SNMP Item not working for Cisco ME-3400-24TS-A

[Nehemoth]

Trying to monitor a switch using SNMP.

Followed up the documentation about how to create an item for a SNMP agent which can be found here.

After several tries, I am still not been able to see/gather the status for the desired information.



Did a snmp walk

snmpwalk -v 2c -c HEADEND MY_Switch_IP_Address

It gave me a lot of info from where I took what interest me

SNMPv2-SMI::mib-2.47.1.2.1.1.8.11 = STRING: "vlan-825"
SNMPv2-SMI::mib-2.47.1.2.1.1.4.11 = STRING: "HEADEND@825"
SNMPv2-SMI::mib-2.47.1.2.1.1.2.11 = STRING: "vlan825"
SNMPv2-SMI::mib-2.47.1.1.1.1.7.1008 = STRING: "FastEthernet0/2"
SNMPv2-SMI::mib-2.47.1.1.1.1.2.1007 = STRING: "FastEthernet0/1"
SNMPv2-SMI::mib-2.47.1.1.1.1.2.1002 = STRING: "ME-3400-24TS-A - Fixed Module 0"
SNMPv2-SMI::mib-2.47.1.1.1.1.2.1003 = STRING: "ME-3400-24TS-A - Power Supply 0"
SNMPv2-SMI::mib-2.47.1.1.1.1.2.1004 = STRING: "ME-3400-24TS-A - Fan 0"

from where I took one

snmpget -v 2c -c HEADEND -On 172.24.31.199 SNMPv2-SMI::mib-2.47.1.1.1.1.2.1004

which gave me

.1.3.6.1.2.1.47.1.1.1.1.2.1004 = STRING: "ME-3400-24TS-A - Fan 0"

With that information I went to the host items, create a new one as follows:

Name: SNMP:NAME
Type: SNMPv2 Agent
Key: SNMPv2-SMI
SNMP OID: .1.3.6.1.2.1.47.1.1.1.1.2.1004
SNMP Community: My_COMMUNITY
Type of Information: Numeric (unsigned) [also I tried with numeric {float}]

Is there anything wrong with that?

.1.3.6.1.2.1.47.1.1.1.1.2.1004 = STRING:

and

Type of Information: Numeric

?

Nice way to makes me see the error but I tried character (and even log and text) but I got the same result.
Having said that, maybe I need to look out for the same item but with another type of data.

Thank you for the answer.

And actually what error do you get (the red icon in the info field of the problem data element)?
What is written in the server logs?

I believe you put me in the right path.
After the previous post I change the item to be monitored, now I'm getting some information.

my command

snmpget -v 2c -c HEADEND -On My.IP IF-MIB::ifInOctets.10004

what I'm getting from the cli

.1.3.6.1.2.1.2.2.1.10.10004 = Counter32: 410041180

How I created the item

 Type: SNMPv2
Key: SNMP-InOctets
SNMP OID: .1.3.6.1.2.1.2.2.1.10.10004
SNMP Community: My_COMMUNITY
Type of Information: Numeric (unsigned)

and finally what I'm getting (graphically) : 410041180

So as right now I believe my issue it's understanding what I'm monitoring.
After all a hardware can have only 2 values, working or not / there or not.

The documentation it's great so I believe I will continuing digging and see how can I find the desired information, if this case to know if a port it's working or not.

@Hamardaban really appreciate the help
