Migrate configuration - Mongodb and Content Pack

Graylog Central (peer support)
1

Hi all, following this post Migrate configuration or Upgrade?
i got a clear installation of Graylog 2.4

In order to migrate configuration from Graylog 2.0 to Graylog 2.4 i got stuck on migrate mongo Database.

root@graylog:~# sudo mongodump -h 127.0.0.1 -d graylog -o /home/ubuntu
connected to: 127.0.0.1
Wed Dec 12 13:03:24.023 DATABASE: graylog to /home/ubuntu/graylog
root@graylog:~# ls /home/ubuntu/

/home/ubuntu/ is empty (note that i try also using root user)

Also check mongodb vs mongodump version

Any ideas? thanks!

Hi again, in old graylog (v2.0 OVA)

I run this commands:

imagen
imagen.png632×501 77.4 KB

(WARNING: Insecure configuration, access control is not enabled .)

I don’t understand why i can’t see tables.

Same commands on the new graylog 2.4, mongodb v3.6.9 :

Any help will be appreciated, thanks!

I see that you connected without authenticating.

@jan, does the Graylog OVA not use an application account for Graylog in MongoDB?

Thanks for reply @Totally_Not_A_Robot, i think that too, but i get this message when i connect to mongodb:

“** WARNING: Insecure configuration, access control is not enabled and no --bind_ip has been specified.
Read and write access to data and configuration is unrestricted,
and the server listens on all available network interfaces.”

Still get no file with mongodump.

Thanks!

I’m not sure about that old version. Might be not implemented at that point.

@monchito sorry I’m not able to investigate in this, but I guess someone else is able to help you.

Hi, there is another way to the export the db … get json file or something like that?

Thanks!

Of course :slight_smile: I don’t use mongodump in our environment, I use mongoexport…

Hi again, first: thanks so much for helping.

I exported content pack and mongodb (with mongoexport/mongoimport) it have to make 1 command per collection, here are the commands, maybe it is usefull for someone with the similar issues.

Collection from v2.4 (i can’t see on v2.0.3)

Collections:

alarmcallbackconfigurations
alarmcallbackhistory
alerts
cluster_config
cluster_events
collectors
content_packs
grok_patterns
index_failures
index_ranges
index_sets
lut_caches
lut_data_adapters
lut_tables
nodes
notifications
pipeline_processor_pipelines
pipeline_processor_pipelines_streams
pipeline_processor_rules
roles
sessions
streamrules
streams
system_messages
traffic
users

Graylog Server 2.0.3:
mongoexport -d graylog -c collectionName -o /home/ubuntu/mongoExport/collectionName.json

scp -r user@x.x.x.x:/home/ubuntu/mongoExport/ /home/user/mongoExport

Graylog Server 2.4:
mongoimport --drop -d graylog -c collectionName --file collectionName.json

Rapidly i found Alerts in the new server is empty, maybe is handler diferent i gonna check more granularity.

Thanks!
