Use

Note that not all columns are displayed in the default view. You can remove or add columns usingChange Layout.

The following columns are available in both the Instance-Specific Logon List and System-Wide Logon List:

Features

Column

Meaning

Client (Client)

Name of the client

User Name

Name of the user

Client Host

The client host identifies the connected client of the user.

The format of the client host depends on the type of logon. If the client is SAP GUI, the client host contains the host name of the client. If the client is HTTP, the IP address of the client is specified as the client host.

Application

Information about the current application. For example, this can be an SAP transaction code.

Dialog Time

Time of the user's last request to the system.

Session (Number of Sessions)

This field specifies the number of sessions belonging to a user.

Priority

Specifies the priority with which requests are executed for this session. If there are work process bottlenecks, a request can be displaced by another request with higher priority.

Session Type

Type of executed session.

(e.g. GUI, HTTP, HTTPS, SMTP, RFC, BGRFC Scheduler, BGRFC Unit, APC, BATCH, SYSTEM). You can find detailed information about the different session types from the F1 help in the system.

Memory (Memory Net)

Total size in kilobytes of extended memory (EM) occupied for a session, plus the memory that is visible for all internal sessions (global memory).

ConvID (Conversation ID)

Unique eight digit number identifying RFC connections.

The conversation ID can be used to find RFC connections within:

  • The gateway monitor (transaction SMGW)

  • The connection table Start of the navigation path Transaction SM51 Next navigation step Goto Next navigation step Information Next navigation step Communication Next navigation step RFC Connections End of the navigation path.

  • The developer trace

Application Info.

Additional information about the current application.

Session Key

Displays the internal key of a session.

The internal key of a session consists of three parts:

  • Logon handle: index in the logon table

  • Logon ID: unique ID of the logon

  • Session handle: internal number of the session

The session key is displayed in the form T<logon handle>_U<logon ID>_M<session handle>, (for example, T15_U234_M2

Trace (User Trace)

The status of the user trace. The statuses are On and Off (On: user trace activated / Off: user trace deactivated).

Memory (Gross)

Total size (KB) of all occupied extended segment (ES) blocks for a session, plus the memory visible for all internal sessions.

Memory (Heap)

Total size in kilobytes of heap memory occupied in the local process for a session. When heap memory local to the process is used, a session is fixed to a work process. For this reason this memory type is used only for batch and internal system tasks (e.g. batch scheduler tasks).

Memory (Hyper)

Total size of logon-specific memory in kilobytes. All sessions belonging to the logon can use this memory. Hypermemory is used to store logon-specific data (for example, logon information such as language and client) that is used by all the sessions. The value indicates the size of the memory occupied in kilobytes. For performance reasons a heap manager is also used here.

Memory (ABAP)

Size in kilobytes of the memory occupied by the ABAP-VM. This is the memory that is required by the ABAP-VM while the program to store local variables, tables, and so on is executed. Depending on the session type these memory requirements are forwarded either to the extended memory (EM) or to the local process heap manager.

Paging Blocks

Number of SAP paging blocks used.

The size of a paging block is 8 KB.

RFC Type

RFC type There is a distinction between internal RFC connections and external RFC connections:

Internal (I): Internal RFC from an application server in the same system

External (E): External RFC from another SAP system or an external client

Main Program

Name of the main program used.

Security Context Index

Internal reference to security context (time invariant)

Info Logon

Additional information about the logon type (sync. RFC: Async.RFC; RFC UI; HTTP; HTTP-UI; HTTP ITS; BATCH; SMTP; BGRFC scheduler; BGRFC unit; APC; APC UI)

You can find detailed information about the different session types from the F1 help in the system.

Tasks (Open Tasks)

Number of open tasks of the session (e.g. pending responses from RFC calls and HTTP calls).

The following column is available on in the System-Wide Logon List:

Column

Meaning

Server Name

The name of the application server is displayed here.
