Monitor II sessions

There are three types of Monitor II report sessions:

ISPF session (page The ISPF session)
Start this session with the command:
```
RMF
```
This leads to the RMF™ Primary menu, where you select 2 to start the Monitor II ISPF session.
TSO/E session (page The TSO/E session)
Start this session with the TSO/E command:
```
RMFMON
```
Background session (page The background session)
To start a Monitor II background session when all options are to be taken from the program defaults, issue the command:
```
MODIFY RMF,START AB
```

ISPF sessions and TSO/E sessions are also referred to as Display sessions, in contrast to background session.

You can obtain a printout of a Monitor II report:

during a display session
during or at the end of a background session

You can get the same reports in all sessions using a similar syntax:

Display session
You call the reports using commands that conform to TSO/E syntax rules:

Example: ASD T,A

In an ISPF session, you can also select the reports from a menu.
Background session
You call the reports using options that conform to option syntax rules:

Example: ASD(T,A)

Note: Starting with z/OS V1.2 RMF, there is no longer a local 3270 display session. However, you can have access to Monitor II reports without an active TSO/TCAS subsystem by means of the RMF Client/Server Enabling (RMFCS); see RMF Client/Server enabling (RMFCS).
