Problem/Question
While installing Netdata 2.2.6, I am encountering repeated errors related to apps.plugin failing to process /proc/<pid>/io and /proc/<pid>/fd for multiple processes, including inotifywait and sleep.
Steps to Reproduce:
- Install Netdata 2.2.6 using (netdata-installer.sh)
- Start Netdata (
systemctl start netdata) - Observe the logs using
systemctl status netdata.service
Environment/Browser/Agent’s version etc
/opt/usr/sbin/netdata -v
netdata v2.2.6
/opt/scorer/usr/sbin/netdata -W buildinfo
