Hi, I just tried updating to 2.1.1 on my test instance and none of the incoming data is being written out to disk. It worked for me with 2.0.9. The problem is with the log_iw_size() parameter in my tcp source. Without it, the data is being logged to disk. My configuration file is below. Anything obviously amiss? Thanks, Joe -- # General Options options { sync(0); time_reopen(10); log_fifo_size(131072); long_hostnames(off); use_dns(yes); dns_cache(yes); use_fqdn(no); keep_hostname(yes); use_time_recvd(no); #log_msg_size(65536); log_msg_size(16384); stats_freq(180); #time_sleep(20); }; # Remote source source s_tcp { tcp(port(2000) log_iw_size(131072) log_fetch_limit(1024) max_connections(128)); }; # syslog-ng statistics source s_internal { internal(); }; destination d_file { file("/ita/syslog-messages" perm(0644)); }; destination d_stats { file("/ita/syslog-stats" perm(0644)); }; # Save stats separately log { source(s_internal); destination(d_stats); }; # Take all remote data and save it locally log { source(s_tcp); destination(d_file); flags(flow-control); };
