Nodes view not available when node cpu not supported

[barcus]

Hello,

I got at internal error when i try to display nodes. I seems to be linked to my new nodes, which reports -1 as a CPU percent value in nodes API

Error logs: NOTICE: PHP message: PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 20480 bytes) in /var/www/html/vendor/symfony/http-client/Response/CommonResponseTrait.php on line 92

Thanks a lot !

Looks like i need to upgrade to Elastic 7.16 to be compliant with my new Debian 11 nodes ! Unfortunately it's the same with some others pages, like audit, pretty sure it's linked to those new nodes, it worked before.

Could be nice to be able to display at least nodes until i upgrade :)

Hi

Not sure it's related to data. I made a test to overwrite the values ['stats']['process']['cpu']['percent'] and ['stats']['os']['cpu']['percent'], no issue

I think for this node you have more data than usual when you get responses from Elasticsearch and PHP need more memory to handle all

CommonResponseTrait.php on line 92 => json_decode used for the response from Elasticsearch

Can you upgrade the value "memory_limit" in your php.ini? 200M at least
