Different ports for different sources

How can I сonfigure expose different ports for different sources? For example:

espose port 24231 for tail file /var/log/nginx/access1.log

```

@type prometheus_tail_monitor

@type prometheus
port 24231

@type tail

@type regexp
expression /^(?[^ ]*) \[(?[^ ]*)\] (?[^ ]*) (?[^ ]*) \[(?[^\]]*)\] \"(?\w+)(?:\s+(?[^\"]*?)(?:\s+\S*)?)?\" (?[^ ]*) (?[^ ]*)(?:\s"(?[^\"]*)") "(?[^\"]*)" (?[^ ]*)$/
time_format %d/%b/%Y:%H:%M:%S %z
keep_time_key true
types size:integer,reqtime:float,uct:float,uht:float,urt:float

tag nginx1.default
path /var/log/nginx/access1.log
pos_file /tmp/fluent_nginx1.pos

@type prometheus

name nginx_size_bytes_total
type counter
desc nginx bytes sent

site default

key size

```
and espose port 24232 for tail file /var/log/nginx/access2.log

```

@type prometheus_tail_monitor

@type prometheus
port 24232

@type tail

@type regexp
expression /^(?[^ ]*) \[(?[^ ]*)\] (?[^ ]*) (?[^ ]*) \[(?[^\]]*)\] \"(?\w+)(?:\s+(?[^\"]*?)(?:\s+\S*)?)?\" (?[^ ]*) (?[^ ]*)(?:\s"(?[^\"]*)") "(?[^\"]*)" (?[^ ]*)$/
time_format %d/%b/%Y:%H:%M:%S %z
keep_time_key true
types size:integer,reqtime:float,uct:float,uht:float,urt:float

tag nginx2.default
path /var/log/nginx/access2.log
pos_file /tmp/fluent_nginx2.pos

@type prometheus

name nginx_size_bytes_total
type counter
desc nginx bytes sent

site default

key size

```
I want to see metric from file /var/log/nginx/access1.log in http://localhost:24231/metrics
and metric from file /var/log/nginx/access2.log in http://localhost:24232/metrics
