Definitions

  • the present invention relates to an integrated documentation system with a time-indexed relational database system, as well as an associated database system and ner procedures for setting information content in the database system for automatically supported documentation of information technology systems (IT).
  • IT information technology systems
  • IT system documentation encompasses all aspects of the documentation required for the operation of IT systems. This includes the creation and updating of the information, the establishment of an outline structure for the documents and the provision of the documentation as part of the operational management.
  • BESTATIGU ⁇ GSKOPIE Integrate documentation into the existing operational management environment, which is usually supported by the use of different system management tools.
  • the desired information should be able to be brought into a suitable structure. For example, it is helpful if a server description on the topic of network not only lists the information from the server operating system on this topic, but also uses other information sources, such as information from the network switch to which this server is connected. Good documentation should therefore make information from different sources usable, ie access to information that is as cross-platform and cross-system as possible should be guaranteed.
  • documentation should ultimately fulfill two tasks: On the one hand, it serves as evidence of conditions in the past. On the other hand, documentation of the desired state and the actual state as it is is the basis for efficient system management of the IT system concerned.
  • Good documentation should therefore have an archiving function for states at different times in the past.
  • an IT system for example due to its large number of different operating systems and components, is a very heterogeneous system. This will not change in the foreseeable future either, since the decision strategy for the use of IT Systems, etc., reasonably follows a top-down approach according to the following table on the decision strategy for the use of IT systems:
  • Table 2 System management with an information platform
  • the documentation document is usually created using a word processing program or an HTML editor, i.e. the documentation is created as a static document in a specific text format. This approach therefore does not offer a time dimension within the documentation. Rather, the time required for the creation of these documents means that they do not even correspond to the actual state on the computer systems.
  • the first documentation i.e. the one-time creation of the documentation, which describes the state of this computer system at the time of commissioning, estimates approx. 2-5% of the hardware costs. For medium-sized computer systems this is an effort of approx. 5 person days.
  • the update of this documentation that is necessary over time can be estimated at a cost of approx. 0.5 to 1 person-day per month and server system.
  • the documentation system must also provide documentation about time as a basic, transparent functionality
  • the volume of data resulting from the documentation over time must remain technically manageable the access behavior, in particular the time behavior to the data volume resulting from the documentation over time, must be implemented efficiently
  • the data volume of the information platform is a critical factor here, as the following estimates for a "small” and a “large” variant explain when used in a data center over a year:
  • Table 3 Data volume in a so-called "small” variant of an IT system to be documented over time
  • Table 4 Data volume in a "large" variant of an IT system to be documented over time
  • Table 5 Number of data entries in a "small" variant of an IT system to be documented over time
  • Table 6 Number of data entries in a "large" variant of an IT system to be documented over time
  • a time-indexed relational database system for an integrated documentation system for the automatic documentation of an information technology system preferably a network or a software system
  • the database system is set up to store information content about the information technology system and its respective history of origin, and information content and Information content creation history is stored in separate areas, preferably files or tables, of the database system, whereby from the information content creation history area to the information content area there is a 1: 1 relation, the different database system entries in the information content creation history area then on the same Entry in the information Mationsinhalt-area refers if the information content at the time of creating the later entry in the information content creation history area was the same.
  • the database system is also set up to store information components in a separate information components area, with a 1: N relation from the information components area to the information content creation history area, the database system entries in the information components area then referring to an entry in the information content area.
  • Origin history area refers if, at the time of creating the entry in the information content origin history area, related information content was documented by an entry in the information content area that contains these information components.
  • the time-indexed relational database system for an integrated documentation system can also be characterized according to the invention in that the database system is also set up for storing subsystem data, preferably data about network computer systems or software modules, in a separate subsystem data area and from the subsystem data area to the information content - Creation history area is a 1: N relation, the database system entries in the subsystem area then refer to an entry in the information content creation history area if the associated information content in the information te area relate to the subsystem, the entry of which in the subsystem area refers to the information content creation history area.
  • subsystem data preferably data about network computer systems or software modules
  • the database system can also be set up to store job data in a separate job data area, there being a 1: N relation from the job data area to the information content creation history area, the database system entries in the job data area then referring to an entry in the information content area.
  • Origin history area refers if the database entries in the information content origin history area are related to each other in time.
  • N relation between the time in the job data area and information management in the information content creation history area has an influence on the access time.
  • the common application that all information that was entered in the job data area at a certain point in time should also be displayed together, is represented by the relation and allows access to all related information content and / or information components via the information content creation history area through a single database access.
  • the above embodiments of the database system according to the invention thus enable a method according to the invention for the volume-reducing setting of information content via an information technology system in a database system according to one of the embodiments described above, the information content to be set via the information technology system initially having the information content about the information technology system already stored in the database System are compared and in the case of a match instead of the information content to be set itself, only an entry in the information content creation history area is set with reference to the entry found as matching in the information content area.
  • the information content to be set is compared with the information content already stored on the basis of the entries in the information content creation history area in reverse chronological order, the comparison taking place in reverse chronological order preferably taking place only up to a specified limit in the chronology.
  • the chronological limit is particularly preferably only one step.
  • a method for automatic time-indicated documentation of the information technology system by means of a database system according to the last embodiment described above for documenting an information technology system preferably operates
  • the present invention thus teaches an integrated documentation system with a time-indexed relational database system with a computer, which is set up programmatically in such a way that it has a database system according to the present invention, and at least one software module which operates according to a method according to the present invention ,
  • the methods according to the present invention can of course also be present as a computer program which has instructions which are set up here for carrying out the method according to the invention.
  • the integrated documentation system with time-indexed relational database system offers a number of advantageous applications, such as:
  • the integrated documentation system automates the complete system documentation in IT data centers.
  • the single point of information thus achieved offers for the first time cross-platform access to the temporal development of all recorded data and information and thereby realizes revision-proof documentation over time.
  • flexible comparison functions streamline troubleshooting and maximize availability.
  • the possibility of offline communication also enables use in sensitive security areas as well as in the context of service and support tasks, for which there is no permanent network connection to the individual computer systems.
  • the complete database of the single point of information can preferably be selected according to hardware and software components using freely definable filters.
  • the system uses this hit list to create an up-to-date, revision-proof inventory and asset management.
  • the resulting transparency in the entire IT area reliably reveals hidden optimization potential.
  • the system Due to the historical data management, the system also enables the automatic creation of utilization diagrams for any system parameters, which in turn enables easy-to-use long-term monitoring.
  • trends are recognized and forecasts made. For example, from the development of the degree of filling of plate systems to the point in time be closed, for which the system will no longer have free disk space.
  • These evaluations can in turn be made available online to the help desk staff.
  • the system according to the present invention is also able to implement change monitoring for system-critical resources.
  • the automatically generated reports create transparency in the IT data center and enable efficient capacity planning and profitability analysis.
  • a central, cross-platform software distribution is implemented both for the components of the system according to the invention and for third-party products.
  • the system supports the complete cycle from planning to distribution and installation to report generation.
  • the integrated documentation system with time-indexed relational database system can be used for auditing login processes and activities on IT systems.
  • the documentation system forms the basis of change and configuration management. It generates the evaluations and analyzes required for decision-making purposes, records the actual conditions before or after the controlled action and carries out the final comparisons necessary for the final inspection.
  • the integrated documentation system with time-indexed relational database system can be used for asset management of IT systems;
  • a specific mechanism for the detection of hardware components is used so that the changes, for example the reinstallation of a computer with the assignment of a new host name and a new network address, are recognized and the information in the database can be assigned to the correct computer entry auditing Server by using a specific agent, the integrated documentation system with time-indexed relational database system can be used for auditing login processes and activities on IT systems - for project documentation
  • the integrated documentation system with time-indexed relational database system can be used for the documentation and monitoring of plant controls
  • the routine can be used via the $ limit parameter for a complete storage as well as for a single storage of information entries over the entire acquisition period.
  • the method according to the invention is transparent with regard to access to the information, because the data reduction is implicitly represented by the 1: 1 relation.
  • the information content is always accessed via the 1: 1 relation between history_t and text_t. This access does not differentiate between information content used once and repeatedly.
  • N relation between the time in the job data area and information management in the information content creation history area has an influence on the access time.
  • the common application that all information that was entered in the job data area at a certain point in time should also be displayed together, is represented by the relation and allows access to all related information content and / or information components via the information content creation history area through a single database access.
  • This type of time-indexed data management thus both reduces the data volume and lays the foundation for efficient and high-performance access to the information components.
  • Another important aspect is the integration of automatically recorded information components with manually created information, because in addition to automatically recorded information components, manually generated explanations etc. are always necessary to understand documentation.
  • a second entry with the value zero enables the configuration of a second root account, i.e. the admin user has the same rights as the root user.
  • This data model is implemented by communication modules that are implemented in a protocol-specific manner. By using the agent technology, information components beyond the standard protocols can be recorded.
  • the data modeling for the database system creates the prerequisites for the transparent depiction of all information components in the database system, regardless of the way in which the information is recorded.
  • TCP / IP protocol family such as HTTP, LDAP, TELNET, FTP etc.
  • the automation of the information query is implemented by a central control of all query operations by the documentation system, preferably the documentation server.
  • This decoupling of the two communication levels enables flexible information retrieval with regard to the complete recording of all information components in a network, which at the same time offers the necessary transparency for the logical communication level.
  • the format of the control file and the result file on the logical communication level on the one hand enables the transfer of all types of information regardless of the form of communication on the physical level, and on the other hand the format of the control file enables the simple transfer of commands and the transfer of script or the binary files that are required to execute the respective commands.
  • the flexibility of the communication mechanism is thus transferred to the administration level, since no separate software distribution for specific auxiliary commands or for updating the agent has to be implemented.
  • presentation system of the documentation system should be designed as a user- and application-oriented, integrative presentation system. The following requirements arise here:
  • the display system should preferably integrate all of the information components desired by the user. Also preferably all information components should be made available to different user groups in any view. Newly defined perspectives should preferably also be applicable to information components recorded in the past.
  • the display system should therefore be able to summarize all information components flexibly and freely, but without achieving this through redundancy in data management, as well as being able to fulfill all user requests with regard to the document structure and the documentation content.
  • N N relation between computers in the subsystem area (preferably in the host_t table) and points of view in a point of view area (preferably in a view_t table)
  • N Relation between the structure points in the structure area (preferably in the structure_t table) and the information components in the information area (preferably in the info_t table)
  • M N Relation between the information components in the information components area (preferably) in the table info_t and operating systems in an operating system area (preferably in the table os__t); the M: N assignment required for this is implemented by the command area (preferably by the table) and carries the operating system and protocol-specific commands as attributes, for example the command df-k for a Unix system and the command sy for a Windows system sinfo-drivers and for an SNMP device the OIDsystem.sysName.O
