Performance/operational metrics can be managed in an integrated manner through NAVER Cloud Platform's Cloud Insight service and can be used for various monitoring purposes. Note See the [Cloud Insight API Guide](/docs/en/management-cloudinsight) for information on how to use performance/operational metrics for monitoring. ## Basic information The following is the basic information of the Search Engine Service service for using performance/operational metrics. - Product name (`prodName`) - System/Search Engine Service(VPC) - Product key (`cw_key`) - 526121220794617856 ## Performance/operation metrics The performance/operational metrics of the Search Engine Service service are as follows. - Metric | Metric name | Data type | Unit | Metric type | Description | Interval | Aggregation | | --- | --- | --- | --- | --- | --- | --- | | | index_total | LONG | num | Basic, Default | Total number of indexing operations. | Min1,Min5,Min30,Hour2,Day1 | | | index_time_in_millis | LONG | millisecond | Basic, Default | Total time in milliseconds spent performing indexing operations. | Min1,Min5,Min30,Hour2,Day1 | | | index_current | LONG | num | Basic | Number of indexing operations currently running. | Min1,Min5,Min30,Hour2,Day1 | | | index_failed | LONG | num | Basic | Number of failed indexing operations. | Min1,Min5,Min30,Hour2,Day1 | | | delete_total | LONG | num | Basic | Total number of deletion operations. | Min1,Min5,Min30,Hour2,Day1 | | | delete_time_in_millis | LONG | millisecond | Basic | Time in milliseconds spent performing deletion operations. | Min1,Min5,Min30,Hour2,Day1 | | | delete_current | LONG | num | Basic | Number of deletion operations currently running. | Min1,Min5,Min30,Hour2,Day1 | | | noop_update_total | LONG | num | Basic | Total number of noop operations. | Min1,Min5,Min30,Hour2,Day1 | | | throttle_time_in_millis | LONG | millisecond | Basic | Total time spent throttling operations. | Min1,Min5,Min30,Hour2,Day1 | | | cluster_index_total | LONG | num | Basic | Total number of indexing operations for all the nodes.
