Trying to do a ifOperStatus map. "no valid data" on SNMP

[daveynihil]

Hi guys,
After seeing the "show off your weathermap" thread I've decided to implement one of those Cisco Chassis ifOperStatus maps and have spend the best part of the morning trying to get it work.

I have no need to log IF status using RRD, so have been following the thread info here http://forums.cacti.net/viewtopic.php?f=16&t=36174 to do the SNMP query from the SNMP DS plugin within weathermap.

I can't get the SNMP query to work however. All I get in the logs is

Code: Select all

04/24/2012 11:47:13 AM - WEATHERMAP: Poller[0] WARNING: [Map 16] TEST-MAP: ReadData: NODE TESTRACKSWITCH_p02, target: snmp:NOTMYSNMPKEY:192.168.1.1:.1.3.6.1.2.1.2.2.1.8.10002:- on config line 54 had no valid data, according to WeatherMapDataSource_snmp

And the node stays coloured yellow.

My SNMP key is fine, and doing an snmpwalk with 2c (and even attempting 1 temporarily) works fine.

Code: Select all

# snmpwalk -v 2c -c NOTMYSNMPKEY 192.168.1.1 1.3.6.1.2.1.2.2.1.8.10002
IF-MIB::ifOperStatus.10002 = INTEGER: up(1)

I'm well and truly stuck now, with no idea where else to look. Can anyone offer me any leads?

Config is :-

Weathermap will always use SNMPv1 - not sure if that will make a difference for you...

Also, try adding a .0 onto the end of the OID. snmpwalk is a bit more flexible than snmpget, and for some OIDs this is required. I didn't think interface status was one of them, though. To be SURE, add -On to your snmpwalk command line, to get the numeric OID that it is returning (it isn't always the same as what you asked for).

Still no joy.

Code: Select all

snmpwalk -v 1 -c  notmykey 192.168.1.1 1.3.6.1.2.1.2.2.1.8.10001 -On

.1.3.6.1.2.1.2.2.1.8.10001 = INTEGER: up(1)

Tried with a leading 0

Tried removing the . from the front of the OID. Same with the end. Just can't get it to get anything it thinks is valid data.

Using SNMPGET instead of SNMPWALK works perfectly as well.

Code: Select all

snmpget -v 1 -c notmykey 192.168.1.1 .1.3.6.1.2.1.2.2.1.8.10002
IF-MIB::ifOperStatus.10002 = INTEGER: up(1)

Can't think of anything else to try now. It seems like the SNMP weathermapdatasource just doesn't like the info it's getting back from the switch.

Code: Select all

ReadData: NODE, target: snmp:notmykey:192.168.1.1:.1.3.6.1.2.1.2.2.1.8.0.10002:- on config line 54 had no valid data, according to WeatherMapDataSource_snmp

Code: Select all

ReadData: NODE target: snmp:notmykey:192.168.1.1:1.3.6.1.2.1.2.2.1.8.10002:- on config line 54 had no valid data, according to WeatherMapDataSource_snmp

Can anyone post any more snippets of working configs that I can compare to my setup? Might have to look at doing this on RRD instead I guess.

With DEBUG logging, you should see more about what values are being fetched...

I think there is actually a problem on this specific OID with SNMPv2 wheathermap DataSource, it might a corner case but it seems to work fine with nw datasource for snmpv1 version.

These are examples by running snmpwalk from the box

Code: Select all

.1.3.6.1.2.1.2.2.1.8.10102 = INTEGER: down(2)

Code: Select all

.1.3.6.1.2.1.2.2.1.8.10103 = INTEGER: up(1)

Now, if I set the TARGET to use snmp instead of snmp2c it works fine and you can tell there is something different in the way they both parse the output because I've set

Code: Select all

LABEL {node:this:snmp_in_raw}

and when I use snmpv1 I get 1 or 2 but when I use v2 I get up or down.
