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. |
