PEGA0084 alert: Search node count

The PEGA0084 alert is generated when the number of available index host nodes does not meet the quorum ((replicas/2) + 1) required for index writes to succeed.

Example message text

Not enough active shards for index Work to meet write consistency of quorum.

Reason for alert

The alert can occur when some of the index nodes go down, causing the number of available index host nodes to be less than the quorum. Remove any offline index host nodes either from the Search landing page (Designer Studio > System > Settings > Search) or use RemoveIndexNode in the prpcUtils utility to reset the quorum so that the writes succeed. The status of index host nodes is displayed in the Search index host node setting section of the Search landing page. For instructions about using the prpcUtils utility to remove search index nodes, see Managing Elasticsearch index host nodes outside of the Search landing page.
