Monitor architecture

The Monitor collects metrics and performance data from SQL Anywhere databases (including those read-only scale-out and mirroring systems), MobiLink servers, MobiLink server farms, and Relay Server farms running on other computers, while a separate computer accesses the Monitor via a browser.

The Monitor collects metrics and performance data from the databases and MobiLink servers running on other computers, while a separate computer accesses the Monitor via a browser.

The Monitor is a Flash-based application that is served to a web browser via the SQL Anywhere built-in HTTP server. You interact with the Monitor through its browser interface.

There are two editions of the Monitor:

SQL Anywhere Monitor Developer Edition The Monitor Developer Edition is intended for development and testing use. It is installed by default with SQL Anywhere and it uses the installed SQL Anywhere on the back-end.
SQL Anywhere Monitor Production Edition The Production Edition is intended for deployment and production use. It is installed separately, runs as a service, and includes a fully-contained SQL Anywhere installation. This edition is only available for certain editions of SQL Anywhere. See SQL Anywhere Monitor in a production environment.

Requirements

For the computer where the Monitor is installed
- To run the SQL Anywhere Monitor on a Windows system that has the Windows Firewall enabled, you must add a port exception for port 4950.
- The SQL Anywhere Monitor reserves 384 MB of virtual address space when you start the Monitor. When you start the Monitor on Linux, you must ensure that you have least this amount of virtual space available.
- To monitor resources that are secured using ECC encryption or FIPS-certified encryption, you need a separate license. See Monitor communications security.
- The Monitor can run on the same computer as the resources it is monitoring, but it is recommended, particularly in production environments, that you run the Monitor on a different computer to minimize the impact on the database server, the MobiLink server, the Relay Server farm or other applications.
- It is recommended in production environments that you run the Monitor Production Edition. See SQL Anywhere Monitor in a production environment.
- When running the Monitor Developer Edition, you must have SQL Anywhere 12.0.0 or later installed. The Monitor Developer Edition uses the installed SQL Anywhere on the back-end.
For the computer accessing the Monitor
- Install the latest version of Adobe Flash Player that is available for your operating system. The Monitor is backward compatible with version 10 of Adobe Flash Player. To determine the correct version, see http://www.adobe.com/products/flashplayer/systemreqs/.
- Enable JavaScript in your browser.
- Ensure that the computer where you are using a browser to access the Monitor is connected to the network where the Monitor is installed.
  
  You can access the Monitor from the same computer as it is running on, but it is recommended, particularly in production environments, that you access the Monitor from a different computer.

Limitations

You can use the Monitor to collect metrics about the following versions of SQL Anywhere databases, MobiLink servers, MobiLink server farms, and Relay Server farms:
- SQL Anywhere 10.0.0, 10.0.1, 11.0.0, 11.0.1, 12.0.0, 12.0.1
- MobiLink 11.0.0 with at least the first EBF applied, 11.0.1, 12.0.0, and 12.0.1
- Relay Server 12.0.0, and 12.0.1
You can only run one edition of the Monitor on a computer at a time.
On Linux, the Monitor Developer Edition can only be run by the user who installed it.
On Linux, only the user with administrator privilege can install and run the Monitor Production Edition.
The monitor connects to SQL Anywhere databases over TCP/IP. To monitor a database running on the local database server (dbeng12), start the database server with the -x all or -x tcpip option.
You cannot use the Monitor to optimize queries or determine the speed of your application. If you are interested in tuning database and application performance, you can use such tools as the Application Profiling Wizard, the Sybase Central Performance Monitor, or the Windows Performance Monitor.
The Monitor does not provide information about individual synchronizations. For detailed information about individual synchronizations, including timing and other per-synchronization statistics, use the MobiLink Monitor. See MobiLink Monitor.
