As Hardware Sentry is preloaded by the PATROL Agent, it begins its operations upon the agent startup. Once the Hardware Sentry pre-discovery PSL process activates the MS_HW_MAIN class, the PATROL Agent spawns the Hardware Sentry discovery PSL process. This PSL process takes two actions: detection and environment discovery. Here is a description of this detection process.
| • | Gets the list of available connectors ("*.hdf" files in the %PATROL_HOME%/lib/MS_HW_hdf folder). |
| • | For each ".hdf" file found, tests the detection criteria (OS type, NT service, processes, SNMP request, etc.). |
| • | Marks the ".hdf" files as "detected" once all its detection criteria is met successfully. There may be several connectors detected at one time (typically: a connector for the temperatures, voltages, etc., another for the RAID disk controller and another for the non-RAID disk controller). |
| • | Launches the discovery process. |
 | To optimize the detection process and gain some time, the detection process is heavily parallelized. All the ".hdf" files are processed simultaneously. |
