http://askubuntu.com – I'm curious as to how I could have negative downtime that keeps increasing, as well as uptime beyond 100%. I'm getting the below output from uprecords -adM: # Uptime | System Boot up ----------------------------+--------------------------------------------------- -> 1 14 days, 21:12:15 | Linux 3.2.0-29-generic Tue Aug 21 21:02:27 2012 2 14 days, 15:31:05 | Linux 3.2.0-29-generic Tue Aug 21 21:03:33 2012 ----------------------------+--------------------------------------------------- NewRec 0 days, 05:41:09 | sinc (HowTos)

Stories similar to Negative downtime, 200% uptime reported by uprecords/uptimed

Hi. I'm somewhat new to Fedora, though I've dabbled with Gentoo for a number of years. I installed the package "uptimed", but every time I run uprecords I get a message:

Code: uptimed: no useable database found. So far, my searches in the internet have found no help, and the man pages for both uptimed and uprecords also provide no help.

Any ideas?

I have heard or read that one Linux server had an uptime of some 2000+ days before it was rebooted.

What is the longest uptime for your servers before a reboot was required? And what applications/servers was/is running on the servers?

I'm curious mostly because I want to learn what Linux is capable of and I wanna be amazed by Linux.

I was testing out the linux api while working on something but got stuck on the following output.

[Abhii@localhost net]$ cat /proc/uptime 39135.53 149657.73

As per specs the first number should be the Uptime and the second number should be the time system has stayed idle.

So why is the former less then latter ???

As an extra piece of info my version information

Linux version 3.5.2-3.fc17.x86

I'm researching setting up a dedicated server to run some virtual private servers on (for my friends, hosting some websites, etc.). However, I am stuck as to how to maintain uptime of the guest operating systems in the face of required downtime of the host machine.

By required downtime I am mainly thinking of security updates etc.

on running the uptime command, it tells me that I have 5 users logged in. I don't understand this since I have on one user registered on this computer. This is the output

11:07:19 up 5 days, 1:11, 5 users, load average: 0.42, 0.67, 0.56

who command 50 weeks 4 days ago

I have a question about the who command.

When I type who

The output of my terminal is

username tty1 2012-06-02 06:25 (:0) username pts/0 2012-06-02 13:41 (:0)

My question is what is pts/0 and what is ttyl? Also, what is the (:0) at the end?

I need to find PC uptime from first day until now.

Is logged this uptime hours in somewhere?

Any file log this times?

Can I do that?

I'm new to linux and I installed ubuntu 11.10 x64. I got a HP Envy 14 laptop (i7 second gen) and my batterytime is half the uptime I get in windows 7. Now I got 2hours and it discharges in 30w. In windows I get about 4-5 hours uptime.

I have done some guides so I only use the integrated graphicscard. I ran powertop and pasted it here below, if someone can get something out of it..

Hi

One of our server is showing the uptime 0hr 5mints there is no log in /var/log/messages there is no log in command "last" kernel version is 2.4.9 (RH2.1 AS)

What could be the reason for this. is this issue is related to uptime counter reached max how to verify this. Best Regards KVK
