Datastore IOPS monitoring

[ghost]

Hello,

I have Zabbix 3.0.3 with VmBix 2.2 installed and configured to monitor vCenter 6 with two ESX hosts. There are 3 datastores connected over FC SAN switch.

Hosts and datastores are successfully discovered by using the VmBix vCenter Loadable Module template. VmBix is configured to use VMWare UUID to identify objects.

Is there a way to monitor latest IOPS value of datastore? I tried to use the \ datastore.datastoreReadIops.latest and datastore.datastoreWriteIops.latest ESX counters, but getting error Check access restrictions in Zabbix agent configuration

[root@zabbix ~]# zabbix_get -s 127.0.0.1 -p 12050 -k "esx.counter[50673472-be243ac8-98e8-2c768a52d4fd,datastore.datastoreReadIops.latest]"
zabbix_get [93941]: Check access restrictions in Zabbix agent configuration

50673472-be243ac8-98e8-2c768a52d4fd is UUID of one datastore.

I got same error when used UUID of ESX host:

[root@zabbix ~]# zabbix_get -s 127.0.0.1 -p 12050 -k "esx.counter[32333536-3030-5a43-3232-333430325350,datastore.datastoreReadIops.latest]"
zabbix_get [92429]: Check access restrictions in Zabbix agent configuration

32333536-3030-5a43-3232-333430325350 is UUID of one ESX host.

Please help, what I have missed?

The counter has multiple instances. List the instances of this performance counter using :

zabbix_get -s 127.0.0.1 -p 12050 -k "esx.counter.discovery[myesx01,datastore.datastoreReadIops.latest]
{
  "data": [
    {
      "{#METRICINSTANCE}": "54abdb23-2d2356f6-f002-001a4bef4838",
      "{#METRICNAME}": "DS01"
    },
    {
      "{#METRICINSTANCE}": "558ac8df-a17d83a4-4e64-a0b3cce0dcda",
      "{#METRICNAME}": "DS02"
    }
  ]
}

Then, you can get the counter value for each instance like this :

zabbix_get -s 127.0.0.1 -p 12050 -k "esx.counter[myesx01,datastore.datastoreReadIops.latest,558ac8df-a17d83a4-4e64-a0b3cce0dcda]"
0

So you need to use low-level discovery to discover the instances in Zabbix (see the CPU discovery rule in the provided templates).

Thank you very much, that worked for me.

I successfully created item for particular datastore host (placed in Datastores host group) for example simple check key for manually created item for Datastore 3 was vmbix[esx.counter,32333536-3030-5a43-3232-333430325350,datastore.datastoreReadIops.latest,56f7c5b3-9d9d4e5d-7ac4-2c768a536e5c] Received values are going from 2 to 47 (Numeric unsigned, decimal). What this values are representing? Number of Iops?

One more question, how to create item prototype for the datastore.datastoreReadIops.latest counter in VmBix vCenter Loadable Module template? I tried to create item prototype named Datastore {#DATASTORE} Read IOPS with simple check key vmbix[esx.counter,{32333536-3030-5a43-3232-333430325350,datastore.datastoreReadIops.latest,{#METRICINSTANCE}]

didnt got any data, I dont know what I made wrong.

I also tried counter disk.totalReadLatency.average. Discovery command given me following output:

zabbix_get -s 127.0.0.1 -p 12050 -k "esx.counter.discovery[32333536-3030-5a43-3232-333430325350,disk.totalReadLatency.average]"

{
    "data":[
    {"{#METRICINSTANCE}":"naa.600c0ff00014a8563944675001000000"},
    {"{#METRICINSTANCE}":"naa.600508b1001ca821146614f1a958cdab"},
    {"{#METRICINSTANCE}":"naa.600c0ff00014f1b9f4def75601000000"},
    {"{#METRICINSTANCE}":"naa.600c0ff00014a856fe21675001000000"}]
}

What values naa.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx are meaning? Are these values some kind of UUIDs for physical disks?

I would highly appreciate any help about this. Thank you in advance.

Check here for information about the received values : https://www.vmware.com/support/developer/converter-sdk/conv61_apireference/datastore_counters.html

For the item prototypes, create :

• a LLD discovery rule like this : vmbix[esx.counter.discovery,{HOST.HOST},datastore.datastoreReadIops.latest]
• an item prototype like this : vmbix[esx.counter,{HOST.HOST},datastore.datastoreReadIops.latest,{#METRICINSTANCE}] with a name Datastore {#METRICNAME} Read IOPS
• another item prototype for the writes : vmbix[esx.counter,{HOST.HOST},datastore.datastoreWriteIops.latest,{#METRICINSTANCE}]

For the naa.xxxx values, yes it's a VMWare ID for the disks (you can see them in the VMWare Client).

dav3860, Thank you for valuable help you provided to me. Your instructions precisely conducted me to solve my doubts about VmBix counters.

Also, big THANK YOU for the outstanding piece of software.

Cheers, Jovan
