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 ><P > If you are using the openMosixanalyzer for looking at "online"-logfiles (current history) you can enable the "refresh"-checkbox and the view will auto-refresh. </P ><P > The load-lines are normally black. If the load increases to >75 the lines are drawn red. These values are openMosix--informations. The openMosixanalyzer gets these informations from the files /proc/hpc/nodes/[openMosix ID]/* </P ><P > The Find-out-button of each nodes calculates several useful statistic values.
