Description Raghavendra Bhat 2010-02-18 13:56:55 UTC

In the Resource monitor tab, in the memory usage column it shows the percentage of the total memory being used. It may lead to confusion as the user does not nknow the RAM of the servers.
Ex: if one server has 2GB of RAM and the other server has 8GB of RAM,and both the servers are using 1GB of RAM due to some operations being performed. Then the memory column of one server shows memory usage as 50% and the other servers memory column says 12.5%. Thus a user may think that one server is using larger amount of memory. Hence the total RAM value should be displayed and the amount being used should also be displayed.

One more thing is , in the graph of the resource monitor it shows (week3,week4,week5,week6) in the X-axis of the plot generated for "per month".It should be corrected as tweek3,week4,week1(next month),week2(nex month) something like that.

This is still valid as we still don't show percentages of RAM presnet in "Resource Monitor" right its just a number. 

Other than that the "rrd" stuff is invalid.

On mouse over, RAM size is shown to the user.

Comment 3 Harshavardhana 2010-03-25 04:03:09 UTC

Raghavendra came up with this bug due to systems where RAM sizes were different by hovering the mouse over two servers namely

1. 1GB used with 2GB ram size when calculating percentages it would be 50% used. 
2. 1GB used with 10GB ram size when calculating percentages it would be 10% used. 

Now these will be shown as 50 and 10 subsequently when person hovers a mouse over the value. This is unusual and bad as we are not trying to infer anything to user.

It needs to be inferred to user that so much amount of total ram size of <size>GB is used. User might get confused at first that thinking his one of the servers is utilizing lot of RAM.

mouse hover shows used and free memory
