DNS Monitoring Software

DNS Monitoring

The primary purpose of DNS (Domain Name System) servers is to convert simple domain names into IP addresses that can be processed by computers. If the DNS server that supports your business is down, multiple services such as websites, mail servers or proxy servers may be inaccessible to the outside world. Not only that, quick response times of your DNS server to process the millions of requests handled on a daily basis are essential in order to deliver a good user experience. This makes DNS performance monitoring an integral part of any network and application ecosystem.

Applications Manager offers comprehensive DNS monitoring with real-time alerts to make sure your DNS server performance is always maximum and no issues that can impact the performance of your business applications go unnoticed. It helps you make sure your critical services are up and running at all times, ensure constant connectivity to your websites and servers, and quickly identify DNS issues.

Some critical parameters that can help monitor the DNS performance include:

Response time: The primary parameter to keep an eye on when you monitor DNS server is the response time of your DNS server.This can help identify problems from a glimpse leading to further drill down into the cause. DNS Monitoring - ManageEngine Applications Manager

DNS Server Availability: Monitoring the health and maintaining it at an optimal level will help your DNS server process incoming requests faster and be available at all times to process new requests.

Record Type: DNS servers create and rely on things called 'Records' for important information about the hostname or the domain. These records are classified into many types based on their functions. Some examples include Address Mapping record (A record), IP Version 6 Address record (AAAA record), Canonical Name record (CNAME record), etc. The record type parameter can help you understand which record type has a delayed response time and troubleshoot accordingly.

Search Field: The type of field the DNS server is currently looking up into. Examples include record name, address, target, admin, host, port, priority, etc. Again, easier to identify where the issue could be.

Search Value: This denotes the value of the field type chosen for the request above. These parameters can be associated with thresholds to get notified if there is any anomaly.

Search Time: This denotes the time taken for a search to be executed in the DNS server. Monitoring this parameter can help pinpoint the searches that take more execution time and tune the performance accordingly.

Improve DNS server troubleshooting

DNS monitoring tools are designed to track DNS requests and servers, so that performance issues are identified and resolved on time. Applications Manager helps you proactively identify common causes for DNS server failure including improper configuration, network issues, dynamic updates, inaccessibility of root servers, etc. It instantly alerts you in case of any deviations from ideal performance and helps you resolve service disruptions and avoid latency.

Resolve your domain name from multiple geographical locations

Applications Manager enables DNS monitoring from various geographies to measure end user experience across the globe. You can understand the response time of your distributed DNS servers from global monitoring locations, troubleshoot domain name resolution, and ensure minimum look up times for all users.
