1.2.6 Host Viewer Tab

The Host Viewer page displays a table showing all hosts currently accessing the system.

The Host Viewer page


The table consists of:

HOST

The IP number of the host(s). When selecting the link the Pico Viewer is opened. Refer to 1.2.7 Pico Viewer Tab for further information.

CPU SYSTEM TIME (%)

The percentage of time spent in kernel specific code, such as scheduling of different processes or network transfer. 100% means that all processing power is spent.

DETAILS

A link to the Host Details page showing a table with values for the selected host. See Host Details below for more information.

Host Details

The Host Details page contains additional information about the selected host. The picture and table below describes the content of this page:

The Host Details page

CPU USER TIME (%)

The percentage of CPU time spent in non-kernel specific code. 100% means that all processing power is spent.

CPU SYSTEM TIME (%)

The percentage of time spent in kernel specific code, such as scheduling of different processes or network transfer. 100% means that all processing power is spent.

CONTEXT SWITCHES (/S)

The number of context switches per second. A context switch occurs when one process hands over information to another process. The more context switches, the less effective and scalable the system will be.

SWAPPED TO DISK (BLOCKS/S)

The amount of data that was swapped out. A large value indicates that the system does not have enough RAM to manage the memory requirements of the different processes.

SWAPPED IN FROM DISK (BLOCKS/S)

The amount of data that was swapped in from disk. A large value indicates that the system does not have enough RAM to manage the memory requirements of the different processes.

PROCESSES WAITING FOR RUN (#)

Shows how many processes that are waiting to be executed. A high number indicates that the machine is not fast enough to manage the load.

PROCESSES SWAPPED OUT (#)

Number of processes that has been persisted in swap due to shortage of available memory or due to aggressive management of the memory layer.

PROCESSES IN SLEEP (#)

Number of processes that are presently not doing anything.
