We are actively developing it and you should always update to the latest version. + +The update procedure depends on how you installed it: + +## You downloaded it from github using git + +### Manual update + +The installer `netdata-installer.sh` generates a `netdata-updater.sh` script in the directory you downloaded netdata. +You can use this script to update your netdata installation with the same options you used to install it in the first place. +Just run it and it will download and install the latest version of netdata. The same script can be put in a cronjob to update your netdata at regular intervals. + +```sh +# go to the git downloaded directory +cd /path/to/git/downloaded/netdata + +# run the updater +./netdata-updater.sh +``` + +_Netdata will be restarted with the new version._ + +If you don't have this script (e.g. you deleted the directory where you downloaded netdata), just follow the **[[Installation]]** instructions again. The installer preserves your configuration. You can also update netdata to the latest version by hand, using this: + +```sh +# go to the git downloaded directory +cd /path/to/git/downloaded/netdata + +# download the latest version +git pull + +# rebuild it, install it, run it +./netdata-installer.sh +``` + +_Netdata will be restarted with the new version._ + +Keep in mind, netdata may now have new features, or certain old features may now behave differently. So pay some attention to it after updating. + +### Auto-update + +_Please, consider the risks of running an auto-update. Something can always go wrong. Keep an eye on your installation, and run a manual update if something ever fails._ + +You can call `netdata-updater.sh` from a cron-job. A successful update will not trigger an email from cron. + +```sh +# Edit your cron-jobs +crontab -e + +# add a cron-job at the bottom. This one will update netdata every day at 6:00AM: +# update netdata +0 6 * * * /path/to/git/downloaded/netdata/netdata-updater.sh +``` + +## You downloaded a binary package + +If you installed it from a binary package, the best way is to **obtain a newer copy** from the source you got it in the first place. + +If a newer version of netdata is not available from the source you got it, we suggest to uninstall the version you have and follow the **[[Installation]]** instructions for installing a fresh version of netdata. + + + + + + + |
