Syslogd listens on UDP port 514, the syslog port. Syslogging enables you to gain information about LocalDirector traffic and performance, analyze logs for suspicious activity, and troubleshoot problems. Syslogd can run on a number of operating system platforms. Syslogd is installed when you install UNIX, but you have to configure it. Syslogd usually is not native to Windows-based systems, but syslogd software is available for Windows NT. Actual meanings of LocalDirector syslog messages are in the LocalDirector documentation. Before You Begin Conventions Refer to Cisco Technical Tips Conventions for more information on document conventions. Prerequisites There are no specific prerequisites for this document. Components Used The information in this document is based on Cisco LocalDirector Software. How Syslog Works All syslog messages have a logging facility and a level. The logging facility can be thought of as where and the level can be thought of as what. Logging Facility The single syslog daemon (syslogd) can be thought of as having multiple pipes. It uses the pipes to decide where to send incoming information based on the pipe on which the information arrives. In this analogy, the

How is this connection made? Where/when is this done? I mean if I http://www.cisco.com/c/en/us/support/docs/application-networking-services/localdirector-400-series/3995-setup-ld-syslog-3995.html use local5 or local6 instead, this won't work, so there has to be something special about local7. I just can't figure it out.I scoured the web, but wasn't able to find a precise answer.Thanks.M.

In the case of the boot log, fedora the operating system sets this tag to local7 before it send the log message to syslog. I'm not familiar enough with fedora to know how easily it is to change that, but I'm guessing it would be quite difficult. Now, most other applications also make use of syslog, and they all apply a tag to the message. That tag is intended to help you sort out the messages later, so that you can have a line like:local7.* /var/log/boot.logWithout it, all of the logs would be dumped together. The .* after the local7 actually means to accept any message with a facility set to local7 and any severity. The severity is another way of coding messages. They are the debug, info, critical, emerg, etc. flags that can be used to slice the messages up another way.I hope that helps some!

reports and analyzes them. Each message is labeled with a facility code, indicating the software type generating the message, and assigned a severity label. Computer system designers may use syslog for system management and security auditing https://en.wikipedia.org/wiki/Syslog as well as general informational, analysis, and debugging messages. A wide variety of devices, such as printers, routers, and message receivers across many platforms use the syslog standard. This permits the consolidation of logging data from https://forums.freenas.org/index.php?threads/log-messages-need-help.5867/ different types of systems in a central repository. Implementations of syslog exist for many operating systems. Contents 1 History 2 Syslog message components 2.1 Facility 2.2 Severity level 2.3 Message 3 Logger 4 Network protocol 5 Limitations 6 Outlook 7 Internet standard documents 8 See also 9 References 10 External links History[edit] Syslog was developed in the 1980s by Eric Allman as part of the Sendmail project. It was readily adopted by other applications and has since become the standard logging solution on Unix-like systems. A variety of implementations also exist on other operating systems and it is commonly found in network devices, such as routers. Syslog originally functioned as a de facto standard, without any authoritative published specification, and many implementations existed, some of which were incompatible. The Internet Engineering Task Force documented the status quo in RFC 3164. It was standardized by RFC 5424.[1] Various companies have attempted to claim patents for syslog implementations.[2][3] This had little effect on the use and standardization of the protocol.[citation needed] Syslog message components[edit] The information provided by the originator of a syslog message includes the facility code and the severity level. The syslog software adds information to the information header before passing the entry to the syslog receiver. Such components include an originator process ID, a timestamp, and the hostname or IP address of the device. Facility[edit] A facility code is used to specify the type of program that is logging the message. Messages with different facilities may be handled differently.[4] The list of facilities available[5] is defined by RFC 3164: Facility code Keyword Description 0 kern kernel messages 1 user user-level messages 2 mail mail system 3 daemon system daemons 4 auth security/authorization messages 5 syslog messages generated internally by syslogd 6 lpr line printer subsystem 7 news network news subsystem 8 uucp UUCP subsystem 9 clock daemon 10 authpriv security/authorization messages 11 ftp FTP daemon 12 - NTP subsystem 13 -
Received: 0 Trophy Points: 1 I am a former Nexenta user and decided to try FreeNAS. I am running FreeNAS-8.0.3-RELEASE-p1-x64 (9591). My NAS appears to be working correctly. No errors I can detect in stored files, and no indication of a problem from the GUI. My concern is why these errors are being produced. I have read similar posts that have suggested ignoring them but want to make sure I am doing the right thing. The GUI Interface (Alert button) reports no errors with ZFS. This is a production environment. Any help is greatly appreciated! 02-06-2012 19:15:40 Local7.Warning 192.168.118.112 Feb 6 19:15:43 istgt[6254]: istgt_lu.c:2798:luworker: ***WARNING*** LU1: lu_disk_queue_start() aborted 02-06-2012 19:15:40 Local7.Warning 192.168.118.112 Feb 6 19:15:43 istgt[6254]: istgt_lu_disk.c:5137:istgt_lu_disk_queue_start: ***WARNING*** transfer abort CmdSN=14375095 02-06-2012 19:15:40 Local7.Error 192.168.118.112 Feb 6 19:15:43 istgt[6254]: istgt_iscsi.c:5380:worker: ***ERROR*** iscsi_task_transfer_out() failed on iqn.2011-03.local.freenas:target,t,0x0001(iqn.1998-01.com.vmware:vm4-1e64b233,i,0x00023d000001) 02-06-2012 19:15:40 Local7.Error 192.168.118.112 Feb 6 19:15:43 istgt[6254]: istgt_iscsi.c:4334:istgt_iscsi_transfer_out: ***ERROR*** iscsi_read_pdu() failed, r2t_sent=1 02-06-2012 19:07:35 Local7.Warning 192.168.118.112 Feb 6 19:07:38 istgt[6254]: istgt_lu.c:2798:luworker: ***WARNING*** LU1: lu_disk_queue_start() aborted 02-06-2012 19:07:35 Local7.Warning 192.168.118.112 Feb 6 19:07:38 istgt[6254]: istgt_lu_disk.c:5137:istgt_lu_disk_queue_start: ***WARNING*** transfer abort CmdSN=14270352 02-06-2012 19:07:35 Local7.Error 192.168.118.112 Feb 6 19:07:38 istgt[6254]: istgt_iscsi.c:5380:worker: ***ERROR*** iscsi_task_transfer_out() failed on iqn.2011-03.local.freenas:target,t,0x0001(iqn.1998-01.com.vmware:vm4-1e64b233,i,0x00023d000001) 02-06-2012 19:07:35 Local7.Error 192.168.118.112 Feb 6 19:07:38 istgt[6254]: istgt_iscsi.c:4334:istgt_iscsi_transfer_out: ***ERROR*** iscsi_read_pdu() failed, r2t_sent=1 02-06-2012 19:07:05 Local7.Warning 192.168.118.112 Feb 6 19:07:08 istgt[6254]: istgt_lu.c:2798:luworker: ***WARNING*** LU1: lu_disk_queue_start() aborted 02-06-2012 19:07:05 Local7.Warning 192.168
