I want to track my custom processes through Zabbix (v2.4.8). I am generating the following json object and sending it through UserParameter=service.value[*],/usr/lib/zabbix/externalscripts/custom1.bash:
{
"data":[
{
"{#NAME}":"ntp",
"{#VALUE}":"1"
},
{
"{#NAME}":"mysql",
"{#VALUE}":"1"
},
{
"{#NAME}":"prometheus",
"{#VALUE}":"0"
},
{
"{#NAME}":"apache2",
"{#VALUE}":"0"
}
]
}
Also, creating an item prototype and graph prototype inside a new template with a new discovery rule, having the following information:
Discovery rule name: Service Graph
Type: Zabbix Agent
key: service.value
Item Prototype name: Service {#NAME} Graph
Type: Zabbix Agent
key: service.value[{#NAME},{#VALUE}]
Type of info: Numeric(Unsigned) & Decimal
When I apply these settings, the items keep giving the following error:
Not supported: Received value [{ "data":[ { "{#NAME}":"ntp", "{#VALUE}":"1" }, { "{#NAME}":"mysql", "{#VALUE}":"1" }, { "{#NAME}":"prometheus", "{#VALUE}":"0" }, { "{#NAME}":"apache2", "{#VALUE}":"0" } ]}] is not suitable for value type [Numeric (unsigned)] and data type [Decimal]
I have to create a graph prototype with these settings, so I cannot mention type as "Text" for obvious reasons.
Another question: The graphs thus generated are not clickable at all like the other existing graphs.
Please let me know where I am going wrong.
If your service.value key generates JSON, that should be used with the LLD rule only. You should not send any values in it. The key to be used in the prototypes should be like any normal key they only returns values it was asked for, do not use the LLD-generating key there.
Your current JSON looks like you might be able to use the built-in items for process monitoring, but that is hard to be sure about without additional detail.
Also note that [*] in the UserParameter definition is not needed if you do not pass parameters to this key.
