All session monitoring requests will be directed to the current information source as displayed in the Perspective field at the top of the screen. By default this will be either your local client session when you are running in Local (non-daemon) mode or if you are running in daemon mode, monitoring requests will be directed to your coordinator daemon. Options 4 and 5 are only available if you are currently using daemon perspective, as in the example screen above.
This option can be used to route monitoring requests to any active coordinator daemon or to your local client session (see screen below).

This screen shows the memory pools that are used by jobs. The following information is provided:
| Field | Description |
|---|---|
| Pool Name |
The PRIVATE pool is allocated in the job’s private memory. Shared memory pools are always managed by a coordinator daemon. Fixed pools are named Fvrnnnnn where vr is the product version and revision level and nnnnn is the pool element size. |
| Extents | The number of extents. Performance may be improved by tuning job parameters to eliminate extents. |
| Free Memory | The amount of free memory available in all extents in the pool. |
| Free Elements | The number of free elements in the pool. |
| Type | Pool type.
O: The job created and owns the pool |

This screen shows the client sessions that are active in a job managed by the Adabas System Coordinator. The following information is provided:
| Field | Description |
|---|---|
| Session ID | The Session ID (last 8 characters only). IDs comprised of special characters are normally generated by the system. |
| Txn | The current or last Transaction ID executed (TP systems only). The value ‘*timeout’ indicates that the inactivity threshold has been reached for this client session. |
| Dormant | The amount of time since the last user activity. |
| Memory | The amount of memory allocated by the user. |
| Adabas Cmds | The number of Adabas commands executed for this user. |
| Quick Locate | The number of times the coordinator optimized command processing because two or more commands for the same user were executed consecutively. |
| Type | Indicates whether or not the user is managed by an Adabas System Coordinator daemon. A value of ‘S’ indicates that the user is managed by a Adabas System Coordinator daemon. |
PF keys can be used to sort the user list in various sequences:
| Key | Description |
|---|---|
| PF5 (SortN) | The list is sorted by User ID. |
| PF9 (SortT) | The list is sorted in descending time since the user was last active. |
| PF10 (SortU) | The list is sorted in descending order of the number of Adabas calls issued. |
| PF11 (SortO) | The list is sorted in descending order of user search optimization. This shows the number of times for each user that an index search was avoided. |
Mark a session with one of the commands shown:
D: display internal information
S: snap internal information to CORDUMP
P: purge this session. Be careful not to purge a session that is still in use as this may have unpredictable results. You must confirm the purge request with PF5:

Each Adabas System Coordinator daemon maintains a list of targets that are or were at one time active. This information is communicated to all daemons in the cluster.
When the perspective is daemon, this screen displays the network from that daemon’s perspective.
You can change the perspective to another daemon or local by pressing PF5:

The screen shows the daemons that are active in the coordinator group. This option is only available when using daemon perspective, because node information is kept in the daemon, not in the local client.
The following information is provided:

| Node | The Adabas Node ID of the coordinator daemon. |
| System | The operating system ID. |
| Start Time | The start time of the coordinator daemon. |
| Sessions | The number of client sessions currently managed by this coordinator daemon. |
| Cluster Moves | The number of client sessions that have been routed dynamically to this system, and the average session message size per move. This field is only relevant for clustered applications in a multisystem environment. |

This screen displays the IBM sysplex coupling facility cache memory statistics. The definition of each statistical value is provided on a series of detailed screens, together with a repetition of the value.
Use PF11 to display a series of detail screens. Use PF10 to return to the last screen. You can then use the same PF keys to proceed forward or backward to the desired screen.
Cache statistics are valid only if the coordinator group is defined as type “Sysplex”.
