Monitoring Data Analysis

Diagnosing performance issues or troubleshooting errors involves reviewing system-wide data, and typically begins with information captured by the Monitoring node in the Sybase Control Center Unwired Platform administration perspective. However, it can extend to any and all state and log data that is available to the administrator.

There is no rigidly defined troubleshooting path for administrators to take. Instead, data is reviewed and analyzed component by component until a comprehensive picture of the system emerges and gives the administrator enough symptoms to diagnose the problem.

As shown by the illustration below, monitoring and state data is collected on the platform at various levels to create an inverted pyramid of potential diagnositc data. Using this pyramid, an administrator can scale up and scale down in terms of the specificity of detail, depending on the issue being investigated. Subsequent scenarios in this section use this illustration to show you which diagnostic components may help you diagnose issues or errors.

• Collecting Data
  When diagnosing application errors and issues, the user need to provide some intial troubleshooting data that helps to identify which records and events captured by the Sybase Control Center monitoring tool should be more carefully analyzed for telling symptoms.
• Device Application Performance or Issue Analysis
  If a device user reports lagging performance or errors in a deployed application, there are a series of diagnostics the administrator can perform to investigate the problem.
• Access Denied Analysis
  If a user reports an access is denied error, the administrator can check the security log, and from there, validate the package's security configuration.
• Data Update Failure Analysis
  If a user reports an unreceived push notification (for replication packages only), or that data appears to be updating incorrectly, administrators should follow a similar process as documented for the device application performance analysis scenario.
