Metrics for SolarWinds Observability entities

Many of the collected metrics from SolarWinds Observability entities are displayed as widgets in SolarWinds Observability explorers; additional metrics may be collected and available in the Metrics Explorer. You can also create an alert for when an entity's metric value moves out of a specific range. See Entities in SolarWinds Observability for information about entity types in SolarWinds Observability.

Common metrics

The following metric(s) are available for all entities in SolarWinds Observability.

Metric Units Description
sw.metrics.healthscore Percent (%)

Health score. A health score provides real-time insight into the overall health and performance of your monitored entities. The health score is calculated based on anomalies detected for the entity, alerts triggered for the entity's metrics, and the status of the entity. The health score is displayed as a single numerical value that ranges from a Good (70-100) to Moderate (40-69) to Bad (0-39) distinction.

To view the health score separately for each specific entity type in the Metrics Explorer, group the sw.metrics.healthscore metric by entity_types.

APM/service metrics

Metrics for service entities are sent by APM libraries installed and configured to monitor your service. See Application performance monitoring (APM) for more information.

The satisfactory load time, tolerating, and frustrated load times are defined when creating the website entity. For more information about the Apdex standard, Defining the Application Performance Index.

If the response time for requests takes less time than the satisfied load time threshold set for your website, the Apdex score is considered a satisfied load time. It is a tolerating load time if the response time takes up to four times the satisfied load time threshold, and a frustrated load time if it takes longer than four times the satisfied load time threshold.

Largest Contentful Paint. A measurement of how quickly the largest image or text content of a web page is loaded.

Largest contentful paint time is considered good if loading the largest image or text block takes less than 2.5 seconds, needs improvement if it takes up to 4.0 seconds, and poor if it takes longer than 4.0 seconds.
rum.web_vitals.cumulative_layout_shift  

Cumulative Layout Shift. Measures how much a webpage shifts unexpectedly while a user is viewing the webpage. A shift may occur if content loads at different speeds or if elements are added to the website dynamically.

A cumulative layout shift value of less than .1 is considered good, a value up to .25 needs improvement, and a value greater than .25 is poor.
rum.web_vitals.first_input_delay seconds (s)

First Input Delay. Time from when a user first interacts with your site to the time when the browser is able to respond to the interaction. First input delay (FID) helps measure the first impression a user has of your site's responsiveness.

The FID is considered good if responding to a customer’s first interaction with the site takes less than 100ms, needs improvement if it takes up to 300 ms, and poor if it takes longer than 300 ms.
