Tracked Msgs Copy (Purge Jobs)	Time in seconds for most recent run of SQL agent job which copies tracked message bodies for tracked messages.
Tracking data size	Tracks the size of the tracking data table on a particular message box on a particular server.
Tracking Spool Cleanup (Purge Jobs)	Time in seconds for the most recent run of the SQL agent job which purges the inactive tracking spool tables.

Host counters

Host Queue - Instance State Msg Refs - Length	Tracks the number of message references in the instance state queue for this particular host.
Host Queue - Length	Tracks the total number of messages in the particular host queue.
Host Queue - Number of Instances	Tracks the number of instances of this particular host.
Host Queue - Suspended Msgs - Length	Tracks the total number of suspended messages for the particular host.

Orchestration Engine Performance Counters

Its not always the standard BizTalk performance counters are used to check performance for BizTalk this is a good example where you have to combine it with other counters.

% used physical memory	Percentage used of total physical memory on the machine.
Active application domains	Number of loaded orchestration application domains in the process.
Average batch factor	Number of persistence points reached since the host instance started, divided by the number of underlying transactions.
Database transactions	Number of database transactions performed since the host instance started.
Database transactions/sec	Average number performed per second.
Dehydratable orchestrations	Number of orchestrations instances that can be dehydrated which are currently hosted by the host instance.

Dehydration cycle in progress	Indicates whether there is a dehydration cycle currently in progress.
Dehydration cycles	Number of dehydration cycles completed.
Dehydration threshold	Number in milliseconds that determines how aggressively orchestrations are being dehydrated. If the orchestration engine predicts that an instance will be dehydratable for an amount of time longer than this threshold, it will dehydrate the instance.

Transactional scopes compensated	Number of long-running or atomic scopes that have successfully completed compensation scopes since the application started.
Transactional scopes compensated/sec	Average number compensated per second.

Host Throttling Performance Counters

Active instance count	Number of service instances active in memory. For the orchestration engine, a service instance refers to each running instance of an orchestration schedule. For the End Point Manager, a service instance may either correspond to a single stateless message, or to a collection of stateful messages.
Database session	Number of concurrent MessageBox database connections being used.
Database session threshold	The current threshold for concurrent database sessions. This is initially set to the Database connections value on the Resource-Based Throttling tab in Settings Dashboard. This value is auto-tuned based on the database session usage of the process. If the number of concurrent database sessions exceeds this threshold at any time, host throttling is implemented.
Database size	Number of messages in the database queues that this process has published. 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. If a process is publishing to multiple queues, this counter reflects the weighted average of all the queues.
High database session	0: Normal 1: Database session count exceeds threshold
High database size	0: Normal 1: Database size has grown beyond threshold
High in-process message count	0: Normal 1: In-process message count exceeds limit
High message delivery rate	0: Normal 1: Message delivery rate exceeds the message processing Rate
High message publishing rate	0: Normal 1: Publishing request rate exceeds completion rate
High process memory	0: Normal 1: Process memory exceeds threshold
High system memory	0: Normal 1: System memory exceeds threshold
	0: Normal 1: Thread count exceeds threshold
In-process message count	Number of in-memory messages delivered to the XLANG engine or the outbound messaging engine that are not yet processed.
In-process message count threshold	The current threshold for in-process message count.
Message delivery delay (ms)	The current delay in ms imposed on each message delivery batch (applicable if the message delivery is being throttled).
Message delivery incoming rate	Number of messages per second that are being delivered to the Orchestration engine or the Messaging engine in the given sample interval.
Message delivery outgoing rate	Number of messages per second that are being processed by the Orchestration engine or the Messaging engine in the given sample interval.
Message delivery throttling state	0: Not throttling 1: Throttling due to imbalanced message delivery rate (input rate exceeds output rate) 3: Throttling due to high in-process message count 4: Throttling due to process memory pressure 5: Throttling due to system memory pressure 9: Throttling due to high thread count 10: Throttling due to user override on delivery
Message delivery throttling state duration	Seconds since the system entered this state. If the host is throttling, how long it has been throttling; if it is not throttling, how long since throttling was applied.
Message delivery throttling user override	0: No override 1: Always throttle message delivery 2: Do not throttle message delivery
Message publishing delay (ms)	The current delay in ms imposed on each message publishing batch (applicable if the message publishing is being throttled and if the batch is not exempted from throttling).
Message publishing incoming rate	Number of messages per second that are being sent to the database for publishing in the given sample interval.
Message publishing outgoing rate	Number of messages per second that are actually published in the database in the given sample interval.
Message publishing throttling state	0: Not throttling 2: Throttling due to imbalanced message publishing rate (input rate exceeds output rate) 4: Throttling due to process memory pressure 5: Throttling due to system memory pressure 6: Throttling due to database growth 8: Throttling due to high session count 9: Throttling due to high thread count 11: Throttling due to user override on publishing
Message publishing throttling state duration	Seconds since the system entered this state. If the host is throttling, how long it has been throttling; if it is not throttling, how long since throttling was applied.
Message publishing throttling user override	This counter reflects the user override that is monitored by the engine and interpreted as follows: 0: No override 1: Always throttle message publishing 2: Do not throttle message publishing
Physical memory usage (MB)	The amount of physical memory in MB being used on the machine by all processes.
Process memory usage (MB)	The process memory consumption in MB. This is the maximum of the process’s working set size and the total space allocated for the page file for the process.
Process memory usage threshold (MB)	The current threshold for process memory consumption in MB. This is initially set to the Process virtual value in Settings Dashboard. If a percentage value is specified, it is computed based on the available memory to commit
Service class ID	The decimal value of the initial part of the service class GUID that this performance counter instance corresponds to. A process may host more than one service class and the message agent performance counters show the data for the most active service class.
Thread count	Number of threads being used within the process.
Thread count threshold	The current threshold for the number of threads in the process. This is initially set to the Threads value on the Resource-Based Throttling tab in Settings Dashboard. This value is auto-tuned depending on the thread requirements of the current process. If the number of threads in the process exceeds this threshold value at any point in time, host throttling is implemented.
Total batches committed	Number of database batches that the service class has committed.
Total messages delivered	Number of outbound messages delivered to the Orchestration engine or the End Point Manager (EPM).
Total messages published	Number of messages published.
