OpenSearch:CloudMonitor alerts

Last Updated:Jul 17, 2026

OpenSearch integrates with CloudMonitor to monitor key application metrics such as storage capacity, compute resources, and query QPS. You can track application usage and configure alert rules for specific metrics.

Metrics

Parameter

Description

DocSizebyApp

The total storage capacity in use.

DocSizeRatiobyApp

The percentage of storage capacity used relative to the document quota.

DocCountbyApp

The total number of documents.

QPSbyApp

The number of queries per second.

LossQPSbyApp

The number of throttled queries per second.

LatencybyApp

The time taken for a single query.

ComputeResourcebyApp

The number of compute units used per second for queries.

ComputeResourceRatiobyApp

The percentage of compute units used per second for queries, relative to the quota.

ComputeCostbyApp

The compute units consumed per query.

DailyPeakComputeResourcebyApp

The daily peak of compute units used for queries.

App Batch Import Throughput

The number of bytes read from the data source per second during a full import.

App Batch Read TPS

The number of documents read from the data source per second during a full import.

App Batch Write TPS

The number of documents written to the engine per second during a full import, after data processing (such as join or plug-in processing).

App Real-time Input Throughput

The number of bytes read from a data source or API per second.

App Real-time Trigger Latency

The current update latency for secondary table data.

App Real-time Write Latency

The current update latency for primary table data.

App Real-time Read TPS

The number of documents read from a data source or API per second.

App Real-time Write TPS

The number of documents written to the engine per second during real-time synchronization, after data processing (such as join or plug-in processing).

App Secondary Table Trigger TPS

The number of primary table documents updated per second, triggered by changes in the secondary table. For example, if one record in a secondary table is updated per second and the primary-to-secondary table ratio is 3:1, up to three primary table documents might be updated.

App Real-time Push Throttling QPS

The number of application push requests throttled per second.

View CloudMonitor metrics

  1. Log on to the OpenSearch console. In the upper-left corner, select OpenSearch High-performance Search Edition. On the instance management page, click details.

  2. In the upper-right corner, click CloudMonitor to view the current usage of your application.

  3. The CloudMonitor page:

Enable Initiative Alert

By default, Initiative Alert is pre-configured with four metrics: DocSizeRatiobyApp, ComputeResourceRatiobyApp, LossQPSbyApp, and App Real-time Write Latency. To enable this feature:

  1. Log on to the OpenSearch console. In the upper-left corner, select OpenSearch High-performance Search Edition to go to the instance management page. Click Initiative Alert. (Alternatively, you can log on directly to the CloudMonitor console and skip to Step 3.)

  2. If the status for Initiative Alert is Disabled, click the Enable Now button. (If the status is Enabled, no action is required.)

  3. On the CloudMonitor page, click Alerts and then Initiative Alert. Find OpenSearch in the list and turn on the switch. (Click the expand icon to view and configure individual alert items.)
