Hi,

Thanks for the report.

Could you please also share the hard state change that happened before your mentioned change?

A screenshot of the history would help.

All the best, Eric

In the past few months I have observed strange behaviour. The reports covering the last month change during the current month. Which should not happen, since the last month is already finished and therefore there are no more changes. The reports tend to become more realistic towards the end of the month, at least there are less services with more than 100%.

Here is an example same report of last month:

(please note the different creation dates of the Report)

I have exported the state history of the services above: idoreports-issues-24.txt Filter uses for this export: state_type LIKE '1' AND object_id IN ('16528','16536','16538','16535','16541','16542') and state_time > '2020-03-01 00:00:00' and state_time < '2020-03-31 23:59:59'

As far as I can see all services that are changing their percentage value over the time have an wildcard (*) at the end of their service name, so that is probably a different issue.

I've encountered this issue as well. It happened when I had a host in downtime. During downtime, the SLA did not take the downtime into effect. After I removed the downtime, the SLA then showed above 100%. Here is the state change history: The report is covering a 1 week time span.

that happens in strange downtime scenarios if you devide by total time this can't happen https://github.com/moreamazingnick/icingaweb2-module-idoreports
