SNMP and OIDs

[spoonman]

Guys.......Here is an issue I can't seem to fix... from my cacti server ( linux ) i can snmpwalk a device and get a valid return. But when I try to graph that same OID i get error...U in debug for result???

snmpwalk -v 1 -c ***** 172.*.*.* .1.3.6.1.4.1.674.10893.2.100.3.1.1.23
SNMPv2-SMI::enterprises.674.10893.2.100.3.1.1.23.1 = INTEGER: 3


Here is my Debug from cacti.log....

04/25/2006 01:06:14 PM - CACTID: Poller[0] DEBUG: SQLCMD: insert into poller_output (local_data_id,rrd_name,time,output) values (1222,'door_state','2006-04-25 13:05:03','U')
04/25/2006 01:06:14 PM - CACTID: Poller[0] Host[92] DS[1222] SNMP: v1: 172.*.*.*, dsname: door_state, oid: .1.3.6.1.4.1.674.10893.2.100.3.1.1.23, value: U

Does Cacti use snmpwalk or snmpget??? if i use snmpget i dont get the same result??

Thanks.

This WORKS......

snmpgetnext -v 1 -c ***** 172.*.*.* .1.3.6.1.4.1.674.10893.2.100.3.1.1.23
SNMPv2-SMI::enterprises.674.10893.2.100.3.1.1.23.1 = INTEGER: 3


snmpwalk -v 1 -c ***** 172.*.*.* .1.3.6.1.4.1.674.10893.2.100.3.1.1.23
SNMPv2-SMI::enterprises.674.10893.2.100.3.1.1.23.1 = INTEGER: 3




This doesn't......

snmpget -v 1 -c ***** 172.*.*.* .1.3.6.1.4.1.674.10893.2.100.3.1.1.23
SNMPv2-SMI::enterprises.674.10893.2.100.3.1.1.23.1 = INTEGER: 3
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: SNMPv2-SMI::enterprises.674.10893.2.100.3.1.1.23

YOu should change .1.3.6.1.4.1.674.10893.2.100.3.1.1.23 to .1.3.6.1.4.1.674.10893.2.100.3.1.1.23.1as the snmpwalk returns data only for the latter.

Reinhard..........Thanks for that insite...that worked perfectly....I now have a graph with data on it.
Why do you suppose if i manually from snmpwalk from my cacti server cli it reports the correct info.....but when cact runs it .....no go. Wonder why adding the 1 to the end makes it work??

Thanks again.

[gandalf]

See you own post, but with more care:

snmpwalk -v 1 -c ***** 172.*.*.* .1.3.6.1.4.1.674.10893.2.100.3.1.1.23nothing appended
SNMPv2-SMI::enterprises.674.10893.2.100.3.1.1.23.1 = INTEGER: 3

So no magic here
Reinhard

[spoonman]

I'll be!!!! Thanks for pointing that out!!!! Guess i just assumed it was the same since i didnt have the 1 at the end at cli ///

Thanks again.

Hi, I think I have a similar problem:

snmpget -v1 -c ******** 192.******** enterprises.3224.16.1.2.0
SNMPv2-SMI::enterprises.3224.16.1.2.0 = INTEGER: 2

Cactid output:

CACTID: Host[3] DS[271] SNMP: v1: 192.*****, dsname: snmp_oid, oid: enterprises.3224.16.1.2.0, value: U

It's funny, because I have a similar device in the network, and it's retrieving the data and graphing it prefectly:

CACTID: Host[4] DS[276] SNMP: v1: 192.*****, dsname: snmp_oid, oid: enterprises.3224.16.1.2.0, value: 2

Thanks!

[gandalf]

Easiest way: Just copy out the snmpget statement and run it via command line, one time for the device without problems and once for the other. This should help

Hi,

From the command line everything works fine:

The problematic device:
#snmpget -v1 -c **** 192.****7 enterprises.3224.16.1.2.0
SNMPv2-SMI::enterprises.3224.16.1.2.0 = INTEGER: 2

The "good" device:
#snmpget -v1 -c **** 192.****8 enterprises.3224.16.1.2.0
SNMPv2-SMI::enterprises.3224.16.1.2.0 = INTEGER: 2

Also, I've tried to create two more datasources retrieving the same oid, and they start returning weird values:

From Cactid output:

CACTID: Host[3] DS[271] SNMP: v1: 192.****7, dsname: snmp_oid, oid: enterprises.3224.16.1.2.0, value: 158062464
CACTID: Host[3] DS[513] SNMP: v1: 192.****7, dsname: snmp_oid, oid: enterprises.3224.16.1.2.0, value: 69
CACTID: Host[3] DS[514] SNMP: v1: 192.****7, dsname: snmp_oid, oid: enterprises.3224.16.1.2.0, value: U
CACTID: Host[4] DS[276] SNMP: v1: 192.****8, dsname: snmp_oid, oid: enterprises.3224.16.1.2.0, value: 2

I've also tried to delete the datasources, and create them again from scratch, getting the same result...

All of this started when I migrated from cmd.php to cactid. Everything works fine except this single device.

Thanks for your help!

Hmm, some time ago I had a similar problem with cactid. This was solved by TheWitness at least in SVN. Is it possible for you to try the latest SVN code? See http://cacti.net/svn.php. Else, please pm TheWitness

Thanks!

I'll try the lastest SVN then, I hope today or next Monday

Thanks for your help!

Hi again,

I've tried to compile from the sources, and it seems to go well, but when I run cactid from the cli, after polling nearly all the oid's of the first host, I get a 'Segmentation Fault'. I've also noticed that if I install the last version available in rpm for FC3, I get the same error

Thanks!

[gandalf]

So please report this via pm to TheWitness or post a bug at http://bugs.cacti.net
Reinhard

[TheWitness]

Please post your stackdump file. Also, do you get the same results if you poll with numeric OID's? Once you have posted the stackdump, I will provide additional instructions.

Thanks,

TheWitness

[Grogman]

Hi Witness,

I've tried the numeric OID's, getting the same result:


From the CLI:
# snmpget -v1 -c **** 192.***7 1.3.6.1.4.1.3224.16.1.2.0
SNMPv2-SMI::enterprises.3224.16.1.2.0 = INTEGER: 2
# snmpget -v1 -c **** 192.***8 1.3.6.1.4.1.3224.16.1.2.0
SNMPv2-SMI::enterprises.3224.16.1.2.0 = INTEGER: 1

From Cactid:

CACTID: Host[3] DS[516] SNMP: v1: 192.***7, dsname: snmp_oid, oid: 1.3.6.1.4.1.3224.16.1.2.0, value: U
CACTID: Host[4] DS[276] SNMP: v1: 192.***8, dsname: snmp_oid, oid: 1.3.6.1.4.1.3224.16.1.2.0, value: 1

Regarding the stackdump, can you tell me where to look for it? I've looked for it in the directory as the binary, but didn't found it

Thanks!
