Hello Has anybody found problems with the results from avail.cgi when you have scheduled downtime for services? The totals for OK/WARNING/CRITICAL are fine, but under the following circumstances there are errors in the scheduled/unscheduled calculations: - The report must be run with a time period such as 'workhours'. The issue does not occur with 24x7. - The service must have a scheduled downtime period which lies outside of the report time period. Having looked through the code, I found that this was due to the critical time being calculated based on the rpttimeperiod (e.g. workhours), but the calcluation of the scheduled critical time ignoring this and always being 24x7, i.e. total(during rpttimeperiod) - scheduled(at any time) = unscheduled I made a change which got this working, but I've now found that when there is a downtime window that overlaps the time period being reported on the same issue occurs. How are others dealing with these issues, or are you not generally using scheduled downtime periods? Are there any alternative tools that can be used to extract this reporting data from Nagios? I'm willing to spend some time trying to fix avail.cgi, but I need to extract these figures as soon as possible in the meantime. Thanks Jon
