Hi Jim, Thanks for the feedback. The problem is that im trying to monitor big infrastructure ( 200 Physical servers and more than 1000 VMs ). So currently i have install with MongoDB and have 300MB for one week monitoring just two VMs. The server syslog-ng and one client VM. Also i have used before syslog-ng with MariaDB (MySQL) but i have problem that i have 90% CPU Load when i used MySQL. I can't fix it. But now using MongoDB i have other problems. Using LogAnalyzer i can't see the "Date", "Facility", Serverity etc. on a main page but when i go to the log itself or i open it i can see all this informations. So i have the following 1. Syslog-NG with MySQL and LogAnalyzer ( works ok but CPU Usage was big ) 2. Syslog-NG with MongoDB and LogAnalyzer ( works ok but no informations shown on a first page ) So i can't find solutions and i need this sh*** up and running ASAP :) Any solutions or suggestions im open to see it !

My 2 cents (what works for you depends on your infrastructure, resources and capabilities)
I like the model where syslog-ng does all the following:
- writes text files of the raw data (that way - whatever your search head is can re-ingest files later using basically the same parsers)
- filters out highly false-positive prone data from being forwarded
- handles parsing of data elements (using patterndb or whatever) and sends specific information to a search engine (like Elasticsearch)
- forwards specific data (based on security use cases) to a SIEM
Whether you use Elasticsearch, mongo, splunk, or whatever is really up to you and your budget. That said, I find syslog-ng to elasticsearch directly with kibana as the front end is *very* scalable for a search engine.
As far as a SIEM - it's kind of up to you.
Good luck,
Jim

Hi all,
What is the best practice for storing all those logs in one central environment. I have one Linux Box running Syslog-NG with LogAnalyzer and MongoDB ( for now ), and is the best way to configure and use it with MongoDB or with MariaDB ( MySQL ) ? I have once install MySQL but it was getting very slow as the logs getting bigger and bigger ( for one week ). Now i have done with MongoDB ( still testing ) but i have problem as LogAnalyzer does not show me the real pictures, i have no Date info, no Facility, no serverity, Hosts, syslogtag, i just have ProcessID.
Any hints on this ?
I have the following configuration on the syslog-ng.cfg:
destination d_mongodb { mongodb( servers("localhost:27017") database("logs") # uri('mongodb://localhost/syslog-ng') collection("syslog") value-pairs( scope("selected-macros" "nv-pairs" "sdata") ) ); };
Kind regards Ivan
