Did you get these to work?

I am trying them on a ESXi4 box with SNMP enabled and get these errors:

01/04/2010 09:13:21 AM - CMDPHP: Poller[0] Host[34] DS[545] WARNING: Result from CMD not valid. Partial Result: U
01/04/2010 09:13:21 AM - CMDPHP: Poller[0] Host[34] DS[533] WARNING: Result from SNMP not valid. Partial Result: U

SNMPWALK results in this:

SNMP doesn't work with the free license. You can enable it though, with this trick http://salawank.performance-weaver.com/?p=66

However, the templates originally posted to this thread will not work. They depend on the check_esxi3.pl script, which I can't find anywhere, and then function through the API - not via SNMP.

It looks like http://docs.cacti.net/usertemplate:graph:vmware:esx should work with ESXi v4.

I've enabled the SNMP as it says in the link above (note: try esxcfg-snmp.pl instead of vicfg-snmp.pl), and cacti sees that SNMP is talking on the server, but no queries can retrieve any data.

I think that ESXi is crippled in this way...

Enabling SNMP and SSH on Esxi

Post by neop26 »

Just finished writing a blog post on enabling ssh and snmp for esxi both via SSH or RCLI

ESXi 4.0 actually enabled on my system, I got full tree with .1.3.6.1.4.1.6876 by snmpwalk:
[root@cacti script_server]# snmpwalk -v1 -c public x.x.x.x .1.3.6.1.4.1.6876
SNMPv2-SMI::enterprises.6876.1.1.0 = STRING: "VMware ESXi"
SNMPv2-SMI::enterprises.6876.1.2.0 = STRING: "4.0.0"
SNMPv2-SMI::enterprises.6876.1.4.0 = STRING: "164009"

but all templates I found work abnormal

According to my research SNMP in ESXi 4.x provides no statistically useful information.

I have enabled SNMP on my ESXi based on this article:
http://wellytonian.com/2010/03/enabling ... 4-vsphere/

downloaded MIBs from here:
http://downloads.vmware.com/d/info/data ... vers_tools

I have then loaded all MIBs into a MIB browser and started poking around, only to find that all useful data (mem usage, cpu usage, interface statistics) are all in VMWARE-OBSOLETE-MIB.mib. Which based on this "VMWARE-OBSOLETE-MIB.mib -- load if you have previous versions of ESX prior to ESX 4" from Readme, does not mean anything good.

All snmp based templates I have been able to find rely on VMWARE-OBSOLETE-MIB.mib

Then I found this document:
http://www.vmware.com/pdf/vsp_4_snmp_config.pdf
Which basically states that there is a possibility to gain access to standard Linux SNMP information (HOST‐RESOURCES‐MIB) via NET-SNMP, but this seems to be limited to ESX only.

So this seems to be a dead end.

I just did a fresh install of ESXi 4.1, and made sure to configure snmp *BEFORE* installing my license key - in this way, it's running in full-feature trial mode.

I was able to use the various howtos and RCLI to configure snmpd (http://wellytonian.com/2010/03/enabling ... 4-vsphere/ works).

Now when I point cacti at that server, I'm at least getting network interfaces. I'm not able to get CPU or memory information yet, but that may just be a matter of finding the right OID.

Unfortunately looking at the MIB's (http://pubs.vmware.com/vsp40/admin/wwhe ... ingle=true) there doesn't seem to be an OID for CPU usage. Rather unfortunate.

What I am quite curious to find out is if snmp will keep working once i go into "free mode". I have read elsewhere that it WILL work in "free mode" IF you configure it BEFORE you install your "free mode" license!

This whole thing is quite frustrating; all I want is a graph of CPU usage and a graph of Memory usage.

Re: Monitor VMware ESXi?

Post by anglet »

This is what i've done so far:
  • Install vmware vcli in client
  • Import ESXi host_template
  • Copy esxi_cpu.pl esxi_mem.pl esxi_net.pl esxi_vmfs.pl in scripts/
  • Copy check_esx3.pl in scripts/
I've had to install this perl libraries:

yum install perl-Params-Validate
yum install perl-Nagios-Plugin perl-Nagios-Object

To check Vmware CLi is working:

/usr/lib/vmware-vcli/apps/general/connect.pl --server 10.57.223.161 --username root --password PASS
To check op5 check_esx3.pl is working:

./check_esx3.pl -H 10.57.223.161 -l mem -s usage -u root -p PASS

To check ESXi wrapper:

./esxi_net.pl 10.57.223.161 PASS

The last one doesn't work for me....

My mistake: I had cacti installed in a path diferent to /var/www/cacti so this scripts didn't work.

Code: Select all

$response = `/var/www/cacti/scripts/check_esx3.pl -H $ARGV[0] -u root -p $ARGV[1] -l mem -s usage`;
chomp $response;
($load) = ($response =~ /mem_usage=(\d+\.\d\d)\%/);
print "$load\n";

Finally I have it working, but i had to edit the wrappers.

Import ESXi host template

Console > Import Templates

Install and test vmware API

Test vmware api:

/usr/lib/vmware-vcli/apps/general/connect.pl --server SERVER --username root --password PASS

Test check_esx3

./check_esx3.pl -H IP ADDRESS-u root -p PASS -l cpu -s usagemhz

Test ESXi scripts

Check correct path: /var/www/cacti

./esxi_net.pl IP_ADDRESS PASSWD
./esxi_cpu.pl IP_ADDRESS PASSWD
./esxi_mem.pl IP_ADDRESS PASSWD

I attach my modified scripts.

Configure devices and create graphs.
