Google provides two metrics for monitoring the
The number of shards of the
DeployedIndex. As data is added and deleted, Matching Engine automatically reshards the index to achieve optimal performance. This metric indicates the current number of shards of the deployed index.
The total number of active replica servers being used by the
DeployedIndex. To match query volume, Matching Engine automatically turns up or down replica servers based on the minimum and maximum replica settings specified when deploying the index.
If the index has multiple shards, each shard can be served by using a different number of replica servers. This metric is the total number of replica servers across all shards of the given index.
