Improved Monitoring and

Supportability




Filter to hide idle sessions, as well as sessions originating in the Administration editor or other

applications in the SAP HANA studio

It is now possible to hide different session types from the Threads, Sessions, and Blocked Transactions tabs. Each option can

be selected from the drop-down menu Hide Sessions.

If an option is selected, a new SQL statement is executed to display only the filtered rows. This filter does not only operate at

the display level. When an option is selected, the database is queried again for the relevant sessions.




Easier navigation between the Threads, Sessions, and Blocked Transactions tabs

It is now possible to navigate between the Threads, Sessions, and Blocked Transactions tabs by using the connection ID. This

functionality is available from the context menu (Navigate To).

On the Threads tab, it is possible to navigate from/to callee/caller by using the thread ID.

On the Sessions tab, it is possible to navigate to the connection that is blocking the selected connection.

The application information (name and user) that is available on the Threads, Sessions and Blocked Transactions tabs can

also be used to open a pre-configured dialog for the SQL, performance, and expensive statement traces.




The Threads summary section shows how many

threads are active, and how many are active with type

SQLExecutor / JobWorker.

The Sessions summary section shows how many

sessions are active, how many users are connected,

and the user type.

New summary section on Threads and Sessions tabs




For additional lock information, 3 new columns are available on the Threads tab:

Lock Wait Name

Lock Wait Component

Lock Owner Thread ID



New options to collect diagnosis information

The SAP HANA studio supports new options to collect diagnosis information (fullSystemInfoDump.py)

Collect diagnosis information from the last N days.

Create a runtime environment dump file and collect it (rtedump generated and zipped).



New monitoring editors – Memory Overview

The new Memory

Overview editor provides

a detailed graphical

breakdown of the

following main categories

of memory usage:

Physical memory

SAP HANA database

Table data

Database

management

Other information

regarding the current size

of used resources can be

seen on the Overview tab

of the Administration

editor.



New monitoring editors – Resource Utilization

The new Resource

Utilization Statistics

editor enables you to

visualize and explore the

usage history of the

following key system

resources:

CPU

Memory

Disk

The editor can help to

analyze bottlenecks,

identify patterns, and

forecast requirements.

The editor can be

opened via the context-

menu of the specific SAP

HANA system.



New monitoring editors – Memory Allocation Statistics 1/2

The new Memory Allocation Statistics editor enables you to visualize and explore

the memory allocation of every service.

In the Administration editor, choose the Landscape > Services tab. Right-click the service whose

allocation history you want to investigate and choose Memory Allocation Statistics The following information

is displayed in screen

areas identified above: 1. The components of the

selected service listed in

descending order of current

used memory (default)

2. Current breakdown of SAP

HANA used memory

displayed as a pie chart

3. Allocators of the selected

component listed in

descending order of current

used inclusive memory

(default)

4. Current breakdown of

memory usage of the 10

highest consuming allocators

displayed as a pie chart

3 4



New monitoring editors – Memory Allocation Statistics 2/2

Analyze the used memory history of the

component and its allocators by enabling the

history graph (Show Graph) and exploring the

data.

Several options are available, for example:

To change the visualized time period, adjust the From/To

values.

To visualize the memory usage of individual allocators over

the same time period as the selected component, simply

select them in the allocators table.

To see time-specific values, move the mouse over the

graph.

To see the visualized values in table format, choose (Show

history data in a table)



New summary section on Alerts tab

The summary header on the Alerts tab shows the total number of current alerts by priority and the

corresponding list of alerts

Previous Alerts Tab New Alerts Tab



Enhanced trace configuration

In the Trace Configuration dialog for the Database, User-

Specific, and End-to End Traces, conflicts between different

configuration layers are indicated with an information icon

and mouse-over text.



Additional monitoring and supportability features

Sampling session monitor – accessed via system table M_SERVICE_THREAD_SAMPLES

Provides thread sampling data to allow historic workload analysis on several granularities like application, user, statement

Improved statistics server historization

Application information added to historized blocked transactions

New table M_SQL_CLIENT_NETWORK_IO captures client network I/O statistics

Elapsed time on client side including send, server execution and receive

Execution time on server side

Time when message was received on server side and start of execution

Size of messages received on server and client side

In-memory capturing of expensive statements

The ring buffer for M_EXPENSIVE_STATEMENTS is per default active and replaces the former trace files

Two new parameters were implemented in global.ini under the section expensive_statements

Additional Features



System replication configuration wizard enhancements

It is now possible to stop the original primary system after takeover, or to start the

secondary system after registration


Additional Features

Statistics Service – New implementation design

The new statistics service design leads to performance and flexibility improvements

The statistics server is the component of the SAP HANA database that provides internal monitoring functions.

It continuously collects information about system status, performance, and resource usage, and issues alerts

in the event of problems. As of SPS 07, it is possible to switch to a new mechanism whereby data collection

and alerting are implemented through the execution of SQLScript procedures. This has the following

advantages:

The statistics server component is no longer required. By replacing the statistics server with internal procedure calls, overall

system performance is improved with reduced disk usage, memory usage, and data transfer.

The statisticsserver.ini properties file is no longer required to contain all configuration information relating to data collection and

alerting. Instead this information is contained in new tables in the _SYS_STATISTICS schema. This increases the overall

flexibility with which data collection and alerting can be configured. For example, data collectors and checks can be scheduled

more flexibly, new collectors and checks can be added more easily, and data collectors and checks can be deactivated.

For more information about how to migrate to the new mechanism after an upgrade, see SAP Note 1917938


Additional Features

Statistics service – additional lock statistics

The statistics service now collects information about lock statistics into the following tables:

HOST_OBJECT_LOCK_STATISTICS

HOST_OBJECT_LOCKS

HOST_RECORD_LOCKS

The table HOST_BLOCKED_TRANSACTIONS has been enhanced to include connection and application information.


New user logoff and logon feature with configurable startup behavior

The user can logoff actively from an SAP HANA system via the context menu. Every connection (JDBC/HTTP) is closed after the

user executes the Log Off on a selected system (1). If no connection is established, the context menu provides the possibility to

logon to a system or delete it (2). The start-up behavior of the SAP HANA studio can be configured. Under Windows >

Preferences the user can decide to restore the logged-on/logged-off status of systems on startup (3).

Additional Features

SAP HANA system logoff and logon

New feature that allows users to connect efficiently to multiple SAP HANA systems

A centrally-stored archive of SAP HANA systems is an efficient way to deploy system information to all users of the SAP HANA

studio. It avoids users having to obtain the connection details of all systems individually and then having to add them all

individually.

One user can manage the list of all systems in a centrally-accessible archive (via File > Export > SAP HANA > Landscape)

Other users can then simply link to this archive (read-only mode)

1. In the context menu of the Systems view,

choose Add System Archive Link.

Additional Features

Link to centrally-stored archive of SAP HANA systems

2. Specify the link details:

a) Link name

b) Path to the system archive containing the

system information

c) Optional: A folder in the SAP HANA

Systems view

3. Choose Finish.
