having issue with monitor VMware 5.1 on zabbix 5.2

[Arul]

Hi all,

I am configuring zabbix 5.2 to monitor VMware 5.1. Created new host with agent interface with "Template VM VMware" template configured Macros :
{$PASSWORD} => <my password>
{$USERNAME} => <my username>
{$URL} => https:/<MY IP>/sdk

Not getting any latest data.

With increase Debug level, getting the following on log:

End substitute_simple_macros_impl() data:'https://ip-address/sdk'
End of substitute_key_macros_impl():SUCCEED data:'vmware.eventlog[https://ip-address/sdk]'
In substitute_simple_macros_impl() data:'{$USERNAME}'
In DCget_user_macro() macro:'{$USERNAME}'
End of DCget_user_macro()
End substitute_simple_macros_impl() data:'zabbix'
In substitute_simple_macros_impl() data:'{$PASSWORD}'
In DCget_user_macro() macro:'{$PASSWORD}'
End of DCget_user_macro()
End substitute_simple_macros_impl() data:''
In get_value() key:'vmware.eventlog[{$URL}]'
In get_value_simple() key_orig:'vmware.eventlog[{$URL}]' addr:'ip-address'
In check_vcenter_eventlog()
In get_vmware_service() 'zabbix'@'https://ip-address/sdk'
In zbx_vmware_get_service() 'zabbix'@'https://ip-address/sdk'
End of zbx_vmware_get_service():FAIL
End of get_vmware_service()nil)


In log the actual IP of VMware is changed to "ip-address".
Any idea where I am making mistake?

Got stuck, hoping to get some insights.

Dear Arul,

I had some problem with Vmware too, here is what I found during my struggle:
1) if you have a Vcenter you just need to create a Host for your Vcenter then it will discover your Hypervisors and hosts. also it is really important to use de default macro names as they are used in discovery rules.
this link is really helpfull it has lots of tips

2) you can test your URL in Linux by this command to see it actually works curl https:/<MY IP>/sdk, also you should be able to login with your username and password

Kind Regards

[Arul]

Thanks for your kind reply,

For "curl https:/<MY IP>/sdk"
I get :
curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.haxx.se/docs/sslcerts.html

Got new cacert.pem from: https://curl.haxx.se/ca/cacert.pem and pointed its path in /etc/php.ini for "curl.cainfo="
Still continued with same error.

When I tried "-k": "curl -k https:/<MY IP>/sdk" it returned with no output!!
How to proceed

[Cameron94]

You are most welcome,

the output you're getting is actually a good sign, which means your URL is working as it should.
you can also check for error in Monitoring>latest data> then choose your host and check both "show item without data" and "show detail" hopefully you will see an error for simple check items that have failed.
or in Configuration> item check your host items, you will definitely see some error in one of these places.

Regards

It looks like a certificate issue, how can I resolve it.

Hi Arul,
Just saw the post, Thought to add here so that it may help others.
Error “URL using bad/illegal format or missing URL” may also occur if you are using self-signed certificates on the vSphere.

Solution is to download the root CA certificate from the vSphere
Hit this URL in browser- (https://server_dns_or_ip/certs/download.zip).
Press control S
Save the certificate zip file
Unzip and go to certs/win
copy the certificate files into the /usr/share/ca-certificates using zabbix cli
Check once if again it does not work
reconfigure the CA with “dpkg-reconfigure ca-certificates“

[Cameron94]

in my case it didn't cause any problem. I don't have a solution for that.

[Arul]

Your right I am getting "No vmware collector" processes started." Hopefully, it should be resolved by editing the zabbix-server.conf

[Cameron94]

StartVMwareCollectors=? ----> < StartVMwareCollectors < (servicenum * 2)Where servicenum is the number of VMware for example if you have 3 VMware services, set it to 5
VMwareFrequency=60
VMwarePerfFrequency=60
VMwareCacheSize=32M
VMwareTimeout=120

[Arul]

Thanks for guiding.
So far Latest data populated with Event Log, Version and Full Name.
One of the 3 discovery rules " Discover VMware hypervisors" giving error "Cannot create group: invalid group name "" "

Any tips to overcome this issue..

[Cameron94]

you should give it some time to collect the data. I don't know that error

[Arul]

I appreciate the quick response, Thank you very much, I will update the result

[Arul]

The discovery rule "Discover VMware VMs" Populated all VMware host as separate host with discovery rule prefix. Thank you.

Is there any way I can manage the discovered VMs from zabbix dashboard (on / off / restart) ??

[Cameron94]

Great News! it might be possible by using SNMP, but I don't know exactly how to do it.

It's great to be in such an amazing community, though in my case I didn't have any issues so far.
