Inexplicable green line towards the top of graphs

[Ross]

Binary package hint: munin

Ubuntu 10.04 LTS
Munin 1.4.4-1ubuntu1

Towards the top of a couple graphs, "Disk usage in percent" (plugin df) and "Inode usage in percent" (plugin df_infode), there is a thin green line at the ~92% point. As can be seen in the images attached to this report, the tables below the graphs show nothing which could explain the line.

The green line is present for all four (day, week, month, year) graphs of each plugin.

Thank you for your bug report, however, it is invalid:

This green line is the "OK line" - any values above it will trigger a warning, i.e. if some disk is > 92% full, munin will consider this to be not OK any more.

I do not know if this can be turned off, you would have to look in the documentation or request this to be configurable.
If you find out anything in this regard, please consider leaving a note here.
