still problem with maximum estimated daily count
Hi,
I have modified the code as follows, however I cannot work out how to get the correct stats. In and out counts are correct but maximum/estimate should be 3 since there are 3 out at one time before they start to return.Smilie

any help appreciated... thanks

Code:
BEGIN { OT=0 # Time of previous measurement
MAX=1 # Max num of seconds between valid events
DAY=""; # Current day
CA=0 ; CB=0 ; CX=0 ; CD=0 # var to "hold" in or "out" A, C are one direction, B, X are the other dir
# Running total of bats leaving and entering
TOTALBATS=0;
# The highest TOTALBATS has ever been
MAXBATS=0;
# Length of the patterns
L=4
# Patterns to check against
# Block 1 unBlock 1 block 0 Unblock 0
#A[0]="1,1"; A[1]="1,0"; A[2]="0,1"; A[3]="0,0";
A[0]="1,1"; A[1]="1,0"; A[2]="0,1"; A[3]="0,0";
# Block 1 Block 0 unblock 1 Unblock 0
X[0]="1,1"; X[1]="0,1"; X[2]="1,0"; X[3]="0,0";
# Block 0 Unblock 0 Block 1 Unblock 1
B[0]="0,1"; B[1]="0,0"; B[2]="1,1"; B[3]="1,0";
# Block 0 block 1 unBlock 0 unblock 1
D[0]="0,1"; D[1]="1,1"; D[2]="0,0"; D[3]="1,0";
}
function print_daily(day,total,max,min,maxtime)
{
I=total; if(I<0) I=-I;
MX="no maximum"
if(maxtime > 0)
MX=sprintf("peak was at %s", strftime("%H:%M:%S",maxtime));
# printf("COUNT@%s COUNT %+d RET %d LEFT %d GUESS %d (%s)\n",
printf("Date @%s IN %+d OUT %d Max %d Estimate %d bats(%s)\n",
#day, total, max, -min, I, MX) > "/dev/stderr";
day, CA, CB, MAXBATS, I, MX) > "/dev/stderr";

# Reset daily counts
TOTALBATS=0; MAXBATS=0; MINBATS=0; MAXTIME=0;
MINTIME=0;  CA=0; CB=0;
}
{ # Calculate timestamp from date string
T=mktime($1 " " $2 " " $3 " " $5 " " $6 " " $7);
T+=(60*60*16); # Add sixteen hours
$1=strftime("%Y", T); # Put these back in the strings
$2=strftime("%m", T);
$3=strftime("%d", T);
$5=strftime("%H", T);
$6=strftime("%M", T);
$7=strftime("%S", T);
# When the year, month, and/or day changes, time to print daily counts
if((DAY != $1 "-" $2 "-" $3) && (DAY != ""))
print_daily(DAY,TOTALBATS,MAXBATS,MINBATS,MAXTIME);
DAY=$1 "-" $2 "-" $3;
if($8 == "pv") # Ignore anything but PV lines.
{
# If too much time has passed since the last event, start over.
if((T-OT) > MAX) # Blank the array
  for(N=0; N<(L-1); N++) C[N]="";
  else # Shift elements toward the front
  for(N=0; N<(L-1); N++) C[N]=C[N+1];
  OT=T # Set prev time to this one.
  C[L-1]=$9 "," $10; # Set the latest event in the array
  # Search for events in the array.
  FOUNDA=1; FOUNDB=1;
  FOUNDX=1; FOUNDD=1;
  for(N=0; N<L; N++)
  {
  if(A[N] != C[N]) FOUNDA=0;
  if(B[N] != C[N]) FOUNDB=0;
  if(X[N] != C[N]) FOUNDX=0;
  if(D[N] != C[N]) FOUNDD=0;
  }
  # Count the events and mark the hour they occurred in
  if(FOUNDA || FOUNDX)
  {
  # if(FOUNDX) CX++;
  # else
  CA++;
  printf("A@%s-%s-%s %s:%s:%s\n",$1,$2,$3,$5,$6,$7);
  AH[$5]++;
  TOTALBATS++;
  }
  if(FOUNDB || FOUNDD)
   {
 # if(FOUNDD) CD++;
 # else
 CB++;
printf("B@%s-%s-%s %s:%s:%s\n",$1,$2,$3,$5,$6,$7);
BH[$5]++;
TOTALBATS--;
}
# Update our maximum daily counts
if(MAXBATS < TOTALBATS)
{
MAXBATS=TOTALBATS;
MAXTIME=T;
}
#if(MINBATS > TOTALBATS)
#{
#MINBATS=TOTALBATS;
#MINTIME=T;
#}
}
}
END { # The final statistics will be printed to stderr, to easily
# seperate them from the event times printed to stdout.
# The last daily count
print_daily(DAY,TOTALBATS,MAXBATS,MINBATS,MAXTIME);
# Print the event counts
printf("A %2d\nB %2d\nX %2d\nD %2d\nT %2d\n", CA, CB, CX, CD, CA+CB+CX+CD) > "/dev/stderr";
# Print a list of hours from 1-23
STR="H";
for(N=1; N<=23; N++) STR=STR sprintf(" %2d", N);;
print STR > "/dev/stderr";
# Print hourly counts for event A
STR="A";
for(N=1; N<=23; N++)
STR=STR sprintf(" %2d", AH[sprintf("%02d", N)]);
print STR > "/dev/stderr";
# Hourly counts for event B
STR="B";
for(N=1; N<=23; N++)
STR=STR sprintf(" %2d", BH[sprintf("%02d",N)]);
    print STR > "/dev/stderr";
    }

the result I get is this:
Code:
Date @2011-07-19 IN +6 OUT 6 Max 1 Estimate 0 bats(peak was at 16:10:28)
A  0
B  0
X  0
D  0
T  0
H  1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
A  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  6  0  0  0  0  0  0  0
B  0  0  0  0  0  0  0  0  0  0  0  0  0  0  0  6  0  0  0  0  0  0  0

using this as input data:
