New Columns in SLA Report
The SLA report does not have an option to include information about SDT if the event is in the past. Since reports are often developed to look at sla information post-event it's imperative that report columns be added that reflect historical SDT info as well. I recommend not just including the sdted field to indicate whether or not the alert began in a SDT window, but to instead add a new field/column for % in SDT or SDT Duration that provides an indicator as to how much of that alert's period was happening in a SDT window. Example: Planned maintenance window is 2-4. IT change initiated at 2:30 and services are brought down. Alert generates and flags true for insdt and sdted (i think). If the change goes bad and services are still down at 4 AM the insdt flag is set to false (i think). The change implementer restores service at 4:30 and the alert clears. To report on downtime for that alert correctly we would need to know what portion of that downtime occurred within or outside of SDT. If we assumed that since the alert was generated in an SDT window (sdted=true) the entire duration was planned then we are incorrect an SLA report on downtime for that instance check would be false.0Views0likes1CommentSLA report based on device uptime during "Last calendar Month"?
Hello! My challenge is how to calculate proper SLA time (in minutes) during the last calendar month. Currently the Threshold must be set manually. The problem is that manymonths have different amount of minutes so single value might notgive 100% correct result. Having dynamic thresholds would be much better option. Thank you!6Views0likes1CommentHow is SLA report calculated (specifically internal service check related)
Could somebody explain how is SLA calculated for internal service checks? I read this but it didn't seems to apply to the report I created. /topic/1015-a-closer-look-at-how-sla-is-calculated-in-reports/ I have an internal service check scheduled to do stat test every minute. There were 4 network errors (status = 8) within the last 24 hours. I created a report using SLA widget to report 24 hours SLA and it showed100% during the past 24 hours. If it's calculated to the seconds, thecalculation would be: (24(hr) x 60(min) x 60 (sec) -4 (errors))/(24(hr) x 60(min) x 60 (sec)) x 100% = 100.00%, which seems to match. So, to confirm, I changed the report config to narrow down to 2 hours (in which 2 of the errors appeared), which should show SLA of 99.97% (i.e. (2x60x60-42)/(2x60x60)) but SLA report shows 100% still.
