33 An FS::log object represents a log entry. FS::log inherits from
34 FS::Record. The following fields are currently supported:
38 =item lognum - primary key
40 =item _date - Unix timestamp
42 =item agentnum - L<FS::agent> to which the log pertains. If it involves a
43 specific customer, package, service, invoice, or other agent-specific object,
44 this will be set to that agentnum.
46 =item tablename - table name to which the log pertains, if any.
48 =item tablenum - foreign key to that table.
50 =item level - log level: 'debug', 'info', 'notice', 'warning', 'error',
51 'critical', 'alert', 'emergency'.
53 =item message - contents of the log entry
63 Creates a new log entry. Use FS::Log instead of calling this directly,
70 =item insert [ CONTEXT... ]
72 Adds this record to the database. If there is an error, returns the error,
73 otherwise returns false.
75 CONTEXT may be a list of context tags to attach to this record.
77 Will send emails according to the conditions in L<FS::log_email>.

195 Returns a qsearch hash expression to search for parameters specified in
196 HASHREF. Valid parameters are:
202 =item date - arrayref of start and end date
204 =item level - either a specific level, or an arrayref of min and max level
206 =item context - a context string that the log entry must have. This may
207 change in the future to allow searching for combinations of context strings.
209 =item object - any database object, to find log entries related to it.
211 =item tablename, tablenum - alternate way of specifying 'object'.
213 =item custnum - a customer number, to find log entries related to the customer
214 or any of their subordinate objects (invoices, packages, etc.).
216 =item message - a text string to search in messages. The search will be
217 a case-insensitive LIKE with % appended at both ends.
