Good day all, I'm new to this mailing list. I'm setting up syslong-ng+elasticsearch+kibana on an Ubuntu 18.04; i'm getting the following output/error from command: ]#syslog-ng -Fve Error parsing destination, destination plugin java not found in block destination elasticsearch2 (at /usr/share/syslog-ng/include/scl/elasticsearch/plugin.conf:58:1): 1 2-----> java( 2-----> ^^^^ 3 class_path("/usr/lib/syslog-ng/3.15/java-modules/*.jar:/usr/lib/syslog-ng/3.15/java-modules/elastic-jest-client/*.jar:/opt/syslog-ng/jre1.8.0_171/lib//*.jar") 4 class_name("org.syslog_ng.elasticsearch_v2.ElasticSearchDestination") 5 option("index", "*log*") 6 option("type", "syslog") 7 option("server", "localhost") Included from /etc/syslog-ng/syslog-ng.conf: 90 # Debian only 91 destination d_ppp { file("/var/log/ppp.log"); }; 92 93 # Elasticsearch destination 94 destination d_es { 95----> elasticsearch2( 95----> ^^^^^^^^^^^^^^^^ 96 cluster("syslog-ng") 97 client-lib-dir("/usr/share/elasticsearch/lib/") 98 client-lib-dir("/opt/syslog-ng/jre1.8.0_171/lib/") 99 time-zone("UTC") 100 cluster-url("http://localhost:9200") Any help is welcome.

Re: [syslog-ng] Unbale to mount syslog-ng.conf to /etc/syslog-ng using docker image

Hi, Thanks. It might be possible that you have SELinux enabled on your system. Give it another try using the :Z flag: docker run -it -v /demo/syslog-ng/syslog-ng.conf:/etc/syslog-ng/syslog-ng.conf*:Z* --name syslog-ng -p 514:514 -p 601:601 balabit/syslog-ng:latest Please note that you are using the latest edge version of Docker with the devicemapper storage engine. It has nothing to do with your issue, but I would consider switching to the stable version (with overlay2). https://docs.docker.com/install/linux/docker-ce/centos/ -- László Várady On Sun, May 27, 2018 at 12:56 PM Mujeeb Baig <baig.mujeeb(a)gmail.com> wrote: > Hi, > > Docker info output > > root@hdata3:/home/smb/code/conf# docker info > Containers: 0 > Running: 0 > Paused: 0 > Stopped: 0 > Images: 0 > Server Version: 18.05.0-ce > Storage Driver: devicemapper > Pool Name: docker-8:1-100670142-pool > Pool Blocksize: 65.54kB > Base Device Size: 10.74GB > Backing Filesystem: xfs > Udev Sync Supported: true > Data file: /dev/loop0 > Metadata file: /dev/loop1 > Data loop file: /var/lib/docker/devicemapper/devicemapper/data > Metadata loop file: /var/lib/docker/devicemapper/devicemapper/metadata > Data Space Used: 11.73MB > Data Space Total: 107.4GB > Data Space Available: 51.36GB > Metadata Space Used: 581.6kB > Metadata Space Total: 2.147GB > Metadata Space Available: 2.147GB > Thin Pool Minimum Free Space: 10.74GB > Deferred Removal Enabled: true > Deferred Deletion Enabled: true > Deferred Deleted Device Count: 0 > Library Version: 1.02.146-RHEL7 (2018-01-22) > Logging Driver: json-file > Cgroup Driver: cgroupfs > Plugins: > Volume: local > Network: bridge host macvlan null overlay > Log: awslogs fluentd gcplogs gelf journald json-file logentries splunk > syslog > Swarm: inactive > Runtimes: runc > Default Runtime: runc > Init Binary: docker-init > containerd version: 773c489c9c1b21a6d78b5c538cd395416ec50f88 > runc version: 4fc53a81fb7c994640722ac585fa9ca548971871 > init version: 949e6fa > Security Options: > seccomp > Profile: default > Kernel Version: 3.10.0-693.21.1.el7.x86_64 > Operating System: CentOS Linux 7 (Core) > OSType: linux > Architecture: x86_64 > CPUs: 2 > Total Memory: 7.147GiB > Name: api-es-syslog-ng-2 > ID: HOBZ:AVPN:MRVO:JAMW:YZFU:SF5M:LTFF:7H7Y:BKBA:MNV4:OMY3:4IJM > Docker Root Dir: /var/lib/docker > Debug Mode (client): false > Debug Mode (server): false > Registry: https://index.docker.io/v1/ > Labels: > provider=google > Experimental: false > Insecure Registries: > 127.0.0.0/8 > Live Restore Enabled: false > > WARNING: devicemapper: usage of loopback devices is strongly discouraged > for production use. > Use `--storage-opt dm.thinpooldev` to specify a custom block > storage device. > > > On 25 May 2018 at 18:21, László Várady <laszlo.varady(a)balabit.com> wrote: > >> Hi, >> >> Thanks. >> >> Could you share what version of Docker you are using? >> The output of "docker version" and "docker info" might be interesting. >> >> -- >> László Várady >> >> On Fri, May 25, 2018 at 6:41 PM Mujeeb Baig <baig.mujeeb(a)gmail.com> >> wrote: >> >>> Hi Laci >>> >>> Here is the output, this time I created another folder /demo/syslog-ng >>> and copied the syslog-ng.conf file there, but same issue.

exclude empty pairs from json-parser()
by Nik Ambrosch 23 May '18

23 May '18

Hi - I'm trying to figure out how to instruct json-parser() to exclude empty (or nonexistent) json pairs from being passed to it's template. This is possible with the csv parser using null("") but not json. It seems that if i specify all my json-parser() pairs using --pair example=\"${MYMACRO}\" the desired behavior is achieved, however using --scope nv-pairs instead will log the empty values.

syslog-ng Open Source Edition official binary repository
by Gergely Bodnár 23 May '18

23 May '18

Dear syslog-ng users, Last autumn, we asked for your feedback ( https://syslog-ng.com/blog/new-website-and-official-repo-coming-up-tell-us-…) on our plan to introduce official binary repositories for syslog-ng Open Source Edition. The overwhelming majority of those who got back to us agreed that it is fair to provide this service tied to a simple registration. We are happy to announce that although a bit late compared to our originally planned schedule, we are launching this service, first as a test run with Debian Jessie packages. We will always host the latest release, and these packages will be built and tested by us, so you won't have to worry about dependencies - provided you are running a suitable Linux distribution. We are planning to add an RPM repository as well in the future, knowing well that many of our open source users require that. How to use repository? ------------------------------- To use the newly introduced syslog-ng Open Source Edition Debian Jessie repository, you only have to complete a few quick and easy steps. 1. Create a MyBalabit account (https://my.balabit.com/signup) Just click on MyBalabit in the top right corner of the page, and then choose Sign Up (under OS X, the sign up option will be hiding under the hamburger menu). At the top of the form, there will be a drop down menu where you have to specify why are you requesting access to this portal. Choose syslog-ng OSE Binary Repository Access, then fill out the rest of the form, read and agree to our privacy policy, then hit create you account.If you already happen to have a MyBalabit account, simply log in and look for Request Access in the top menu. Once in there, select syslog-ng OSE Binary Repository Access and click on request access. 2. Once you finished with the initial steps, look for the Access tokens option at the bottom of the left menu bar. In there, you will find your token to be used with the syslog-ng OSE DEB repository. If for some reason you need a new token, use the regenerate button. 3. Now you should be all set to configure your compatible Linux distribution to access the repository. # echo "deb http://JXJiI9Znyt:@apt.syslog-ng.com/syslog-ng-ose jessie main" >/etc/apt/sources.list.d/oserepo.list # apt-get update # apt-get install --no-install-recommends -y curl # curl http://JXJiI9Znyt@apt.syslog-ng.com/syslog-ng-ose/pubkey.gpg | apt-key add - # apt-get update # apt-cache policy syslog-ng # apt-get install syslog-ng And that's it, you should be all set! Please, don't forget that this is still very much a trial for us to gauge the interest in such a service. Bugs might surface, the repository might be inaccessible due to technical glitches, etc. We encourage you to share your feedback with us. It would be much appreciated!

Forwarding flat files to a remote syslog-ng server

22 May '18

Hi, I'm trying to send various flat files to a central syslog-ng server. So, I have the following setups but somehow using the "local1" and "local2" facilities don't work, although no errors when restarting syslog services on both client & server. Any advice would be appreciated much! ======================================================================= My syslog-ng CLIENT (running syslog-ng 3.6.2): source s_file1 { file("/var/log/syslog/file1.log" follow-freq(1) flags(no-parse) program_override("audit")); }; filter f_file1 { facility(local1); }; destination d_file1 { syslog("10.10.10.10" transport("udp") port(514)); }; log { source(s_file1); filter(f_file1); destination(d_file1); }; source s_file2 { file("/var/log/syslog/file2.log" follow-freq(1) flags(no-parse) program_override("audit")); }; filter f_file2 { facility(local2); }; destination d_file2 { syslog("10.10.10.10" transport("udp") port(514)); }; log { source(s_file2); filter(f_file2); destination(d_file2); }; ======================================================================== My syslog-ng SERVER (10.10.10.10 - running syslog-ng 2.0.9): destination d_file1 { file ("/var/log/syslogs/file1-$YEAR$MONTH$DAY.log" owner(root) group(root) perm(0644) dir_perm(0755) create_dirs(yes)); }; filter f_file1 { facility(local1); }; log { source(remote); filter(f_file1); destination(d_file1); }; destination d_file2 { file ("/var/log/syslogs/file2-$YEAR$MONTH$DAY.log" owner(root) group(root) perm(0644) dir_perm(0755) create_dirs(yes)); }; filter f_file2 { facility(local2); }; log { source(remote); filter(f_file2); destination(d_file2); }; Thanks. - Young

Best way to pipe "application" logs to central syslog-ng server.
by Delon Lee Di Lun 09 May '18

09 May '18

Hi, I am working on a mini project that requires the receipt of "application" logs using rsyslog client to pipe it to a syslog-ng central server. An example of the "application" logs im referring to would be for instance Apache HTTPD logs, I want to separate the "application" logs, in this example, the apache logs, and the "OS" logs into different directories. I am thinking of certain crude way, using regex to filter the messages at my server end ,to do it which might not be as clean. Would like to ask the floor if anybody had experience with working in this environment. Would change my rsyslog client and my syslog-ng server to use RFC5424, IETF's compare to the legacy BSD syslog protocol help? Comparing the headers there is a "app-name" variable in the IETF's syslog protocol I can use? Yours Sincerely, Delon Lee
