Unparalleled insights, in real-time, of everything happening on your systems and applications, with stunning, interactive web dashboards and powerful performance and health alarms Vérification du script[ "0ae8dd3c4c9b976c4342c9fc09d9afae" = "$(curl -Ss https://my-netdata.io/kickstart.sh | md5sum | cut -d ' ' -f 1)" ] && echo "OK, VALID" || echo "FAILED, INVALID" OK, VALID InstallationSur chaque machine, il faut installer ce script: ssh root@xxxxx mkdir netdata cd netdata script -t$(date +%Y-%m-%d)-install.time $(date +%Y-%m-%d)-install.log bash <(curl -Ss https://my-netdata.io/kickstart.sh) --stable-channel --dont-wait exit Pour Les anciennes version de script -t $(date +%Y-%m-%d)-install.log 2> $(date +%Y-%m-%d)-install.time Les droits Ce script, multi-os installe ou compile les sources dans /usr/src/netdata par défaut. Des commandes de post-installation permettent de réduire la consommation mémoire: Kernel Same-page MergingSi on voit: 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. On lance cat >> /etc/rc.local <<EOT # netdata - KSM echo 1 >/sys/kernel/mm/ksm/run echo 1000 >/sys/kernel/mm/ksm/sleep_millisecs EOT et on vérifie: cat /etc/rc.local Installation binairebash <(curl -Ss https://my-netdata.io/kickstart-static64.sh) Dans ce cas, netdata est installé dans /opt/netdata note installation - nov 2019
