SSH Browser (Revision #66)

SSH Browser

Aqua Data Studio 11.0 features an SSH Browser that provides an overview of your Unix based Servers. The purpose of the SSH is to help you visualize and maintain your SSH Server. The SSH Browser in Aqua Data Studio v11.0 makes uses of procfs (or the proc filesystem), a special filesystem in UNIX-like operating systems that presents information about processes and other system information in a hierarchical file-like structure, providing a more convenient and standardized method for dynamically accessing process data held in the kernel than traditional tracing methods or direct access to kernel memory. Typically, it is mapped to a mount point named /proc at boot time. You can quickly view server version information, including: OS, CPUs, Memory, Disks, File Systems, Network Interfaces and the different Users. Currently this feature is not  supported in MAC OSX, but would be added in a future release.

The following different components of the Server can be quickly viewed: 

• OS
• CPUs
• Memory
• Disks
• File Systems
• Network Interfaces
• Users

OS

 The OS node displays the Hostname, Operating System, Kernel Name, Kernel Release, Kernel Version, Machine Hardware Name and Version Signature of the Linux Server.

CPUs

 Each processor core within a system is displayed under CPUs as a tree node. The first node in the list ("cpu" without a number next to it) displays aggregate statistics of all numbered CPU nodes (cpu0, cpu1, cpu2, etc.). A dual-core processor will have two numbered CPU nodes, a quad-core processor contains four, a hexa-core processor contains six.  The screenshot above is a dual quad-core system with a total of 8 cores.

Memory

The memory node displays the Memory information and the Swap space. The total memory, free memory, memory used, memory buffers, cached memory, memory user used, total swap space, free swap space and used swap space are the information that is displayed.

Disks

Under Disks, the SSH Browser displays the hard disk information of the Server. Details displayed are Partition Name, number of blocks, minor number and major number.

File Systems

The FileSystem information is displayed under this node. The SSH Browser displays the mounts of the different File System in the Server.  Other information displayed are the total space, used space and available space in the system.

Network Interfaces

The network information are displayed under Network Interfaces. The received and transmitted packets and bytes passing through the network, errors, packets dropped, FIFO buffer errors, packet framing errors, compressed packets and multicast frames are captured under this node.

Users

The different users of the system are displayed under this node.
