Gelf in DHCP not showing messages

exabyte4 · July 17, 2018, 7:55am

Hi,

I’ve installed nxlog on a Windows server hosting a DHCP service.
I’m interested in viewing logs of DHCP events on Graylog.

I have set up the following config in nxlog:

define ROOT C:\Program Files (x86)\nxlog

Moduledir %ROOT%\modules
CacheDir %ROOT%\data
Pidfile %ROOT%\data\nxlog.pid
SpoolDir %ROOT%\data
LogFile %ROOT%\data\nxlog.log
Loglevel debug
Module xm_gelf Module im_file File "C:\Windows\Sysnative\dhcp\DhcpSrvLog-*.log" PollInterval 1 SavePos True ReadFromLast True Recursive False RenameCheck True Exec $FileName = file_name(); # Send file name with each message Module om_udp Module om_udp Host 192.168.205.242 Port 12201 OutputType GELF Exec $short_message = $raw_event; # Avoids truncation of the short_message field. Exec $gl2_source_collector = '5b4c8c06636311037456fe97'; Exec $Hostname = hostname_fqdn(); Path DHCP_IN => DHCP_OUT

I have added a GELF UDP input. I can see the network counters go up but no messages show.
Can you please help me?
The only thing I managed to find is indexing errors of the following:

{“type”:“mapper_parsing_exception”,“reason”:“failed to parse”,“caused_by”:{“type”:“illegal_argument_exception”,“reason”:“Can’t parse [index] value [not_analyzed] for field [SourceModuleType], expected [true] or [false]”}}=

Please format your post properly, so that line breaks are visible:
https://community.graylog.org/faq#format-markdown

Also, please post the complete logs of your Graylog node. What you’ve posted is usually just a warning when using Elasticsearch 5.x.

Thank you for your patience. Apologize for the clutter.

Here’s a more detailed post:

I am using Graylog 2.4.5.
I have a DHCP service installed on Windows Server 2012R2.
I’m intrested in seeing DHCP events on Graylog.

What I’ve done:
Installed nxlog with the following configuration:

define ROOT C:\Program Files (x86)\nxlog

Moduledir %ROOT%\modules 
CacheDir %ROOT%\data
Pidfile %ROOT%\data\nxlog.pid
SpoolDir %ROOT%\data
LogFile %ROOT%\data\nxlog.log
Loglevel debug

<Extension gelf> 
    Module xm_gelf
</Extension>

<Input 578f9dbc0ae2f10b1139b6a9>
    Module im_file
    File "C:\Windows\Sysnative\dhcp\DhcpSrvLog-*.log"
    PollInterval 1
    SavePos	True
    ReadFromLast True
    Recursive False
    RenameCheck True
    Exec $FileName = file_name(); # Send file name with each message
</Input>

<Output 578f97f40ae2f10b1139b093>
    Module om_udp
    Host 192.168.......
    Port ....
    OutputType  GELF
    Exec $short_message = $raw_event; # Avoids truncation of the short_message field.
    Exec $gl2_source_collector = '5b4c8c06636311037456fe97';
    Exec $Hostname = hostname_fqdn();
</Output>

I’ve installed the DHCP content pack from the Market.

Can you please intruct me on how to get the logs? Sorry for asking a trivial question.

Check http://docs.graylog.org/en/2.4/pages/configuration/file_location.html for the location of the log files in your particular installation of Graylog.

Karlis · July 17, 2018, 8:34am

This was in Your first post, a snippet from route section, I believe. Are You sure this is OK? Where are DHCP_IN and DHCP_OUT module names defined?

exabyte4 · July 17, 2018, 8:46am

Please disregard the first post, this was a template I have found.
My 2nd post shows current config.

I do need to spend more time on reading how this works exactly.

Ok
There is an example how to collect DHCP events using nxlog

exabyte4 · July 17, 2018, 9:51am

Thanks. This is weird. I see the counters going up. Meaning messages are received but I can’t see any in Graylog.

jochen · July 17, 2018, 9:57am

Try rotating the active write index (System / Indices / Index Set / Maintenance).

http://docs.graylog.org/en/2.4/pages/configuration/index_model.html

exabyte4 · July 17, 2018, 9:59am

Brilliant!!!
Works!

Now I have to learn how to better parse the messages but I will work on that.

You saved me. :]

exabyte4 · July 17, 2018, 10:01am

One quick question though - Once enabled, I get a warning:

Elasticsearch cluster is yellow. Shards: 8 active, 0 initializing, 0 relocating, 4 unassigned

Is there any way I can solve this quickly?

jochen · July 17, 2018, 10:11am

How many Elasticsearch nodes are you running?
If you’re only running a single Elasticsearch node, you have to disable shard replicas.

http://docs.graylog.org/en/2.4/pages/configuration/index_model.html#index-set-configuration

exabyte4 · July 17, 2018, 10:19am

I only have one node. Can I disable by changing the following (from 4) in the graylog.conf file?
elasticsearch_shards = 0

jochen · July 17, 2018, 10:21am

No. Read the documentation section I’ve linked to.

exabyte4 · July 17, 2018, 10:28am

Thank you. Now it’s all green.
