Diagnostic plans
Basic
$200/mo. ANNUAL
Diagnose common performance issues.
Resolve common website slowdowns with Hang diagnostics.
Diagnostics: Hangs.
Diagnose and resolve common performance issues that affect your website health.
Website hangs
Automatically diagnose website hangs and performance degradation due to dozens of common performance issues.
Once diagnosed, your team can use detailed diagnostic reports to determine the cause of the hangs down to specific application code.
Hang diagnostics
LeanSentry automatically detects website hangs, and diagnoses them to determine their cause.
A developer on your team can use the diagnostic reports to determine the cause of each hang, down to code.
The hang diagnostic identifies dozens of conditions that cause hangs and performance degradation. It then pinpoints the specific locations in your application code that triggered them, so you can definitively resolve the right issue.
Professional
$499/mo. ANNUAL

Performance analysis
Get full-spectrum diagnostics to identify and resolve most production issues quickly.
Go beyond reactive troubleshooting, and use the comprehensive performance analysis to eliminate performance bottlenecks before they become issues.
Slow request diagnostics
In addition to full website hangs, LeanSentry also tracks how many requests to your website were slow.
See which of your important URLs had slow requests, and use the diagnostics to determine where in your application code the slowdowns occurred.
LeanSentry automatically diagnoses slowdowns in top URLs on your site. You can also enable slow request diagnostics for specific URLs where you are having issues.
The slow request diagnostic can identify where the slowdown is in your application code, and may provide additional details such as SQL queries or remote service call urls.
CPU diagnostics
Under increased traffic, applications can experience CPU overload or performance degradation/queueing due to an overloaded processor.
LeanSentry will automatically diagnose CPU overloads. You can then use the diagnostic reports to identify specific pathways in application code that cause it.
Use the CPU diagnostic reports to visually drill into the specific code pathways responsible for the overload, and discover the low hanging fruit to optimize in your code.
Memory diagnostics
Use Memory diagnostics to find application memory leaks, reduce application memory usage, and alleviate the performance impact of garbage collection.
LeanSentry can analyze your application's native and .NET memory, down to application objects, and help you understand how to properly apply memory optimization strategies based on the generational layout of objects.
A developer on your team can then use the diagnostic reports to explore the application's memeory usage, and identify low hanging fruit to optimize.
Crash diagnostics
Crashes can cause instability in production, and can be very difficult to diagnose with regular APM tools because the worker process is abruptly terminated, aborting requests, losing state, and potentially corrupting data.
LeanSentry can provide full crash diagnostics due to being outside of your application.
You can use the crash diagnostic reports to identify the root cause of the crash, so it can be corrected quickly.
Debug production errors NEW
Some production errors can be difficult to reproduce, making fixing them a fruitless exercise in guesswork.
LeanSentry allows you to capture a dump of any production application exception, letting your developers debug and fix it like they would a locally reproducable error.
Once LeanSentry captures an exception dump, your developer can download it and debug it locally in Visual Studio or another debugger of their choice.
Performance analysis
Proactively improve application performance with comprehensive performance analysis based on proven IIS and .NET best-practices.
LeanSentry analyses your application's production performance on dozens of key IIS and .NET performance categories. It then identifies specific bottlenecks in your application code, that you can address to improve application efficiency.
Each performance analysis rule identifies the cause of bottleneck, and identifies specific opportunities in your application code where improvements can be made (where applicable).
You can then use these recommendations to proactively improve application performance.

Trial
Use LeanSentry Lite on your servers risk free with our 7 day free trial. We'll ask you for payment information when you activate the plan.
During the trial, all data and insights are available, but diagnostics show limited information. Upgrade to access full diagnostic information.
Diagnostic plans
The Lite plan is an great way to get started with LeanSentry, in order to identify the issues affecting your applications.
However, the true power of LeanSentry comes from its just-in-time diagnostics, that can automatically identify the root causes of most issues down to the application code.
You can use one of the diagnostic plans to access the full diagnostics for issues LeanSentry identifies in your applications.
Most plans are limited to monitoring 1 environment only. If you have multiple application environments, or need to accomodate a development/operations team with individual user accounts, permissions, and notification preferences, please consider the Business plan.
How we calculate active servers
We charge you the base rate for the number of servers on your plan at the beginning of each month.
When you add additional servers, we'll calculate the number of additional servers in use on a daily basis and include those charges on your next month's bill.
A server is only counted on each day if it has actively provided data.
Plan changes and cancellation
You can upgrade most plans at any time, with the change being immediately effective. Downgrades to plans become effective at the end of your current plan's billing cycle, or at the end of your plan term for annual plans.
To cancel a monthly plan, simply email us at any time. Your cancellation will be effective for the next calendar month. Please note that the base plan rate is billed each month until the account is cancelled, even if your servers are no longer being monitored.
Data deletion. When the account is cancelled, all environment data is deleted and any pending statements are charged.
Annual plan. For annual plans, cancellation incurs a 3 month penalty, or the number of months remaining in your annual term, whichever is less.
