Algorius Net Viewer Manual | Monitoring Log
Algorius Net Viewer keeps a Monitoring log. Logging modes are set up separately for local maps and for each server. The log contains results of devices scanning. The records are stored in a database and viewed using Monitoring reports.
Monitoring log keeps detailed data for 3 hours enabling the detailed immediate log for all devices with Full logging level. It allows to display detailed operational monitoring log.
The monitoring log in Algorius Net Viewer allows keeping statistics for each hour and day. Records for each device and each scanning method are automatically and hourly grouped. Only those records are grouped where device didn’t change its state and error code. E.g. if a device was always on during one hour and was scanned each minute, one record will persist in database instead of 60. Thus database size can be decreased 60 times. And the less records you have, the faster reports are generated. Similarly, records can be grouped daily. This allows further reducing the size of the database. The information as to which records should be grouped hourly, and which daily, is set in the logging settings.
Statistics data are taken each hour – number of scans, min and max value etc. Thus you can quickly generate accurate reports and charts.
Records are grouped before being added into the database for the purposes of statistical logging. It decreases database load significantly.
Only numeric values of monitoring results are sent to monitoring log. String values are stored in application memory only and are displayed if you point a mouse over a device.
Data in monitoring log are indexed by map and by device. It further enhances report generation speed per map and especially per device.
Algorius Net Viewer allows you to maintain an operative monitoring log. The data in this log is stored in RAM. The device scanning results for the specified number of hours are saved.
The operative monitoring log data is used in the device hint window and in the notification:
- In the device hint window, the operative log data is used to build monitoring diagrams. The chart is dynamically updated and displays current real-time data.
- In the notification, the operational monitoring log data is used to calculate the duration of the monitoring values in the specified range. See Configuring Event for more information.
Logging modes are set up separately for local maps and for each server. To access logging settings, go to app or server options and select Logging:
The following parameters are available:
- Enable monitoring log — enables the Monitoring Log. In case you don’t need this function, you can disable it to save some disk space and decrease the processor load. It’s also recommended to disable monitoring log in case your security policy doesn’t allow it.
- Optimize to hourly/daily stats — when you add entries, which are older than the specified number of days, in the monitoring log, they will be converted to statistical information. See Monitoring Log for more information.
- Enable inventory log — enables the Inventory Performing Log. In case you don’t need this function, you can disable it to save some disk space and decrease the processor load.
- Enable Web access log — enables the Web access log. In case you don’t need this function, you can disable it to save some disk space and decrease the processor load.
- Keep records for the specified number of days — when enabled, Algorius Net Viewer will automatically remove all records older then the number of days defined here. This saves space in the database and speeds up report generating by reducing the number of processed records. This option is applied only for enabled logs.
- Enable Operative monitoring log – when turned on, the operative monitoring log is maintained for the specified number of hours.
To clear the monitoring log, select Monitoring→Clear Log from the main window menu. The monitoring log records will be deleted. Cleaning is performed in the background and may take some time.
You can also set the program to automatically remove old log records. See Logging configuration for more information.
