It appears that nxlog continually retries when trying to send a log. Is there a way to limit the amount of retries and continue on if it fails over x amount of times? My issue is this, if the body of the request is bad, I will get a 400 as a result. This means, I could get stuck trying to send a bad message over and over.

Is there a way to send multiple records in an http call? I'd like to send multiple rows of my log file via an http call.

There is a bug in NXLog Community Edition 2.10.2150, with module im_ssl regarding opening CA files. NXLog seems to create a file descriptor for the CA file each time a new connection is made. That is, NXLog opens the file again and again. If NXLog runs on Linux, this can quickly hit the OS limit of maximum number of files open. The following error is seen repeatedly once the OS limit of file descriptors is reached: ERROR SSL error, failed to load ca cert from '<path_to_file>', Too many open files Raising the OS limit is only a temporary solution: eventually, the next limit can be hit How can this bug be fixed?

Hi, I'm trying to parse a csv log file from my local and store it again in another location in my local. But I see it is not happening. The config has no errors. the destination file is same as source file with respect to file properties. Can you tell whether any specific check should be done? <Extension csv_parser1> Module xm_csv Fields date-time,client-ip,client-hostname,server-ip,server-hostname, source-context,connector-id,source,event-id,internal-message-id,message-id,recipient-address, recipient-status,total-bytes,recipient-count,related-recipient-address,reference,message-subject, sender-address,return-path,message-info,directionality,tenant-id, original-client-ip,original-server-ip,custom-data Delimiter , </Extension> Message Tracking log as input <Input messagetracking> Module im_file File '%BASEDIR%file.log' <Exec> if $raw_event =~ /^(\xEF\xBB\xBF)?(date-time,|#)/ drop(); else { csv_parser1->parse_csv(); $EventTime = parsedate(${date-time}); } </Exec> </Input> <Output msg> Module om_file File 'location\msg.log' </Output> <Route 1> Path messagetracking => msg </Route>

Can you explain what exactly happens in this block? I don't get a clear explanation of what "xEF\xBB\xBF" means in the below code and why it is having drop ()? . <Exec> if $raw_event =~ /^(\xEF\xBB\xBF)?(date-time,|#)/ drop(); else { csv_parser->parse_csv(); $EventTime = parsedate(${date-time}); } </Exec>

Hi, I would like to know the cost of enterprise edition. Also, I would like to know whether we could use the purchased nxlog EE package in more than one server to collect logs?

Hi, I'm using a CE where xm_w3c module is not available. So i'm getting below error: 2019-04-09 14:59:30 ERROR Failed to load module from C:\Program Files (x86)\nxlog\modules\extension\xm_w3c.dll, The specified module could not be found. ; The specified module could not be found. 2019-04-09 14:59:30 ERROR Invalid InputType 'w3c_parser' at C:\Program Files (x86)\nxlog\conf\nxlog.conf:94 Is there a way to overcome this error in CE by downloading the particular module ? Or should I try using the Enterprise edition?

Hi, Im actually having an issue with my nxlog server. We are trying to send antivirus log from a McAfee EPO to my NX. The problem we facing is that when we try a connection test from EPO to NXLOG we get this message on our Nxlog server. 2019-04-09 19:32:54 INFO SSL connection accepted from 10.28.26.214:59126 2019-04-09 19:32:54 ERROR SSL error, SSL_ERROR_SSL: retval -1, reason: peer did not return a certificate 2019-04-09 19:32:54 WARNING SSL connection closed from 10.28.26.214:59126 Can we receive the AV log without using the certificate ? Do you know a way to bypass this ?. The certificat have been created with OPENSSL with the help of one of your technicien and the certificat looks good... we have somme difficulty to understand why this operation fail. We have also put the certificat we create for NXLOG on our Antivirus server to let them communicate. Do you have any idea of what is the problem ? Your help is very appreciated gain. Greetings,

Is the scalability / performance of community vs enterprise edition any different? We tried the community edition for WEC/WEF and it appears to be dropping logs at 2000 eps. We're wondering if there are any configuration we should be aware of. Moreover, please provide sizing recommendations: > What eps can a single nxlog agent support for WEC/WEF collection? > How many VM's of what size (CPU cores and GB memory) should we plan for to support 50,000 eps?

Is there a way to run NxLOG in a "throttled" state during certain times of the day? For instance, process x number of logs per hour from 8-5

Hi. We are facing this problem that NXLog takes a lot of memory when using it to collect logs from PostgreSQL database. I tried to modify the polling interval in the config but it did not help.

Hello, I hope someone can help me. I need to pick application logs from a few MSSQL database tables. 3 of 4 works perfect -there are no issues getting the data, but one table is causing issues. Below you can see input I am using. As you can see, there is one column name with the Danish character, however, I am not sure if only this is causing trouble. The error I receive is: ERROR SQLExecDirect failed, 42000:2:102:[Microsoft][SQL Server Native Client 11.0][SQL Server]Incorrect syntax near 'Ą'.; 42000:3:319:[Microsoft][SQL Server Native Client 11.0][SQL Server]Incorrect syntax near the keyword 'with'. If this statement is a common table expression, an xmlnamespaces clause or a change tracking context clause, the previous statement must be terminated with a s (odbc error code: -1) However, If I remove this column from SELECT, another error occurs: ERROR id column not found or its type is unsupported. I received a similar error than I left some additional spaces in the query, but after that, I used notepad++ to make sure I don't leave any hidden characters. ========================================================= </Input> <Input odbc_besked> Module im_odbc ConnectionString Driver={SQL Server Native Client 11.0};Server=SERVERNAME\mssql2014,port;Database=database_name;Trusted_Connection=yes; SQL SELECT BeskedType, Oprettet, InternBeskedId, SvarPåInternBeskedId, Retning, BeskedArt, SoapBeskedId, BeskedId, HttpStatusCode, Fra, Til, Failover, EnvelopeStartTag, SoapHeaderElement, IndeholderSoapFault, Stack FROM table_name WITH (NOLOCK) WHERE InternBeskedId > ? </Input>

Hi, I am collecting events (im_msvistalog) from system 7001 and 7002 logon and logoff, I would like to know which field I use to catch the user who is logged on or off, because $UserID returns a SID. Thank you.

Hi, I'm trying to transfer two different csv files having different set of columns to a location. I'm trying to define them in one config file. I would like to know how we define the Extension module for this scenario since xm_csv is going to be the common one for the entire file. Is there any option to use more than one extension module with xm_csv specific to each file? Sample: Is this possible in one config file? Extension <Extension csv_parser> Module xm_csv Fields A,B,C,D Delimiter , </Extension> <Extension csv_parser> Module xm_csv Fields E,F,G Delimiter , </Extension>
