Network Uptime

[snootalope]

Sorry, if this topic isn't in the right place, figured it reach more network admins here.

So, for over the past year I've kept logs of exactly the times when something (server, remote office, switch, etc.) has went down and when it came back up.

I'm trying to determine how exactly I would find our network uptime. Is it best to break it down into categories, like network or server/service? Or does one just take all the downtime combined and figure that into ever day, hour, minute, and second of the past year? That just wouldn't seem to be accurate to me beings there are remote office and others can continue to work while one is down..

Please, lend me some advice if you have some..

Thanks!

Well, what I did was add up the actual work days, then find the full amount of open office hours, and take aways the amount of downtime hours from that.. that'll do.

99.4% uptime! woo-hoo!

There are too many factors involved here. Some users base downtime on the availability of critical applications/systems others in terms of services.
Let's take mail for example. Downtime can be caused by network problems, application issues and/or server issues. You can take all these factors into consideration when measuring downtime for mail.
If you need to provide uptime statistics to management, then they should help you define what exactly what applications/systems are they looking for.
Hope this helps.
