Collecting node health and indexing status scores
Steps to configure node health options, and commands to retrieve health and indexing scores.
Node health options are always enabled for all nodes. Node health is a score-based representation of how fit a node is to handle search queries.
- A higher score indicates better node health. 1 is the highest score.
- A lower score applies to nodes that have a large number of dropped mutations and nodes that are just started.
On DSE Search nodes, the shard selection algorithm uses account proximity and secondary factors such as active and indexing statuses.
You can examine node health scores and indexing status. The indexing status is INDEXING, FINISHED, or FAILED.Replication selection for distributed Solr queries can be configured to consider node health when multiple candidates exist for a particular token range. This health-based routing enables a trade-off between index consistency and query throughput. When the primary concern is performance, do not enable health-based routing.
