Measuring Latency and TraceRoute Details with Oracle Edge Services
Goal: We will try to check the latency from various OCI Data centers to Customer locations where the servers are getting accessed , for example let us assume that all customers are based out in Bangalore, we might want to know which is best available datacenter to have minimum latency for the instance to be hosted
Access Edge Services from OCI Console
Select the Source & Destination Region for Latency measurement
Access Internet Intelligence and Click on Explore Performance
Markets will be the region from where most customers are like to access the server , this is our source
Cloud Region or Vantage Point : is a place from where the actual Servers are running in Availability Domain such as Ashburn AD1, AD2 , Farnkfurt, London , Phoenix, etc
the connecting lines indicate latency in ms ( Milli Seconds )
Anything less than 50ms is great and green, About 250 ms means very high latency
You can also check for over a time period of 1 day, 7 days or 1 min or 3 mins
Check for TraceRoute
Traceroute is a utility that records the route (the specific gateway computers at each hop) through the Internet between your computer and a specified destination computer. It also calculates and displays the amount of time each hop took. Traceroute is a handy tool both for understanding where problems are in the Internet network and for getting a detailed sense of the Internet itself.
You can select Public IP address of Server and select Run troubleshooting test
Troubleshoot Latency Issues with Network Map
The interesting about accessing a server which most of us never know is each request and response goes through multiple internet service provider , from the customer location to the server and back to you , so if one of the internet service provider is slow , this reflects on the latency , so the you can check the entire path and service providers
