Inferring from lines 5 and 8, the division should be done by constant 2, not the line count per key. Under the assumption that field 8, embedded in field separators, is NOT matched anywhere else in the line, try
Code:
awk 'NR == FNR {SUM[$3]+=$7+$9; next} {sub (FS $8 FS, FS sprintf ("%06d", SUM[$3]/2) FS)}1' file file

Should the line count matter, try
Code:
awk 'NR == FNR {SUM[$3]+=$7+$9; CNT[$3]++; next} {sub (FS $8 FS, FS sprintf ("%06d", SUM[$3]/CNT[$3]) FS)}1' file file

TORRUS_RRDDIR2XML(8)						      torrus						      TORRUS_RRDDIR2XML(8)

NAME
rrddir2xml - Searches a directory for RRD files and generates Torrus XML configuration file. SYNOPSIS
torrus rrddir2xml --dir=DIR [options...] DESCRIPTION
rrddir2xml searches in a given directory for RRD files and creates Torrus XML configuration file suitable for browsing ofthose data files. With default options, it is usable for RRD files generated by Torrus' SNMP collector, where the file name starts with the host name, separated by underscore from interface name or other MIB specifics. With these defaults, it creates a subtree per each host name, and all RRD files belonging top that host name are sorted alphabetically in that subtree. OPTIONS
--dir=DIR Absolute path to the directory for searching. The directory may contain also non-RRD files. Only regular files are processed, and the symlinks are ignored. --recursive If specified, the directory will be searched recursively. All file names across all subdirectories must be unique. Symlinks to other directories are ignored. --filter=Regexp If the filter is specified, then rrddir2xml lists only those files and subdirectories whose names match the given regular expression. --out=FILE Output XML file name. If relative path given, the file is placed in /etc/torrus/xmlconfig. Default: rrddir.xml. --subtree=SUBTREE Top subtree path in the generted XML. Default is the top of the tree ("/"). --split=REGEXP Regular expression used for splitting the file name into parts to build the subtree hierarchy. Default is a sequence of underscores ("_+"). --levels=INTEGER Number of levels of hierarchy to build by splitting the file names. Default is 2 levels. --comment=TEXT Text to put as "comment" parameter to the top subtree. --holtwinters If specified, Holt-Winters prediciton boundaries and failures are displayed in the graphs. --verbose Prints extra diagnosics. --debug Prints debugging information.
