB / 986MiB

I rebooted the server several times.
I changed the SSH port.
I even put four ports in the settings.

What is the solution?

It does not display online users.

===========================================
-----=[ Dropbear User Login ]=-----
ID | Username | IP Address

grep: (standard input): binary file matches
-----=[ OpenSSH User Login ]=-----
ID | Username | IP Address

grep: (standard input): binary file matches

How can this problem be solved?

I saw the best performance of this project on ubuntu 20 and debian 9, test it

There is no problem in Debin 11.
If you have many users, be sure to upgrade the RAM to at least two cores and the CPU to two cores.
If you use three CPU cores, you will have much better quality.

• Although the use of old operating systems creates better performance and less resources, it is not recommended at all in terms of security.

Thanks for the suggestion

the problem solved with these commands:

sudo rm -f /var/run/utmp
sudo rm -f /var/log/wtmp
sudo rm -f /var/log/btmp
sudo apt-get update
sudo apt-get upgrade openssh-server
