Logrotate error: No file found

Question

One of our servers has a recurring error message for Logrotate.

/etc/cron.daily/logrotate: ERROR No file found for /usr/local/Zend/apache2/logs/error_log

Log rotation is working normally for the folder that it should look into. The error mentions a folder that is not monitored.

/var/log/apache2/*.log /var/log/apache2/*/*.log {
  daily
  rotate 50
  compress
  delaycompress
  missingok
  notifempty
  sharedscripts
  postrotate
        /usr/local/Zend/apache2/bin/apachectl graceful
  endscript
}

When I grep for error_log in the apache folder I find the following:

conf/extra/httpd-ssl.conf: ErrorLog "/usr/local/Zend/apache2/logs/error_log"
conf/extra/httpd-vhosts.conf: ErrorLog /www/phones/logs/error_log

Both these folders are not monitored by the httpd logrotate script. We don't use SSL, so there is no log there. The phones log is there but it not rotated currently. I've grepped the logrotate.d folder to see if some other logrotate config file monitors the apache folder, but no result.

Below the contents of /etc/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
    rotate 1
}

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

Output of /usr/sbin/logrotate /etc/logrotate.conf -d

What causes this error? I have no idea where to look.

Answer 1

I'll start from the beginning:

1. Check the call for logrotate inside /etc/cron.daily/logrotate to see if some special conf file is used. Traditionally /etc/logrotate.conf is used.
2. Inside your .conf file, look for include directive. You should have one: include /etc/logrotate.d and grep this directory for error_log. Also, check that there is no system specific logs declared inside the .conf file.

Have you found anything?

If you didn't, I suggest that you run the logrotate command found inside the /etc/cron.daily/logrotate, adding the -d switch to it.
