I have set up the alerting in Kibana using the ElastAlert plugin. I have set up the slack integration which works well. I would like to have a custom message and use the JSON key's value but I am getting <MISSING VALUE> error when message is posted in slack.
Here is the current configuration look like for slack.
alert_subject: "User's location changed"
alert_text_type: alert_text_only
alert_text_args:
- user_name
- user_friend_count
alert_text: "{0}'s friend count increase to {1}"
barito JSON contains these 2 keys used in args but not sure what's going on.
thanks in advance.
