MineMeld aggregator nodes support whitelists. If an indicator is in a whitelist, the aggregator nodes won't send matching indicators to downstream nodes. Whitelists can also be shared by multiple aggregators.
Aggregator nodes created using stdlib prototypes (stdlib.aggregatorDomain, stdlib.aggregatorURL, stdlib.aggregatorIPv4Generic, stdlib.aggregatorIPv4Outbound, stdlib.aggregatorIPv4Inbound) will whitelists indicators generated by Miner nodes whose name starts with prefix wl (lowercase).
In the following example a whitelist Miner will be created for an IPv4 aggregator node.
In CONFIG, click + to add a new node. Specify a name starting with "wl" and select stdlib.listIPv4Generic as prototype. Enable Output and then press OK.
In CONFIG, click on the INPUTS field of the selected aggregator. In the dialog add the new whitelist node to the list of INPUTS.
Just press COMMIT in the CONFIG page.
In NODES, click on the new whitelist node and select INDICATORS in the menu on the left.
Click + to add new indicators. Pressing OK will automatically save the indicator and the list. It could take up to 1 minute for the new indicator to be pushed downstream to the aggregator node.
