Hi,
Did you try the last version (in testing), which is the 1.29.2 ?

Can you tell me if it's a duplicate of https://bugzilla.redhat.com/show_bug.cgi?id=1918443 ? or if problem is completely different.

BTW 1.29.3 is out, I prepare it ASAP

Cheers,

Comment 2 Alan Brown 2021-03-01 22:15:46 UTC

It's a different error

I wasn't using -testing, will try that now

Comment 3 Alan Brown 2021-03-01 22:21:00 UTC

Ok, using 1.29.3, the error is stil there

nothing obvious is showing in /var/log/netdata


Using jsonlint.com's validator on the old version: 

Error: Parse error on line 17676:
...s": {				"fdperc": nan			},			"green"
----------------------^
Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[', got 'undefined'

Comment 4 Didier Fabert (tartare) 2021-03-02 08:02:23 UTC

Do you have one or more modified config files by hand (or with edit-config script) or do you still have default files ?

In case of no, this bug must be escalate to upstream and if you don't do it yet, I can open it for you.

Pretty sure that json file will be asked for this, so can you prepare a obfuscate version ?
