If TMG keeps this at or near 0, you should scale out. Available worker threads should never remain near 0 for any length of time. This monitor shows the number of firewall service worker threads that are available or waiting in the completion port queue. This monitor shows the number of active User Datagram Protocol (UDP) connections.įirewall Service: Available Worker Threads Connections pending, or not yet established, are counted elsewhere. This monitor shows the number of active TCP connections currently passing data. By comparing this counter at both peak and off-peak times, you can construct a good picture of routine usage. Use this counter to monitor general performance. This monitor shows the number of active sessions for the firewall service. This value should be as high as possible. This monitor shows the percentage of DNS domain names serviced by the DNS cache from the total of all DNS entries that have been retrieved by the firewall service. This monitor shows the rate at which URLs are stored to the cache. This monitor shows the amount of fetches from the memory cache in proportion to the total fetches from the cache. An I/O failure occurs when TMG fails to read from or write to the disk cache. This monitor shows the number of I/O failures, per second, since the firewall service started. This monitor returns the number of H.323 calls that are currently active. Use this to monitor general security threats and performance. This monitor shows the number of TCP and UDP connections created, per second. This monitor shows the number of allowed and denied packets, per second. If numbers are large (more than 100), check for network configuration errors and attacks. Use this to monitor general security threats. This monitor shows the number of packets that were denied each second. Use this counter to monitor general performance.įirewall Packet Engine: Dropped Packets/sec Each byte is counted twice once when it enters the firewall, and once when it leaves the firewall. This monitor shows the total throughput, in bytes per second, passing through the firewall. This monitor shows the total number of active connections currently passing data. This service provides the Active Directory LDS instance.įirewall Packet Engine: Active Connections This monitor returns the CPU and memory usage of the ISASTGCTRL service. This service provides Forefront Threat Management Gateway configuration storage. This monitor returns the CPU and memory usage of the Microsoft Forefront TMG Storage service. This service Controls Forefront Threat Management Gateway managed services. This monitor returns the CPU and memory usage of the Microsoft Forefront TMG Managed Control service. Service: Microsoft Forefront TMG Managed Control This service runs Forefront Threat Management Gateway jobs according to specified job schedules. This monitor returns the CPU and memory usage of the Microsoft Forefront TMG Job Scheduler service. Service: Microsoft Forefront TMG Job Scheduler This service provides Forefront TMG internet access protection services. This monitor returns the CPU and memory usage of the Microsoft Forefront TMG Firewall service. Service: Microsoft Forefront TMG Firewall This service controls Forefront Threat Management Gateway services. This monitor returns the CPU and memory usage of the Microsoft Forefront TMG Control service. SAM API Poller templates are also available.Ĭomponents without predetermined threshold values have guidance such as "use the lowest threshold possible" or "use the highest threshold possible" to help you find a threshold appropriate for your application.

On the Forefront server in the Forefront TGM snap-in, you will need to allow monitoring performance counters and services from the Orion server with the following parameters in the Firewall Policy menu. This template assesses the status and overall performance of a Microsoft Forefront Threat Management Gateway 2010 by using performance counters and windows service monitors.
