Source Data Alerts

This article provides information about the types of data source alerts available in Nexla and instructions for setting up these alerts.

1. Types of Source Data Alerts​

In Nexla, source data alerts can be set up to produce notifications of changes in data ingestion from any data source.

1.1 Source Data Volume Alerts​

Source data volume alerts can be configured to notify users when the volume of data ingested from a data source changes by a specified percentage compared to the data volume ingested at a specified previous time. The alert be applied to data volume increases, decreases, or non-directionally specific changes according to selected settings. Nexla can perform daily, hourly, or continuous checks for changes in data volume.

1.2 Source Data Delay Alerts​

Source data delay alerts can be configured such that users receive notifications about data ingestion delays for any data source. These alerts can be configured to notify users of increases, decreases, or non-directionally specific changes in the delay of data ingestion from a data source. Nexla can also perform daily, hourly, or continuous checks for changes in the data volume delay.
