Logrotate behaviour for rules defined in multiple places

I need your help to understand logrotate behaviour .

logrotate.conf:

# 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

# use date as a suffix of the rotated file
dateext

# 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 and btmp -- we'll rotate them here
/var/log/wtmp {
    monthly
    create 0664 root utmp
    minsize 1M
    rotate 1
}

/var/log/btmp {
    missingok
    monthly
    create 0600 root utmp
    rotate 1
}

# system-specific logs may be also be configured here.

In the logrotate.d directory, I have for example one file called consul-log:

/var/log/consul {
    size 500M
    missingok
    rotate 0
    compress
    notifempty
    copytruncate
}

In the /var/lib/logrotate.status, file I can see these lines (related to the consul log file):

logrotate state -- version 2
"/var/log/consul" 2016-1-25

My question is:

  1. If I have rotate 4 inside logrotate.conf, but I have rotate 0 inside logrotate.d/consul-log, will logrotate use rotate 0 or rotate 4?

For /var/log/consul, it will use rotate 0. Quote from the man page:

Each configuration file can set global options (local definitions override global ones, and later definitions override earlier ones) and specify logfiles to rotate.

In your case, rotate 0 is both local and later.

With respect to your question:

If I have rotate 4 inside logrotate.conf, but I have rotate 0 inside logrotate.d/consul-log, will logrotate use rotate 0 or rotate 4?

logrotate.conf is the configuration file for the systemwide changes and any other configuration file which you create in the logrotate.d folder will be overriden.

Because of this directive:

# RPM packages drop log rotation information into this directory
include /etc/logrotate.d
