This only supports output, not input fields, but input fields generally don't have poorly formed mibs, this patch adds an oid_suffix tag to the xml. patched against 0.8.7a

Oh, I volunteer for this, including docs, for sure. But I first need to understand better.

Just my 2 cents to this feature request thread...

I'm trying to graph Quality of Service (QoS) statistics on a Cisco Device. The SNMP walk for the particular OID i'm graphing (QOSDropPackets in this case) shows the following

SNMPv2-SMI::enterprises.9.9.189.1.3.2.1.7.10101.1.1 = Counter64: 0
SNMPv2-SMI::enterprises.9.9.189.1.3.2.1.7.10101.2.1 = Counter64: 0
SNMPv2-SMI::enterprises.9.9.189.1.3.2.1.7.10102.1.1 = Counter64: 0
SNMPv2-SMI::enterprises.9.9.189.1.3.2.1.7.10102.2.1 = Counter64: 185716
SNMPv2-SMI::enterprises.9.9.189.1.3.2.1.7.10103.1.1 = Counter64: 0
SNMPv2-SMI::enterprises.9.9.189.1.3.2.1.7.10103.2.1 = Counter64: 127041
SNMPv2-SMI::enterprises.9.9.189.1.3.2.1.7.10104.1.1 = Counter64: 0
SNMPv2-SMI::enterprises.9.9.189.1.3.2.1.7.10104.2.1 = Counter64: 0
SNMPv2-SMI::enterprises.9.9.189.1.3.2.1.7.10105.1.1 = Counter64: 0




And my index shows:

+ Found item [ifIndex='10101'] index: 10101 [from value]
+ Found item [ifIndex='10102'] index: 10102 [from value]
+ Found item [ifIndex='10103'] index: 10103 [from value]
+ Found item [ifIndex='10104'] index: 10104 [from value]
+ Found item [ifIndex='10105'] index: 10105 [from value]
+ Found item [ifIndex='10106'] index: 10106 [from value]
+ Found item [ifIndex='10107'] index: 10107 [from value]
+ Found item [ifIndex='10108'] index: 10108 [from value]
+ Found item [ifIndex='10109'] index: 10109 [from value]

This is from another thread I had open asking for help in graphing this information at http://forums.cacti.net/viewtopic.php?t=24337

Fine, I already supposed it would work this way. Will try to implement it for next release

I asked earlier (In this thread) about being about to walk OID's that use a suffix, and having seen the above 'patch' am wondering if this will solve my issue :)

The problem I have is when I snmpwalk the OID I get the following :-

snmpwalk ps-1.BHM1 -c yyyyy .1.3.6.1.4.1.1991.1.1.2.11.1.1.4
enterprises.1991.1.1.2.11.1.1.4.1.1.1 = Gauge32: 1
enterprises.1991.1.1.2.11.1.1.4.1.1.5 = Gauge32: 1
enterprises.1991.1.1.2.11.1.1.4.1.1.60 = Gauge32: 1
enterprises.1991.1.1.2.11.1.1.4.1.1.300 = Gauge32: 1
enterprises.1991.1.1.2.11.1.1.4.5.1.1 = Gauge32: 1
enterprises.1991.1.1.2.11.1.1.4.5.1.5 = Gauge32: 1
enterprises.1991.1.1.2.11.1.1.4.5.1.60 = Gauge32: 1
enterprises.1991.1.1.2.11.1.1.4.5.1.300 = Gauge32: 1
enterprises.1991.1.1.2.11.1.1.4.9.1.1 = Gauge32: 0
enterprises.1991.1.1.2.11.1.1.4.9.1.5 = Gauge32: 0
enterprises.1991.1.1.2.11.1.1.4.9.1.60 = Gauge32: 0
enterprises.1991.1.1.2.11.1.1.4.9.1.300 = Gauge32: 0
enterprises.1991.1.1.2.11.1.1.4.10.1.1 = Gauge32: 0
enterprises.1991.1.1.2.11.1.1.4.10.1.5 = Gauge32: 0
enterprises.1991.1.1.2.11.1.1.4.10.1.60 = Gauge32: 0
enterprises.1991.1.1.2.11.1.1.4.10.1.300 = Gauge32: 0

Now the index values in this case are the 1,5,9 &10, but these are then followed by a .1 and then the .1,.5,.60 &.300 represent 1,5,60 or 300 second usage.....

Is there a way of using the above 'patch' and the <oid_suffix> that I can get this to work at last ?

Thanks....

I had the same problem as many in this thread. First I needed a more flexible use of REGEX and second my Indexes are not at the end of the OID.

I opened a feature request and also wrote a patch to allow for several enhancements regarding the issues discussed in this thread.

See the following discussion


http://forums.cacti.net/about26851.html


I added the following functions to SNMP Query Indexed

1. Added a new field <oid_index_filter> which accepts a REGEX to filter only those OID that effectively match (<oid_index_parse> only parses the OIDs but keeps all records returned by the SNMPWALK even if the REGEX does not match). This is useful to filter OIDs to keep only one with the interesting Index.

2. Added a new field <index_parse> which can be used in input and output fields. The result is that instead of joining the content of <oid> and the index it accepts a REGEX in <index_parse> which is then applied to the index and uses <oid> as the replacement string. You can use as many groups you want in the REGEX and using the \1, .. \9 to insert the matched strings at any place in the <oid>, not only the end. My patch has only support for the get method and not for the walk method.

3. Added a new field <string> which can be used in to create an arbitrary text.

The code still uses ereg_replace, I have not really seen any advantage of using preg_replace although it could be done.

Currently we are using these features to pull all G.SHDSL Counters (Near and Far end) with one query. Patches required are attached here.
