"module file not found" when using file->file_size() or other file functions in Exec
hukel
I am trying to use the example in https://docs.nxlog.co/ce/current/index.html#om_file for file rotation on Windows (nxlog-ce-3.1.2319).I receive the following errorERROR Couldn't parse Exec block at xxx.conf:104; couldn't parse statement at line 107, character 29 in xxx.conf; module file not found
ERROR module 'testfile' has configuration errorsusing this configuration. The output works fine if I don't use the functions, so I assume om_file must be loading (by default?).<Output testfile>
Module om_file
File "E:/nxlog_output/active/nxlog-out.txt"
<Exec>
# Format output
to_json();
# Rotate file based on size, move to staging folder
if (file->file_size() > 10M)
{
$stagingFolder = 'E:/nxlog_output/staged/';
$newfile = $stagingFolder + 'data_' + strftime(now(), '%Y%m%d%H%M%S') + '.log';
file->rotate_to($newfile);
}
</Exec>
</Output>

How to collect RADIUS Accounting messages over UDP?
hukel
Is there a combination of inputs and extensions that can be used to collect RADIUS accounting messages via UDP listener?
We use Microsoft NPS today, but could benefit from the forking and advanced parsing of NXLog. We send RADIUS accounting messages from multiple network devices and the differences in data layout are bit too much for NPS.

Windows event logging
scotty
Forgive my ignorance but I'm looking to use NX Log to capture all windows events under System, Application and Security whether they be Audit, Info, error or critical. Am I correct in my assumption that with no filter's it should collect everything?
<Select Path='Application'></Select>
<Select Path='Security'></Select>
<Select Path='System'></Select>
or do I need to specify on single lines each severity level? for example:
<Select Path='Application'>[System/Level=4]</Select>
<Select Path='Application'>[System/Level=3]</Select>
<Select Path='Application'>[System/Level=2]</Select>
and so on?

NXLog Uninstallation Issues via string
j_shek
Hi guys,
We have NXLog CE 3.0.2272 installed on a server which was originally installed by another user manually. We have tried uninstalling it via the uninstall string MsiExec.exe /X {xxxxx} via ConnectWise which appeared to have uninstalled ok. Since then, we have installed a newer CE version 3.1.2319 however after installation the nxlog service is non-existent. We suspect the uninstallation via string may have broken this. Several attempts using the original installer to repair or uninstall/reboots does not fix this.
Is there a way we can start fresh to remove NXLog completely then install? Any help would be appreciated :)
TIA
Jordan

Issues with the nxlog agent when installed on Citrix MCS VDI machines.

Hellow everyone!
I have a scenario that uses Citrix MCS where I installed the agent on the master image that provides clone images that should go with the nxlog agent installed and running. But the agent goes up with some errors as below:

Memory leak in NXLog 5 (include latest v5.6.7727)
Roman_Andreev
Hello!
We have permanent memory leaks on Windows Event Collect server with any 5 version NXLog. If we install any 4 version - it work without memory leak, but very slowly - it's accumulating queue on single filter for windows events. How we can help to fix it in next release?

Log are not in the order
mcoussi
Hi,
I use NXLog to send log of an Oracle Database to Graylog.
When i send the log to a INPUT in Graylog, the logs in Graylog are not in the same order as the source logfile.
I have configured an output to send event in an other logfile and in the new log the event are ine the same order as the source logfile.
Configuration to the UDP Output Graylog where the event are not in the same order as the source logfile.
<Extension gelf>
Module xm_gelf
ShortMessageLength 200
</Extension>
<Input ora-database-rman>
Module im_file
File "/oracle/rman/logs/DATABASE_*.log"
</Input>
<Output ext-graylog>
Module om_udp
Host XX.XX.XX.XX
Port XXXXX
OutputType GELF_UDP
</Output>
<Route database-rman
Path ora-database-rman => ext-graylog
</Route>
Configuration to the om_file module loca where the event are in the same order as the source logfile.
<Input ora-database-rman>
Module im_file
File "/oracle/rman/logs/DATABASE_*.log"
Exec sleep(100);
</Input>
<Output fileout>
File 'tmp/output'
Module om_file
</Output>
<Route database-rman
Path ora-database-rman => fileout
</Route>
Do you have an idea how to get the event in the order to the OUTPUT TCP ?
Thanks for your help,

NXLog not picking up new files in watched directory
abajosh
Hello all,
I have an application that sends log files to a directory formatted at YYYY-MM-DD.log (year, month, day). I'm watching the directory with the following stanza in the configuration file, but it does not recognize when the date changes and a new file is created. A service restart gets it reading the new file.
The configuration is as follows:
<Input cvdupdate>
Module im_file
File "/var/log/cvdupdate/*.log"
</Input>
I'm running NXLog on a Ubuntu 18.04 system. The version is 3.0.2272.

Duplicates 4624 or other Event Viewer Log
IB_179669
Hi, I'm using NXLOG Community to transfer logs in and out, from Windows clients to a Linux server with an NXLOG agent for log collection.
The logs arrive correctly, the only thing is that for the event viewer (example) 4624, I see logs with the same time, even in milliseconds, but the message varies only for a few lines of the "message" field.
I wanted to avoid using the repeat module because I would create the same a log recording increasing the database.

Sajeshvv23
Hi,
i have below replace function for replacing "|0" to "Zero".
Exec $Message = replace($Message, "|0 ", "Zero");
now, i want to replace "|0" to "|15" with Zero.
do i need to add 15 more Exec replace function, or is there is any way to replace using single exec using regex?

jQuery vulnerability in nxlog-manager-5.5.5398
sgiliyal
Greetings!
I have a vulnerability in jQuery to be addressed in the nxlog manager v5 (5.5.5398).
This is related to XSS vulnerabilities from the version of jQuery installed (1.8.3, 1.9.2 ui) .
Will upgrading Manager to 5.6.5633 resolve the issue and update jQuery to 3.5.0+ ?
If not, please can you provide steps to update jQuery manually?
Thanks!

NXlog EE 5.6.7727 im_odcb module buggy when FreeTDS used on Debian11
ppum
Hi all,
I think there might be a bug in the im_odbc module in the Linux (Debian11) im_odbc module for NXLog 5.6.7727 EE when used with the FreeTDS driver (via unixODBC) - so for example if you try to connect to MS SQL or Sybase databases.
Although all the drivers etc. were configured correctly (it was basically a copy from a system where it used to work) and connecting to the databases via ISQL worked fine, the Agent wasn't able to fetch logs and produced following errors in the nxlog.log:
INFO [im_odbc|inputxy] im_odbc successfully connected to the database
WARNING [im_odbc|inputxy] im_odbc detected a disconnection, attempting to reconnect in 1200 seconds
ERROR [im_odbc|inputxy] SQLDescribeParam failed, IM001:2:0:[unixODBC][Driver Manager]Driver does not support this function (odbc error code: -1)
I've tested multiple FreeTDS driver versions with multiple compile options - but none of them worked.
Finally I figured to try a different NXLog version, so I downloaded the NXLog Agent EE 4.10.5000 for debian10 and it worked out of the box with the standard FreeTDS driver from the Debian11 repo (v1.2.3) and unixODBC (2.3.6).
So my conclusion is that there is a bug in the 5.6 EE NXLog Agent Version regarding the im_odbc module when used with FreeTDS (at least for Debian 11).
So while using 4.10 as a fallback is nice, it would be great to use the newer 5.x versions in the future.
