Server Logging
Logging occurs both:
q Within the platform
q In the underlying web / application server
q In the underlying OS
Panopticon Real Time logs are written to the Tomcat logs folder.
The logging level can be set from:
q Error – Only Errors are logged (the Default)
q Info – Operational logging is enabled including logging of data queries.
q Finest – All possible debugging logging is enabled.
Typically, when support issues are raised the user is requested to change the logging level to INFO, which additionally records:
q Data Plugin (Visualization and Data Connector) Initialization
q Data Cache Initialization
q Data Subscriptions
q Data Queries including:
· Database connection settings
· Database SQL query
· Number of rows & columns retrieved, and response time
Data query logging capabilities are specific to each data connector, with the most detailed logging available for the Database and kdb+ connectors.
Panopticon Real Time logging and auditing capabilities include Java JMX counters for usage and load monitoring, and additional logging around secured access to workbooks.
