This section describes how to manage the nodes and services that make up a cluster.
Monitoring the Cluster
This section describes how to monitor the health and performance of a MapR cluster.
Using MapR Monitoring (Spyglass Initiative)
MapR Monitoring (part of the Spyglass initiative) provides the ability to collect, store, and view metrics and logs for nodes, services, and jobs/applications.
Log Visualization
Use dashboards to visualize the logs across multiple nodes and clusters.
Update the Elasticsearch URL for Kibana
Kibana connects to a single Elasticsearch node to read logs. In the event that Kibana is unable to read logs due to the failure of an Elasticsearch node, configure Kibana to connect to an available Elasticsearch node.

Update the Elasticsearch URL for Kibana

Kibana connects to a single Elasticsearch node to read logs. In the event that Kibana is unable to read logs due to the failure of an Elasticsearch node, configure Kibana to connect to an available Elasticsearch node.

Note: The Elasticsearch node that Kibana connects to by default is determined by the first Elasticsearch node that was specified when the cluster was configured to use MapR Monitoring

Open /opt/mapr/kibana/kibana-<version>/config/kibana.yml.
Update the elasticsearch.url parameter to point to an available Elasticsearch node.

Tip: If you want to configure Kibana to work even if the Elasticsearch node is unavailable, see the Kibana documentation for the steps to configure Kibana to load balance across multiple Elasticsearch nodes.
