    In addition, monitor performance of system components such as WISKI distributed service manager automated import and export of time series data processes via KiIOsys the file preprocessing optimizer KiRolling, or downloads from the SODA telemetry server.

    Logs from actions associated with the components listed above are also searchable.

    Administrators can use a flexible filter to explore more than log types and components over a period of time or on a specific date. All messages, shown to end-users, during in the selected time range will be displayed.

    The “Daily Overview” tab further breaks down hourly performance.

    System Analytics

    The command line program, initiated by Windows Scheduler, aids system administrators in conducting long-term WISKI system performance monitoring.

    This program operates even if the WISKI server is offline. Continual system monitoring data it collects can be analyzed within KISTERS web dashboards or third-party software like Zabbix.

    Similar to web dashboards for the Process Analytics application, system administrators can drill down to see processes that compromise system performance. They can investigate any unexpected server shutdown.

    Red lines in the screen shot reveal a significant amount of queuing during calculations and imports lasting longer than expected.

    The “Metrics List” tab allows administrators to choose specific time-series and graph their performance or compared them.
