Converting XML to syslog
Hi,
I'm looking at trying to convert an XML file from one of our filers containing this XML file below (top line is different to rest of the xml) into a syslog output:
`<Events xmlns="http://www.netapp.com/schemas/ONTAP/2007/AuditLog">
<Event><System><Provider Name="NetApp-Security-Auditing" Guid="{3CB2A168-FE19-4A4E-BDAD-DCF422F13473}"/><EventID>4656</EventID><EventName>Open Object</EventName><Version>101.3</Version><Source>CIFS</Source><Level>0</Level><Opcode>0</Opcode><Keywords>0x8020000000000000</Keywords><Result>Audit Success</Result><TimeCreated SystemTime="2017-12-15T10:34:51.979061000Z"/><Correlation/><Channel>Security</Channel><Computer>server</Computer><ComputerUUID>cf380853-6606-11e6-9638-00a098a5e1db/2fe0edc3-723f-11e7-ab83-00a098a627d4</ComputerUUID><Security/></System><EventData><Data Name="SubjectIP" IPVersion="4">192.168.0.24</Data><Data Name="SubjectUnix" Uid="65534" Gid="65534" Local="false"></Data><Data Name="SubjectUserSid">S-1-5-21-1997283580-3459341067-486214353-122727</Data><Data Name="SubjectUserIsLocal">false</Data><Data Name="SubjectDomainName">Domain</Data><Data Name="SubjectUserName">firstname.lastname</Data><Data Name="ObjectServer">Security</Data><Data Name="ObjectType">Directory</Data><Data Name="HandleID">000000000004cc;00;00000061;2a5f8706</Data><Data Name="ObjectName">(server);/share</Data><Data Name="AccessList">%%4416 %%4423 </Data><Data Name="AccessMask">81</Data><Data Name="DesiredAccess">Read Data; List Directory; Read Attributes; </Data><Data Name="Attributes"></Data></EventData></Event>`
Currently I have the following config but I'm not getting anything sent to the syslog server running on the same box (for testing purposes at present):
define ROOT C:\Program Files (x86)\nxlog
<Extension gelf>
Module xm_gelf
</Extension>
Moduledir %ROOT%\modules
CacheDir %ROOT%\data
Pidfile %ROOT%\data\nxlog.pid
SpoolDir %ROOT%\data
LogFile %ROOT%\data\nxlog.log
<Extension multiline>
Module xm_multiline
HeaderLine /^<event>/
EndLine /^</event>/
</Extension>
<Extension xmlparser>
Module xm_xml
</Extension>
<Extension json>
Module xm_json
</Extension>
<Input in>
Module im_file
File "C:\\audit.xml"
SavePos FALSE
ReadFromLast FALSE
InputType multiline
<Exec>
# Discard everything that doesn't seem to be an xml event
if $raw_event !~ /^<event>/ drop();
# Parse the xml event
parse_xml();
# Rewrite some fields
#$EventTime = parsedate($timestamp);
#delete($timestamp);
#delete($EventReceivedTime);
# Convert to JSON
to_json();
</Exec>
</Input>
<Output out>
Module om_udp
Host 192.168.0.12
Port 2548
</Output>
<Route 1>
Path in => out
</Route>
Can anyone point me at where I'm going wrong?
Thanks for your help.
The config with xm_multiline
will read XML when the tags are on separate lines like this:
<Event>
<Foo>foo</Foo>
<Bar>bar</Bar>
</Event>
In this case it looks like your events are in a single line.
Also looking at the data I see that this is XML extracted from the windows eventlog. You might want to consider using the im_msvistalog
module to read that directly. There is a File
directive for im_msvistalog
in the Enterprise Edition that lets you read .evtx
files directly that netapp creates.
