Find Uptime Average

[rlinux57]

Kindly let me know the method to find uptime average of server, i have configured nagiosgraph with NMS core. I have attached the screenshot i didn't understand to find out the average method of nagiosgraph.

So the graph is showing the average of the value which you are graphing at the start of the month uptime was at 213.78k ene od the month it was 264.86k it summs every value then divides it by the total number of values, this is how averages are devised

what you are asking for is a bit strange, the average uptime is not something I would expect someone to want as each time nagios checks to read the value of uptime it has increased, so if you are looking at uptime over a month and the server has not shut down you will see an increase of 43800 minutes over the month each time it is read.

so you would more likely want to know percentage of availability e.g. I typically report on system xyz was avaliable for 100% of the period, as we have a SLA with the business to delvier 99.95% uptime

this is easily produced with nagios by using the built in availability report which can be accessed via the menu on the left of the screen

I have attached a copy of the report from my test system

What does 213.78k 'k' represents ?

I assume it correlates with the graph you posted - what host / service check is running to monitor it?
