27. 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
27.1. 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.
27.2. 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● Grouping• Servers – Generate a single graph for the selected servers• Server Interfaces – Generate a single graph for the network interfaces of the selected servers● Stacking• Servers – Shows the summed up, stacked values for the selected servers
27.3. Console Events¶
This sub-tab is visible only when opening the Console tab. It lists events generated by Console.
27.5. 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.
