PySyMo is a web-interface for view and analyze syslog data stored in MongoDB.

https://github.com/icoz/pysymo

• Python >= 2.6
• Python packages:
  • Flask, Flask-WTF, Jinja2, WTForms - flask base
  • pymongo - work with MongoDB
  • flup - run pysymo via fcgi
  • flask-paginate (> 0.2) - output data pagination
  • flask-login - user login
  • pycrypto - password protection
  • python-ldap - LDAP authentication
  • Babel, Flask-Babel - i18n
• MongoDB
• Web-server
• Linux logging system (syslog-ng, ...)

Pysymo is a web-interface for view and analyze syslog data stored in MongoDB. There are two main things:

• Store syslog data in MongoDB. Different distributions use different logging system (SUSE - syslog-ng, Arch - journald, Ubuntu - rsyslog). So you need a way to write to MongoDB from your syslog system by piper script or by MongoDB driver built-in in you syslog system.
• View stored data by web-interface based on Flask. You can use any web-server you like.

1. Install requirements.
2. Config MongoDB database.
   • Change MONGO_DATABASE in app/db.py, tools/config.py if necessary.
   • Init database using tools/initdb.py.
   • Init MEDB (message explanation database) using tools/init_medb.py.
3. Config LDAP in config.py if necessary.
4. Config AppArmor (if exists). See example in examples/apparmor/sbin.syslog-ng.
5. Config logging system to store in MongoDB.
   • example for syslog-ng 2.x in examples/syslog-ng-2.x/syslog-ng.conf.
   • example for syslog-ng 3.x in examples/syslog-ng-3.x/syslog-ng.conf.
   • example for rsyslog in examples/rsyslog/pysymo.conf.
     • syslog process must have rights to run piper script!
6. Config web-server to run pysymo.fcgi. See example for lighttpd in examples/lighttpd/fastcgi.conf .
7. Config logging (config['PYSYMO_LOG'], tools/config['PYSYMO_ERROR_LOG']) directory and set write permissions for web-server and syslog process.
8. Config crontab to run periodic tasks: tools/refresh_cache.py, tools/refresh_charts.py.

• plain - user and password stored in MongoDB. Registration needed and must be enabled.
• ldap - user and password stored in LDAP. No registration needed.

If you want to use LDAP to authenticate users, you need to config some parameters in config.py.

• LDAP_SERVER = 'ldap://[ldap_server]' (ex: 'ldap://ldap.office.mycompany.com')
• LDAP_SEARCH_BASE = '[organisation]' (ex: 'o=myorganisation')
• LDAP_SERVICE_USER = '[service_user_dn]' (ex: 'cn=pysymoauth,ou=myunit,o=myorganisation')
• LDAP_SERVICE_PASSWORD = '[password]'

Some syslog messages includes message code (vendor specific), that can be explained in detail. MEDB consists codes and descriptions, currently only for Cisco.

MEDB.txt file format:

([message id], [short description], [long description], [action])

See Cisco ASA message codes: http://www.cisco.com/c/en/us/td/docs/security/asa/syslog-guide/syslogs/logmsgs.html

• /app/ - flask app
• /data/ - various datafiles
• /examples/ - configuration examples
• /tools/ - tools scripts
  • config.py - config for tools scripts
  • fill_db.py - fill database with random records. For debug use only.
  • init_db.py - db init script, creates collections and indexes. Use once during installation.
  • init_medb.py - medb init script, creates collection 'medb' and fills it with data/medb.zip file. Use once during installation.
  • refresh_cache.py - caching script, creates lists of hosts, applications, facilities displayed in web-interface. Use in crontab.
  • refresh_charts.py - chart script, aggregates data to create charts. Use in crontab.
  • syslog_piper.py - script to store syslog data to MongoDB. Use with rsyslog, syslog-ng 2.x
• config.py - main config
• pysymo.fcgi - run pysymo with web-server
• run.py - run pysymo standalone on localhost
