Hi All,

I am experiencing a weird problem with Syslog-NG 3.8.1 on Ubuntu 14.04

When syslog receives syslog messages from couple of specific nodes it saves it on a destination folder as per the config below:

source s_rohnet {

network(

transport("udp")

);

};

destination d_rohnet_switches {

file("/var/log/ROHNetwork/${YEAR}.${WEEK}/${HOST}.log" create-dirs(yes) dir-owner("rohadmin"));

};

The devices are NTP synchronised and the date output is correct on the Ubuntu server:

>date

Tue Nov 22 11:21:14 GMT 2016

Beside these the log folders created where the files gets stored are: /2015.51/192.168.33.8.log (it should be /2016.47/).

This is happening only for two nodes while all the rest seems to work fine.

I have captured some network traffic and the message received by syslog-ng on the network card seems also correct as per Wireshark output:

Syslog message: LOCAL6.NOTICE: NOV 22 10:31:23 192.168.33.8-1 CMDLOGGER[165319912]: cmd_logger_api.c(83) 13518 %% CLI:192.168.32.100:root:User logged in

This is a Dell switch and I am opening a case with them but I would like to know where else I should check for configuration errors.

Syslog config is exactly the one reported above.

Any idea of what I could check for further troubleshooting on the Syslog side?

Thanks,

Marco
