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

NAME
Smokeping::probes::skel - a skeleton for Smokeping Probes SYNOPSIS
*** Probes *** +skel forks = 5 offset = 50% step = 300 timeout = 15 # The following variables can be overridden in each target section pings = 5 # [...] *** Targets *** probe = skel # if this should be the default probe # [...] + mytarget # probe = skel # if the default probe is something else host = my.host pings = 5 DESCRIPTION
This is a non-functional module that is intended to act as a basis for creation of new probes. See the smokeping_extend document for more information. VARIABLES
Supported probe-specific variables: forks Run this many concurrent processes at maximum Example value: 5 Default value: 5 offset If you run many probes concurrently you may want to prevent them from hitting your network all at the same time. Using the probe- specific offset parameter you can change the point in time when each probe will be run. Offset is specified in % of total interval, or alternatively as 'random', and the offset from the 'General' section is used if nothing is specified here. Note that this does NOT influence the rrds itself, it is just a matter of when data acqusition is initiated. (This variable is only applicable if the variable 'concurrentprobes' is set in the 'General' section.) Example value: 50% step Duration of the base interval that this probe should use, if different from the one specified in the 'Database' section. Note that the step in the RRD files is fixed when they are originally generated, and if you change the step parameter afterwards, you'll have to delete the old RRD files or somehow convert them. (This variable is only applicable if the variable 'concurrentprobes' is set in the 'General' section.) Example value: 300 timeout How long a single 'ping' takes at maximum Example value: 15 Default value: 5 Supported target-specific variables: pings How many pings should be sent to each target, if different from the global value specified in the Database section. Note that the number of pings in the RRD files is fixed when they are originally generated, and if you change this parameter afterwards, you'll have to delete the old RRD files or somehow convert them. Example value: 5 AUTHORS
