If a customer purchases 100 NXLog Enterprise licenses and needs more six months later, do they place an order for the additional licenses separately or increase the original order? Are they able to deploy and then true-up, or do they need a unique key for each before deploying?

Hi team, 

i have converted auit messages in multiline to singleline using multiline parser. problem is two spaces are added instead of one space after semicolon.

message1;

message2;

single line: message1;. message2;

There is two space first simicolon and message2 instead of one how to remove extra space

I would like to ask, in some circumstances NXLogAgent on Windows, the agent cannot forwarding log to FortiSIEM (sometimes the agent was stopped by itself), I need to manual restart the agent to make the agent running again, in this situation is it abnormal or not?

Another question would be about the log format can be parsed by FortiSIEM or I need to custom parser to parse this log format or someone can provide this parser to me?

Best Regards, 

Good Afternoon.

I currently run a NX log solution that was setup by the vendor of our cloud IDS. I do know that we have a collection of logs coming from workstations to a central server and that server uploads the logs to the IDS. That being said, I have set up a gray log server on an Ubuntu box and I want to send my Windows DNS logs to that server so that I have a way to search DNS queries made by workstations should on of them become compromised. (via malware, ransomware, etc) I realize that there is already a config fiile for nx log that sends the event viewer logs so I am assuming that I would have to use that same file to have nx send dns logs to a different location (if that is even possible).   So my questions are, Is it possible to do that? If so, is the collection service that has to be stopped in order to edit the config file?

I would send these logs to the same online IDS service but we are already going over our quota every month and management doesn't see the need to upgrade our service. Therefore, I am left to figure out another way to stay on top of DNS threat hunting. 

Any input will be greatly appreciated.

Hi Folks,

I have a tcp output that has 3 hosts in sequence to send to graylog (failover), but I would like to "randomly" switch the ouputs to better distribute the load on the nodes. In my config example, 'graylog_1' will always receive all events. Is there a bultin solution for processor/output to send randomly to the multiple nodes?

Config example:

<Output out_graylog>
        Module om_tcp
        FlowControl False    
        Host 192.168.0.10:514 # graylog_1    
        Host 192.168.0.11:514 # graylog_2    
        Host 192.168.0.12:514 # graylog_3
</Output>

A viP/loadbalancer for graylog is not the solution I'm looking for, I want to understand the power of nxlog and its customization.

It would be nice if you eliminate scrolling with wrapping in this forum posts.

Hi the pronblem is that all works but I don´t receive any log.

Graylog version 4.3 in debian 11.  Sidecar graylog 1.2 and NXLOG 3.0 if my memory doesn´t fail.

What can i do?

Thanks and happy new year.

Guys, does anyone know where I can get information on average resource consumption by the Nxlog CE agent?

Thanks.

Hi All,

I have requirement to forward the windows logs to QRadar using NX . Below is my config file , I am unable to receive the log in my SIEM platform. I could encounter the error : ERROR failed to subscribe to msvistalog events,the channel was not found [error code: 15007]; The specified channel could not be found. Check channel configuration.

Hello,

I'm trying to forward the VPN logs of a Zyxel ATP700 to my SIEM (InsightIDR), the forwarding works fine, but I can't format them as indicated in this documentation

https://docs.rapid7.com/insightidr/rapid7-universal-vpn/

Can someone help me?

Thank you

Currently, I have GrayLog running as a docker image on an unraid server. Everything is working well. I also have a MS Windows lab environment that I want to forward logs into Graylog with the help of nxlog. I followed the instructions at: https://docs.nxlog.co/userguide/integrate/graylog.html and I don't have any errors, but I also don't have any data. Any ideas on how I can troubleshoot this to determine where my issue is?

Can anyone tell me for certain if this module is only included in the Enterprise version? If so, where does one buy the Enterprise Version and what is it's approximate cost? (USD)

Hello Team,

I am new to nxlog and i have a requirement to collect windows logs from 2003 servers and the agent version that i am using is “nxlog-ce-2.11.2190”

As per the documnet i have used im_mseventlog module, but still getting error and not able to pull the logs from 2003 servers. If some one please share me the config file for 2003 servers would be a great help 

below is the error that we are getting when starting the nxlog service.

I'm sending im_msvistalog messages to splunk via to_json().  I'm ending up with a field AccessList like:

AccessList: %%4423

which I assume is some kind of mapping of:

Access Request Information: Accesses: ReadAttributes

from the “Message” component.  Is that right?  If so, it's fairly obscure.  Is there some way to preserve “Accesses” as is?  What is “AccessList” trying to tell me?  Is there somewhere I can go to decode it?

Hi

Is it possible to install nxlog-ce-3.1.2319.msi on Windows 2008 R2?

TEST

Hi, 

Doing my first steps with NXlog.

I have managed to collect all “Security” windows event log and also managed to update the “Version” parameter to my own parameter - Just for a test purposes 

Now I need to perform 3 tasks 

1. Collect all “Security” windows event log - Done
2. Update the “Version” parameter from int to string - Done 
3. Update the “Hostname” parameter of specific event ID (for example EventID":4656) to “test”  - Please advice 

Thank you
