/**
|
||||
* <p>This class handles delivery and logging of error and alert messages
|
||||
* to the people who should be monitoring the system. It is used by the
|
||||
* Control server (to which all these messages are delivered) and
|
||||
* implements a simple rule based mechanism for managing final
|
||||
* delivery of the messages.
|
||||
* </p>
|
||||
* <p>The configured rules are compared against each message and any
|
||||
* actions associated with a matching rule are performed.<br />
|
||||
* The matching fields in each rule are -
|
||||
* </p>
|
||||
* <deflist>
|
||||
* <term>Host</term>
|
||||
* <desc>An extended regular expression to match the name of the host
|
||||
* machine on which the message originated (possibly just the host name).
|
||||
* If this is not specified, messages from any host may match.
|
||||
* </desc>
|
||||
* <term>Server</term>
|
||||
* <desc>An extended regular expression to match the name of the server
|
||||
* process from which the message originated (possibly just the server
|
||||
* name).
|
||||
* If this is not specified, messages from any server may match.
|
||||
* </desc>
|
||||
* <term>Type</term>
|
||||
* <desc>The type of message ... <em>Error</em> or <em>Alert</em>.
|
||||
* If this is not specified, messages of any type may match.
|
||||
* </desc>
|
||||
* <term>Pattern</term>
|
||||
* <desc>An extended regular expression used to match the main text
|
||||
* of the message. See the posix regcomp documentation for details
|
||||
* of enhanced posix regular expressions. If this is not present,
|
||||
* any message text will match.
|
||||
* </desc>
|
||||
* <term>Stop</term>
|
||||
* <desc>A boolean (YES or NO) saying whether rule matching should
|
||||
* stop if this rule is matched. If this is NO (the default) then
|
||||
* after any action associated with this rule is performed, matching
|
||||
* continues at the next rule.<br />
|
||||
* <em>Don't use this option injudiciusly. Try to write your pattern
|
||||
* matching rules so that most messages match a single rule to map
|
||||
* them to a nice readable version, and also match a default rule to
|
||||
* log full details to the technical team.</em>
|
||||
* </desc>
|
||||
* <term>Flush</term>
|
||||
* <desc>A boolean (YES or NO) saying whether stored messages due to
|
||||
* be sent out later should be sent out immediately after processing
|
||||
* this rule. This is useful in the event that some time critical
|
||||
* message must be sent, but should not normally be used.<br />
|
||||
* As a special case, instead of the boolean value, this may take
|
||||
* the value <em>Email</em> or <em>Sms</em> indicating that a flush
|
||||
* should be performed, but only on the specified type of messages.<br />
|
||||
* <strong>beware</strong> The batching mechanism exists to prevent
|
||||
* a single problem triggering floods of messages. You should only
|
||||
* override it using <em>Flush</em> where you are <strong>sure</strong>
|
||||
* that messages triggering the flush will be infrequent.
|
||||
* </desc>
|
||||
* </deflist>
|
||||
* <p>There are two additional fields <em>Extra1</em> and <em>Extra2</em>
|
||||
* which are matched against the message. These patterns do not effect
|
||||
* whether the action of the rule is executed or not, but the text matched
|
||||
* is made available for substitution into replacement messages.
|
||||
* </p>
|
||||
* <p>When a match is found the full message is normally sent to all the
|
||||
* destinations listed in the <em>Email</em> and <em>Sms</em> arrays in
|
||||
* the rule, and logged to all the destinations in the <em>Log</em> array.<br />
|
||||
* However, the <em>Replacement</em> field may be used to specify
|
||||
* a message to be sent in the place of the one received. Within the
|
||||
* <em>Replacement</em> string values enclosed in curly brackets will
|
||||
* be substituted as follows -
|
||||
* </p>
|
||||
* <deflist>
|
||||
* <term>Extra1</term>
|
||||
* <desc>The text in the message matched by the Extra1 pattern (if any)</desc>
|
||||
* <term>Extra2</term>
|

* <desc>The text of the original message</desc>
|
||||
* <term>Match</term>
|
||||
* <desc>The text matched by the <em>Pattern</em> if any</desc>
|
||||
* </deflist>
|
||||
* <p>The <em>Log</em> array specifies a list of log destinations which are
|
||||
* normally treated as filenames (stored in the standard log directory).
|
||||
* However, a value beginning 'database:' * is logged to a
|
||||
* database (the default database configured for SQLClient).<br />
|
||||
* After the colon you may place a table name, but if you don't then
|
||||
* the message will be logged to the 'Alert' table.<br />
|
||||
* The values logged in separate fields are the Timestamp, Type, Server, Host,
|
||||
* Extra1, Extra2, and full log text (as produced by the Replacement config)
|
||||
* is written into the Message field of the table after having been truncated
|
||||
* to 200 chars. Because of the truncation limit, it is recommended that
|
||||
* if you are trying to include the original alert {Message} (rather
|
||||
* than rewriting it) the Replacement does not include Timestamp,
|
||||
* Type, Server, Host, Extra1, Extra2 which are already saved in
|
||||
* separate fields, and would take up a lot of the 200 chars, which would
|
||||
* be better used to log the actual message.
|
||||
*
|
||||
* </p>
|
||||
* <p>The <em>Sms</em> array lists phone numbers to which Sms alerts are
|
||||
* to be sent.
|

* </p>
|
||||
* <p>The <em>Email</em> array lists email addresses to which email alerts are
|

* to be sent.<br />
|
||||
* An optional 'Subject' field may be present in the rule ... this is used
|

* to specify that the is to be tagged with the given subject line. This
|
||||
* <em>defeats</em> batching of messages in that only messages with the
