Hello, I have porblem with install nxlog-ce-2.10.2150.msi at a domain controler on windoes server 2012R2 , When I try to install program, I get that error "Installation directory must be a local hard driver". But I chosed local path "C:\Program Files (x86)\nxlog". I tried to change path to another local paths C:\ and C:\user_name.I all time get the same error. Someone know what I can do at this error?

Hello

NxLog CE 2.10.2150 is installed on two Windows Server 2019 Standard (version 1809) But every X minutes, the service crash and cause PRODUCTION issues. Here the Event Viewer Report :

Hi support,

1. We are trying to send logs from a server with NXLog agent installed to SIEM, with SSL/TLS (encrypted traffic) Would it be possible to only use ONE certificate for each agent?

2. For NXLog manager and the agents is it possible to use only ONE CA for One agent?

I do not see an install file for Ubuntu 20.04. Will one be made available when NXLog 2.11 is released?

Thanks in advance.

Is Anyone using NXLog to send Windows Events to Azure's Log Analytics, replacing Microsoft's OMS\MMA agent? The MS MMA agent is very limited on its outbound filtering, so NXLog is being considered. If someone is successful doing this, a example of the config file would be awesome. Thanks.

Hello,

I configured my conf file (comm. edition) with a query for certain event id's. The output works, however, is there a way to prevent every event from creating it's own log file? For instance, create 1 large file for the date vs having 200k+ logfiles daily.

I have just purchased the Enterprise Edition NX Log software as well as BH Support.

Can someone advise how I can get the products added to my subscription as well as access to the software downloads and support portal? Alternatively, if a vendor support contact can contact me directly that would be great.

Thanks

Hello everyone, I'm new to _NXLOG_ and I'm trying to understand how event creation and forwarding work. I have a question about the parse_json() function or maybe the to_syslog_ietf() function, I'm not sure. Is it possible to use `parse_json($Message)` then `to_syslog_ietf()` to forward `$Message` without all the fields obtained with parse_json included in the forwarded syslog event? Here are more explanations: - I receive a syslog event and use `parse_syslog_ietf()` - I get `$Message` which is json formated, so I use `parse_json($Message)` - As I want to forward a specific field (let's say _MsgToForward_) I define `$Message = $MsgToForward` - Then use `to_syslog_ietf` to forward it through syslog. In the forwarded event everything is ok, except that all the fields in the json (the original $Message field) are included in the forwarded message. But I don't understand why because if I put a `log_info($raw_event)` after the parse_syslog and after the parse_json, $raw_event has not changed. So is it to_parse-ietf() function which includes all the fields available? Can we avoid that? For instance the original event is: ``` 2020-12-29 03:05:19 INFO 1 2020-12-29T03:05:19.692869 admin-PC send-logs 3556 send-logs.exe - {"user":"NT AUTHORITY\\SYSTEM","name":"main","programSource":"send-logs","msgToForward":"Send-logs started"}; ``` Then the forwarded message: ``` 2020-12-29 03:05:19 INFO 1 2020-12-29T03:05:19.692869 admin-PC send-logs 3556 send-logs.exe [NXLOG@14506 MessageSourceAddress="127.0.0.1" EventReceivedTime="2020-12-29 03:05:19" SourceModuleName="inSyslog" SourceModuleType="im_udp" user="NT AUTHORITY\\SYSTEM" name="main" programSource="send-logs" msgToForward="Send-logs started"] Send-logs started ``` We can see the fields available in the json in the first event (user, name, programSource and msgToForward) are added in the second event. But there are useless here, so I'm trying to have this result : ``` 2020-12-29 03:05:19 INFO 1 2020-12-29T03:05:19.692869 admin-PC send-logs 3556 send-logs.exe [NXLOG@14506 MessageSourceAddress="127.0.0.1" EventReceivedTime="2020-12-29 03:05:19" SourceModuleName="inSyslog" SourceModuleType="im_udp"] Send-logs started ``` Is there a way to avoid parse_json or to_syslog_ietf to add these fields? (The number of fields and their names are not always the same.) Or should I just not use parse_json and use `regexp` instead to get the value of MsgToForward? My configuration if needed. ``` Module im_udp Host 127.0.0.1 Port 514 Module om_udp Host 127.0.0.1 Port 1514 Exec parse_syslog_ietf(); parse_json($Message); $Message = $MsgToForward; to_syslog_ietf(); Path inSyslog => outSyslog2 ``` Any help is welcomed. Thank you :) Whok.

HI Everyone,

I'm evaluating various Log centralization / log analysis tools for our enterprise. I've been looking into graylog for some time and have gotten to the point where I'm comfortable in it. I just started to look into NXLOG and I'm wondering which offering to choose.

From what I can see, NXLog is more capable than graylog as far as log collection goes.

Can someone help me understand this better? I see a lot of setups using BOTH, and I'm not really sure I want to use two systems --- we're not all that complex here to warrant that kind of setup.

Thank you!!!

How can I protect passwords that are stored in the nxlog config to access different systems. I am using the sql connector with a local sql account and it requires the username and password to be inputed into the config.

Do we have NXLog modules to process Citrix Access Gateway & Citrix NetScaler logs?

I am looking to output syslog logs from Dell Firewall into a local directory on my windows box and I am getting error message as below:

===
2020-12-11 07:01:21 WARNING not starting unused module syslogs

2020-12-11 07:01:21 ERROR failed to open tmp/output; The system cannot find the path specified.
=====

I do not understand where i can reference the "tmp/output" within the "C:\Program Files (x86)\nxlog\*" or how i can point the output file to another directory.

This is a windows box and i will like the files to be written to a folder path under C directory.

Can anyone help?

I would like to forward Windows Security Events into Azure's Log Analytics using NXLog instead of the Microsoft Monitoring Agent (MMA). Does anyone been able to do this? If so, would you care to share your config file setup?

Hi,

I'm currently using nxlog to forward RADIUS messages via syslog to my firewall. However, it has recently started complaining that the packets are too big, and so fragmentation is occurring which it doesn't like.

The temporary fix was to force the packets to cut at 1450 bytes, and this is my current config:

Panic Soft #NoFreeOnExit TRUE

# Check the size of our log file hourly, rotate if larger than 5MB

    Exec    if (file_exists('%LOGFILE%') and \
               (file_size('%LOGFILE%') >= 5M)) \
                file_cycle('%LOGFILE%', 8);
</Schedule>

    Exec    if file_exists('%LOGFILE%') file_cycle('%LOGFILE%', 8);
</Schedule>

</Extension>

$raw_event = substr($raw_event, 0, 1450);

</Exec>

</Input>

<Route 1> Path NPS => Firewall </Route>

<Route 2> Path NPS => SyslogServer </Route>

However, I'd prefer a neater solution, rather than just chopping the end off the packet. The only parts of the packet I'm interested in forwarding are:

Event Regex: <Acct-Status-Type\sdata_type="0">1</Acct-Status-Type>{1} Username Regex: <User-Name\sdata_type="1">([a-zA-Z0-9\._-]+)</User-Name> Address Regex: <Framed-IP-Address\sdata_type="3">([0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3})</Framed-IP-Address>

Is there a way to extract just those bits and parse that to the output?

Apologies if it's obvious, but I don't really understand how nxlog works! Give me powershell and I'm happy....

Thanks, Stephen

Hi,

i'm forwarding windows event to SIEM with nxlog i'm trying to send to SIEM the username of logged user (the user of event), without success it's possible to send username ?

thanks you

Hi All,

I'm trying solution to forward windows evento log to centralized server (Adiscon Loganalyzer, if you know free alternative please help me)

it's possible to convert raw data or filter data in "messages" to set it in respective fields?

For example, in SIEM (loganalyzer), i have two views (syslog and eventlog) syslog view is all ok

eventlog view has blank field :

Eventlog Type Event Source Event ID Event User

It's possible to filter message and write it to respective blank fields?

i have this basic nxlog.conf configuration

<Extension _syslog> Module xm_syslog </Extension>

<Input eventlog> Module im_msvistalog </Input>

<Output out> Module om_tcp Host 10.0.2.50 Port 514 Exec to_syslog_bsd(); </Output>

<Route eventlog_to_out> Path eventlog => out </Route>

Hi! We have some logs that we would like for NXLog to monitor. The logs are located in a folder where lots of logs also reside. For that reason we don't wish to use a wildcard, because many of the logs we don't care to monitor. How can we in a single input module monitor three files, say file1, file2, and file3? The information found [here](https://nxlog.co/documentation/nxlog-user-guide/im_file.html#im_file_config) indicates that you can use multiple `File` directives but when I tried it didn't work. Example: ``` Module im_file File "/var/log/file1.log" File "/var/log/file2.log" File "/var/log/file3.log" $logtime = strptime($raw_event, '%Y-%m-%d %H:%M:%S'); $timestamp = strftime($logtime, '%s'); $server = hostname_fqdn(); if $raw_event =~ /\[INFO\]/ $log_type = 'INFO'; if $raw_event =~ /\[WARNING\]/ $log_type = 'WARNING'; if $raw_event =~ /\[ERROR\]/ $log_type = 'ERROR'; ``` Do I need three different input modules or can I use just one? Thanks in advance!

hi guys,

Does anyone knows where to find the nxlog-5.1.6303_rpm_x86_64.rpm i am planning to install it on the oracle linux 7 and the epel of oracle linux 7 does not have the rpm for the nxlog.

any help is greatly appreciated.

Hi,

I have found a number of items on collecting logs from CloudWatch, but none on forwarding events to CloudWatch? I think we would need those App Keys we generate etc.

Anyone have any information on this or better yet - a CloudWatch Forwarder Template.

My thanks, MG

Take for example event 4624, with output as JSON to kafka, there is a JSON field in im_msvistalog:

"Category":"Logon",
...
"Task":12544,

Now, looking at an event 4624 collected via im_wseventing, the JSON looks like this:

"Task":"Logon"

Note: Field Category is missing! As "Task" contains the category, in reality, the Task is missing here..

Please fix that for the WEC collector.

Best regards Theo
