Grafana logs to syslog server and specify port?

We would like to send Grafana system logs to our syslog server. However, I need to do it on a non standard port, for example 1518. What would I specify inside of custom.ini to achieve this?

[log]
# Either "console", "file", "syslog". Default is console and  file
# Use space to separate multiple modes, e.g. "console file"
mode = syslog
# Either "debug", "info", "warn", "error", "critical", default is "info"
level = info

[log.syslog]
;level =

# log line format, valid options are text, console and json
format = text

# Syslog network type and address. This can be udp, tcp, or unix. If left blank, the default unix endpoints will be used.
;network =
address = 10.10.1.57

# Syslog facility. user, daemon and local0 through local7 are valid.
;facility =
# Syslog tag. By default, the process' argv[0] is used.
;tag =

I am also intereted in this. Is it possible?

looks like every thing is formated in the way of
IPaddress:port
image

Yes, for example:

[log.syslog]
format = json
network = tcp
address = "opentelemetry-collector:54526"
