Regex to exclude certain error types from the log -

-

i relatively new need write regex exclude known error types log.

00:11:04 [0] 70-error: invalid index command: "/search.asp". 00:11:04 [0] 70-error: invalid index command: "/wingate-internal//boot.ini". 00:11:04 [0] 70-error: invalid index command: "/".

and exclude this: 

04:16:46 [8] 70-error: action failed - unencrypted communication not  allowed (10.40.88.11): "action=getstatus". 04:14:17 [7] 70-error: action failed - unencrypted communication not allowed (10.40.88.11): "action=getstatus".

i have other error types within same log fine reporting, example:

17:43:17.370 executerw: 957:error [2400] db matters - adddoctoworklist - dosqlcommand: error executing sql statement - cid ed83d1e0d

in other words, regex report on errors except 2 types mentioned above.

i tried creating regex doesn't seem work:

/(?:)(?:[^error\:\ action\ failed\ \-\ unencrypted\ communication\ is\ not\ allowed]*)(?:[^error\:\ invalid\ index\ command\:]*)/m

any appreciated.

how about:

^(?!.*error: invalid index command)(?!.*error: action failed - unencrypted communication not allowed)

explanation:

^                           : begining of string (?!                         : negative lookahead (asserts following not present in string     .*                      : 0 or more (*) character newline (.)     error: invalid index command   : literally )                           : end of lookahead (?!                         : negative lookahead (asserts following not present in string     .*                      : 0 or more (*) character newline (.)     error: action failed - unencrypted communication not allowed : literally )                           : end of lookahead

this regex matches lines not contain error: .........

in use in perl script:

#!/usr/bin/perl use modern::perl;  $re1 = qr/^(?!.*error: invalid index command)(?!.*error: action failed - unencrypted communication not allowed)/;  while(<data>) {     print if /$re1/; }  __data__ 17:43:17.370 executerw: 957:error [2400] db matters - adddoctoworklist - dosqlcommand: error executing sql statement - cid ed83d1e0d 00:11:04 [0] 70-error: invalid index command: "/search.asp". 17:43:17.370 executerw: 957:error [2400] db matters - adddoctoworklist - dosqlcommand: error executing sql statement - cid ed83d1e0d 00:11:04 [0] 70-error: invalid index command: "/wingate-internal//boot.ini". 17:43:17.370 executerw: 957:error [2400] db matters - adddoctoworklist - dosqlcommand: error executing sql statement - cid ed83d1e0d 00:11:04 [0] 70-error: invalid index command: "/". 17:43:17.370 executerw: 957:error [2400] db matters - adddoctoworklist - dosqlcommand: error executing sql statement - cid ed83d1e0d 04:16:46 [8] 70-error: action failed - unencrypted communication not allowed (10.40.88.11): "action=getstatus". 17:43:17.370 executerw: 957:error [2400] db matters - adddoctoworklist - dosqlcommand: error executing sql statement - cid ed83d1e0d 04:14:17 [7] 70-error: action failed - unencrypted communication not allowed (10.40.88.11): "action=getstatus". 17:43:17.370 executerw: 957:error [2400] db matters - adddoctoworklist - dosqlcommand: error executing sql statement - cid ed83d1e0d

output:

17:43:17.370 executerw: 957:error [2400] db matters - adddoctoworklist - dosqlcommand: error executing sql statement - cid ed83d1e0d 17:43:17.370 executerw: 957:error [2400] db matters - adddoctoworklist - dosqlcommand: error executing sql statement - cid ed83d1e0d 17:43:17.370 executerw: 957:error [2400] db matters - adddoctoworklist - dosqlcommand: error executing sql statement - cid ed83d1e0d 17:43:17.370 executerw: 957:error [2400] db matters - adddoctoworklist - dosqlcommand: error executing sql statement - cid ed83d1e0d 17:43:17.370 executerw: 957:error [2400] db matters - adddoctoworklist - dosqlcommand: error executing sql statement - cid ed83d1e0d 17:43:17.370 executerw: 957:error [2400] db matters - adddoctoworklist - dosqlcommand: error executing sql statement - cid ed83d1e0d
