도커 커널 설정값 변경

  1. 도커 컨테이너 설정 값 확인 -> docker inspect b24bb0e977d3 "Privileged": false, 값 확인

  2. 해당 컨테이너 중지 + 도커 서비스 중지

  3. 설정 파일 수정 /var/lib/docker/containers/b24bb0e977d3844163fe97ae64290c6b350ec3e0ad51bbea614b51587a937c8f/hostconfig.json -> "Privileged":true 로 변경

  4. 도커 실행 docker exec -u 0 -it b24bb0e977d3 /bin/bash

  5. 도커 컨테이너 안 설정 값 변경

echo 1 >/sys/kernel/mm/ksm/run echo 0 > /proc/sys/kernel/randomize_va_space echo 1000 >/sys/kernel/mm/ksm/sleep_millisecs

[일련의 과정 다시 정리] docker container stop하기 docker service stop하기(service docker stop) docker config file 수정하기(config.v2.json, hostconfig.json) start docker service (service docker start) docker container start하기

--- Telemetry configuration --- You can opt out from anonymous statistics via the --disable-telemetry option, or by creating an empty file /opt/netdata/etc/netdata/.opt-out-from-anonymous-statistics

--- Install netdata at system init --- We are running within a docker container, will not be installing netdata service

--- Restarting netdata instance ---

Stopping all netdata threads [/root/netdata]# stop_all_netdata

--- Check KSM (kernel memory deduper) ---

Memory de-duplication instructions

You have kernel memory de-duper (called Kernel Same-page Merging, or KSM) available, but it is not currently enabled.

To enable it run:

echo 1 >/sys/kernel/mm/ksm/run
echo 1000 >/sys/kernel/mm/ksm/sleep_millisecs

If you enable it, you will save 40-60% of netdata memory.

--- Check version.txt --- --- Check apps.plugin --- --- Copy uninstaller --- --- Basic netdata instructions ---

netdata by default listens on all IPs on port 19999, so you can access it with:

http://this.machine.ip:19999/

To stop netdata run:

killall netdata

To start netdata run:

/opt/netdata/usr/sbin/netdata

Uninstall script copied to: /opt/netdata/usr/libexec/netdata/netdata-uninstaller.sh

--- Install netdata updater tool --- Update script is located at /opt/netdata/usr/libexec/netdata/netdata-updater.sh

Cannot figure out the cron directory to handle netdata-updater.sh activation/deactivation --- Wrap up environment set up --- Preparing .environment file Setting netdata.tarball.checksum to 'new_installation'

--- We are done! ---

센서 탭 off 상황 확인

cat /var/log/netdata/error.log | grep sensors

netdata start

/opt/netdata/usr/sbin/netdata

set sensors=force to /etc/netdata/charts.d.conf

cat /var/log/netdata/error.log | grep python

확인 순서

sensors find /sys -maxdepth 11 -name *_input -o -name temp

export NETDATA_HOST_PREFIX="/host" /usr/libexec/netdata/plugins.d/python.d.plugin debug trace 1 cpufreq

sensors 탭 안보일 경우

charts.d.conf 에서 sensors=force 항목 주석 제거 후

.../netdata/netdata-installer.sh 재실행
