This Hubot plugin enables various operations related to logging:

  • record all messages on configured channels to an ElasticSearch server
  • enable various commands to interact and query the logs
  • serve web pages to browse the logs
  • announce to users joining a channel where they can find the logs web page

If you only need to log to ElasticSearch, you can rather use hubot-elasticsearch-logger which only does that.

For low volume channel or for testing purpose, you can use the free service of Bonsai.io elasticsearch hosting.

Warning: This plugin is still in alpha stage. use with caution. It is designed to work fine with the hubot-irc adapter. Later on it will be tested on slack, gitter and others.


In your hubot dir:

npm install hubot-es-logger --save

Then add to your external-scripts.json

[ 'hubot-es-logger' ]


You will need to set various environment variables to get the logging configured

Variable required default description
HUBOT_BASE_URL yes the default url where your hubot web server can be reached. By default hubot launches express on port 8080
ES_LOG_ENABLED no 'false' useful to disable logging at bot start in dev env
ES_LOG_ANNOUNCE no 'false' if set, will private message to people joining the channel, signaling the url where to browse the logs
ES_LOG_ES_URL yes the url to your Elasticsearch server
ES_LOG_ROOMS yes comma-separated list of channels to log ie '#trolls,#another_channel,#third'
ES_LOG_INDEX_NAME no 'irclogs' name of the Elasticsearch index
ES_LOG_SINGLE_INDEX no 'false' if 'true', it will use only one index, but by default, one index is created per day
ES_LOG_KIBANA_URL no if you have a kibana access to your irc logs, it will be displayed on the web page
ES_LOG_KIBANA_TEMPLATE no the template used in kibana (for building the url)

Web interface

Make sure you secure your web interface appropriately (with hubot-restrict-ip or putting hubot behind a proxy).

The web interface for now only shows the last 24 hours of discussion, but it will be configurable, searchable and navigable soon in next versions.
