5.1.1 Syslog

syslog (actually RSYSLOG: see man rsyslogd (8) and LOGRORATE: see man logrotate (8)) is used by all MEDIATEX’s binaries and scripts.

3 environment variables manage the content to log:

• MDTX_LOG_FACILITY
• MDTX_LOG_FILE
• MDTX_LOG_SEVERITY

These variables are overwritten when using the corresponding command line options (see Options).

• Events in

  log_message()

  from all processes

• Processing

  Log the activity (and rotate the logs).

• Events out

  $ mediatex upload[+] [file file [as target]]* [catalog file] [rules file] to coll coll

  to uploadClient (see uploadClient): upload collection’s APACHE access logs to the cache so as to backup them.

• Data in

  /etc/rsyslog.d/mediatex_log.conf

  local2.info /var/log/mediatex.log
  

  Notice: This configuration tel RSYSLOG to ignore debug messages (even if MEDIATEX send debug messages, you will not get them). The higher the level is and the less messages you get: err > warning > notice > info > debug

  /etc/rsyslog.conf

  Also, RSYSLOG will drop messages when they are coming too quickly, and you may want to change this setting (see Reporting bugs).

  /etc/logrotate.d/mediatex_logrotate.conf

  Manage MEDIATEX’s logs rotation.

  /etc/logrotate.d/httpd-prerotate/mediatex_logrotate

  Filtre and upload the Apache (see Apache)’s latest logs to the related collections, after rotation, if enabled into /etc/mediatex/mdtx-COLL/servers.txt (see servers.txt).

  /var/log/apache2/access.log
