I am not sure if there is a more efficient way to do this, but I dealt with Hex-
String values in a test I haven't yet made available (as it will probably
cause the all-clear-tests issue on version of devmon without another local
change I am testing on many routers). In the example here, I am converting the
cipsStaticCryptomapPeerB OID, which looks like this:
CISCO-SMI::ciscoExperiment.62.1.2.3.3.1.4.5.99.105.115.99.111.10 = Hex-STRING:
41 3D 88 04
to a printable string in the cipsStaticCryptomapPeer OID:
$ cat /usr/share/devmon/templates/cisco-2811/vpn/oids
cipsStaticCryptomapType : 1.3.6.1.4.1.9.10.62.1.2.3.3.1.2 : branch
cipsStaticCryptomapDescr : 1.3.6.1.4.1.9.10.62.1.2.3.3.1.3 : branch
cipsStaticCryptomapPeerB : 1.3.6.1.4.1.9.10.62.1.2.3.3.1.4 : branch
cipsStaticCryptomapNumPeers : 1.3.6.1.4.1.9.10.62.1.2.3.3.1.5 : branch
$ cat /usr/share/devmon/templates/cisco-2811/vpn/transforms
cipsStaticCryptomapPeerp1B : SUBSTR :{cipsStaticCryptomapPeerB} 0 1
cipsStaticCryptomapPeerp2B : SUBSTR :{cipsStaticCryptomapPeerB} 1 1
cipsStaticCryptomapPeerp3B : SUBSTR :{cipsStaticCryptomapPeerB} 2 1
cipsStaticCryptomapPeerp4B : SUBSTR :{cipsStaticCryptomapPeerB} 3 1
cipsStaticCryptomapPeerp1H : UNPACK : {cipsStaticCryptomapPeerp1B} H2
cipsStaticCryptomapPeerp2H : UNPACK : {cipsStaticCryptomapPeerp2B} H2
cipsStaticCryptomapPeerp3H : UNPACK : {cipsStaticCryptomapPeerp3B} H2
cipsStaticCryptomapPeerp4H : UNPACK : {cipsStaticCryptomapPeerp4B} H2
cipsStaticCryptomapPeerp1 : CONVERT : {cipsStaticCryptomapPeerp1H} hex
cipsStaticCryptomapPeerp2 : CONVERT : {cipsStaticCryptomapPeerp2H} hex
cipsStaticCryptomapPeerp3 : CONVERT : {cipsStaticCryptomapPeerp3H} hex
cipsStaticCryptomapPeerp4 : CONVERT : {cipsStaticCryptomapPeerp4H} hex
cipsStaticCryptomapPeer : REGSUB : {cipsStaticCryptomapPeerB}
/.*/{cipsStaticCryptomapPeerp1}.{cipsStaticCryptomapPeerp2}.
{cipsStaticCryptomapPeerp3}.{cipsStaticCryptomapPeerp4}/
If you need all 8 hex pairs, you could need 8 SUBSTR, 8 UNPACK, and 8 CONVERT
transforms. If you only need the last value, you could get away with just one
of each.
I plan on adding some better operators to automatically convert from common
SNMP types (or, possibly some automatic conversion of types).
