The performance analyzer displays the compiled log and illustrates where the main problems exist in the current database situation. In case of real-time monitoring, the MaxGauge is able to analyze the issues in greater details through the post-mortem analysis function.

Real Time Integrated Monitoring in Units of Seconds at No System Cost

The MaxGauge executes real-time monitoring using the SGA Memory Direct Access Method which does not use up any of the oracle resource. Even if the database is in a hang mode, it will still independently continue to monitor and collect the data. Also, our special patented feature of Multi-thread Method’s integrated monitoring screen offers you the ability to intuitively monitor multiple databases in real-time.

Powerful Diagnosis & Analysis Based on a Complete Operation Data Log (Logging  Diagnosis  Tuning)

MaxGauge collects and records all database operations with hardly any load on the system resource. The data log contains all necessary information required to analyze any system errors or performance issues. The MaxGauge Performance Analyzer allows you to intuitively recognize the precise point of performance degradation and system errors in the collected data log. As a result, it can significantly reduce the time and cost for troubleshooting.

Useful Information Sharing in On/Off-Line Mode

Provides more than 25 different frames including the Trend Chart, Active Session, SQL Elapsed Time, Lock Tree, and etc., with which the user is able to customize the main screen as desired, using the docking facility.

Active Session Wait The active session wait displays the sessions and SQL’s flowchart. The status indicators can be classified as follows: Red: 15 seconds or longer, Yellow: 10 seconds or longer, Blue: Less than 10 seconds.

Powerful System Performance Monitoring and Alert Notification Function

The MaxGauge constantly monitors the database performance status and in case a problem occurs, the user is notified through various forms and means to take quick measures to resolve the issue at hand.

Instant Problem Recognition via the Real-time Alarm MaxGauge Alert Monitor provides the alarm occurrence status with respect to the DB performance indicators, wait indicators, and OS indicators, as set in the Alert Configuration setting. The pop-up feature is also provided for a constant recognition of the alarm.

Real-time Analysis and Resolution

You can view the diagnostic analysis screen of any portion in the graph with a single click. By retrieving the information from the logging server, a real-time diagnosis can be executed without any load on the system resource, and even in case of hang-ups, it continues to collect and monitor the session information, various performance statistics (STAT), which can be useful in system status analysis. Also, the analysis of the selected period from the Trend Chart becomes linked with the Performance Analysis, which allows an immediate search and analysis.

Lock Diagnosis Function The correlation between the session owning the lock and the wait sessions, and the deadlock analysis can be easily identified in a tree structure.

Parallel Query Execution Diagnosis For a parallel query execution, one coordinator process and a several slave processes are expressed in a tree structure, which helps to easily identify the correlation.

Remote Query Diagnosis For a query using a database link, the correlation between the local session and the remote session are expressed in a tree structure, which helps to easily identify the cause of the remote query’s execution delay.

System Monitor This function monitors the database server’s resource usage and I/O in real-time, including the CPU usage, Swap I/O, Network I/O, and the disk work status. As a result, the database server can be also monitored as well.

Types of Logging Data and Collection Interval

Drill-down based on Top-down Approach

Performance Trend With MaxGauge, the user is able to analyze the root causes of performance bottlenecks in depth, because all the important clues for the performance bottleneck are captured in the log file, and these files can be analyzed repeatedly in real-time.

System Level Analysis The daily or a specific period’s trend graphs can be produced with the Performance Analyzer to identify the overall system’s performance degradation point. It also provides a function to analyze the trend of the performance data accumulated over several days.
