![]() ![]() 1 – Database size has grown beyond thresholdīy default the host message count in database throttling threshold is set to a value of 50,000, which will trigger a throttling condition under the following circumstances:.If the host publishes to multiple queues, the weighted average across all destination queues is computed (based on recent publish statistics) and compared with the threshold. ![]() Indicates if the destination queue depth of all message box databases exceeds the threshold. “Database connection per CPU” is the maximum number of concurrent database sessions (per CPU) allowed before throttling begins. The threshold value is controlled by the “Database connection per CPU” value in the BizTalk Host Throttling settings. 1 – Database session count exceeds threshold.Indicates if the number of currently opened database sessions exceeds the threshold. The number of concurrent MessageBox database connections being used. Since there is some overhead involved, BizTalk Server will resume gathering statistics only when there are at least 100 publishes with 5% of the total publishes within the restarted host process. If the host is restarted, statistics held in memory are lost. If a process is publishing to multiple queues, this counter reflects the weighted average of all the queues. This value is measured by the number of items in the queue tables for all hosts and the number of items in the spool and tracking tables. The number of messages in the database queues that this process has published. Each such stateless instance corresponds to a single message within the EPM. Most messaging scenarios involve stateless instances where messages are processed completely independent of each other. For example an ordered send port that maintains information about the ordering are considered stateful instances. Messages belonging to a stateful instance are co-related in some form or the other. Stateful instances are those that maintain certain state information about the messages associated with the instance. For the End Point Manager, a service instance may either correspond to a single stateless message, or to a collection of stateful messages. For the orchestration engine, a service instance refers to each running instance of an orchestration schedule. The number of service instances active in memory. Information how to change default Host Throttling settings and thresholds can be found here: (v=bts.20).aspx. This behavior is by design to prevent consuming system threads with performance monitor when throttling activities are not occurring.īizTalk Server uses in-build host throttling thresholds. The BizTalk:MessageAgent performance counters are provided for the explicit purpose of analyzing the throttling behavior of a host and therefore will not capture data unless the specified host is actively processing documents. To monitor SharePoint servers, you can also use “Internet Information Service (IIS) Services and Counters”, “Windows Server 2003-2008 Services and Counters” and “SQL Server 2005-2008 Performance” templates. Windows Administrator on the target server. This SAM application monitor template assesses the status and overall of performance of host throttling of default Microsoft BizTalk Server 2010 or 2013 installation.
