Issues with Zabbix LLD Item Key Format for SMART Monitoring

[doctorbal82]

Hello,

I am looking into monitoring XenServer disk health. I am using concepts from zbx-smartctl Zabbix Share.

I modified the script (attached below in txt output) and have the following JSON output on the "uHDD.discovery" discovery rule:

{
        "data":[


                {
                        "{#DISKNAME}":"bus/0",
                        "{#ARGS}":"-d megaraid,0",
                        "{#SMART_ENABLED}":"1"
                }
        ]
}

My userparameter_smart.conf file has the following:

UserParameter=uHDD.discovery,sudo /etc/zabbix/smartctl-disks-discovery.pl
UserParameter=uHDD.health[*],sudo smartctl -H /dev/$1 $2

and following Item prototype from the discovery list:

Name: {#DISKNAME}: Test result
Type: Zabbix agent
Key: uHDD.health["{#DISKNAME}","{#ARGS}"]
Type of information: Character
Show value: As is

I want to achieve the following:

sudo smartctl -H /dev/bus/0 -d megaraid,0

When I try to test this with zabbix_get I get the following error response which results in no output.

zabbix_get -s 127.0.0.1 -k uHDD.health["bus/0","-d megaraid,6"]

/dev/bus/0 -d megaraid: Unable to detect device type
Please specify device type with the -d option.

Use smartctl -h to get a usage summary

What is missing in the syntax to get the output to display correctly?

I resolved this with the following below.

Note that I am running zabbix-agent version 3.4.15 on a XenServer 7.2 host which is based off of CentOS 7 OS Distro and this is installed on Dom0 ("Domain 0").

install...

 rpm -ivh https://repo.zabbix.com/zabbix/3.4/rhel/7/x86_64/zabbix-release-3.4-2.el7.noarch.rpm
  yum install zabbix-agent zabbix_get
  firewall-cmd --zone=public --add-port=10050/tcp --permanent
  service iptables restart
  yum install smartmontools sg3_utils

Testing this; note the single quotes!

sudo -u zabbix zabbix_get -s 127.0.0.1 -k 'uHDD.health["bus/0","-d megaraid,7"]'
