  • 解决rsyslog 断电或者被kill 重发问题

    $InputFilePersistStateInterval 1
    
    Specifies how often the state file shall be written when processing the input file. The default value is 0, which means a new state file is only written when the monitored files is being closed 
    
    (end of rsyslogd execution). Any other value n means that the state file is written every time n file lines have been processed. This setting can be used to guard against message duplication due to 
    
    fatal errors (like power fail). Note that this setting affects imfile performance, especially when set to a low value. Frequently writing the state file is very time consuming.

    2222222222222
    You have new mail in /var/spool/mail/root
    
    
    rsyslog 接收端:
    zjtest7-frontend:/data/scan# cat scan.2016-10-10 
     dadadatest
     1111111111111
     2222222222222
    zjtest7-frontend:/data/scan# cat scan.2016-10-10 
     dadadatest
     1111111111111
     2222222222222
     dadadatest
     dadadatest
     1111111111111
     2222222222222
    
    
    看到当kill后,会重发
    
    
    
    
    解决:
    input(type="imfile"
    File="/var/log/nginx/scan.log"
    Tag="uat-scan"
    Severity="info"
    PersistStateInterval="1"
    Facility="local5")
