Hello,
We are using Icinga 1.4.1 to kick off various system checks in a fairly
large configuration. All of the checks are Active Checks (No passive
checks). But we are seeing a strange problem. If the timeperiod is
"legal" during the Icinga process startup (i.e. if a service can be
scheduled starting from that time), than it will be scheduled. But, if
the first "legal" time to run the process is in the future, then Icinga
will not schedule it, either now or later.
For example, imagine that you have three timeperiods in timeperiods.cfg:
define timeperiod{
timeperiod_name 24x7
alias 24 Hours A Day, 7 Days A Week
sunday 00:00-24:00
monday 00:00-24:00
tuesday 00:00-24:00
wednesday 00:00-24:00
thursday 00:00-24:00
friday 00:00-24:00
saturday 00:00-24:00
}
define timeperiod{
timeperiod_name workhours
alias Monday-Friday days
monday 08:00-17:00
tuesday 08:00-17:00
wednesday 08:00-17:00
thursday 08:00-17:00
friday 08:00-17:00
}
define timeperiod{
timeperiod_name offhours
alias Not Monday-Saturday during work
sunday 00:00-24:00
monday 00:00-07:00,20:00-24:00
tuesday 00:00-07:00,20:00-24:00
wednesday 00:00-07:00,20:00-24:00
thursday 00:00-07:00,20:00-24:00
friday 00:00-07:00,20:00-24:00
saturday 00:00-07:00,20:00-24:00
}
Now, imagine that at 14:00 (2:00pm) on Monday, you stop Icinga, delete
retention.dat and restart Icinga. The 24x7 services can be scheduled
right away and will be run. The services with a checkperiod of
"workhours" can also be scheduled right away and will be run. But the
services scheduled for "offhours" cannot be run yet. Icinga *should*
schedule them for a time after 20:00 (either right now or after 20:00
comes). But, in fact, what it seems to do is to flag them in status.dat
as "should_be_scheduled=0" and they show up in the web interface as
"service is not scheduled to be checked..." This is not updated-after
20:00 or ever. These services just don't get scheduled and aren't ever
run.
If you restart Icinga after 20:00 with "retain schedules" turned on,
then the offhours timeperiod is "legal" and it will update the missing
offhours schedule entries. But that is kind of a workaround hack. Is
there something that could be changed in the configuration to enable
Icinga to correctly schedule everything when it starts-even the
timeperiods that are not ready to run yet? Or is this just kind of a
bug?
This seems like a fairly simple question, but I haven't seen it
addressed anywhere, either in the online docs or in the support groups.
So any insight would be very useful.
Thanks very much,
Geoff Kransdorf
