After SQL Server user activity is stable, this value reaches a steady state. SQL Re-Compilations Number of SQL recompiles per second. Microsoft files Navigate to the download page for Microsoft JDBC Drivers for SQL Server. All channels with this unit will be stacked on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. Note If the server cannot automatically register the SPN, the SPN must be registered manually.

Once a sensor is created, you cannot change this value. It is shown for reference purposes only. If you need to change this, please add the sensor anew. Buffer Cache Hit Ratio Percentage of pages found in the buffer cache without having to read from disk. Maintenance Begins This field is only visible if you enabled the maintenance window above. Edit Sensor Channels To change display settings, spike filter, and limits, switch to the sensor’s Overview tab and click the gear icon of a specific channel. However, if an SPN is not provided, it will be generated automatically based on the type of a client connection. This statistic is affected by all constraints (such as I/O, number of users, cache size, complexity of requests, and so on). High batch requests mean good throughput. SQL Compilations Number of SQL compilations per second. The time interval between automatic checkpoints can be highly variable. A database with a substantial transaction workload will have more frequent checkpoints than a database used primarily for read-only operations. These include, but are not limited to: To connect to the MySQL server using ODBC, you must have a Connector/ODBC driver. Analysis Services also includes Data Mining so that you can uncover the patterns and relationships hidden inside large volumes of data.

After a long period of time, the ratio moves very little. Рекомендуемые: Процессор: Intel Core i7 3000 МГц или выше; Память: 4 ГБ или более; Жесткий диск: 100 ГБ или более. Lock Requests Number of new locks and lock conversions per second requested from the lock manager. This shows the number of user connections, and the number of logins and logouts per second. The corresponding settings from the parent objects will always be active. Using Master Data Services, you create a central repository for your master data and maintain an auditable, securable record of that data as it changes over time. Generally, you can increase the buffer cache hit ratio by increasing the amount of memory available to SQL Server. Этот мастер также создает файловый сервер высокой доступности. Click on the reading-glasses and use the object selector to choose an object on which the current sensor will depend. This setting is shown for your information only and cannot be changed here.

Tags are not case sensitive. We recommend that you use the default value. For more information, see Microsoft Kerberos Configuration Manager for SQL Server. Примечание. Бесплатную версию Microsoft SQL Server 2008 R2 Express Edition можно скачать на сайте корпорации Microsoft: SQLEXPRADV_x64_RUS.exe – для 64-разрядных ОС; SQLEXPRADV_x86_RUS.exe – для 32-разрядных ОС или установки в режиме WOW64. Внимание! This setting determines where the sensor is placed in sensor lists. When a client wants to connect to a service, it locates an instance of the service, composes an SPN for that instance, connects to the service, and presents the SPN for the service to authenticate.

See the Database Connection Pooling section for details. If you are connecting to SQL Azure make sure to set the validate connections flag as SQL Azure closes inactive connections after a very short delay. Logouts Total number of logout operations started per second. Dependency Delay (Sec.) Define a time span in seconds for a dependency delay. Above this number, please consider using multiple Remote Probes for load balancing. Tags Enter one or more Tags , separated by spaces or commas.

You can set another primary channel later by clicking the pin symbol of a channel in the sensor’s Overview tab. Logins Total number of logins started per second. Maintenance Window Specify if you want to set up a one-time maintenance window. The new SPN format does not require a port number. The SPN, after it is registered, maps to the Windows account that started the SQL Server instance service. If the SPN registration has not been performed or fails, the Windows security layer cannot determine the account associated with the SPN, and Kerberos authentication will not be used. The Database Engine supports several types of checkpoints: automatic, indirect, manual, and internal. Choose from: General Statistics : Read general performance counters. Schedules, Dependencies, and Maintenance Window Inheritance for schedules, dependencies, and maintenance windows cannot be interrupted.

Deadlocks Number of lock requests per second that resulted in a deadlock. The scanning interval determines the time the sensor waits between two scans. With the period list option it is also possible to pause monitoring for a specific time span. Page Splits Number of page splits per second that occur as the result of overflowing index pages. Show channels independently (default) : Show an own graph for each channel. The KB article, How to use Kerberos authentication in SQL Server, contains information about how to grant read or write permission to an SPN for an account that is not a Domain Administrator.

The content includes end-to-end examples, code samples, and videos. NoteThe -k SQL Server advanced setup option enables a database administrator to throttle checkpoint I/O behavior based on the throughput of the I/O subsystem for some types of checkpoints. The sensor can try to re-reach and check a device several times, depending on the option you select here, before it will be set to a Down status. Internal checkpoints Internal Checkpoints are generated by various server components to guarantee that disk images match the current state of the log. ImportantLong-running, uncommitted transactions increase recovery time for all checkpoint types. Non-LTS releases have diminished support, and the database may not work at all on them. Read : Users in this group can see the object and review its monitoring results. The frequency depends on the recovery interval advanced server configuration option, which specifies the maximum time that a given server instance should use to recover a database during a system restart. Dependency This field is only visible if the Select object option is enabled above.

This helps you avoid false alarms if the monitored device has only temporary issues. Enter the WMI class name that the sensor uses for monitoring your server instance. Full : Users in this group can see the object, review its monitoring results, edit the object’s settings, and edit access rights settings. Stack channels on top of each other : Stack channels on top of each other to create a multi-channel graph. On my Windows 7 Ultimate x64 I can’t do anything with the existing instance of MS SQL Server 2008 R2. It was my mistake to uninstall some components related to SQL Server before running the main uninstaller. For other connections that support Kerberos the SPN is registered in the format MSSQLSvc// for a named instance. Automatic checkpoints are throttled based on the number of outstanding writes and whether the Database Engine detects an increase in write latency above 50 milliseconds.For more information, see Configure the recovery interval Server Configuration Option. Bringing a SQL Server failover cluster instance (FCI) offline. To change the recovery interval on a server instance To configure indirect checkpoints on a database To issue a manual checkpoint on a database See also. The sensor will influence the behavior of the device, where it is created on: If the sensor is in Down status, the device will be paused.

Use the date time picker to enter the start date and time of the maintenance window. Note MySQL Installer will install and configure Connector/NET for you. MySQL distributions for Windows can be downloaded from See Section 2.1.2, “How to Get MySQL”. MySQL for Windows is available in several distribution formats, detailed here. Set sensor to «warning» for 4 intervals, then set to «down» : Show an error status only after five continuously failed requests. This can help to avoid false alarms, for example, after a server restart, by giving systems more time for all services to start up. Microsoft SQL Server has been supported since MediaWiki 1.23, and is best supported on the LTS releases of MediaWiki. The Database Engine estimates the maximum number of log records it can process within the recovery interval. The SPN lookup fails or does not map to a correct domain account, virtual account, MSA, or built-in account, or is not a correct domain account, virtual account, MSA, or built-in account.

Local and remote connections use NTLM. Note ‘Correct’ means that the account mapped by the registered SPN is the account that the SQL Server service is running under. Windows Storage Server 2008 R2 включает в себя следующие функции и компоненты: Задачи начальной настройки (ICT): упрощают выполнение различных задач по настройке, которые должны быть выполнены поставщиком после установки Windows Storage Server 2008 R2 на устройстве хранения. Schedules can be used to monitor for a certain time span (days, hours) every week. Note You probably also installed other helpful MySQL products like MySQL Workbench and MySQL Notifier on your system. The recovery interval configuration option uses the number of transactions to determine the recovery time as opposed to indirect checkpoints which makes use of number of dirty pages. Sensors using the Windows Management Instrumentation (WMI) protocol have high impact on the system performance! However, an online transactional workload on a database configured for indirect checkpoints can experience performance degradation. A checkpoint creates a known good point from which the SQL Server Database Engine can start applying changes contained in the log during recovery after an unexpected shutdown or crash. Therefore, you will not see all setting fields in this dialog. Recovery of a database with a long-running transaction can take much longer than the specified in the recovery interval option.
