issues with vcenter 6.0 and esxi 5.5 #29

Closed hetzbh closed 8 years ago

hetzbh commented 8 years ago

Hi,

I just downloaded and install vmbix. (CentOS 7.1, zabbix 3.0 latest). I didn't set the enable UUID at the beginning and I see the vm's but those vm's have no data in them in zabbix, I don't see any graphs for vm's, and no latest data or anything.

I tried to enable UUID on vmbix but then I'm getting errors that my esxi machine is not found (I'm monitoring the vcenter, not the specific esxi host). Zabbix show's the esxi as 'not connected' although it clearly is. Example:

2016-06-21 01:42:28,048 INFO  [Thread-52] [VmBix.java:3390] thread  closed, collecting data in 0 threads
2016-06-21 01:42:31,021 INFO  [Thread-53] [VmBix.java:3347] thread created, collecting data in 1 threads
2016-06-21 01:42:31,069 WARN  [Thread-53] [VmBix.java:1365] No host named 'esxi1.xxx.com' found
2016-06-21 01:42:33,097 INFO  [Thread-53] [VmBix.java:3390] thread  closed, collecting data in 0 threads

So I have 2 questions:

  1. Is there a way that vmbix can show the data on the vm's (disk, network etc) as well as graphs?
  2. If I use the module (I don't at the moment), will I need to install Zabbix agent on each vm in order to get the data?

Thanks

Is there a way that vmbix can show the data on the vm's (disk, network etc) as well as graphs? Of course. Did you test vmbix with zabbix_get as stated in the README ? You can query VmBix like a Zabbix agent using the zabbix_get tool :

# zabbix_get -s 127.x.y.z -p 12050 -k about[*]
VMware vCenter Server 5.1.0 build-1364037
# zabbix_get -s 127.x.y.z -p 12050 -k esx.status[esx01.domain.local]
1
# zabbix_get -s 127.x.y.z -p 12050 -k vm.guest.os[MYVM01]
CentOS 4/5/6 (64 bits)
# zabbix_get -s 127.x.y.z -p 12050 -k esx.discovery[*]
{"data":[{"{#ESXHOST}":"esx01.domain.local"},{"{#ESXHOST}":"esx02.domain.local"}]}
# zabbix_get -s 127.x.y.z -p 12050 -k vm.counter[MYVM01,virtualDisk.totalReadLatency.average,scsi0:1,300]
2

If I use the module (I don't at the moment), will I need to install Zabbix agent on each vm in order to get the data? No, as stated in the README "The vmbix.so loadable module must be installed on your server/proxy.". So you don't need to install an agent on each VM.

Problem is that with ESXI 5.5 and above and VCenter/VCSA 6 - everything goes by UUID, so for example:

zabbix_get -s 127.x.y.z -p 12050 -k esx.status[esx01.domain.local] will give you: 4 (not 1) abbix_get -s 127.x.y.z -p 12050 -k vm.guest.os[MYVM01] Will give you some error (i'm not near the machine right now) as it expects a UUID.

dav3860 commented 8 years ago

No, VmBix translates the name or the UUID to the corresponding object. Set useuuid=true in the configuration. Then restart vmbixd and issue the following commands :

zabbix_get -s 127.0.0.1 -p 12050 -k esx.discovery[*]
zabbix_get -s 127.0.0.1 -p 12050 -k vm.discovery[*]

Please post the results.

That's with UUID as true, but again, zabbix complains that the host 'esxi1.hetztest.net' not found (although it is) and it's showing it not-connected/not-found with a "problem" flag (as shown on my first comment)

dav3860 commented 8 years ago

If you set useuuid=true, you must reference all the objects by their UUID in the queries. So these queries should work :

# zabbix_get -s 192.168.0.126 -p 12050 -k "esx.status[03000200-0400-0500-0006-000700080009]"
# zabbix_get -s 192.168.0.126 -p 12050 -k "vm.guest.os[42361bf2-a7ec-18d7-9f6b-4288d91cb2eb]"

Does it work ?

The templates here are provided as an example. If you use the UUID to reference the machines, the ESX hosts and the VM hosts created in the host prototype rules must have the name set to {#UUID} and the visible name set to {#VIRTUALMACHINE} or {#ESXHOST}. I'll update the documentation if it's not clear.

hetzbh commented 8 years ago

Yes, this does work. BTW, since ESXI 5.5 and up (and vCenter 5.x and up) running by default with UUID as default, why not changing the default to UUID with the templates?

2 more things:

dav3860 commented 8 years ago

I started to update the documentation and the Zabbix templates. Please use these ones if you have Zabbix 3.0. You'll have to install the loadable module before. The necessary value mappings should be created when you import the templates. If not, you will find them in the value mappings directory. The python script is necessary if you don't want to use LLD host prototypes to create the hosts, and programmatically create regular hosts instead in Zabbix.

hetzbh commented 8 years ago

I went back to Zabbix 2.4 (tons of external templates from the net don't work on Zabbix 3). Do You plan to release for 2.4 as well?

And thanks a lot for the kind help ;)

dav3860 commented 8 years ago

Well, I think that if you change the version to 2.4 in the template XML files, if will work. You will just have to create the value mappings manually before importing the templates. I have started to upgrade to Zabbix 3.0, so I don't have a working 2.4 setup with VmBix anymore.

hetzbh commented 8 years ago

I've installed the module and templates (and "fixed" them so they would look as 2.0) and I'm testing it on out VCSA 6. One problem on the logs keeps appearing though, for example:

  1360:20160627:153244.494 item "564d809d-2657-51d7-708c-d5435cb3a831:vm.cpu.ready.pct[{HOST.HOST}]" became supported

  1360:20160627:153244.494 item "564d2fd5-014d-6e88-156c-d8fa928b5298:vm.cpu.ready.pct[{HOST.HOST}]" became not supported: Cannot evaluate function "last()".
dav3860 commented 8 years ago

Hi, This is normal.These are calculated functions relying on other items, so they will be evaluated after a moment. Wait for a couple of hours and check if these items now have values.
