time domain measuring cache hits, origin hits, response codes,
response time, total hits and total bytes. it all comes from
telemetry. Telemetry represents change in state over change in time.
In simple terms telemetry indicates events. Logs provide telemetry
because logs record an event - the state of a component at a point in
time. A web server access log record HTTP response message
exchange events - the final state of a dispatched HTTP request. At any layer
from browser to data source, telemetry from the logs anchor the
complexity of our architecture in the simplicity of time and
uniformity of web resources identifiers.
I am working on cGauge but took some time today to try and get more
eyes on the data.
There is something more powerful than web server access logs. Try adding an event for the initial state of a dispatched HTTP request!
