Graylog Collector Sidecar: Collector section is not available

Hi Guys,

I installed graylog collector sidecar on my client machine which should send logs to my Graylog server. Moreover I installed below plugins in my plugin folder (on server):

… and after that I restarted graylog container (yep, I’m using docker)

However in web browser there is no “Collectors” section in “System” menu. Do you have any idea why? Should I wait a bit longer? Maybe install something more? Kindly please for your support!

The Graylog Collector plugin is installed by default and it shouldn’t be necessary to install it manually.

How did you install Graylog?
What’s the configuration of Graylog?
What files are in your plugins directory?
What’s in the logs of your Graylog node?

You’re right. When I wrote “installed” I meant that I copied jar file to /srv/graylog/plugin:

[root@monitor-host ~]#  ls -l /srv/graylog/plugin/
total 192
-rw-r--r--. 1 root root  27028 Jul  7 14:12 graylog-plugin-beats-2.2.3.jar
-rw-r--r--. 1 root root 115405 Jul  7 14:40 graylog-plugin-collector-2.2.3.jar
-rw-r--r--. 1 root root  47876 Jun 22 12:35 graylog-plugin-input-jmx-1.0.2-SNAPSHOT.jar

This should work, I used jmx plugin without any doubts.

I installed graylog as container in docker. I Installed it:

sudo docker pull graylog2/graylog
docker-compose up -d

Node logs are (I suppose that you asked about http://[ip.of.graylog.server]:9000/system/nodes/33b3adfb-xxxx-xxxx-xxxx-df330d770797

Is the plugin listed in the logs of your Graylog node on startup?
Could you try running the Graylog container without the JMX plugin to rule out any incompatibilities?
Also, are there any error messages in the logs of your Graylog node or in the Developer Console of your web browser?

I tried to erase other plugins. Now in my plugin folder I have only:

However after restarting my container I have in System menu only:
Content Packs
Grok Patterns

I’ve got no error logs - every container works fine, GraylogWEB->System->Overview - no errors.

Moreover from my client machine I’ve got this sidecar status:

What’s in the logs of the Graylog node?
Are there any errors in the Developer Console of your web browser?

Logs were ok. In DC there are no errors.

However I copied to plugin folder some additional plugins.

[root@monitor-host graylog]$  ls -l /srv/graylog/plugin

Maybe some of them were responsible for make collectors section visible. I don’t know, but it works… Any idea why? Nevertheless problem is solved now.

I’ve got these packages from (plugin folder). By the way when I delete all jars but not beats, collector and jmx, Collector section is still visible. When I delete graylog-plugin-collector-2.2.3.jar, restart docker and copied again graylog-plugin-collector-2.2.3.jar and again restart - Collector is invisible. I need to copy all of these jars again and delete all until in plugin folder will be these three jars - beats, collector and jmx. Then it’s ok. Creepy issue.
