Hello, I was actually having that problem just few days back and my issue was related to DNS, if you DNS infrastructure is solid then I would not have any idea. I just thought it could help to eliminate that out. regards, Moitshepi On 12 August 2014 16:53, Simão Mata <simao.mata@wimdu.com> wrote:
Hello,
Our syslog-ng clients are losing their connection to our central log server every few minutes.
In the client I have the following log:
2014-08-12T15:44:02+00:00 wimdu-app07 syslog.notice syslog-ng[14032]: Syslog connection broken; fd='10', server='AF_INET(<our ip>:514)', time_reopen='1' 2014-08-12T15:44:03+00:00 wimdu-app07 syslog.notice syslog-ng[14032]: Syslog connection established; fd='10', server='AF_INET(<our ip>:514)', local='AF_INET(0.0.0.0:0)'
I am using the following configuration on the clients:
destination d_net_wimdu { syslog(<our ip> transport("tcp") port(514) log-fifo-size(2048)); };
log { source(s_src); source(s_net); destination(d_net_wimdu); };
And on the server:
source s_net { syslog(ip(0.0.0.0) transport("tcp") max-connections(300) log-iw-size(3300) so_rcvbuf(8000000000) port(514)); };
log { source(s_net); destination(d_file_w); };
destination d_prog_logparser { program("< logparser_bin >" template(t_w_filetemplate) log_fifo_size(90000000) flags(no-multi-line)); };
log { source(s_net); destination(d_prog_logparser); flags(flow-control); };
Any idea how I can even debug this?
Thank you
