informations can only be read in ’Oﬄine’ state. For Option Fusion UMTS Quad the

4.21.2. Sample Conﬁguration For RRDTOOL

Depending on hardware it is possible to display signal strength and bit errors in OPT_HTTPD

(Page 123). With OPT_RRDTOOL you can even record these values. With some hardware

this does not make sense because status informations can only be read in in ’Oﬄine’ state.

Set ’umts’ as data source for RRD.

Sample conﬁguration for rrdtool:

RRDTOOL_x_SOURCE='umts'

RRDTOOL_x_LABEL='UMTS status'

RRDTOOL_x_OPTIONS_N='2'

RRDTOOL_x_OPTIONS_1='signal'

RRDTOOL_x_OPTIONS_1_LABEL='signal strength'

RRDTOOL_x_OPTIONS_2='error'

RRDTOOL_x_OPTIONS_2_LABEL='Bit errors'
