Enh : Add Previous State and Previous State Duration in logs

[DessaiImrane]

Hi,

It may be interesting if we could have Previous State and Previous State Duration in logs.
It can be useful to work out Availabilty ... in a very simple manner.

Here is a try of an algorithm :

If current_log.type ="Service Alert" or "Host Alert"
and current_log.state != previous_log.state

then
Add previous state and duration in current log

I think that : before writing a new log, shinken has all needed informations to find last state and last state duration so that it should be easy to add it when writing the log than calculating it afterward.

What do you think ?

I think we should not use log for what they are not done for, and such use case it one of them. Reporting should be with a real module that will compute it in a good way, and not just the simple availability ON/OFF. So even if it solve the availability problem, I do not solve the reporting one, and this one is the real "root problem" I think :)
