Monitor Vmware ESX

[wica128]

@Khue did you install nagios?

I have nagios on the same server as cacti.

@wica128

I did not realize that was a requirement for this setup. I must have missed something. I am probably going to abandon this. Seems like too many moving parts.

Hi all,

I try to use this ESXI tepmlete to monitor VMware vSphere5, But when I use the Data Query Debug Information get the foloowing result
----------------------------------------------
Data Query Debug Information

+ Running data query [8].
+ Found type = '6' [Script Query - Script Server].
+ Found data query XML file at '/var/www/html/resource/script_server/vmware_cpu.xml'
+ XML file parsed ok.
+ Invalid field <index_order>vmDisplayName:vmID:vmIndex</index_order>
+ Must contain <direction>input</direction> fields only

-----------------------------------------------------
I tey to to use MIB brower to watch teh MIB mwVMIdx OID : 1.3.6.1.4.1.6876.2.1.1.1 show can't accessble
snmpwalk -c public -v2C 192.168.11.216 .1.3.6.1.4.1.6876.2.1.1.1 show no such object available on this agent at this OID....

Should I use the SNMP V3 to get this OID value, otherwise teh data query can't get teh right value~~

It's not a problem of SNMP Version used to get data, but the issue is related to an OID declared OBSOLETE from Vmware.
When you launch this query you ask to Vsphere 5 to send VM CPU Usage (oid .1.3.6.1.4.1.6876.3.1.2.1.3), but this information is not more provided by Vmware (see this article http://pubs.vmware.com/vsphere-50/index ... F0E50.html). So this is the reason why query doesn't work anymore.
Now the question is how to get Cpu Utilization without this OID ? I think we need to change the script, but i'am not a programmer and my knowledge is really bad.

You can't. VMware has dropped support of SNMP. You have to use CIM/SMASH in order to obtain hardware status, etc. You have to use their API in order to obtain "higher level" performance stats like CPU utilization, Memory utilization, Disk IO, etc. AFAIK Cacti doesn't have a means for doing either of those.

the vmware is too arrogant!

Hi. So, if I understand, it's impossible to monitore ESXi 5.1 with SNMP ? (without add third party)

[trungmv]

Hi all,

I using vmware_esx_cacti_0.8.7[x]-20091009.zip from Dickys, every step import is fine.

But when create graphics step i have some errors:

1. Data query can not get some information from VMware:

2. I run data query in debug mode one of them and it's appear:

CPU get:


My system:
cacti version 8.8.b
OS: Centos 5.8
Mysql : 5.5.38-cll-lve
ESX: 4.0

Any help is appreciate.

I think you have an issue with the snmp configuration on the esx server...

What is the output from

Code: Select all

snmpwalk -v 2c -c <your community> <your host> .1.3.5.1.4.1.2021.9.1.1 [code]

Maybe the OID is wrong or something like that.

[trungmv]

Hi um3n,

I checked with your OID but not get data, it's appear :

SNMPv2-SMI::org.5.1.4.1.2021.9.1.1 = No Such Object available on this agent at this OID

If i only using:

Code: Select all

snmpwalk -v 2c -c <My community> <My IP server> 

, will show many information.

These are snmp file that i have had build:
snmp.xml:

Code: Select all

<config>
  <snmpSettings>
    <communities>public</communities>
    <enable>true</enable>
    <port>171</port>
    <targets>127.0.0.1@162/public</targets>
  </snmpSettings>
</config>

snmpd.conf:

Code: Select all

load  99 99 99
syslocation Serverraum
syscontact  "ESX Administrator"
rocommunity  public
view systemview included .1.3.6.1.4.1.6876
proxy -v 1 -c public 127.0.0.1:171 .1.3.6.1.4.1.6876

If i wrong OID, how to get the right OID?

Any help is appreciated,

Are these something wrong with my file?

Any help is appreciated,

Hey trungmv,

i think there is a problem in your script, but my php skills are not very high
Please post the entire script in a Code block? Maybe i can get some information...

To the oids...

Please check these oids with a snmpwalk... then you will get an error if the are the wrong oids.

Code: Select all

snmpwalk -v 2c Host -c SNMP-Community 1.3.6.1.4.1.6876.3.3.1.1

-v 2c is your securitylevel.

Hi all,

I can not found any other OID excepted .1.3.6.1.4.1.6876 in my vmware.

Are these templates only for old cacti version or whatever?

Currently, i can not get all data from template on forum

Any help is appreciated,
