TESTING ORIGIN TOHIGHWINDS EDGE PERFORMANCE
WITH BAROMETER
If you’ve logged in to StrikeTracker today you may have noticed a
new option under the tools section of the left navigation bar.This is
an exciting new bit of functionality that we’re calling Barometer.
Barometer is a tool that surfaces functionality we’ve been developing on
the back end of our stack to determine network performance from a given
Highwinds point of presence (PoP) to a publicly available http origin.
Barometer allows you to test network connectivity between the CDN and your
origin and using it is very simple. Enter a URL for us to test and we’ll request that
URL from each data center on our network and report statistics such as ping time,
response time, and status code.
The completion bar will animate while we perform a number of tests and collect data from across our network.
Once those operations are finished you’ll get a map and a response screen stack-ranked to display the most
performant PoPs for that particular origin vs. those which took longer total time to answer.
Looking at each individual PoP you’ll see:
Data Center location
Response time breakdown
Total response time
HTTP status code in the response
The response time breakdown is further comprised of:
Time to
DNS resolution
Connection
SSL negotiation complete
First byte
Content download
You can view the values for these segments in the
tooltip of the stacked bar by hovering over it.
You can also drill in to a particular PoP connection, using the downward expansion arrow
next to it.
This will then reveal all of the detailed metrics for that PoP.
You can always reach our network support team at any time by visiting our customer support portal.
