The poller issue CentOS 8

Hi all,

I think I got the performance issue on the poller and rrdtool on CentOS 8.
I tried to follow this [guide]((https://www.techsupportpk.com/2019/12/how-to-install-and-configure-librenms-centos-rhel8.html) to install LibreNMS on CentOS 8, then I use snmp-scan.py to discover all of network devices in my environments.

I notice the information was not display on the page completely, and I also execute “./validate.php”
to check is there have any error message.

I also check mail to see the log for cron job, but I can not install this “python-mysqldb” module on CentOS 8.

Does anyone faced same issues before?

I have same centos 8 installation, from the same guide and the same issue with poller wrapper.
You can use python3 librenms dispatcher service: https://docs.librenms.org/Extensions/Dispatcher-Service/
or try to install python2 mysqldb module.
For example: https://stackoverflow.com/questions/25865270/how-to-install-python-mysqldb-module-using-pip

Yes, I have same problem. I have reinstalled this with CentOS 7. With CentOS 7, it is working fine.

It seems working after I use dispatcher service! Most of graph can be created!
But there still have some graph have some issue, maybe I need to rejoin these devices…
