Nagios Support Forum

is it possible to get a simple list of hosts and the system uptime of that host?

From the XI gui, this can be viewed in the "Host Detail" page under the "Details" section of the left-hand menu. You could also look under the "Reports" section from the top menu followed by "Availability" from the left-hand menu for some pretty graphs!

If you were wanting to get the uptime for each host programatically, this json query is helpful (where xxx.xxx.xxx.xxx is your Nagios XI installation):
http://xxx.xxx.xxx.xxx/nagios/cgi-bin/s ... tails=true

With this JSON object, the uptime (in miliseconds) can be calculated with (last_time_up - last_time_down) for a given host.

reports/availability doesnt have anything about 'uptime'

The second option does dump out a lot of information might need to see how much effort it will take to make it useable.

thank you for your ideas

I figured how to do it.

From the XI home page, I clicked on 'Service detail' then in the search box, i entered "Uptime"

Then I used the mouse to select the entire table, and pasted it into Excel.

worked great for what I was wanting.

Glad you were able to find a solution! Is it alright if I lock this thread and mark the issue as resolved?

yes....by all means, lock away
