collectd-top's Introduction

Welcome to Michel's GitHub Page! 👋

My name is Michel Gokan Khan & I'm a computer science researcher. I'm currently conducting research as a PostDoc at KTH Royal Institute of Technology and AstraZeneca in ML-Driven Optimization of Production in Industry 5.0. I have a PhD in computer science from KAU Sweden 🇸🇪. My focus was optimizing service function chains in the context of cloud native computing with use cases in 5G networks and NFV through deep learning.

segfault after executing 'service collectd stop'

Hi,

I am running Collectd-5.1.0 on CentOS 5.8 , perl v5.8.2.

commented line 'use 5.018002;' since I wanted to use the default version. Compiled and Installed the module successfully. No errors

Receiving 'segfault' in syslog after executing 'service collectd stop'. Collectd starts fine and loads the plugin, but stopping produces the error

collectd[3070]: segfault at 0000000000000000 rip 0000003faf078900 rsp 00007fff53ef02d8 error 4

Adding process name?

Is there any way to add the active running process name to this?

Thanks,
