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 !

Kind regards
Ivan

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
