41. Reports » Servers

Click on a server name anywhere in the user interface to open a tab containing server-specific information. This tab includes a few sub-tabs located at the lower side of the window. Every sub-tab shares the following common toolbar fields:

Servers – Select the servers that interest you, or select All. Administrators can restrict the servers available to guest accounts
Time Range – Select a predefined time range, or select Custom… to enter a specific time interval

41.1. Console / Server Dashboard

Allows you to group the most relevant server-related data. The configuration for this dashboard does not apply to a particular server, so the changes you make will be visible for other server dashboards as well. The operation of dashboards is described in the Reports » Dashboards chapter.

The configuration of Server and Console widgets is described in the following paragraphs.

41.2. Console / Server Graphs

Server Graphs allows you to generate various histograms for the selected server(s):

Data Units – Select one or more data units:
Most Used – Frequently-used data units
System Load – Load reported by the Linux kernel for a 5 minute period
Free RAM – Available RAM. Swap memory is not counted
Database/Graphs/SSD/Flow Collector/Packet Dumps Disk - Free space – How much disk space is available for each file-system path
Uptime – Uptime of the operating system
CPU% system/userspace/niced/idle – Percentages of CPU resources used by the system, userspace processes, processes running with increased (nice) priority, and idle loop
Number of processes – Total number of processes that are running
Hardware/Software CPU Interrupts – CPU interrupts made by hardware and software events
Context Switches – Indicates how much time the system spends on multi-tasking
Running Components – Sensor and Filter instances
Clock Delta – Difference of time between the selected server and the Console server, in seconds. If the value is not zero, run ntpd to keep the clock synchronized on all servers
Database/Graphs/SSD/Packet Dumps/Flow Collector Disk - Total – How much disk space is allocated for the partitions that store the paths
Database/Graphs/SSD/Packet Dumps/Flow Collector Disk - Free Inodes – Free inodes held by the partitions that store the paths
Database/Graphs/SSD/Packet Dumps/Flow Collector Disk - Ops/s – Reads and writes made on the partitions that store the paths
Database/Graphs/SSD/Packet Dumps/Flow Collector Disk - Bytes/s – Bytes/s on the partitions that store the paths
Server Interface(s) - Packets/Bits/Errors/Dropped – Interface statistics collected for the network interfaces defined in the Configuration » Servers chapter
Size – Select a predefined graph dimension or enter a custom one in a “<X> x <Y>” format, where <X> and <Y> are the X-axis and Y-axis pixels
Title – Graphs can have an automatically-generated title for the Auto option or title for the None option, or you can enter your own text to be rendered as a title
Legend – Select the level of detail for the graph legend
Consolidation – If you are interested in spikes, choose the MAXIMUM aggregation type. If you are interested in average values, choose AVERAGE. If you are interested in low values, choose the MINIMUM aggregation type
Servers – Generate a single graph for the selected servers
Server Interfaces – Generate a single graph for the network interfaces of the selected servers
Servers – Shows the summed up, stacked values for the selected servers

41.3. Console Events

This sub-tab is visible only when opening the Console tab. It lists events generated by Console.

41.4. Server Events

Lists events generated by the selected server(s).

41.5. Server Commands

Console administrators can execute shell commands on the selected server(s) and see the output in the browser. The commands are executed by the WANsupervisor service with the “andrisoft” user’s privileges. To prevent the execution of CLI commands via Console, start the WANsupervisor service with the “-n” option.
