Configuring IW Monitor Database Settings

Defining Hard Disk Storage Capacity and Overwrite Cycle Period for the IW Monitor Statistics Database

Procedure

Step 1

Click Settings in the top right corner.

The database settings page is shown.

Step 2

Set the MAXIMUM DATABASE SIZE value manually.

The IW Monitor periodically checks the historical data is within this defined maximum database value.

Important

 

The allocated hard disk space cannot be less than the amount of currently occupied hard disk space or more than the hard disk's total capacity.

Note

 

If the amount of network statistics data currently stored on the hard disk reaches the specified value but is recorded over less than the time specified by the TIME THRESHOLD value, the IW Monitor will overwrite the old data with the new data in real-time.

It is highly recommended that you use a hard disk of at least 100 GB capacity for network statistics storage. If you must use a hard disk of less than 100 GB capacity, assign no more than 75% of the drive’s free capacity to network statistics storage. IW Monitor may encounter performance issues if you assign more than this amount.

Step 3

Set the TIME THRESHOLD value manually.

The time threshold shows the time period for which network statistics are recorded before the old statistics data is overwritten.

Note

 

The minimum amount of time-related network-statistics data that can be stored before overwrite is one hour, and the maximum amount of time-related data that can be stored before overwrite is 90 days.

Backing up the IW Monitor Statistics Database

Procedure

Step 1

Click Settings in the top right corner.

The database settings page is shown.

Step 2

In the BACKUP DATABASE, click Backup.

A confirmation pop-up appears.

Step 3

In the pop-up, click Backup.

Step 4

After successful backup, click Download to download the backup to your computer.

Deleting the recent IW Monitor Statistics Data

You can manually delete the oldest statistics and event data in the IW Monitor database if you feel that excessive amounts of network statistics data are being written to the hard disk in short periods of time.

Important

It is strongly recommended that you back up the database before you delete the statistics data. If the current network statistics record is deleted, it cannot be retrieved. For more information on how to back up, see Backing up the IW Monitor Statistics Database.

Procedure

Step 1

Click Settings in the top right corner.

The database settings page is shown.

Step 2

Click Delete history.

A confirmation pop-up appears.

Step 3

In the pop-up, click Clean history.

Note

 

The network statistics data is only deleted if the amount of stored data exceeds the thresholds set by the MAXIMUM DATABASE SIZE and/or the TIME THRESHOLD. In this case, the oldest 10% of the currently stored network statistics data will be deleted.
