FAQPage Schema
How do I collect on-device performance metrics for iOS and macOS applications?▼

You can collect on-device performance metrics by utilizing the MetricKit framework to gather detailed CPU, memory, and network usage data for iOS and macOS applications. This Skill processes the resulting MXMetricPayload to help identify production bottlenecks.

How do I analyze crash diagnostics and hang call-stack trees from MetricKit?▼

To analyze crash diagnostics, this Skill processes MXDiagnosticPayload data from MetricKit to evaluate crash, hang, and disk-write diagnostics. It parses the included call-stack trees to pinpoint exact code paths causing application instability.

Does MetricKit support custom signpost metrics for monitoring specific code paths?▼

Yes, MetricKit supports custom signpost metrics. You can add custom performance intervals to track and monitor specific code paths, allowing you to measure precise execution times and optimize targeted application workflows.

What is the best way to monitor app performance in production using MetricKit?▼

The best way to monitor app performance in production is by deploying MetricKit to continuously collect on-device metrics and crash diagnostics. This Skill automates the analysis of MXMetricPayload data to improve user satisfaction.

Can I use this Skill to debug disk-write diagnostics on iOS?▼

Yes, you can use this Skill to debug disk-write diagnostics on iOS. It processes MXDiagnosticPayload data from MetricKit to analyze disk writes and other performance issues, providing insights into potential storage bottlenecks.

What are the limitations of MetricKit for diagnostic analysis?▼

MetricKit requires appropriate handling of MXMetricPayload and MXDiagnosticPayload data, and is limited to iOS and macOS applications. Proper framework integration is necessary to process the call-stack trees for effective crash diagnostics.
