Viewing index host node status
You can see whether your index host nodes are offline or online by viewing the index host node status on the Search landing page.
Finding the index host node status is useful when a PEGA0084 - Search node count alert occurs. This 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 required for index writes to succeed. To fix this problem, use the node status to determine which offline index host nodes to remove to reset the quorum so that the writes succeed.
In the header of Dev Studio, click.
In the Settings section, under Search index host node setting, view the list of nodes and statuses.
