SharePoint Health Analyzer
On the Central Administration home page, click Monitoring, Health Analyzer. You can use this built-in feature to analyze and resolve problems in the following areas: security, performance, configuration, and availability. Health Analyzer rules are predefined and run at scheduled intervals, such as hourly, daily, weekly, and monthly. If an error is detected, the corresponding rule is triggered. Each rule has a brief explanation about why the error occurs and provides you with a link to a detailed article that contains step-by-step help to resolve the problem. When you follow the help process, you can re-run the rule to verify resolution. If the error does not appear in the list, the problem is resolved.
Timer Jobs
On the Central Administration home page, click Monitoring, Timer Jobs. SharePoint Server uses configurable timer jobs to collect health data and then writes the data to the logging folder and to the Logging database. The data is then used in reports to display the health status of the farm servers.
You can reschedule a timer job, enable or disable it, and run it on demand. Daily, weekly, and monthly schedules also include a window of execution. The timer service will select a random time within this interval to start running the timer job on each applicable server. This feature is appropriate for high-load jobs that run on multiple servers on the farm.
Reporting
On the Central Administration home page, click Monitoring, Reporting. This feature lets you configure diagnostic logging and data collection, and view administrative and health reports. Because some configurations will use up drive space and adversely affect system performance you must carefully plan what configurations to set.
Microsoft PowerShell
PowerShell is a powerful tool for monitoring SharePoint Server. You can run commands to obtain the exact logs that you want to view. For more information, see View diagnostic logs in SharePoint Server.
System Center – Operations Manager with System Center Management Pack for SharePoint Server
System Center – Operations Manager is a powerful monitoring platform that lets you monitor services, devices, and operations for many computers in a single console. By using Operations Manager, you can view status, health, performance information, and alerts generated for availability, performance, configuration and security situations. For more information, see Operations Manager.
To use Operations Manager to monitor SharePoint Server, you must install System Center Management Pack for SharePoint Server. You can use this tool to monitor events, collect SharePoint component-specific performance counters in one central location, and raise alerts for operator intervention as necessary. Download and install System Center Management Pack for SharePoint Server 2016.
SharePoint Developer Dashboard
This tool provides diagnostic information that can help a developer or system administrator analyze performance of SharePoint Web pages. This utility can help if a page is loading slowly, a Web Part is not performing, or if a database query on the page is not performing. The SharePoint Developer Dashboard is disabled by default. You can enable it by using PowerShell. For more information, see SharePoint Developer Dashboard.
Windows Management Instrumentation (WMI)
WMI provides many classes for you to monitor the SharePoint Server environment. For each manageable resource, there is a corresponding WMI class. For more information, see Windows Management Instrumentation (WMI) Overview.
SQL Server Reporting Services (SSRS)
SQL Server Reporting Services provides a full range of ready-to-use tools and services to help you create, deploy, and manage reports for your organization. It also has programming features that let you extend and customize reporting functionality. By using SQL Server Reporting Services, you can create interactive, tabular, graphical, or free-form reports from relational, multidimensional, or XML-based data sources. You can publish reports, schedule report processing, or access reports on-demand. You can use SQL Server Reporting Services to create reports based on predefined models, and to interactively explore data within the model. You can select from a variety of viewing formats, export reports to other applications, and subscribe to published reports. The reports that you create can be viewed over a Web-based connection or as part of a Windows application or SharePoint site. For more information, see Reporting Services (SSRS).
SharePoint Health Analyzer, Timer Jobs, Reporting, and PowerShell are built-in features, whereas System Center, System Center Management Pack for SharePoint Server 2016, and SQL Server Reporting Services are independent tools. SharePoint Developer Dashboard and WMI are built-in tools and intended for developers or system administrators. These tools are complementary and apply to different scenarios.
Administrative Actions logging
Administrative changes to SharePoint Server settings can sometimes cause errors or have unintended effects. To aid in troubleshooting administrative changes, logging around key SharePoint administrative actions is available in Feature Pack 1. Logging is available for both Central Administration and Windows PowerShell actions.
