Summary > System Dashboard
IWSVA provides dynamic displays where you can view the "real-time” statistics of the IWSVA server.
Also, above the left menu on every page, IWSVA provides a "smart search" field where users can enter a feature name and be directed to the appropriate page for that feature.
Note: Role-based access rights are not breached by the "smart search" feature.
Threshold Alert Settings
Threshold Alert Notifications
Note: If the system time is adjusted backward (either manually or through automatic network time server synchronization), IWSVA stops gathering real-time statistical information. To have IWSVA collect real-time statistical information, you must restart the metric management daemon. Type the following commands: /etc/iscan/S99ISMetricMgmtd stop /etc/iscan/S99ISMetricMgmtd start
Component Update Status Display
This is a static display that shows the current version of IWSVA components (such as the scanning engine and virus pattern) and the dates that they were last updated. To manually update the components, click Update to display the Manual Update screen. See Manual Update for more information.
Hard Drive Display
This is a static display that shows the status of the disk(s) used by IWSVA for its system files, quarantine space, temporary space, and logs. If the database resides on the same drive as any of these directories, then the database disk usage is also included in the display. The scale along the Y-axis varies according to the data being presented (for example, from 0 to 100%).
You can specify threshold alert values and the frequency of alerts so that you are notified when any of the hard disk statuses reach a critical level. IWSVA can send these alerts either through email, SNMP trap/notification (if enabled), or both.
You cannot configure the display values in IWSVA, but you can edit the disk locations in the /etc/iscan/intscan.ini file.
Bandwidth Usage Display
This is a dynamic display that shows the bandwidth usage of both inbound and outbound traffic for HTTP(S) and FTP. IWSVA translates traffic in terms of requests and responses. Therefore, the display interprets all requests as outbound traffic and all responses as inbound traffic. From this display, you can view any potential bandwidth problems. The mapping is reversed for the reverse proxy mode.
The display shows ten data points, which gives the graph a history of five to ten minutes of activity. This activity is only monitored for the local IWSVA server. With the ideal refresh rate being between 30 and 60 seconds, the display has a default refresh rate of 30 seconds.
Clicking the 1-day or 30-day button opens a window that shows a static chart with one or 30 days of usage, respectively. IWSVA retrieves this information from the database. If the database does not contain enough data, then the display shows only the available data.
You can specify threshold alert values and the frequency of alerts so that you are notified when a bandwidth usage reaches a critical level. IWSVA can send alerts either through email, SNMP trap/notification (if enabled), or both.
Note: The bandwidth setting should be very high—above ”out of normal range” values to avoid frequent alerts.
Concurrent Connections
This is a dynamic display that can have two graphs: one for FTP and the other for HTTP(S). For FTP, the connection measured is the session for both commands and data. For HTTP(S), the connection measured is the session for both requests and responses. The default refresh rate is 30 seconds. Both the X and Y axis scales are variable. The X axis scale is determined by the set refresh rate and the Y axis scale is determined by the number of concurrent connections at a given time.
CPU Usage Display
This is a dynamic display that shows CPU utilization on the local system. For multiple CPUs, the display shows the average IWSVA usage across all CPUs. It does this by displaying a single line for all CPU utilization. IWSVA determines the CPU utilization based on the CPU cycles used, the CPU cycles used by IWSVA, and the total CPU cycles used by the backend, CPU-monitoring API.
By default, IWSVA samples the CPU usage each second for two minutes, giving you 120 data points. You cannot configure the display values in IWSVA, but you can edit the refresh rate in the /etc/iscan/intscan.ini file.
Clicking the 1-day or 30-day button opens a window that shows a static chart with one or 30 days of CPU usage, respectively. IWSVA retrieves this information from the database. If the database does not contain enough data, then the display shows the data that is available.
Physical Memory Usage Display
This is a dynamic display that shows the amount of physical memory used by the local IWSVA machine.
By default, IWSVA samples the physical memory usage each second for two minutes, giving you 120 data points. You cannot configure the display values in IWSVA, but you can edit the refresh rate in the /etc/iscan/intscan.ini file.
Clicking the 1-day or 30-day button opens a window that shows a static chart with one or 30 days of physical memory usage, respectively. IWSVA retrieves this information from the database. If the database does not contain enough data, then the display shows the data that is available.
