Application Monitoring metrics

This topic describes metrics commonly used in Application Monitoring, a sub-service of the Application Real-Time Monitoring Service (ARMS). You can use them to build custom Grafana dashboards and PromQL queries.

Important

If your application is ingested through Managed Service for OpenTelemetry, only business metrics are available. JVM metrics, system metrics, and other categories are not supported.

Business metrics

Common dimensions

Dimension name	Dimension key
Service name	service
Service PID	pid
Host IP	serverIp
Interface	rpc

Metric list

The following metrics apply to every access type. In queries, replace $callType with the actual access type. For the list of access types, see Service access types and available dimensions.

For example, to query HTTP request counts, change arms_$callType_requests_count to arms_http_requests_count.

Metric name	Metric	Metric type	Collection interval	Unit	Dimensions
Request count	arms_$callType_requests_count	Gauge	15 seconds	None	Different service access types have different dimensions. For details, see Service access types and available dimensions.
Failed request count	arms_$callType_requests_error_count	Gauge	15 seconds	None
Request latency	arms_$callType_requests_seconds	Gauge	15 seconds	Seconds
Slow request count	arms_$callType_requests_slow_count	Gauge	15 seconds	None
Request latency quantiles	arms_$callType_requests_latency_seconds	Summary	15 seconds	Seconds	Available only when the access type is HTTP and quantile statistics are enabled. To turn them on, see Advanced settings. Quantile dimensions: 0.5 0.75 0.90 0.99

Note

Except for quantile metrics, the metrics above are Gauge types: each point is the cumulative value over the collection interval, which differs from typical open-source metrics. For example, to estimate a 1-minute average QPS, use ARMS PromQL such as sum_over_time(arms_$callType_requests_count[1m])/60, whereas open-source frameworks often use rate(http_server_requests_count[1m]).

Metric storage

Business metrics are stored in the detailed metric store (metricstore-apm-metrics-detail).

Aggregated business metrics

Because each call type uses its own metric name, PromQL can become very long when one application uses multiple call types (for example, both HTTP and Dubbo).
Business metrics retain full observation dimensions, but some analytics scenarios do not need every dimension. Querying raw business metrics can be slow in those cases.

To address these issues, ARMS provides aggregated business metrics.

Metric description

Aggregated business metrics fall into these categories:

General
Records request count, failed request count, slow request count, and average request latency across all access types.
Database types
Same as General, scoped to database access types.
SQL
Same metrics as the database category, with an additional SQL dimension.
Exception
Records request count and average request latency when exceptions occur across all access types.
Status code
Records request count per HTTP status code.
Quantile
Records request latency quantiles across all access types.

Except for the quantile category, each category offers two metric shapes: a standard aggregate whose name ends with xxx_raw, and a reduced-dimension variant named xxx_ign_x_y, where x and y are dimensions rolled up (omitted from the metric series).

Metric type and collection interval

Unless otherwise noted, aggregated business metrics are Gauge metrics with a collection interval of 15 seconds.

Common dimensions

Every aggregated metric includes the following dimensions:

Dimensions	Description
pid	Application PID
service	Application name
serverIp	Instance IP
source	Metric source: apm Applications monitored with Application Monitoring. xtrace Applications ingested through Managed Service for OpenTelemetry. ebpf Applications monitored with Application Monitoring eBPF Edition.

Usage example

Choose a metric when using PromQL to sum requests across all interfaces of an application

You need a metric that exposes per-interface request counts. The General category in this topic satisfies that requirement.
If you only need the interface dimension—and not upstream interfaces, upstream applications, or remote hosts—choose a metric that keeps the interface dimension while omitting as many other dimensions as possible.

In practice, arms_app_requests_count_ign_destid_endpoint_parent_ppid_prpc is a good choice.

Metric storage

Metrics stored in the core metric store (metricstore-apm-metrics):

arms_app_requests_{metric}_ign_destid_endpoint_parent_ppid_prpc_rpc
arms_app_requests_{metric}_ign_destid_endpoint_rpc_prpc
arms_app_requests_{metric}_ign_destid_endpoint_parent_ppid_prpc

The remaining aggregate business metrics are stored in the detailed metric store (metricstore-apm-metrics-detail).

JVM metrics

Common dimensions

Dimension name	Dimension key
Service name	service
Service PID	pid
Host IP	serverIp

Metric list

Metric name	Metric	Metric type	Collection interval	Unit	Dimensions
GC count (cumulative)	arms_jvm_gc_total	Counter	15 seconds	None	Gen GC occurrence area: Young：young generation Old: old age Cause GC triggering reason (agent version 4.4.0 and later): System.gc(), Heap Dump Initiated GC, Allocation Failure, etc. Expand to view detailed description of Cause GC System.gc(): When the program explicitly calls`System.gc()`This cause is triggered when garbage collection is requested. FullGCAlot/ScavengeAlot: These causes may be related to testing or debugging scenarios where frequent full GC or small GC ("scavenge") are triggered intentionally. Allocation Profiler: This garbage collection reason may involve memory allocation profiling to better understand memory usage. JvmtiEnv ForceGarbageCollection: Indicates that the Java Virtual Machine Tool Interface (JVMTI) issued a request to force garbage collection. Heap Inspection Initiated GC & Heap Dump Initiated GC: These are generally not routine operations but are used to inspect the heap or take a heap dump. WhiteBox Initiated Young/Full GC & Run to Breakpoint: These are triggered by WhiteBox tests and are usually used for JVM internal testing purposes. No GC: The JVM may trigger GC based on internal heuristics (such as heap usage trend prediction in the CMS algorithm) rather than specific conditions (such as insufficient memory), so it is displayed as No GC. Allocation Failure: A garbage collection triggered because the JVM cannot allocate memory for a new object, indicating a possible memory pressure situation. CodeCache GC Threshold/Aggressive: Involves code cache, which stores compiled code. GC may be triggered when the cache reaches a certain threshold or requires active management. Metadata GC Threshold/Clear Soft References: GC triggered by metadata space thresholds or soft reference clearing can release memory without affecting application execution. G1 Evacuation Pause / Compaction Pause / Humongous Allocation / Periodic Collection: These are specific GC reasons related to G1 garbage collector, which is optimized for low pause times. Diagnostic Command: Triggered by a diagnostic command, usually used for internal monitoring or diagnostic purposes. Shenandoah GC Causes: These are related to the Shenandoah garbage collector, which is designed to reduce pause times through concurrent operations. Z Garbage Collector Causes (Timer, Warmup, etc.): These are specific to ZGC (Z Garbage Collector) and focus on performance tuning aspects such as warm-up, allocation rates, and proactive measures. ILLEGAL VALUE: Indicates an illegal or unrecognized garbage collection cause value, as a protection against unexpected situations.
