What interval do you use for monitoring?
I'm using NodeQuery and Uptime Robot to keep an eye on the health and uptime of 4 VPS's and one hosted Web site.
If you use these kinds of services, what interval do you use to check the health and uptime? For commercial sites, and client sites, I can see that you would certainly want to ensure that your site is up 100%, so the check interval would be quite low (like every few minutes). in my case, my sites are hobby and test instances, so downtime isn't as critical, so I have the check interval set rather large at 30 minutes.
Do you recommend short intervals for all types of sites?
On one hand, uptime is uptime, regardless of the specific use, so a short interval seems in order. And if the host is reliable (something often failing on many Low-End hosts) then I should never see alerts, and expect very close to 100% uptime.
On the other hand, for better or for worse, I have bought into the "you get what you pay for" expectation of Low-End hosted sites. Since I am admittedly using some VERY Low-End hosts, when a site has an uptime of, say, 97%, I don't see that as a really big deal.
