3.2. Logging
3.2.1. General
The CORTEX CRT Quantum reports on the Logging port all changes in its configuration, as well as satellite TC
requests, TC instructions and associated acknowledgement messages exchanged over the Telecommand port.
It is also possible to log 4 specific monitoring flows (SPS Kernel ≥ e3r9)
Up to five Logging Clients can be simultaneously connected to the Logging port. For more detail on the contents
of the logging messages, refer to Annex 1.
3.2.2. Storage of Logging Data
Logging messages (configuration changes and telecommanding messages) can be stored in a FIFO-structured
file (circular buffer) on the hard disk.
TCP-IP logging messages are directly stored to the disk (messages are not re-shaped). See Annex 1
(STI100013_TTC, Section 2.8.2) for a detailed description of the logging messages.
TCP-IP messages are not divisible: if a message cannot be entirely stored at the end of the file (not enough
space left), it will be stored from the beginning of the file.
The storage function can be enabled/disabled and the file size changed in the Windows registry (see section
4.2.8.7.2).
If the registry key “StoreTotal” is created, the first file is overwritten when the maximum size has been reached.
3.2.3. Additional Flows Logging
A text file located on the hard disk (see “FileConfig” in section 4.2.8.7.2) contains the STI status to be logged and
the sampling rate.
Refer to STI 100013, Section 2.4.3 to see how to start/stop the storage of these additional flows.
