ELK + pfSense 2.3 Working

ando1

For anyone interested in getting the newest version of ELK (v5) working with pfSense, I was able to get do it using the instructions on this siye: http://pfelk.3ilson.com/

You need at least Ubuntu server vv16.04.01

@ando1:

Can you post the output of the logstash debug? You may need to stop the service before you run the command:

/opt/logstash/bin/logstash agent -f /etc/logstash/conf.d/ –debug

Also what error do you get when you run this?

/opt/logstash/bin/logstash --configtest -f /etc/logstash/conf.d/

/opt/logstash/bin/logstash agent -f /etc/logstash/conf.d/ –debug

Error: Expected one of #, input, filter, output at line 1, column 1 (byte 1) after  {:level=>:error, :file=>"logstash/agent.rb", :line=>"214", :method=>"execute"}
You may be interested in the '--configtest' flag which you can
use to validate logstash's configuration before you choose
to restart a running system. {:level=>:info, :file=>"logstash/agent.rb", :line=>"216", :method=>"execute"}

/opt/logstash/bin/logstash –configtest -f /etc/logstash/conf.d/

You definitely have a config file issue. Logstash combines all the configuration files into one and then processes them. Since the error is at Line 1 column 1 it sounds like the problem may be in the 02-inputs file. Have a look at all config files and double check they are OK.

if can creat ova or ovf from vm machine and upload it its very good :)

http://pfelk.3ilson.com/ basically works, but some pointers:

1/ There's a PPA for MaxMind:

sudo add-apt-repository ppa:maxmind/ppa

see http://dev.maxmind.com/geoip/geoipupdate/ for /etc/GeoIP.conf and run geoipupdate after that. The DB is located in /usr/share/GeoIP/GeoLite2-City.mmdb

2/ You really should set up some authentication:

https://www.elastic.co/guide/en/x-pack/current/setting-up-authentication.html

Yeah I had issues with the date stuff in logstash config as well.. had to remove the +0400 and timezone..

I have it running, but elasticstack doesn't seem to want to stay running. Haven't had time to look into why. And have not had any time to do any visualizations - which is what everyone wants ;)

Make sure you've allocated at least 4GiB of RAM to this thing. (Java >:( ::))

I run elk stack on 1.5 ;D

Small office though. Thx for the info on auth.. I've been wondering how to do that.

I'm currently going through the process of installing ELK but I have an important question. If I redirect the logs from pfSense to the ELK server will I be able to access the raw logs somewhere? I need to have them somewhere and I'm wondering where they would be if they are sent to ELK.

BrunoCAVILLE

Eveything works well except the maps visualization, someone can help?

Up

Logstash stops after a few seconds (rising heap size didn't help).

Status Menu - System Logs - Settings - and jump to : Remote log servers - and you can add another 2 Syslog Servers you have ; ex syslog-ng, Splunk etc

Hi all,

trying to get this going with PFsense 2.3.4 and ELK 5.4 - all components are talking ok, and I can get the JSON Dashboard, Search and Visualization up and running - almost…:

when I import the visualizations, Kibana complains that the tags geoip.country_name and geoip.city_name are not available.
I checked 11-pfsense.conf (which I used from this site) against the spec at https://www.elastic.co/guide/en/logstash/current/plugins-filters-geoip.html, and there does not appear to be any issue with this - that is, it looks like those tags should be returned.

Anything else I could check, or logs I could provide?

kind regards

Ron

the log send from pfsense where is save on elk?
i change the elk server and how to export import log on prvise server?

Any differences to get this running on 2.4.0 BETA?

I finally got this up & running on pfSense 2.4.0 BETA with the help of AR15USR and some people on IRC.

Initially I was having trouble getting the Index Patterns to populate in the first step of Kibana. I had followed doktornotor's advice for setting up MaxMind. For whatever reason that didn't work for me so I just did it according to http://pfelk.3ilson.com/ and it worked.

Next, I had everything stable and logs being imported, but all logs were being tagged "_grokparsefailure" & "_geoip_lookup_failure" and since the pattern wasn't matching, it wasn't putting out any useful fields/information. This was also preventing me from importing the Visualizations.json due to not having the applicable fields available.

After way too much time troubleshooting and trying to figure out what was happening and why I was given some direction and pointed to the grok debugger by a kind IRC user. https://grokdebug.herokuapp.com/
For anyone looking to troubleshoot or modify their own grok pattern files, here's what I could make of the fields in 2.4.0 BETA's Rsyslog format. https://forum.pfsense.org/index.php?topic=133354.msg733494#msg733494
Run a pcap to see exactly what your pfSense box is sending to your ELK server.

It turned out that all I needed to do was change one character in /etc/logstash/conf.d/patterns/pfsense2-3.grok and reboot.

I changed line 16 (PFSENSE_LOG_DATA)
From:

PFSENSE_LOG_DATA (%{INT:rule}),(%{INT:sub_rule}),,(%{INT:tracker}),(%{WORD:iface}),(%{WORD:reason}),(%{WORD:action}),(%{WORD:direction}),(%{INT:ip_ver}),

To:

PFSENSE_LOG_DATA (%{INT:rule}),(%{INT:sub_rule})?,,(%{INT:tracker}),(%{WORD:iface}),(%{WORD:reason}),(%{WORD:action}),(%{WORD:direction}),(%{INT:ip_ver}),

That's it, one "?".

After that, log files were parsing successfully, I refreshed my Index Pattern Field List to pull in all of the new fields, imported the Visualizations.json and opened up the Dashboard. All is working now on my single core atom with 2GB DDR2!

I have this up and running (for home use) on an old netbook with an atom N450 (Pineview ~2010, single core 1.66GHz) with 2GB DDR2. I had to significantly lower RAM usage in the following two files to get it working. Currently using <1.5GB RAM, the OS is lubuntu with GUI service disabled. It's also running a Unifi controller. Dashboard is slow to load even for a small home network but it works! I couldn't justify buying anything to get an ELK stack for my home network.

@BrunoCAVILLE - I'm having the same problem as you did. I used the revised visualization file due to the .keyword issue. I've attempted to merge back in the country sections from the http://pfelk.3ilson.com/ visualization file, but still no luck. Just wanted to know if you were able to identify/ resolve the issue?

https://forum.pfsense.org/index.php?topic=125376.0

pfBasic

Did you refresh your fields list (Management / Index Patterns) after a number of your log files were successfully parsed?

If not, do that first then try to import the pf3lk visulization.json.

The import fails if you don't have the appropriate fields available.

I just wanted to add that the Kibana4 init script from the OP is no longer listed via a link as others were so I wanted to copy it here in text form as it did take me a moment to realize that the scripts were all included in a zip file in the op as well.
