                                • Easily enable profiling with the integration wizard, which supports all popular servers, as well as offers the "Generic server" option for any other server
                                • Local and remote: easily profile servers running on developer machine as well as on a remote server, including production
                                • Built-in SSH tunneling support simplifies profiling in restricted network conditions
                                • Fully controllable profiling overhead

                                Local and remote profiling

                                Profile a remote application as easily as a local one:

                                • Remote EE server integration wizard enables profiling in a console mode
                                • Console attach wizard
                                • Built-in SSH tunneling support simplifies profiling in restricted network conditions

                                Controllable overhead

                                • Full control of imposed profiling overhead by using appropriate startup options and utilizing profiling modes on demand
                                • Minor overhead by default: all profiling activities which may cause noticeable overhead are off unless you explicitly turn them on
                                • EE server integration wizard suggests even stricter default limitations for production use

                                Affordable, permissive licensing

                                • Special offerings to academic and scientific use
                                • Open source project developers and maintainers may apply for a free license

                                Profiling is easy

                                Developer friendly environment

                                cf赛事竞猜2020 Profile from within your integrated development environment (IDE):

                                CPU profiling - investigate performance issues

                                • CPU usage graph showing total, kernel and garbage collector times is always available
                                • Choose from available profiling modes -- tracing, sampling, call counting -- to balance between result accuracy and fullness and profiling overhead
                                • Alternatively, estimate CPU usage retrospectively, basing on recorded thread telemetry data
                                • CPU tracing's adaptive mode automatically controls profiling overhead, user no longer needs to explicitly choose filters to exclude methods from profiling as other profilers require
                                • CPU views present results as call trees, hot spots, method lists, back traces, merged callees and callees lists
                                • High-level profiling available: SQL calls, web requests
                                • What-if feature: to concentrate on what's most important, you can exclude particular method calls from the profiling results, or focus on particular calls only
                                • Compare snapshots to see what's changed

                                Memory profiling - memory leaks, usage, GC

                                • Memory usage graphs show heap and non-heap memory pools, GC activity and, if recorded, object creation rate per-second
                                • Comprehensive heap inspection and analysis
                                • Object allocation recording to solve garbage collection and memory allocation issues. Available settings allow to balance between result fullness and profiling overhead. In particular, consider the unique object counting mode with almost zero overhead.
                                • The richest UI to analyze memory usage and find memory leaks
                                • Paths from roots to analyze memory leaks and object retention, with the ability to immediately see what would happen if particular references were excluded (i.e. to test a proposed memory leak fix effect without re-running the application)
                                • Find objects holding most memory with dominator tree and class list
                                • Dissect objects by category, on and on:
                                • Object explorer to inspect individual objects
                                • Garbage collection profiling to estimate garbage collector load, and, if garbage collection takes a significant amount of time, pin-point the problematic code
                                • Automatic inspections detect typical problems. Performing this type of analysis by hand would be a very complicated (if at all possible) task.
                                • Support of HPROF binary format snapshots and the JVM built-in heap dumper
                                • Ability to export the profiler format memory snapshots to HPROF binary format for processing with 3rd party tools
                                • Set description language to use in automated memory tests

                                Threads, monitors, exceptions

                                High-level results

                                • Event recording: in addition to low level profiling results such as method calls, the profiler can record higher level events with their essential properties such as database queries, web requests and I/O calls. Use built-in probes to recognize typical problems or write your own to inspect specifics of your particular application.
                                • Performance charts show basic and higher-level telemetry graphs of web, database, I/O activity.

                                Powerful analysis capabilities

                                • Immediately see profiling results as they come, in real time
                                • Capture a snapshot for a more sophisticated analysis, to save the results for history records, share them
                                • Compare performance or memory snapshots to see what's changed
                                • Lightweight basic telemetry graphs are always available. Very useful and unique feature is that the recent telemetry results are remembered inside the profiler agent. This allows you to connect to the profiled application on demand, being able to discover how the application behaved in the past.
                                • Automatic inspections detect typical problems. Performing this type of analysis by hand would be a very complicated (if at all possible) task.

                                Automated profiling

                                cf赛事竞猜2020 In addition to the rich UI capabilities for interactive profiling, profiling can also be conducted semi- or fully automatically.

                                • Startup options to immediately activate desired profiling modes
                                • Triggers to perform actions on events such as particular method call or a monitored value reaching its threshold
                                • Probes to execute arbitrary code on invocation of particular methods
                                • API to control profiling of this or another application: switch profiling modes and store profiling results
                                • Command line tool to perform some profiling tasks without using the UI

                                Export to external formats

                                In addition to the rich analysis capabilities of the profiler, the profiled results can be exportedcf赛事竞猜2020 to external form to process with 3rd party tools or share with those not having the profiler.

                                • export to XML, HTML, CSV, plain text or image
