> With the openMosixanalyzer you can have a non-stop openMosix-history of your cluster.
|
|
The history log-files created by openMosixcollector are displayed in a graphically way
|
|
so that you have a long-time overview what happened and happens on your cluster.
|
|
The openMosixanalyzer can analyze the current "online" logfiles but you can also open older backups
|
|
of your openMosixcollector history logs by the filemenu.
|
|
The logfiles are placed in /tmp/openmosixcollector/* (the backups in /tmp/openmosixcollector[date]/*)
|
|
and you have to open only the main history file "cluster" to take a look at older load-informations.
|
|
(the [date] in the backup directories for the log-files is the date the history is saved)
|
|
The start time is displayed on the top and you have a full-day view in the openMosixanalyzer (12 h). </P
|

from the files /proc/hpc/nodes/[openMosix ID]/* </P
|

|
|
> The Find-out-button of each nodes calculates several useful statistic values.
|

Clicking it will open a small new window in which you get the average load- and mem values
|

and some more statically and dynamic informations about the specific node or the whole cluster. </P
