DNS Alerts for Client Devices

overview the nile access service continuously monitors the dns transactions across all connected client devices when a significant percentage of clients encounter dns failures, the nile access service generates alerts to notify the network administrators dns alert thresholds the nile access service uses the following thresholds to determine when to generate dns alerts 5% to 10% client failures if 1% to 10% of the clients attempting dns transactions in the last 15 minutes (with a sliding window of 5 minutes) have encountered failures, the following alert is generated dns alert 5% <= clients < 10% <# number> of clients attempting dns transactions in the last 15 minutes encountered failures at \<site> for \<x hrs/mins> 10% to 25% client failures if 10% to 25% of the clients attempting dns transactions in the last 15 minutes have encountered failures, the following alert is generated dns alert 10% <= clients < 25% <# number> of clients (>10%) attempting dns transactions in the last 15 minutes encountered failures at \<site> for \<x hrs/mins> 25% to 100% client failures if 25% to 100% of the clients attempting dns transactions in the last 15 minutes have encountered failures, the following alert is generated dns alert 25% <= clients <= 100% <# number> of clients (>25%) attempting dns transactions in the last 15 minutes encountered failures at \<site> for \<x hrs/mins> alert lifecycle the dns alert is "closed" when the condition is cleared, i e , when less than 1% of the clients are encountering dns failures alert categorization and visibility the dns alerts are categorized as "client devices" in the nile cloud services portal's alert table when a user clicks on the alert, they are taken to the "devices" page, which displays the filtered list of devices with the corresponding dns errors by providing these dns alerts, the nile access service helps network administrators quickly identify and address any issues related to dns authentication, ensuring the seamless operation of the network infrastructure
