1.4 Manually Clearing Trend Graph History
For older versions of web server firmware that do not have the “Clear Log Data” button, follow the
procedure below.
Trend graph history can be cleared by first powering down the gumstix device, then moving the
microSD card into a microSD card reader on a Linux machine (or any other machine which can read
ext2 file systems) and removing every file
except Cleanup.rb in the directory /espec/log/.
The following commands can be run to do this:
Mount [microSD device] [mount point]
cd [mount point]
rm espec/log/chamber_*
Unmount the micro SD card and return it to the gumstix device.
Note: Many modern Linux distributions will mount the microSD card for you and put a link
to it on your desktop.
