Hi Richie,

I'll do that too, the think that scares me is that I'm running maybe two weeks this syslog-ng and i have 400 MB of logs and im logging just 2 Machines, the Server itself and on Client.
And im planning to loging more than 1500 machines. So im not sure what to choose. MongoDB, MySQL, or PostgreSQL.

And for now i have problems with all of them :)


Kind regards
Ivan

Hi,

I would try mysql/mariadb tweaks also:
- index(or indices) on one or more column(s) of the mysql table according to the queries of loganalyzer
- check the different cache and buffer options in your mysql conf
- my opinion and experience is that mysql partitioning can do magic on this amount of data. A query could run only on few gigs portion of data (and a good indexing accelerates the query of these few gigs also).

Unfortunately your mongodb problem remains open.

Regards, Richie

Nop,
Again same problem:
Here is what i have done

destination d_mongodb {
        mongodb(
        servers("localhost:27017")

        database("syslog")
        username("Ivan")
        password("Ivan123")
        collection("messages")

        value-pairs(
            scope("selected-macros" "nv-pairs" "sdata")

            pair("date", datetime("$UNIXTIME"))
            pair("pid", int64("$PID"))
            pair("program", "$PROGRAM")
            pair("message", "$MESSAGE")
                )
                        );
                        };
Still have the same problem no info on date no nothing. The strange part is that when i open a specific log i have all the info. The only problem is where on a first page on the LogAnalyzer i don't have this problems.

And yes again we may have two problems: One is the DB information how its stored, and by this i think we stored as we should, but do i have to configure some tables in the MongoDB or columns or something ( that is how i did it with MySQL ). The second is something wrong with the LogAnalyzer so now im going to reconfigure with PostgreSQL and again with MySQL to see if something will be change.

Hi, 

Do you know in what type does loganalyzer expect the specific fields? 

AFAIK, by default, syslog-ng sends everything as string, but for the mongodb destination, you can specify the data type, see https://www.balabit.com/sites/default/files/documents/syslog-ng-ose-latest-guides/en/syslog-ng-ose-guide-admin/html/specifying-data-types.html

Try sending the date as datetime, and the others as numbers, maybe it helps.

Robert

Robert,
i just thought of that and goggling how to add columns or some other similar scenarios, i think that the problem lays on how syslog-ng send the logs in the DB. Or how DB is storing this messages. As i have not configure nothing on the MongoDB just username and password for already created DB by the syslog-ng.

If some one have some tips, ill be happy to try it :)

Kind regards

Hi, 

can you check the mongodb itself if the related fields/tags/whatever are in place?

I mean, the problem might be in how syslog-ng sends the data into MongoDB, or in how loganalyzer reads the data from MongoDB. Is there a way for you to find out which?

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
