Your approach right now is correct. And what ever you are telling seems strange ?! As because changing entry for this log rotation will not harm the others normally.
# see "man logrotate" for details
# rotate log files weekly
weekly
# keep 4 weeks worth of backlogs
rotate 4
# create new (empty) log files after rotating old ones
create
# uncomment this if you want your log files compressed
#compress
# RPM packages drop log rotation information into this directory
include /etc/logrotate.d
# no packages own wtmp -- we'll rotate them here
/var/log/wtmp {
monthly
create 0664 root utmp
rotate 1
}
# system-specific logs may be also be configured here.
/var/log/testlog/debug_log {
daily
rotate 7
create
compress
}
pls let me know if it possible to rotate /var/log/messages - weekly
& /var/log/custom-log - daily ?
