Tamr supports the following systems monitoring and alerting tools.

• Kibana
• Grafana
• Prometheus
• Elasticsearch Exporter
• Prometheus Node Exporter
• Postgres Exporter
• Spark Exporter (via Graphite)

The following diagram shows which tools are used for collecting metrics and time series data in Tamr.

Note: Kibana and Grafana are disabled by default. Their variables in the Tamr configuration are set as follows: TAMR_ELK_ENABLED=false and TAMR_GRAFANA_ENABLED=false. To enable either of them, set each variable to true. See Configuration Variables.

Before getting started with each of the following components, review the requirements.

Kibana

• Kibana is an open source data visualization plugin for Elasticsearch.
• It allows you to search and analize Elasticsearch log messages and time series data.
• Kibana is included in the Tamr package and, if you enable it, is available at port 5601.

To use Kibana for Tamr Elasticsearch Logs:

1. Confirm the requirements and set TAMR_ELK_ENABLED=true. See Configuration Variables.
2. In a browser, navigate to the default Kibana port 5601.

The following screenshot illustrates searching Tamr logs in in Kibana:

Grafana

Grafana allows you to query, visualize, alert on and understand metrics stored in Prometheus.

To Use Grafana for Tamr Logs:

1. Confirm the requirements and set TAMR_GRAFANA_ENABLED=true. See Configuration Variables.
2. Open the default Grafana port 31101 and log into Grafana using the administrator credentials.

Prometheus

Prometheus stores time series data for a specific metric and provides a query language that allows you to select and aggregate time series data in real time.

• The list of metrics that help you measure the behavior of critical components in your production environment.
• Examples of useful queries on time series data in Prometheus.
