Hello everybody,
I need some help here to create a script to parse a log file. Here is a sample of the log file :

Hello,
i would like to parse Unix log files and i would like to use a Unix syslog analyzer.
I'm going to use Eucalyptus and i would like to parse its log files.
Is there any open source/free syslog parser??
Thanks, in advance! (2 Replies)
Hi,
I have a really simple question...I think. I want to be able to parse two or more files into one by reading the first record from each file into new file then go back to the first file and start reading the second record in from each file into new file and so on. I am new to using awk and am... (5 Replies)
Hello All,
Below is the excerpt from my Informatica log file which has 4 blocks of lines (starting with WRITER_1_*_1). Like these my log file will have multiple blocks of same pattern.

I am trying to parse the audit log to find a particular date that associated with a user record. The Date and the context of the record that I need to extract from the audit.log are 11-07-2015, the username and the activity he or she performed that day.
Here is my code:

bup-margin
bup-margin(1) General Commands Manual bup-margin(1)NAME
bup-margin - figure out your deduplication safety margin
SYNOPSIS
bup margin [options...]
DESCRIPTION
bup margin iterates through all objects in your bup repository, calculating the largest number of prefix bits shared between any two
entries. This number, n, identifies the longest subset of SHA-1 you could use and still encounter a collision between your object ids.
For example, one system that was tested had a collection of 11 million objects (70 GB), and bup margin returned 45. That means a 46-bit
hash would be sufficient to avoid all collisions among that set of objects; each object in that repository could be uniquely identified by
its first 46 bits.
The number of bits needed seems to increase by about 1 or 2 for every doubling of the number of objects. Since SHA-1 hashes have 160 bits,
that leaves 115 bits of margin. Of course, because SHA-1 hashes are essentially random, it's theoretically possible to use many more bits
with far fewer objects.
If you're paranoid about the possibility of SHA-1 collisions, you can monitor your repository by running bup margin occasionally to see if
you're getting dangerously close to 160 bits.
OPTIONS --predict
Guess the offset into each index file where a particular object will appear, and report the maximum deviation of the correct answer
from the guess. This is potentially useful for tuning an interpolation search algorithm.
--ignore-midx
don't use .midx files, use only .idx files. This is only really useful when used with --predict.
EXAMPLE
$ bup margin
Reading indexes: 100.00% (1612581/1612581), done.
40
40 matching prefix bits
1.94 bits per doubling
120 bits (61.86 doublings) remaining
4.19338e+18 times larger is possible
Everyone on earth could have 625878182 data sets
like yours, all in one repository, and we would
expect 1 object collision.
$ bup margin --predict
PackIdxList: using 1 index.
Reading indexes: 100.00% (1612581/1612581), done.
915 of 1612581 (0.057%)
