2020.05.06 17:00:32.728649 [ 1 ] {} <Information> Application: It looks like the process has no CAP_NET_ADMIN capability, 'taskstats' performance statistics will be disabled. It could happen due to incorrect ClickHouse package installation. You could resolve the problem manually with 'sudo setcap cap_net_admin=+ep /usr/bin/clickhouse'. Note that it will not work on 'nosuid' mounted filesystems. It also doesn't work if you run clickhouse-server inside network namespace as it happens in some containers.

It could happen due to incorrect ClickHouse package installation. You could resolve the problem manually with 'sudo setcap cap_sys_nice=+ep /usr/bin/clickhouse'.
