Returns a count of the number of asset tag advisory indications on a set of asset tags.

An advisory indication exists when the conditional logic of the rule evaluates to true for the asset tag. Using the AssetIndications() function will assign each of the asset rules to each of the asset tags. When the conditional logic is met the advisory indication chart marker will be displayed in Sentinel.

assetTagRules: A list of asset blueprint tag rules (mnemonics). Asset blueprint tag rules are specified on the Rules tab (in blue)

assetTags: A list of asset blueprint tags aliases. Asset blueprint tags are specified on the Tags sub tab of the Asset Blueprints tab

Returns a count of the number of model tag advisory indications on a set of model tags.

An advisory indication exists when the conditional logic of the rule evaluates to true for the model tag. Using the ModelIndications() function will assign each of the model rules to each of the model tags. When the conditional logic is met the advisory indication chart marker will be displayed in Sentinel.

model: A name of a model in the asset blueprint. Only one model may be specified. All modelTagRules will counted from this model only
