Set resource limits for Clark Kent

Several parameters are now available for the reporter daemon process ( to control resource usage. These can be used to reduce the chances that a malformed report can cause indigestion on a database or reports server. The new parameters, which can be set in opensrf.xml or as command-line switches for are

Number of minutes to allow a report’s underlying SQL query to run before it gets cancelled. Default value is 60 minutes. If a report’s query gets cancelled, the error_text value will be set to a valid that indicates that the allowed time was exceeded.

Number of rows permitted in the query’s output before Clark Kent refuses to attempt to draw a graph. Default value is 1,000 rows.

If set, truncates the report’s output to the specified number of hits. Note that it will not be apparent to a staff user if the report’s output has been truncated. Default value is unlimited.

The report concurrency (i.e., the number of reports that Clark Kent will run in parallel) can now also be controlled via the opensrf.xml setting //reporter/setup/parallel.
