LeanSentry collects complex information about your server and applications, and simplifies it to make monitoring and troubleshooting easy + fast.
This article will show you all the basics of the LeanSentry dashboard you'll need to become an expert at monitoring your environment.
1. When you log in, select the monitoring environment that you'd like to view.
You can have as many environments as you want, for example your "Production", "Staging", and "Admin" environments. Each environment represents a group of servers and applications being monitored by one or more LeanSentry Monitoring services.
On the environment dashboard, you can view all your web applications and servers at a glance, and pick one to dive deeper.
2. Application heath dashboard.
The Health dashboard shows you the application performance at a glance. Here you can see the overall performance of your application, see every slow/sluggish/failed request over time, and view application alerts.
3. Navigating the dashboard: Urls, Errors, Servers, Alerts, Performance.
LeanSentry shows you the key application health and performance information by breaking it up by:
1. Urls: The application performance broken down by important URLs. Here you can select a specific URL to inspect its performance in detail.
2. Errors: Track all the errors in the application across all the servers and URLs, identify important errors, and select a specific error to inspect it in detail.
3. Servers: Review server utilization, whether any servers were overloaded, and select a server to diagnose its resource utilization in detail.
4. Alerts: See all alerts in the application, and pick an alert to review its impact and diagnose its causes.
5. Performance: See a performance-centric view of the application, see application resource usage, track slow SQL queries and outbound HTTP requests, and diagnose causes of slow requests.
4. Selecting the time period.
LeanSentry provides a high resolution historical record of application performance, letting you go from a month down to a 10 second interval on any page.
You can always select both the current time period (which becomes the main focus of the page), as well as the comparison time period that serves as the change and comparison point.
You can specify the time period on any page in two ways:
1. Using the time context. The time context gives you a variety of options for selecting a time period.
2. By selecting on any chart. Just click-drag to select an interesting time period on any chart, and click "Apply" to zoom the entire page into it.
5. Using insights.
Instead of overwhelming you with many charts and graphs that dont show interesting information, LeanSentry packages most of the information into insights. Insights are compact sentences that highlight interesting information about your environment.
If an insight has relevant data, you can expand it to see the detailed data that supports it. If not, the insight will often be hidden to avoid wasting your time.
