6.3. Reading the generated reports

The content of every SysOrb report is structured the same way as your domain heirarchy. I.e. each domain is represented by a section in the report, with subdomains represented by subsections. When browsing through the report you may expand or collapse each section, or you can choose the printable format in which every section are expanded.

When calculating the availablity percentages for a given check, SysOrb does the following: For each point in time within the interval for which this report is to be generated, the check fall into exactly one of the following three cases:

Confimed downtime

SysOrb has statistical data indicating that SysOrb performed the check, but failed to get a reply. Or that the reply was outside the configured alarm thresholds. In short, this is the periods in which a red icon has appeared for this check.

Confirmed uptime

SysOrb has statistical data indicating the the check was performed, and returned a reply which was inside the alarm thresholds (but may have been outside the warning thresholds.) In short, this is the periods in which a green or yellow icon has appeared for this check.

Unconfirmed uptime

SysOrb has no statistical data for the period. This may be caused by the SysOrb server or agent having been down for a period, or that the check was simply not configured at that time.

The availability percentage for a single check, visible at the very top of the section describing a check, is simply the sum of "Confimed uptime" and "Unconfirmed uptime". In adding these numbers SysOrb makes the optimistic assumtion, that even though the SysOrb server is down for a period of time, everything else keeps running.

The total availability of a node is calculated as the average of the availabilities of every one of its checks, which are included in the report. The total availability of a domain is likewise calculted as the average of the availabilities of every node in the domain (including subdomains), which are included in the report.
