[checkmk-commits] Huge refactoring of Check_MK base data fetching

Module: check_mk Branch: master Commit: 203bfd8a62df19dd07a1ee8b9a97dbb3fba60372 URL: http://git.mathias-kettner.de/git/?p=check_mk.git;a=commit;h=203bfd8a62df19… Author: Lars Michelsen <lm(a)mathias-kettner.de> Date: Thu Nov 9 10:30:37 2017 +0100 Huge refactoring of Check_MK base data fetching * Flipped the data gathering structure. It was first iterating over all check types and fetching the (agent) data on demand during the first check and caching these results to reuse it for the other checks. This has been changed into two phases: 1. Fetch ALL data (including SNMP scan + walks) 2. Execute discovery/check/inventory logic * Abstracted collection of data A new concept of "data sources" has been introduced. Each source of monitoring data is a data source. The following exist at the moment: TCPDataSource SNMPDataSource SNMPManagementBoardDataSource PiggyBackDataSource DSProgramDataSource SpecialAgentDataSource * With the above changes we have a far better situation now a) Exception handling (-> error reporting) is equal for all sources b) Caching of raw source data is exactly the same * This prepares the way for splitting up data fetching, which also includes expensive timeouts, from the check execution.
