Great question. There are two answers:
1) There is an if/then/else operator that you can use in the ${eval: xxx}
macro.
To convert the number to the corresponding string in your <snmp-device-display>
section, write:
${eval: $val == 1 ? "OK" : "Bad"}
This says, if $val is one, output "OK", otherwise output "Bad". These can be
chained to test for multiple cases:
${eval: $val == 1 ? "OK" : $val == 2 ? "Bad" : $val == 3 ? "Other" : $val }
This outputs the following:
OK if it's 1
Bad if it's 2
Other if it's 3
$val if it's anything else
2) If the values come from an enumeration in a MIB, and you have imported
that
MIB into InterMapper, then a new facility will use information from the MIB to
display the desired string. [This was added in a recent version of InterMapper
4.5. We're adding this documentation to the Developer Guide as we speak...]
For example, the variable tcpRtoAlgorithm comes from the TCP-MIB that is
preloaded in InterMapper. If you read the MIB, you'll see that tcpRtoAlgorithm
is defined like this:
tcpRtoAlgorithm OBJECT-TYPE
SYNTAX INTEGER {
other(1), -- none of the following
constant(2), -- a constant rto
rsre(3), -- MIL-STD-1778, Appendix B
vanj(4) -- Van Jacobson's algorithm [5]
} ... etc...
To make InterMapper display the string instead of the number, create a variable
with a type of STRING (instead of DEFAULT or INTEGER), like this:
<snmp-device-variables>
tcpRtoAlgorithm, tcpRtoAlgorithm.0, STRING, "RTO Algorithm"
</snmp-device-variables>
When you use $tcpRtoAlgorithm in the <snmp-device-display> section, it will
appear as one of the strings above, instead of a number.
Please get back to me if you have further questions. Thanks.
