Description

The SLA widget displays the availability (%) of the chosen element (cluster, host or check) for the last 7 days.
The duration time for compute last 7 days percent is between now and 00h00 last 7 days. 

2 SLA values are present:

  • Last 7 days

Between 99% to 100% :

  • Status = OK.
  • Icon = Sun

Between 97% and 99% (not included => 98,9%) :

  • Status = Warning.
  • Icon = Orange clouds hiding the sun.

Between 0% and 97% (not included => 97,9%) :

  • Status = Critical.
  • A red cloud with lightning will be displayed.

 

  • The previous day trend: 
    • It displays the SLA trend during the last day.

The previous day trend is the comparison between current day element availability and last day availability.

Example : 

  • The element with availability at 80% the last day and 90% today : The arrow is green points upwards with the text +10%
  • The element with availability at 90% the last day and 80% today : The arrow is red points downwards with the text -10%
  • The element with availability at 100% the last day and 100% today : The arrow is gray horizontal with the text 0%

Usage

As the SLA refers to the availability of an element, a click on the widget will open the Detail panel of this element in the historic tab (see the Host Detail View and History Tab chapter for more details).

Compute

 

Exemple of compute for the last 7 days percents at 10h00: 

current day100%* 10= 1000
current day - 180%* 24= 1920
current day - 290%* 24= 2160
current day - 390%* 24= 2160
current day - 485%* 24= 2040
current day - 590%* 24= 2160
current day - 6100%* 24= 2400
  ∑ 154∑ 13840

154 : hours in the last 7 days
138,40 : uptime hours in the last 7 days

13840/154 = 89%
