最近grafana上有些报警没有报出来，而且旧的版本bug也比较多，今天看了下最新版本是7.0。升级之后发现图片渲染出了问题：

翻了下官网的文档：

Starting from Grafana v7.0.0, all PhantomJS support has been removed. Please use the Grafana Image Renderer plugin or remote rendering service.

Breaking changes

  • Removed PhantomJS: PhantomJS was deprecated in Grafana v6.4 and starting from Grafana v7.0.0, all PhantomJS support has been removed. This means that Grafana no longer ships with a built-in image renderer, and we advise you to install the Grafana Image Renderer plugin.

grafana已经废弃了phantomJS的支持，推荐使用Grafana Image Renderer plugin， 安装之后图片仍然没有渲染出来。打开渲染的debug日志：

# Either "debug", "info", "warn", "error", "critical", default is "info"
;level = info

# optional settings to set different levels for specific loggers. Ex filters = sqlstore:debug
