variables

Variables extracted via DPI from the monitored system.

var_key	The primary key of this data source
host	The node to which this variable belongs to
host_label	The label of the node to which this variable belongs to
namespace	It is the identifier of the subsystem in the producer to which the variable belongs. Also known as the remote terminal unit (RTU) identifier (ID) of the variable.
name	The name of the variable, likely an identifier of the memory area
label	The human-readable name of the variable
unit	The unit for the value of the variable
scale	The scale of the variable. By default it is 1.0, and can be configured/changed with external information.
offset	The offset of the variable. By default it is 0.0, and can be configured/changed with external information.
type	The type of the value of the variable.
is_numeric	True if it represents a number
min_value	The minimum observed value
max_value	The maximum observed value
value	The live, last observed value of the variable. Upon restart, this value is unknown because it needs to reflect the real time status.
bit_value	The live, last observed value of the variable, expressed in bits. Upon restart, this value is unknown because it needs to reflect the real time status.
last_value	This is the last observed value, and is persisted on reboots
last_value_is_valid	True if the last value is valid (has valid quality)
last_value_quality	The quality of the last value
last_cause	The cause of the last value
protocol	The protocol in which this entity has been observed
last_function_code_info	The last value function code information
last_function_code	The last value function code
first_activity_time	Timestamp in epoch milliseconds when this variable was found for the first time
last_range_change_time	Timestamp in epoch milliseconds when this variable's range changed
last_activity_time	Timestamp in epoch milliseconds when this variable was detected for the last time
last_update_time	Timestamp in epoch milliseconds of the last valid quality
last_valid_quality_time	Timestamp in epoch milliseconds of the last time quality was valid
request_count	The number of times this variable has been accessed
changes_count	The number of times this variable has changed
latest_bit_change	Indices of the flipped bits during the latest variable change
last_client	The last node that accessed this variable (in read or write mode)
history_status	Tells if the history is eanbled or not on this variable
active_checks	List of active real-time checks on the entity
flow_status	Tells the status of the flow, that is if the variable has a cyclic behavior or not
flow_anomalies	Reports anomalies in the flow, if any
flow_anomaly_in_progress	Reports a flow anomaly is in progress or not
flow_hiccups_percent	Shows the amount if hiccups in the flow
flow_stats.avg	Shows the average access time
flow_stats.var	Shows the variance of the access time
