You can either view trace files directly in the openFT Explorer or open them in an editor after preparing them with the fttrace command. The trace files are located in the directory traces of the respective openFT instance.
Files which have the suffix .fttf are prepared directly and are display in the openFT editor when double clicking on such a file in the openFT Explorer.
Files with the suffix .fttf are protocol trace files. Their names begin with Y or S. In Windows systems, files with the suffix .PPE are interface trace files.
The names of the trace files have the following format:
Yoddhhmm.Sssccc.Pppppp.fttf
Protocol trace files for synchronous outbound requests.Soddhhmm.Sssccc.I000.fttf
Protocol trace files for the control process.Soddhhmm.Sssccc.Iiii.fttf
Protocol trace files for the server processes that handle asynchronous outbound requests and inbound requests.process-pid-thid-time.PPE (Windows systems)
Interface trace files. Here, process is the name of the process which the command has executed, pid the process ID as a hexadecimal number, thid the thread ID as a hexadecimal number and time the time in milliseconds since the system start.
Explanation for protocol trace files
oddhhmm.Sssccc
specifies the creation time of the protocol trace file. Here, o indicates the month (1
= January, 2 = February, ... A = October, B =November,
C = December), dd the day, hhmm the time in hours (hh) and minutes (mm), ssccc
the time in seconds (ss) and milliseconds (ccc).
ppppp
specifies the Process ID of the protocol trace file if Type=Y.
iii
is the index of the server process (type=S), starting with 001.
Trace files in case of errors
If a trace file cannot be written without errors due to a memory bottleneck, a message to this effect is output.
If a record of a server process trace file cannot be written as a result of an infringement of the maximum record length, the trace file is closed and the subsequent records are written to a new continuation file with the additional suffix.Liii, e.g.:
S8101010.S33222.I001.fttf (first trace file)
S8101010.S33222.I001.L001.fttf (continuation file)
