2014-06-01: Version 0.1.0

This is the initial release of SysDB. It provides the following core features:

  • sysdb: A terminal-based, interactive client program. Supports line-editing and history based on libreadline or libedit and uses an asynchronous, event-driven architecture to handle user input and server replies simultaneously.

  • sysdbd: The database backend service configurable through a configuration file. The daemon supports online reconfiguration.

  • core: Flexible, multi-threaded core architecture providing a configurable plugin infrastructure for querying external data-sources and extending core functionality. The following plugin types are supported:

    • data collection

    • hostname canonicalization

    • logging

  • store: Central, in-memory object store managing host and service objects and their attributes. Host names may be canonicalized through respective plugins. Each object is automatically attributed with last update and interval information using nano-seconds resolution. Attributes may have various types (integer, decimal, string, date-time, binary).

  • frontend: The frontend handling client connections uses a multi-threaded, asynchronous, event-driven architecture capable of handling multiple listen addresses.

  • query language: The store may be queried using the ‘LIST’, ‘LOOKUP’, and ‘FETCH’ commands returning JSON formatted objects.

  • utils: A rich set of abstract data-types and utility functions for internal use:

    • generic channels for asynchronous, multi-threaded I/O

    • DBI wrapper to ease common database access operations

    • thread-aware error handling and reporting

    • doubly linked-lists

    • dynamic sized memory buffers supporting formatted strings and binary

    • data

    • UNIX socket client implementation

  • documentation: Full documentation for the tools, all plugins, and the query language provided as manpages and HTML pages.

  • testing: Unit and integration tests exist for most parts except plugins covering 77% of all functions. Valgrind and Clang’s address sanitzer are used to detect memory leaks and programming errors.

The following plugins are shipped with this version of SysDB:


  • collectd::unixsock: Query collectd through its ‘unixsock’ interface

  • mk-livestatus: Query arbitrary (monitoring) systems using the Check_MK Livestatus interface.

  • puppet::store-configs: Query Puppet through its “stored configuration” database.


  • cname::dns: Canonicalize hostnames by querying DNS information.

  • syslog: Send log messages to the system log service.
