Elasticsearch and Filebeat integration with Kinetic Structured Logs

Overview

In our Kinops SaaS offering we're leveraging our structured logs with Elasticsearch and Kibana to provide us with enhanced troubleshooting, analytics, and reporting capabilities. We wrote a short blog article outlining some of the quick benefits we realized after doing this.

Below are some screenshots to demonstrate some of the benefits in leveraging Elasticsearch and Kibana.

Custom dashboards for displaying activity, performance, and health in your environment.

Quickly see how long requests are taking for a specific user on average on the CE servers.

Perform queries to find errors in the logs for a specific user. Maybe providing the capability to avoid having to ask the question 'when did you experience the problem' and slowing down the investigation.


The steps below go over how to setup Elasticsearch, Filebeat, and Kibana to produce some Kibana dashboards/visualizations and allow aggregate log querying. The steps below assume you already have an Elasticsearch and Kibana environment.
 

Elasticsearch Configuration

Create an Elasticsearch index template

The following is what we use for our index template - you may need to change some settings for your Elasticsearch environment and data retention requirements. Your Elasticsearch administrator can help determine this.

PUT _template/kinetic-request
{
    "order": 0,
    "template": "kinetic-request-*",
    "settings": {
      "index": {
        "refresh_interval": "5s"
      }
    },

          }
        }
      }
    }
}

Create Elasticsearch ingestion pipelines

There are four ingestion pipelines that we created, one for each structured log. These pipelines help parse the log message into document fields inside of the indexes and allows for querying the log files by app.user, app.space, error level, response times, and more.

*Note*: The following pipelines assume you're using the default structured log format. If you've modified your %DATA_DIR%/config/log4j.xml or %DATA_DIR%/config/log4j-default.xml file for the structured log files 'ConversionPattern' then you will have to change the ingestion pipeline patterns listed below.

The highlighted sections in the Filebeat.yml sample above need to be modified to match your environment. The file paths need to be the full filesystem path to your structured log files and the hosts needs match the Elasticsearch host information for your environment.
