FTP Service Object

The FTP Service performance object consists of counters that show data about the Internet Information Services FTP service.

Counter Name Description Counter Type
Bytes Received/sec Shows the rate at which data bytes are received by the FTP service at the application layer. This value does not include protocol headers or control bytes associated with the data received. Bytes Received/sec is a subset of FTP Service\Bytes Total/sec. PERF_COUNTER_BULK_COUNT
Bytes Sent/sec Shows the rate at which data bytes are sent by the FTP service at the application layer. This value does not include protocol headers or control bytes associated with the data sent. Bytes Sent/sec is a subset of FTP Service\Bytes Total/sec. PERF_COUNTER_BULK_COUNT
Bytes Total/sec Shows the rate at which data bytes are sent and received by the FTP service at the application layer. This value does not include protocol headers or control bytes associated with the data transmitted. Bytes Total/sec is the sum of the values of FTP Service\Bytes Sent/sec and FTP Service\Bytes Received/sec. PERF_COUNTER_BULK_COUNT
Current Anonymous Users Shows the number of anonymous connections to the FTP service noted during the most recent observation. Anonymous connections are connections whose requests either did not contain a user name and password or whose user name and password were ignored because authentication is not permitted on the server. If anonymous connections are not permitted on the server, the value of Current Anonymous Users is zero. Current Anonymous Users shows successful connections only. If a client request for an anonymous connection is rejected and the client responds with valid authenticating data, the connection is counted as nonanonymous. The value of this counter might not reflect the exact number of connections: when System Monitor observed the counter value, new connections might not yet have been entered, and closed connections might not yet have been deleted. PERF_COUNTER_RAWCOUNT
Current Connections Shows the number of connections to the FTP service noted during the most recent observation. The value of this counter might not reflect the exact number of connections: when System Monitor observed the counter value, new connections might not yet have been entered, and closed connections might not yet have been deleted. PERF_COUNTER_RAWCOUNT
Current NonAnonymous Users Shows the number of nonanonymous connections to the FTP service noted during the most recent observation. Nonanonymous connections are connections whose requests contain a valid user name and password, or other authentication that is required by a custom authentication scheme. If authentication is not enabled on the server, and none of the applications that run on the server request or require authentication, the value of Current NonAnonymous Users is zero. Current NonAnonymous Users shows successful connections only. If a client request for an anonymous connection is rejected and the client responds with valid authenticating data, the connection is counted as nonanonymous. The value of this counter might not reflect the exact number of connections: when System Monitor observed the counter value, new connections might not yet have been entered, and closed connections might not yet have been deleted. PERF_COUNTER_RAWCOUNT
Maximum Anonymous Users Shows the largest number of anonymous connections to the FTP service maintained simultaneously since the FTP service was started. The value of this counter might not reflect the exact number of connections: when System Monitor observed the counter value, new connections might not yet have been entered, and closed connections might not yet have been deleted. PERF_COUNTER_RAWCOUNT
Maximum Connections Shows the largest number of connections to the FTP service simultaneously maintained since the FTP service started. The value of this counter might not reflect the exact number of connections: when System Monitor observed the counter value, new connections might not yet have been entered, and closed connections might not yet have been deleted. PERF_COUNTER_RAWCOUNT
Maximum NonAnonymous Users Shows the largest number of nonanonymous connections to the FTP service maintained simultaneously since the FTP service was started. Maximum NonAnonymous Users shows successful connections only. If a client request for an anonymous connection is rejected and the client responds with valid authenticating data, the connection is counted as nonanonymous. The value of this counter might not reflect the exact number of connections: when System Monitor observed the counter value, new connections might not yet have been entered, and closed connections might not yet have been deleted. PERF_COUNTER_RAWCOUNT
Total Anonymous Users Shows the number of anonymous connections to the FTP service that have been established since the FTP service was started. Total Anonymous Users shows successful connections only. If a client request for an anonymous connection is rejected and the client responds with valid authenticating data, the connection is counted as nonanonymous. The value of this counter might not reflect the exact number of connections: when System Monitor observed the counter value, new connections might not yet have been entered, and closed connections might not yet have been deleted. PERF_COUNTER_RAWCOUNT
Total Connection Attempts Shows the total number of connections to the FTP service that have been established since the service was started. The value of this counter either remains the same or increases over time. This value does not include failed attempts to connect to the FTP server. To monitor all connection attempts, use the Connection counters on the TCP performance object. To monitor the number of connections to the FTP server that are currently active, use the FTP Service\ Current Connections counter. PERF_COUNTER_RAWCOUNT
Total Files Received Shows the total number of files received by the FTP service since the service was started. Total Files Received is a subset of FTP Service\Total Files Transferred. PERF_COUNTER_RAWCOUNT
Total Files Sent Shows the total number of files sent by the FTP service since the service was started. Total Files Sent is a subset of the FTP Service\Total Files Transferred counter. PERF_COUNTER_RAWCOUNT
Total Files Transferred Shows the total number of files transmitted by the FTP service since the service was started. Files Total is the sum of the values of FTP Service\Total Files Sent and FTP Service\Total Files Received. PERF_COUNTER_RAWCOUNT
Total Logon Attempts Shows the total number of times a user logged on successfully to the FTP service since the service was started. This counter is incremented when a connection satisfies the criteria for logging on to FTP, such as providing user authentication requirements. The FTP service supports clear-text logon authentication. The value of Total Logon Attempts does not include failed attempts to log on to the FTP service. However, the value of FTP Service\Total Logon Attempts is a subset of the value of FTP Service\Total Connection Attempts. Failed logon attempts (situations where clients were able to connect but not to log on) can be calculated by subtracting the value of Total Logon Attempts from the value of Total Connection Attempts. PERF_COUNTER_RAWCOUNT
Total NonAnonymous Users Shows the number of nonanonymous connections to the FTP service that have been established since the FTP service was started. Total NonAnonymous Users shows successful connections only. If a client request for an anonymous connection is rejected and the client responds with valid authenticating data, the connection is counted as nonanonymous. The value of this counter might not reflect the exact number of connections: when System Monitor observed the counter value, new connections might not yet have been entered, and closed connections might not yet have been deleted.
