No logs are collected from Fortinet units, but tcpdump on NXlog collector shows ingoing traffic coming from them
DS_534595 created
I have a setup using NXlog instances as collectors in a large number of security zones.
<Input in0>
Module im_tcp
Host XXX.XXX.XXX.XXX
</Input>
but for some reason this does not capture logs coming in on port 514 from Fortinet units; all other logs (from Windows and Linux servers) are received and processed just fine.
tcpdump -nvvA host [Fortinet unit IP]
shows log traffic coming in on the NIC from the given IP address.
What am I missing?

Sumo Logic Integration
A1 created
Hello!I am working on integrating NXLog with Sumo Logic. I followed the instructions on how to integrate with Sumo Logic in the setup documentation, but the logs are not being forwarded to Sumo Logic correctly, even though I receive the INFO successfully connected message. I believe it may be related to the token. My input is from an SSL connection (which is successfully connecting, I tested by diverting it to a file which I'm currently using as an intermediary until I figure this out). I have tried both options below. Module om_ssl Host syslog.collection.us1.sumologic.com Port 6514 CAFile %CERTDIR%\digicert_ca.crt Exec to_syslog_ietf(); Exec $raw_event =~ s/(\[.*])//g; \ $raw_event = replace($raw_event, \ '{', '[%SUMO_TOKEN%] {', 1); Module om_ssl Host syslog.collection.us1.sumologic.com Port 6514 CAFile %CERTDIR%\digicert_ca.crt Exec to_syslog_ietf(); Exec $raw_event =~ s/(\[NXLOG@14506.*?\])//g; \ $raw_event = replace($raw_event, \ '{', '[%SUMO_TOKEN%] {', 1);

NXLog and local mail server (postfix) issues
Konstantinos12 created
Hello everyone,New to NXlog, doing the trial now and on setup I have encountered an issue with setting up the mail server and stuck there… It is a ubuntu server (AWS EC2) with postfix installed that relays to google.Postfix works as when trying: echo "This is the body of the email" | mail -s "This is the subject line" user@ourdomain.com -r nxlog@ourdomain.com - I get the email, not an issue.When I go to the mail server config of the web UI I always get “Failed to send email”, also the same when I try to change the email or password. I see nothing in the mail log so it seems it is not even trying to send the email?The settings I try are:Host: 127.0.0.1Port: 25Sender: nxlog@ourdomain.comUsername/Password: (empty) - as we don't auth for the local interface, this is just a local relay Any advice on how to proceed since I'm stuck on this step… :( Thank you!

With pm_null being marked for deprecation, does anyone know what the suggested alternative would be for creating modular configurations that use multiple processors?e.ginput => p1 => p2 => outputWhere p1 and p2 are pm_null modules that contain execs to perform some transformation on the event?

exclude in im_file
HenkPuister created
I'm trying to configure an Exclude in im_file. I want to exclude logs with a date and number at the end of the filename. These files are already processed.Config:<Input PPS> Module im_file InputType multi_PPS File '%LOGDIR%\\*.log' # PPSPortaalManager_24-05-24_2.log Exclude '*_??-??-??_*.log' #. I've tried several notations, eg. double quotes instead of single, escaping the questionmarks. But none of them work. Searching for examples leads to 1 of 2 examples, which are very common examples, and none of them with wildcards.Using nxlog-ce-3.2.2329 .Has anyone a good, and working, example how to user Exclude in im_file?

OM_AZURE problem with CA
Brad created
I've been testing sending logs directly to Sentinel and am having a problem with NXLOG not liking the CA. The error is not one I'm finding a lot of online help with.“no certificate or crl found” appears in the the log file, repeatedly.Maybe an issue with the CA I'm pointing to? Is there a specific one for Azure Sentinel that I'm overlooking, and if so, where is that obtained?Thanks in advance.--B

im_msvistalog problems
cmarsura created
Hi,
seems there is a bug in im_msvistalog module in nxlog-ce-3.0.2272 for Windows.
After service has generated some output, stopping service sometimes give the message box "Broken pipe" and sometimes Nxlog write a malformed configcache.dat and following the start posts an ERROR failed to restore the saved position from bookmark xml (error:15008)"
Tested on Windows 2012 R2 and Windows 2019
<Output out>
Module om_file
File '%LOGDIR%\Output'
</Output>
<Input _im_eventlog>
Module im_msvistalog
SavePos TRUE
<QueryXML>
<QueryList>
<Query Id='1'>
<Select Path='Security'>*</Select>
</Query>
</QueryList>
</QueryXML>
# Query <QueryList>\
# <Query Id='0'>\

# </Query>\
# </QueryList>
</Input>
#<Output outNull>
# Module om_null
#</Output>
<Route RouteA>
Path _im_eventlog => out
</Route>
This issue make the module not worth to use because not saving the bookmark of the processed registry record, force it to generate same logs from start over each service restart.
Best.

Read a log with yesterdays date in the filename

I'm successfully using this config format with im_file to read logs with todays date in the filename:'\\server.domain\Logs\IN' + strftime(now(), "%y%m%d") + '.log'One of our services writes its log for the previous day at 3am on the next day. The filename has yesterdays date. What's the easiest/neatest/most efficient way of reading this log please?

im_tcp with InputType LineBased occasional truncated lines
sgcaveney created
Hi folks,We have an NXLog CE 3.2.2329 configuration using im_tcp with InputType LineBased, receiving blobs of JSON separated by newlines. The received data is passed to xm_perl and then relayed to an output.Under some conditions where there may be thousands of events per second, there is a very rare chance for one event to be truncated at the end yielding an incomplete json blob. We've verified that the input data coming from upstream is valid, fully formed JSON - the emitter encoding logs look OK. The preceeding and following lines are also received and parsed successfully. Has anybody else experienced similar behavior? At this point we suspect a bug in NXLog, considering that it occurs very infrequently (2-3 days between recurrences) and it only occurs during periods of relatively high load (normal load is ~150 events per second, load when issue occurs is ~800/s+)Relevant configuration: <Extension gelf>Module xm_gelf</Extension><Extension perl>Module xm_perlPerlCode /etc/nxlog/scripts/parse_mist.pl</Extension><Input mist_tcp>Module im_tcpHost 0.0.0.0Port 32768InputType LineBased<Exec>perl_call("parse_mist");if $nxlog_internal_drop_log drop();</Exec></Input><Output graylog>Module om_udpHost xPort 12201OutputType GELF</Output><Route graylog>Path mist_tcp => graylog</Route>

Is it possible to "reset the baseline" for the File Integrity module?
elazur@ecampus.com created
We currently have NXLog running on Windows 2019 with the file integrity module that monitors files in sub directories under a main directly. I.E. Say we have about 20 subdirectories for files under a directory called c:\code. If any file is changed/deleted/added under that directory, an alert message is sent out via the OM_UDP module to our siem. The problem I am looking to resolve, is that I will be copying over about 10 new directories with hundreds of files in each directory, and I don't want NXLog to generate hundreds of alerts because it found new files and directories. Is there a way to “reset” or “refresh” the baseline after the new files/folders are copied over so it will know those files should be there?
