Confusing graphs in 1.5 (build 5962)

[bbrendon]

Please tell me I'm not crazy. It took me like 5 minutes to understand this graph. Why does it have two scales? One on the right and one on the left? It only needs one!

To me it looks like swap used went from 7.6 GB to 0. When in reality it changed by a few megabytes yet there is an almost vertical line in the middle going from the top to the bottom!

Must be some of graph items scales set to left, others to right. Left scale (swap used) have only one value.. but this should be improved.

1 - It depends on the item, whether graph will have left or right scale. If 2 items on 1 Graph have both left and right - you'll see what you see.

2 - It's very likely that you're useing delta-per-sec values for your swap used. 1.5.4 containes a bug that causes those items to be calculated wrong. This bug is already fixed in the svn version of zabbix.

Thanks. Yup, it was the left/right thing.

I think what happened is the default changed from right to left, and I never used the option, so upon adding a new line to the graph, it got all weird!

Thanks!
