Oracle::Table ExtentsThe Oracle::Table Extents probe monitors an Oracle database instance and collects the followingmetrics:• Allocated Extents-Any Table — The total number of extents for any table.• Available Extents-Any Table — The percentage of available extents for any table.In Oracle, table extents are how a table grows. When a table is full, it is extended by an amount ofspace configured when the table is created. Extents are configured on a per-table basis, with an extentsize and a maximum number of extents.For example, a table that starts with 10 MB of space and is configured with an extent size of 1 MBand max extents of 10 can grow to a maximum of 20 MB (by being extended by 1 MB ten times).This probe can be configured to alert by (1) the number of allocated extents (e.g. "go critical when thetable has been extended 5 or more times"), or (2) the table is extended past a certain percentage of itsmax extents (e.g. "go critical when the table has exhausted 80% or more of its max extents").The required Table Owner and Table Name fields contain a default value of % that will match anytable owner or name.Field ValueOracle SID*Oracle Username*Oracle Password*Oracle Port* 1521Table Owner* %Table Name* %Timeout* 30Critical Maximum Allocated ExtentsWarning Maximum Allocated ExtentsCritical Maximum Available ExtentsWarning Maximum Available ExtentsTable C-60.
