Graylog - Message Enrichment
We take a look at 3 ways to enrich messages in Graylog. Static fields, CSV, and API lookups.
We explore lookup tables, data adapters, and pipeline rules. We will explore how we can dip into the LibreNMS database using the API, and insert data into the message.

This was some great info, thanks!
Thank you very much. Really appreciated!
I installed everything as per the instructions, but I am still getting "502 Bad Gagway | nginx/1.18.0 (Ubuntu)" in the browser. I am not sure what is the issue. I am using VirtualBox with Ubuntu Server 22.04.4 as OS, and PHP version is 8.1.2.
@@bharaninathkomandur6330 check your phpfpm config
@@fordayinlife thank you for the quick response. There was an error in php-fpm and one php path in nginx. Changed them and it started working.
I just built my Graylog server to collect and analyze my OPNsense logs (filterlog for now) and I have literally zero knowledge on how use that tool. I managed to set up sending logs to Greylog and now it's time to make the next steps. Your channel is exactly what I was looking for :)
It is not /etc/php/8.1/fpm/php it is /etc/php/8.3/fpm/php, their own installation guide is outdated!
Thanks for your video. As I never wrote anything in python, I cannot guess what is written on the right part of your script... so frustrating !!! I would libe to see a working exemple before modifying it or create my own. Regards.
Yeah I'll try and find the script, but to be honest I was just pointing out the exit codes not that anyone should use that script.
ThankYou!
For anybody else averse to vi, do this before running any scripts: alias vi='nano'
Hi, thanks for all these videos on graylog. You should use "systemctl edit graylog-server" to override the unit. This will create a file (/etc/systemd/system/graylog-server.service.d/local.conf) with just the additions to graylog-server.service. That way you don't touch the original file and your changes will survive on upgrading (this is systemd standard feature).
very helpfull, thank you

Hello, I try librenms in my aws academy but everytime i logged out the ip address changes what should i do?
Amazing video, guess I should watch other too thankyou dude.
top notch tutorial!!!
Guys look! A birdie!
In the docker compose file you can add a restart unless stopped
By the way, the music is good too :) it feels cozy, thanks
Hey thanks! That's awesome. Kinda was a last minute add but I had been working on the track for the last couple weeks .
Brilliant! Clear and concise 👍the best thing I've seen on this topic
Really good, but could you help me with one question please? I set up the GUI but how do I connect my other servers? Do they need a agent?
Mercii beaucoup, tout fonctionne parfaitement, très bonnes explications !!
I just use ports above 1024, since I am already defining a separate port for each input
Thanks man, this was really helpful!
Dude... this saved me so many hours. Thanks!!!
Very nice series of videos! Could you elaborate a bit more in one of the next videos around the Authentication story you mentioned at the end of this one for all the streams you have? I am missing a couple of bits left and right there...
After on the SNMP when the device adding then shows " couldn't connect to .... please check the snmp details.
SNMP community is wrong or LibreNMS can't access it. Check force add to bypass the checks, but it will show down until you fix SNMP/ping
@@fordayinlife Thanks for your reply. It has worked but not showing ALL DEVICES bar
Thanks
Great info AMP!!
I have a problem because I only see a white page, on the taskbar I have the LibreNMS icon.
Thankyou for your video great explaining and demonstration you'r the best !
Thanks for the nice vid, appreciate if you could create another video on how enable TLS/https on the login page.
Thanks for the good video! I would like to know whether the communication between log sources (senders) and the Graylog server secured by TLS encryption?
They can be if they the sender supports it, in my experience (not likely).
It works bro, thanks for the awesome tutorial video 👍
Do we have Postman collection for APIs ?
Love your videos. Thanks you! Can you make a video on how to upgrade graylog to the latest version?
We have installed distributed poller watching your video and we are running dispatcher services but we have one issue graph are not generating.Please help
thank for the graylog video :) I am very new with graylog and start to build demo graylog's architecture to save the log data. I would like to ask about is it possible to set index name as daily format? (ex. graylog_20240215, graylog_20240216) The default setting produces index name like 'graylog_0' ...
What issue are you trying to solve? If you want ALL logs from a certain time period I would be using the date selectors when searching. I don't think you can change that format,
@fordayinlife Thank you for the quick response! There are no issues, but I would like to know whether I can handle Graylog's index name as I want. Here is my plan for the graylog system: 1) generating graylogs' index and setting its name as daily format (ex. graylog_20240216...) 2) Making a snapshot for the index and saving it to AWS S3 by opensearch dashboard 3) Delete the old index with certain rules (ex., deleting the old index after 6 months). 4) Restoring the deleted index from AWS S3 by opensearch dashboard when I want. 5) For this purpose, I would like to set the graylog's name as a daily format to pick up and restore it by using file name.
so any changes I'd like to remain persistent will be inside the librenms folder, ie: config.php?
Watch my video on configuration.
@@fordayinlife I was referring to the docker compose, but I scrapped that idea. Ill be doing my other pollers as containers however
This installment in your Graylog series was worth the wait. I think I finally “get” grok patterns now. I would love to see how pipelines can parse JSON into key value pairs (idea for future video). I know I can do it with string matching and grok patterns but that seems fragile and inefficient.
hey. I followed step by step guide and it's end-up showing bad-gateway error while tried to check for pre-install check. can anyone give me the solution for this error?
check your error log for nginx and the path /run/php/php-fpm-librenms.sock to listener are same i suppose it is different
Very nice explanation for pipeline. But I have one question: I've did it for my source field with the input is localhost to be changed to a specific IP of the server. But the problem is any servers coming in graylog with the source named localhost were changed to this IP (as the pipeline rule I set). So how do I distinguish different IPs from different servers which coming into graylog with the same name localhost? Tks!
Gl2_remote_ip key ALWAYS has the IP that sends the message.
@@fordayinlife it's weird for my case, I've never seen any messages if I filter Gl2_remote_ip key, so I always have to use source or SourceModuleName or ServiceName to be able to looking up for the messages.
Excellent introduction! I just updated my graylog server to the latest today, so seeing this video is a nice surprise!
Im running the latest package version on Ubuntu 22.04, Graylog 5.0.13 and I dont have that fancy rule builder.
Introduced in Graylog 5.2... you need to upgrade
@@fordayinlife noooooooooo. haha. Ok thank you. Great video btw.
you seriously did a great job breaking down the basics of pipelines. I can expand on this now and create multiple fields in my messages. Wonderful job !
Great video and explanation! I have so many questions that the documentation leaves ambiguous about and you help fill in the gaps. Big thanks on explaining the document size and message count. I look forward to your continued examples.
Thank you, all guide I've seen said the PASSWORD_SECRET was the actual password. I used your generation method and I stopped getting my HS256 Key was too short. I've rebuilt my environment 4 times and cleared all graylog data 10-15 times to get different things to work.
perfect guide thanks. subscribed.
