Stackdriver to test my site up alert slow
We are using cloudflare as our site CDN provider. We use stackdriver to test the site availability from outside, and we have the time checking interval set for 1 minute. We use Scalyr as our log collector and analyse the logs, then ssend alert to us if it find certain pre-define errors in the logs. what we have experiences are when the site is down(user can not access it), Scalyr always alert us first, after 3-5 minutes, we got stackdriver's alert.
As Scalyr traces the log details, sometimes the alert may not be for site down, therefore we need to reply on Stackdriver for this. I tried to remove the location check in limit it just within the US, that did not help at all and we pretty much get the alert after the site is down for about 5-6 min.
Anything else I can do to improve stackdriver alerting latency?
