/etc/opt/SUNWmd/mdlogd.cf is used to control the daemon's behavior.
It is an ASCII file with the basic form:
ENTERPRISE = <enterprise-id>
OBJECTID = <object-id>
<reg-exp> <trap-destination> <generic trap #> <specific trap #> [ ... ]
<enterprise-id> and <object-id> are required and must be specified. They are used by all traps generated by the daemon.
<enterprise-id> is the SNMP identifier for the enterprise to which the system running the daemon belongs. For example, the Sun Microsystems enterprise ID is: 1.3.6.1.4.1.42.
<object-id> is the SNMP identifier of the system running the daemon. For example, the object-id of a host within the Sun enterprise might be: 1.3.6.1.4.1.42.10.
The remainder of the file consists of tuples which describe a regular expression and the specific SNMP trap to be generated when a matching message is written to the system console.
Each tuple has four fields:
Traps of type 6 include an additional enterprise specific trap number.
Given this configuration file and an error written to /dev/console on host spin which looks like:
WARNING: md: d6: /dev/dsk/c3t3d0s7 needs maintenance
an SNMP trap will be dispatched.
If this trap were received by SunNetManager, it would look like:
Wed Feb 21 15:40:41 1996 [ spin ] : Trap:
sequence=2
receive-time=Wed Feb 21 15:40:41 1996 version=0

enterprise=Sun Microsystems

trap-type=enterprise specific trap: 2

1.1 Any character that is not a special character (to be defined) matches itself.
1.2 A backslash (\) followed by a special character matches the literal character itself (i.e., this `escapes' the special character).
1.3 The `special' characters are: + * ? . [ ] ^ $
1.4 The period (.) matches any character except the newline. E.g., `.umpty' matches either `Humpty' or `Dumpty'.
1.5 A set of characters enclosed in brackets ([]) is a one-character RE that matches any of the characters in that set. E.g., `[akm]' matches either an `a', `k' or `m'. A range of characters can be indicated with a dash. E.g., `[a-z]' matches any lower-case letter. However, if the first character of the set is the caret (^), the the RE matches any character except those in the set. It does not match the empty string. Example: [^akm] matches any character except `a', `k' or `m'. The caret loses its special meaning if it is not the first character of the set.
The following rules can be used to build a multicharacter RE:
2.1 A one-character RE followed by an asterisk (*) matches zero or more occurences of the RE. Hence, [a-z]* matches zero or more lower-case characters.
2.2 A one-character RE followed by a plus (+) matches one or more occurences of the RE. Hence, [a-z]+ matches one or more lower-case characters.
2.3 A question mark (?) is an optional element. The preceeding RE can occur zero or once in the string -- no more. E.g., xy?z matches either xyz or xz.
2.4 The concatenation of REs is an RE that matches the corresponding concatenation of strings. E.g., [A-Z][a-z]* matches any capitalized word.
Finally, the entire regular expression can be anchored to match only the beginning or end of a line:
3.1 If the caret (^) is at the beginning of the RE, then the matched string must be at the beginning of a line.
3.2 If the dollar sign ($) is at the end of the RE, then the matched string must be at the end of the line.
The following escape codes can be used to match control characters:
