Check_load against localhost is blank #16

Open BuckGup opened 4 years ago

BuckGup commented 4 years ago

When I run the check_load against the localhost the webpage is blank. I can still get metrics from Prometheus but that don't correlate to NRPE and look like basic default metrics like up and process_max_fds Any ideas to why? Thanks

If it helps I am also on CentOS 8 and using the same version of NRPE

Hello,

For information, I solved problem. I disabled SSL. On CentOS 8, you don't have /etc/default/nrpe for boot option, so, directly in systemd nrpe file, you need add --no-ssl option.
