5.4.4.3 Usage Considerations

This section identifies special considerations or techniques
related to using the TCPFCF file.  In addition, several
retrieval examples are provided to facilitate the use of this
file.


In the examples, a SAS macro variable is used to specify the
DDname part of the CA MICS file name. These macro variables
are a standard part of CA MICS and are available for all
files. The macro variable name has the form &diiit, where d
is the database identifier, iii is the information area
name, and t is the timespan.  For the examples, a database
identifier of P is used.  The identifier is installation
dependent, so you should find out what the identifiers are at
your installation.

Special Considerations/Techniques

1. FTP Server File                FTP Client File
      (TCPFSF)                       (TCPFCF)
   -------------------------      ------------------------
   SMF 118 FTP Server record      SMF 118 FTP Client record
   FTP ID = 'S' at offset 72      FTP ID = 'C' at offset 72
 
   SMF 119 subtype 70 (FTP        SMF 119 subtype 3 (FTP
   Server completion record)      Client completion record)
 
   Care must be exercised when analyzing any FTP command data
   which is the result of FTP data transfer from one MVS
   system to another within one domain.  A SMF type 118
   record is logged into both the originating host and the
   destination host.  The originator host logs an entry as
   Client and the destination host logs the same entry as
   Server.  However, these log records represent different
   domains.

2. Care must be exercised in using the special date and time
   data elements contained in each CA MICS file. As file
   granularity increases in higher timespans, certain fields
   lose significance and should not be used in those cases.

   o HOUR should not be used in MONTHS.
   o DAY and DAYNAME should not be used in WEEKS or MONTHS.
   o WEEKS should not be used in MONTHS.

3. The following data elements are user-defined.  The value
   in each depends on user-selected options or user-supplied
   SAS code:

   o NETWRKID - Network Identifier.  A one to eight-character
     descriptive name for each network represented in the
     data.  NETWRKID is set in the Network Identifier Exit
     Routine, SNTNIDRT, discussed in Chapter 7.

   o TMOFFSET - TIME OFFSET applied to the data in the file.
     The user can associate a TIME OFFSET with each unique
     NETWRKID/SYSID combination.  This offset is used to
     adjust data times when data from multiple time zones is
     brought together in the CA MICS database. To determine
     the original time at which the data was recorded,
     subtract TMOFFSET from the value.  TIME OFFSET is
     assigned in the SNTOPS member of prefix.MICS.PARMS,
     discussed in Chapter 7.

4. The following data elements lose significance after
   summarization has been performed.  These data elements
   should be referenced only when the last observed value in
   a summarization interval is significant.

   TCPRPORT - Remote Port Number (Data Connection)
   TCPLPORT - Local Port Number (Data Connection)
   TCPRADDR - Remote IP Address (Data Connection)
   TCPLADDR - Local IP Address (Data Connection)
   TCPSTACK - TCP/IP Stack Name
   TCPSOCID - TCP Socket Resource ID
   TCPSOCNM - TCP Socket Resource Name
   TCPVRRL  - z/OS CS TCP/IP Version/Rel.
   TCPUID   - User ID
   FCFDFMT  - Data Format
   FCFMODE  - Transfer Mode
   FCFDSTYP - Dataset Type
   FTPRPORC - Remote Port Number (Control Conn.)
   FTPLPORC - Local Port Number (Control Conn.)
   FTPRADRC - Remote IP Address (Control Conn.)
   FTPLADRC - Local IP Address (Control Conn.)
   FTPFSCS  - Cipher Specification for AT-TLS
   FTPFSPBS - Negotiated Protection Buffer Size
   FTPFSCP  - Control Connection Protection Level
   FTPFSDP  - Data Connection Protection Level

Retrieval Example

Chart prime shift FTP Server activity for sysid PROD.  Use
yesterday's data.

   DATA SELECTED (KEEP=SYSID DAY ZONE HOUR FCFBYTEI FCFBYTEO)
   ;
   SET &PTCPD..TCPFCF01;
   IF SYSID = 'PROD';
   IF 9 GE HOUR LE 17; /* SELECT PRIME SHIFT */

   PROC CHART DATA=SELECTED;
        VBAR HOUR / SUMVAR=FCFBYTES
        DISCRETE;
   TITLE 'DAYS TCPFCF01, PRIME SHIFT IN BYTE COUNT ';
   RUN;
