ACE SNMP OIDs

Good afternoon
I need your help.
I´m trying to extract some information through SNMP queries to my ACE, specifically, in each serverfarm the rserver weight state (if he is OPERATIONAL or OUTOFSERVICE, etc), and the number of current conns he has.
Now I´ve been trying to find the Cisco OIDs to extract that info but with no luck.
I´ve managed to find out how to find the Hex-STRING that corresponds to each rserver.
For example, the rserver 10.134.53.111 which converted to hexadecimal is 0A 86 35 6F:
snmpwalk -v 2c -c dsws3g! 192.168.1.1 1.3.6.1.4.1.9.9.470.1.1.1.1.4 | grep 0A 86 35 6F
iso.3.6.1.4.1.9.9.470.1.1.1.1.4.9.8.69.83.66.45.70.69.48.49 = Hex-STRING: 0A 86 35 6F
After that I´ve searched in the CISCO cesRealServer table for the number of current conns and the correspondent OID concatenated with the rserver string discovered previously returns me the number of conns the rserver has:
snmpwalk -v 2c -c dsws3g! 10.167.2.227 1.3.6.1.4.1.9.9.470.1.1.1.1.19.9.8.69.83.66.45.70.69.48.49
iso.3.6.1.4.1.9.9.470.1.1.1.1.19.9.8.69.83.66.45.70.69.48.49 = Counter64: 99
The problem is that this rserver is being used in 2 different serverfarms, and the number of connections it returns me does not correspond to the number of connections of a specific farm...it seems to be adding the number of conns it currently has on both serverfarms.
How can I filter the results through each serverfarm?
I´ve found how to discover the correspondent OID to each serverfarm:
snmpwalk -v 2c -c dsws3g! 10.167.2.227 1.3.6.1.4.1.9.9.161.1.4.2.1.2.9 | grep TEST
iso.3.6.1.4.1.9.9.161.1.4.2.1.2.9.76 = STRING: "TEST-HTTP"
iso.3.6.1.4.1.9.9.161.1.4.2.1.2.9.77 = STRING: "TEST-HTTPS"
but I don´t know how to match all this info in order to get the data I need.
I apreciate your input.

Ok, so after a couple of hours searching for the right OID tree I finally found it: cesServerFarmRserverTable:
http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?local=en&translate=Translate&objectInput=1.3.6.1.4.1.9.9.470.1.1.3.1#oidContent
Here you can get the data you need from a rserver from a specific serverfarm

I am trying to build a basic TCL skeleton script that reads a remote SNMP OID and displays the value on the screen.

I am trying to build a basic TCL skeleton script that reads a remote SNMP OID and displays the value on the screen.
I don't want it to be an EEM Event, I just want to run it from the (tcl)# prompt.
So I guess I'm asking if you can use cli_exec and other commands in the "namespace import ::cisco::eem::*" in a normal non-EEM script - can I do that?
This is the error I get:

If you don't want an EEM policy, then don't use any of the EEM constructs. Instead, all you need is this:
set output [exec "snmp get v2c 192.168.1.100 public timeout 1 oid 1.3.6.1.2.1.1.1.0"]puts $output

The cisco snmp oids do not work, I can't get cpu or memory data.

Hello. I want to monitor the cpu and memory usages on my cisco devices using snmp. I found the snmp oids related to cpu in the following page :
http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a0080094a94.shtml
I just copy the table here:
But the oids in the table do not work on my devices. For example, I have a cisco 3550 switch with the ip 192.168.1.211, version 12.2(25)when I want to get the informations about the oids up in the table, I got these results:
It shows that the oids cisco given up in the table are not existed in my 3550 switch's MIB. More weird is that when i add a number "1" to
the end of the oid cisco given, I can get some meaningless data for some unkonwn item names like "entreprises.x.x".
For most mib items, the snmp oids work well on my switch. For example, the following graph shows the interface out rate of the swtich:
I think the essence is when I executed the following command:
in all the output results, there's not any item relevant with "cpu" or "memory", but most other items are ok, such as interfaces, as shown below:
IF-MIB::ifDescr.47 = STRING: FastEthernet0/39
IF-MIB::ifDescr.48 = STRING: FastEthernet0/40
IF-MIB::ifDescr.49 = STRING: GigabitEthernet0/1
IF-MIB::ifDescr.50 = STRING: GigabitEthernet0/2
IF-MIB::ifDescr.51 = STRING: Null0
IF-MIB::ifDescr.52 = STRING: Vlan1
IF-MIB::ifType.1 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.2 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.3 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.4 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.5 = INTEGER: ethernetCsmacd(6)
So why the cisco given oids won't work on my cisco switch, and how can I get the datas I want? Anyone has some advices? Thanks in advance!
In case the pictures I inserted missing, I attach my problem in the doc.

Have you looked at this previous discussion:

Snmp oids for the command "show counters interface intx/y delta"

Hello,
I have a question about SNMP OIDs for the command "show counters interface intx/y delta" on Catalyst6500. The customer wants to create graphs for the following values:Overruns, qos0Outlost, InErrors, OutErrors, InDiscards, OutDiscards etc..
Is possible to get these values using SNMP??
Thank you
Roman

Thank you, Dan. These OIDs are for the output from the command "show interface int x/y". But I think, that these OIDs are not for the command "show interface int x/y delta".

Hello –
I received a reply from the developer of the script, and listed below is the new code that was suggested:
#!/bin/bash
value=`snmpwalk $1 -v1 -c $2 .1.3.6.1.2.1.25.1.5.0 | cut -d " " -f4`
if [[ value -gt $3 ]]
then
echo " $value Users Online, Critical!"
retval=2;
else
     if [[ $value -gt $4 ]]
           then
           echo " $value users online, Warning!"
           retval=1;
           else
           echo " $value Users online, fine."
           retval=0;
           fi
fi
exit $retval;
I checked the server in question, and there were two, 2, user logins active on the system. I ran the snmpwalk command, and the output was the following:
HOST-RESOURCES-MIB::hrSystemNumUsers.0 = Gauge32: 15
I then modified the script to include the above text, and ran it again. The output was the following:
15 users on line, Normal.
For some reason, the value of 12 appears to be that for no users logged into the system. I am not sure why that is the case.
If nothing else, progress has been made with the modification of the script. The snmp service that I have installed on the server is that which came bundled as a
feature with the server. The only thing that was not installed was the SNMP WMI Provider option.

SG-500 - SNMP OID for CPU Load?

Hello,
i have several SG500 (Standalone and stacked). How can i get the CPU Load via SNMP? Who knows the correct SNMP OID for CPU Load?
In the MIB which are provided as download a wasn't able to find the correct OID.

Hello,
There are three OIDs available for CPU usage:
CPU utilization for 5 seconds
.1.3.6.1.4.1.9.6.1.101.1.7.0
CPU utilization for 1 minutes
.1.3.6.1.4.1.9.6.1.101.1.8.0
CPU utilization for 5 minutes
.1.3.6.1.4.1.9.6.1.101.1.9.0
This came from a scrap note I had in an e-mail, so I am not exactly sure where this information is originally.
Let me know if that works for you,

SNMP OID on Catalyst 3750G & 3650G

Hallo guys,
we have a couple of 3750Gs and sveral 3650Gs in my company lan, and I'm looking for the SNMP OIDs supported with which the very basic status of these switches can be retrieved. I mean generic status like the switch is being active, or experiencing technical error etc...
I was advised to take 1.3.6.1.2.1.4.1.0 (IPForwarding), but I'm not sure if it is the right one. I'd appreciate if someone can give me a hint..
Thank you!
Li Lu

Your request is pretty generic. There are a lot of OIDs which can provide device health. You might want to start with ifInOctets, ifOutOctets, ifInErrors, and ifOutErrors. Those will give you per-port byte and error counts in both the ingress and egress directions.
As for whole-device help, take a look at the moduleTable from the CISCO-STACK-MIB. The object moduleStatus will tell you the status of the fixed switch itself.

What snmp OID to use to monitor control-plane of router

Hi there!
I've applied policy-maps on control-plane, based on cisco recomandation.
Now i need to know, what snmp OID i've to use to monitor them (i'm using zabbix)
Let me know.
Regards!

If you are using IOS which uses a policy-map to configure Control Plane Policing then you are asking in the wrong place as this forum is for IOS-XR not IOS but you can poll objects in the CISCO-CLASS-BASED-QOS-MIB::cbQosPoliceStatsTable (for example cbQosCMDropByte64, cbQosPoliceExceededByte64, cbQosPoliceConformedByte64).
If you mean you have changed the LPTS policers to help protect the control-plane in IOS-XR then I believe there is currently no support for polling the counters via SNMP.

Issue: looking for a snmp OID to poll power supply status (Inbuilt Power Supply - no redundant power supply in this scenario). Possibly what we see in show environment.
CSE analysis:
I tried using the OIDs belonging to CISCO-ENTITY-FRU-CONTROL-MIB , like cefcFRUPowerOperStatus and cefcFRUPowerAdminStatus but it didn’t return anything.
NOTE: I have done all the snmp walks from the Linux server. Do I doubt it’s something to do from the snmp manager side.
Couple of observations. The CISCO-ENTITY-FRU-CONTROL-MIB talks about the field replaceable power supplies, so I doubt if it’s going to return the value for inbuilt power supply.
Second, I noticed that there are snmp traps supported for power supply and threshold setting. See configuration below. Is it that only traps works for power supply and environment related details?
Snmpwalk on cefcFRUPowerStatusEntry returns nothing:

Hi
I've got an ASA with redundant power supplies. An ASA5585. So I have the need to monitor them. :-) So how can we do it?
Also I've made a SNMP-Walk through the ASA v8.4(2)8 and it doesn't show up any ENV-MIB values. The
1.3.6.1.4.1.9.9.13 tree is not available. Are you shure it's available on the ASA?
Funny is also that the command "show snmp-server oidlist" from the 8.4 configuration guide is not available on the real CLI. I think the documentation guys were faster than the coders. ;-)
Kind regards

ACE module - should 'sh serverfarm' and the SNMP OID 'slbVServerNumberOfConnections' show the same value?

I've recently begun to notice that the current connections value displayed by the ACE when using the 'sh serverfarm' command isn't matching up with the value returned by a custom MIB poller I'm using to return the value of the associated 'slbVServerNumberOfConnections' OID when I had assumed that they represented the same thing?
As an example at the moment the ACE is showing 400 current connections for a particular serverfarm but my customer poller is returning 250?
I'd noticed this behaviour whilst the ACE was running software version A2(1.6a) and had hoped that an upgrade to A2(2.3) might fix it but it hasn't - assuming it's a bug as opposed to just my misunderstanding of what value 'slbVServerNumberOfConnections' is actually returning?
Can anyone explain what I'm seeing or am I polling the wrong OID?
Thanks in advance
regards
Matthew

What about the 'show conn' ? do you see 400 or 250 concurrent connections ?
What about 'sho service-policy'
The OID refers to the VIP not the serverfarm.
Also the show serverfarm is known to display incorrect information
CSCtc94844: ACE: show serverfarm current connection counter incorrect
The fix will be in A2(2.4)

ACE SNMP cesRserverTotalConns "There is no such variable name in this MIB"

I have an ACE 4710 appliance currently running version A3(2.6), though earlier revisions had the same behavior. I am able to query some parts of the CISCO-ENHANCED-SLB-MIB, but others result in "(noSuchName) [t]here is no such variable name in this MIB." For instance, I can successfully `snmpwalk` cesRserverOperStatus, cesRserverStatechangeDescr, and several other OIDs, but not cesRserverTotalConns, cesRserverFailedConns, nor cesRserverCurrConns. I've also tried `snmpget` of specific real servers with the same results. Things like OperStatus and IpAddress work, but Total, Failed, and CurrConns do not.

I have reviewed the Cisco ACE 4700 Series Appliance Administration Guide - Configuring SNMP document and read the "SNMP Limitations" which states "[i]f an SNMP MIB table has more than one string index that contains more than 48 characters, the index may not appear in the MIB table when you perform an SNMP walk. According to SNMP standards, the SNMP requests, response, or traps cannot have more than 128 subidentifiers."
If that is the reason this doesn't work, could someone please more adequately explain the difference between querying the OperStatus versus the CurrConns when the OID I'm querying in each instance is the exact same length? And is there anything that I could change in my configuration so that I can query connection information with SNMP?
If that documented SNMP limitation is not the reason that those particular queries fail, does anyone have any idea what the problem might be and/or next steps I should take in troubleshooting and resolving the issue?

Are you using snmp v1? If so, please try snmp v2.
The following is the test result in my lab.
### snmp v1
lin168:~# snmpget -c cdn -v 1 1.164.0.51 .1.3.6.1.4.1.9.9.470.1.1.1.1.17.1.3.115.118.49

### snmp v2
lin168:~# snmpget -c cdn -v 2c 1.164.0.51 .1.3.6.1.4.1.9.9.470.1.1.1.1.17.1.3.115.118.49
SNMPv2-SMI::enterprises.9.9.470.1.1.1.1.17.1.3.115.118.49 = Counter64: 251118
snmpwalk also works with snmp v2 as below.

If you use snmp v1, the behavior looks expected since syntax is not convertable to SMIv1 as below.
It means you have to use snmp v2 if you want to get Total, Failed, and CurrConns MIBs.

Is there a single snmp oid for flash and dram ?

Does a single univeral oid (or 1 for flash and one for dram) exist that will provide total amount of flash and total amount of dram across all chassis families ?
Thanks
