StrongLoop Alpha

Gain visibility into the performance of Node and APIs in production Starting at $0/mo.

Easy Installation

No hooks to write into your code. Just require the strong-agent module and your app is ready to report.

Node.js specific metrics

We write node. This gives us insight into node specific metrics. Native event-loop monitoring, heap profiling, and CPU profiling to name a few.

Heap Profiler

Detect memory management issues

Heap allocation for object types Instance counts of objects in memory Analyze multiple GC cycles

StatsD Integration

Integrate with third-party graphical consoles

Generate and send metrics to your own console StatsD powered interface Log API for metrics


Detect slow endpoints and transaction flow

HTTP requests broken down by % and paths External calls Slowest endpoints and databases

Heap Dumps

Diagnose fatal memory leaks

Programmed or triggered heap dumps Timed and threshold-based heap snapshots Analysis with Chrome Dev Tools

CPU Profiler

Detect application hotspots and processor bottlenecks

Collects CPU profiles of a node application during time ranger CPU cycle time spent in each JavaScript or method call Full call stack up to line of code pointing at each method invocation Visual graphing for hotspots and mouse over

Performance Monitoring

Application performance visibility

EventLoop monitoring GC, CPU and Memory usage stats Concurrency and load metrics Response times across tiers Detailed end-point system visibility

API Server Integration

Integrates well with the StrongLoop API Server
