Hi,

Regarding the Elasticsearch module:

Currently, I am using Nxlog Manager, NxLog agent and I want to send the log to elasticsearch. Where I should put the elastic username and password on NXLog config file?

Thanks

Hello,

Correct me if I am wrong - are you using om_elasticsearch in your setup? Have you already checked the om_elasticsearch documentation?

Thanks,
Rafal

    Hi Rafal,

    Yes using om_elasticsearch, I already test the AddHeader for sending elastic basic authentication header but seems not working

    Hi there,

    Do you get an ERROR in your /opt/nxlog/var/log/nxlog/nxlog.log similar to:

    [om_elasticsearch|elasticsearch] HTTP response status is not OK: 401 Unauthorized

    Can you try formatting the header as shown below:

    AddHeader Authorization: Basic ZWxhc3RpYzokWSRAUk1ZbmV0==

    are you able to login when using simple curl from the host running your nxlog?

    curl -vv --user elastic https://10.1.1.134:9200

    Also please try formatting the URL in your config as follows

    URL http://10.1.1.134:9200/_bulk

    Thanks,

    Konstantinos
