How to 'improve' this script and also 'fix' the pattern matching part?
Hi all,
Below is my script. It is currently working but I want some advice on maybe improving it and need some help on the pattern matching
So basically I pass a log file and need to search for a block of text.
As you can see from the script, I search for the string "Fatal NI connect error 12170." and add 17 to it, that will be the block of text that am after. Then I print this block of text to a file and grep the 3 basic information that I am after which is Time, Client address and the WARNING. The WARNING line sometimes exist and sometimes it doesn't.
So far, running the script does most of what I wanted.
Sample output below:
Sometimes there are some 'malform' of some sort, the ones in RED above. And this is because sometimes the log contain something like below which I am not expecting it to have
Or something like below:
As a workaround to this malform, I am changing the script to check if the 7th line is not "^Time" then I am excluding this block of text. I can't find any way of matching a block of text starting from " Fatal NI connect error 12170" to "WARNING: inbound connection timed out (ORA-3136)". Unfortunately, sometimes it does not end with "WARNING: inbound connection timed out (ORA-3136)", instead the last line is "Client address: (ADDRESS=(PROTOCOL=tcp)(HOST=11.111.22.36)(PORT=64136))" and HOST and PORT changes.
Below is the script with the 'check' for the malform. The lines in RED.
Anyway, please advise if there is any better way of doing this the way it is now.
