Re: How to count the number of occurrences of a certain string in file

[tzhu]

Hi Mark,

This is the script I'm using currently:

import sys
TOTAL_DISCONNECTIONS = 0 
TOTAL_CONNECTIONS = 0 
flowFile = sys.stdin
if (flowFile != None):
    for line in flowFile:
        if "Lost connection to server" in line:
            TOTAL_DISCONNECTIONS += 1
        if "Established connection to server" in line:
             TOTAL_CONNECTIONS += 1
attrMap = {"TOTAL_DISCONNECTIONS":TOTAL_DISCONNECTIONS,
           "TOTAL_CONNECTIONS":TOTAL_CONNECTIONS}  
flowFile = session.putAllAttributes(flowFile, attrMap)



Does it make sense to you? The error message says "filereader" object is not
iterable. So what is in flowFile now? How should I access the content in
filwFile?

Thanks,

Tina
