Logstash parsing progress bar -

-

i'm newbie logstash , i'm using parsing 500mb of logfiles in particular directory, when i'm start logstash doen't show progress bar how % has completed parsing log file. there way see progress of log parsing done?

no, logstash has no built-in progress bar feature. of time wouldn't make sense since logstash meant process ever growing logs continuously, , there isn't "done".

what correlate contents of sincedb file file size of corresponding file. sincedb file logstash stores current offset in file. exact description of file format found in file input's documentation, have care first , last columns. first column inode number, can found in ls -li output file, , last column current offset. example:

393309 0 64773 437

here, logstash @ offset 437 file inode 393309.

the join command can used join file ls -li output (where file's inode number in first column):

$ join /var/lib/logstash/.sincedb_f5fdf6ea0ea92860c6a6b2b354bfcbbc <(ls -li /var/log/syslog) 393309 0 64773 437 -rw-r----- 1 root adm 437 oct 15 12:47 /var/log/syslog

finally, awk can used clean output , produce percent-completed number:

$ join /var/lib/logstash/.sincedb_f5fdf6ea0ea92860c6a6b2b354bfcbbc <(ls -li /var/log/syslog) | awk '{ printf "%-30s%.1f%\n", $13, 100 * $4 / $9 }' /var/log/syslog               100.0%

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
