We wanted to count the number of users hitting the application on
tomcat/Apache , as an example for today how many users hits/send
request to the application
Requests != users.
How shall we check this request , please suggest.
I think you need to have a more well-defined question.
For example:
For a given day, we'd like to know how many requests we get per-minute,
so we want data that looks like this:
date,hour,minute,request_count
2022-09-08,00,01,123
2022-09-08,00,02,456
2022-09-08,00,03,789
2022-09-08,00,04,876
2022-09-08,00,05,256
...
If you want to know the number of users, you'll have to define "user".
And you probably won't be able to get that information from the
access-log without some additional work. If you mean "established user
session", then you'll have to probe Tomcat to find out how many sessions
exist on whatever schedule you want. If you mean "established session
with authentication" then you'll have to do a different kind of probe.
If you want to know how many unique authenticated-users made requests
during a specific minute, that's yet another question and one that CAN
be answered by looking at the access-log, as long as you add some
convenient information to it (the user principal) and then use some
text-processing tools to collate the information.

Can we do it from Apache access logs?
Sure.
$ grep '08/Sep/2022:14:32:' access.log | wc
Version
* Tomcat 8.5.5
Ouch. That version is 6 years old with published security vulnerabilities. I
strongly suggest that you upgrade ASAP.
* Apache 2.4
I'm gonna guess that this is out-of-date, too. Latest is 2.4.54 from back in
June 2022.
