JSONPath preprocessing null values

[markfree]

Zabbix 6.2 and 7.4

Lets consider the JSON set below.

"IDENTIFIER": "123456789",
"SEQUENCE_NO": "6",
"EXTERNAL_SYSTEM": "SYSTEM",
"PROCESS_DATE": "2026-04-14 00:00:00",

Can someone guide me on how I can use Javascript preprocessing with vmware.vm.discovery returned JSON?

Also is there some schema definition of the returned json to use here?

Thanks
John...

Hi,
I had a unique requirement where I had to do deduplication based on substring of a whole message but after dedup want to preserver the full message.
For example if the alarm message formed is like "VARBIND1=<varbind-value1> VARBIND2=<varbind-value2> VARBIND3=<varbind-value3>"...

I have some devices that discover many items each.
I'm refactoring their template so that the devices can benefit from the SNMP Walk feature.

The parent "Walk" item finds many SNMP OIDs and its dependent items use preprocessing to identify the item values.

I'm monitoring an HTTP endpoint that returns a text list, and use a Javascript preprocessing step to count the number of lines.

Sometimes the returned value is empty, so Zabbix makes the item unsupported.


I could use a "Check for not supported value" preprocessing...

Whenever I get a timestamp value like "yyyymmddhhMMss", if necessary, I convert it to "unixtime" with a JavaScript preprocessing step.

This script is usually sufficient:

// checks if the input value is null
if (isNaN(Date.parse(value))) { return 0; }

I have noticed that some item values displayed by the "Item Value" widget are not displayed in the dashboard. Instead, a "no data" message is displayed.


The item has an interval of 1 day and a "discard unchanged" preprocessing step with a heartbeat...

Hello there!

I have been using and configuring Zabbix for several months now. I was customizing a template when I came across the Discard Unchanged with Heartbeat preprocessing rule. I looked it up in the documentation and it sounds like it would be highly useful in reducing the storage...

Hello,

I am creating a Zabbix template to monitor a commercial software package.
I am using a lot of Low-Level Discovery (LLD) and it works.
However, some of the preprocessing rules seem redundant, so I am wondering if I am perhaps not using the most effective/efficient way...

Hi,

I have this command output format in:

key1 : value1
key2 : value2
key3 : value3

I'd like to get the value from the specific key.

I tried to convert this using CSV to JSON with colon as delimiter, but I got the output

I'm trying to parse through dpkg versions with the "system.sw.packages.get" key.
Dpkg prepends and appends various data that I want to trim off so it can be consistent accross different package managers.
For example I would like to get rid of the ":1" and the "+deb11u1"...

Title might not be entirely clear but the problem is quite specific. I want to create a discovery rule with the output shown here:
