Supports monitoring in network quality scenarios through multiple methods such as Ping (ICMP/TCP/UDP), DNS, and Tracert. Targets application network stability, route stability, DNS resolution accuracy rate, including ICMP latency and packet loss rate.
1. Click Multi-dimensional Analysis in the left menu bar > Select Network Quality Dial Test Task.
2. On the multidimensional analysis page, you can analyze dial test data in multiple dimensions using maps, line charts, digital graphs, and detailed data.

Description
Overall latency (ms)
The time required for a message or packet to travel from one end of a network to the other. Transmission delay is determined by Internet routing conditions. If transmitted over a low-speed channel or when the channel is too crowded, it may result in long-term delay or packet loss.
Packet loss rate (%)
The ratio of lost packets to the total number of transmitted packets. Packet loss is generally caused by several factors: physical line failure, device failure, network congestion, routing errors, etc.
DNS query time (ms)
Time required for input domain name to convert to IP address.
Resolution Error Rate (%)
Ratio of domain name resolution errors, calculated as (number of resolution errors / total number of domain name resolutions) × 100%.
Number of valid dial tests (times)
Number of valid data samples.
Number of error test attempts (times)
Number of error data samples.
TTL(s)
TTL (Time-To-Live) is the retention time of a domain name resolution record in a DNS server. When DNS servers around the world receive parse requests, they send parse requests to the NS server designated by the domain name to obtain resolution records. After obtaining this record, it will be saved in the DNS server for a period of time. During this period, if another parse request for the same domain name is received, the DNS server will no longer send a request to the NS server but directly return the previously obtained record. The time this record is retained on the DNS server is the TTL value.
Availability (%)
Availability is the success rate of clients executing dial test tasks accessing the target. Availability = Number of valid dial tests / Total number of test tasks × 100%.
Traceroute latency (ms)
Average latency of all hops during the entire Tracert process.
Tracer number of hops
The count of network device points transited.
