R80.10 Syslog Exporter

Via Check Point Support you get a Syslog exporter for SIEM applications for R80.10 Managment.

Which allows an easy and secure method for exporting CP logs over syslog. Exporting can be done in few standard protocols and formats.

Log Exporter supports:

  • Splunk
  • Arcsight
  • RSA
  • LogRhythm
  • QRadar
  • McAfee

Log Exporter is a multi-threaded daemon service, running on a log server. Each log that is written on the log server is read by the log exporter daemon, transformed into the desired format and mapping, and then sent to the end target.

 

Installation on R80.10 Jumbo Hotfix Take 56 or higher.

 

Syntax:

# cp_log_export add name <name> [domain-server <domain-server>] target-server <target-server> target-port <target-port> protocol <(udp|tcp)> [optional arguments]

 

Command Name

Command Description

add

Deploy a new Check Point logs exporter.

set

Updates an exporter's configuration.

delete

Removes an exporter.

show

Prints an exporter's current configuration.

status

Shows an exporter's overview status.

start

Starts an exporter process

stop

Stops an exporter process.

restart

Restarts an exporter process.

reexport

Resets the current position, and re-exports all logs per the configuration.

Please see this snapshot.

Also when i try to delete, it didn't allow me to delete it. Should i try to delete the EXPORTERDIR manually.

After deleting the EXPORTERDIR manually, will it create the EXPDIR again automatically.(After cpstart).

Hello,

Since the $EXPORTERDIR wasn't defined at the time of deployment, the exporter was deployed to /opt/CPrt-R80/log_indexer/targets/ (you can see the location in the show status output).

Now that the $EXPORTERDIR variable is defined it's looking for it (and trying to delete it) in the 'correct' location.

That's why I said you might have to manually delete it and then redeploy it.

I would use 'rm -r /opt/CPrt-R80/log_indexer/targets/*'  (as with any other time that you use rm with a wild card, I would advise to exercise caution and make sure you are deleting the right location/content and nothing else).

I think we could have and should have handled this scenario better. This sort of mixup and confusion is why this should have been blocked in my opinion (I already have an open RFE to block deployment in case the $EXPORTERDIR variable is not defined).

Edit: Just noticed that the command should be: cp_log_export delete name XXXX  (you're missing the name parameter)

Hey Yonatan, thank you so much. it worked for me.

Even though adding the corrected parameter(name) didn't help, but removing the target directory and recreating it helped for me.

Expect new ports with R80.20. There is something going on on port 4434 that is web related.

Hello Hugo,

I saw your post on regarding the R80.20 M1 release.

I have to admit I wasn't aware of any issue with the ports and I've asked the relevant person to look into it.

I'm not familiar with any planned change to the log exporter ports in R80.20.

Nor am I familiar with any new issue with the Log Exporter on R80.20.

If you are aware of any specific issue with the Log Exporter on R80.20 M1 please send me an email with details to (edited as we are already GA for R80.20)

Thanks!

What are the performance implications of installing the Log Exporter?  What is the typical cpu/memory footprint?

Each log exporter can consume up to 1 CPU when exporting in full capacity.

I installed a log exporter on a fairly busy log server.  The log_exporter process immediately jumped to ~100% cpu (1 core).  Does this mean I need to install multiple log_exporter processes?  If so, how do I do that? 

Are there any troubleshooting commands I can use to see if the log_exporter process is not able to send all logs to the syslog server?

You don't really need to do any troubleshooting just yet - a CPU spike is expected after enabling the process for the first time.

The process will export all logs going back (by default) 1 day and will start exporting them at the maximum possible rate until it empties the queue, at which point it will go into the 'steady state' of exporting logs as they arrive.
This is the expected behavior. If the process goes down for any reason it will not lose any logs as we save a record of which logs were exported, and any that were not will be exported as soon as the process is back up and running. 

Depending on how many logs you generate per day this can take anywhere from a few seconds to a few hours.

From the screenshot, it looks like the process has been running for 4 hours already which leads me to believe you probably generate a large number of logs per day.

If the process is still at 100% CPU after a few more hours I would check the elg file to see what is the current, average and total amount of logs exported (the 'cp_log_export status' command will also give you the path to the elg file).

If the CPU load persists for more than a day, this might be an indication of a problem and you should investigate further and/or open a support ticket.

Thank you very much for your quick reply!  Yes, after a few hours, things seem to have calmed down, and the process is ~ 15%.  Thanks for the explanation!

Your output actually indicates that everything is working as expected and that you have already exported ~2.5M logs at an average rate of 1.6K logs/sec:

You have also exported 12 audit logs (I'm assuming this was the value that confused you - the elg has information for both fw.log and fw.adtlog):

A useful debugging tool is the following command:

This will allow you to see the actual logs in real time as they are being exported.

If you are also sending OS logs or sending logs using other methods on the relevant port you might want to add more filters to the tcpdump command.

We have a new deployment coming up, which will require SPLUNK feeds for traffic and audit logs. We already have both OPSEC & LogExporter defined on our existing R80.10 platform. We use OPSEC LEA for SPLUNK, and LogExporter for a different SIEM system.

As LogExporter is currently installed as an HFA, it is an additional overhead when carrying out upgrades.

Is there any big reason why we should be using one of these solutions over the other?

Thanks.

Log Exporter should be independent of HFAs

Alex_Tooze

It isn't, as far as I am aware. In order to install a new JHFA, it is currently necessary to remove LogExporter, then previous JHFA, before installing the new JHFA and reinstalling LogExporter.

The main point of my question, though, is whether we should be using LogExporter in preference to an OPSEC LEA connector, or stick with tried-and-tested OPSEC.

From Check Point’s perspective Log Exporter is the preferred integration going forward. Having worked with LEA for a while would say LEA provides more hooks, but lacks one key thing that Log Exporter offers, mapping Check Point logs to another format; CEF, LEEF, Splunk (CIM), etc.

Aside from LEA's lack of 64 bit support, one of the biggest challenges an integrator may have is mapping Check Point fields to their taxonomy. Currently our taxonomy isn’t well defined or uniform across our products, i.e. one product may use a different field name from another product. We're working to better define our log fields (see Threat Prevention Log Field Documentation ), but Log Exporter can also help by normalizing these fields into a common format. For example see Log Exporter CEF Field Mappings .

Hello,

 

I just recognized that after enabling Log Exporter on R80.10 management the feature started to export the logs of the past one day. After this has been completed, actual logs are exported as expected.

The problem is that the /opt/CPrt-R80/log_exporter/targets/SIEM/log/log_indexer.elg file is continuoulsy growing at about a 500-600bytes/5s pace under "normal" circumstances (=no error messages just info about the normal operation of Log Exporter) when the logs are exported.

You can see an example screenshot of the logs below.

First question: this growth consumes disk capacity under /opt (/dev/mapper/vg_splat-lv_current). Will this log_indexer.elg file deleted or archived somehow automatically or do I have to do it manually?

Second question: what does the message containing "SyslogTCPSender::shouldRetry: Socket: [14] was write-blocked" mean? Is it an error or..?

That is the current design.

1. As all debug logs, it allows only 10 of these & then the oldest one is deleted, so no worries about disk-space.

2. This message is okay, it's meant for internal debugging purposes.
