How to Remove empty record in Lastest data / History ?

[darklord1990]

Hello guys. Could you please help me on this case ?

I added an userparameter to call my local script with key "node.log". This script will check log file and show its content. If there is no new file, Script will not show anything.
Then, I created item with that key to show content the log file with Update interval = 30s.

As my script will show the new file only, so if there is no new log file, there is empty record in Lastest data / History.



My question is : Can I remove these empty records ? Or Can we skip check if there is no new log file ?

I am using Zabbix 3.4 with Centos 7.4

As far as I understand it, those entries are generated by the checks you asked Zabbix to do, therefore, the only way to remove them is to stop the checking.

Thanks myRCzabbix for your reply.

In my opinion, The item will check if there is new log file, and otherwise, it will skip the check
Are there any way to do that ?

[myRCzabbix]

That doesn't make any sense ... how can Zabbix skip a check when there is no new log file if the only way to determine if there is a new log file is to check for it? That's a catch-22.

Perhaps you want to do something different than what you are describing.

I want to show log data of new file only. My script already did that. But I dont know how to show up in Zabbix.

Could you please give me some advice ?

You really could just ignore it (the blank entries, I mean, in Latest Data). They don't affect you in any way.

The only other way to do it (and someone else might correct me if I'm wrong), is that if you really want to keep your Latest Data list clean, you could set up the check as a discovery rule. But I think given that it's more complicated and doesn't give you anything in return except a cosmetic improvement, I'd advise against it.

OK Thanks . Let me try with discovery rule.
