Graphite 安装必要软件包： $ sudo apt-get install apache2 libapache2-mod-wsgi python-django \ python-twisted python-cairo python-pip python-django-tagging 用 pip 安装 whisper (简单的存放和操作数据的库), carbon (监控数据的 Twisted 守护进程) 和 graphite-web (Django webapp)： $ sudo pip install whisper $ sudo pip install carbon $ sudo pip install graphite-web 初始化配置，直接用 example 文件里的默认配置就可以： $ cd /opt/graphite/conf/ $ sudo cp carbon.conf.example carbon.conf $ sudo cp storage-schemas.conf.example storage-schemas.conf $ sudo cp graphite.wsgi.example graphite.wsgi 修改 apache 配置，增加一个 vhost 或者偷懒下载一个配置文件覆盖 default，覆盖后需要重新 reload 配置： $ wget

Spring-Boot actuator exposes many useful metrics at /metrics such as uptime, memory usage, GC count. Only a subset of these are sent to Graphite when using the Dropwizard Metrics integration. In specific, only the counters and gauges Is there any way to get these other metrics to be published to graphite? The documentation suggests that it should be possible: Users of the Dropwizard ‘Metrics’ library will find that Spring Boot metrics are automatically published to com.codahale.metrics.MetricRegistry System Metrics created by Spring boot are not reported automatically because MetricsRegistry

If I ask for this data: https://graphite.it.daliaresearch.com/render?from=-2hours&until=now&target=my.key&format=json I get, among other datapoints, this one: [ 2867588, 1398790800 ] If I ask for this data: https://graphite.it.daliaresearch.com/render?from=-10hours&until=now&target=my.key&format=json The datapoint looks like this: [ null, 1398790800 ] Why this datapoint is being nullified when I choose a wider time range? Update I'm seeing that for a chosen date range smaller than 7 hours the resolution of the datapoints are every 10 seconds and when the date range chosen is 7 hours or bigger

Overview 概述 What Graphite is and is not ? Graphite能做什么和不能做什么? Graphite does two things: Graphite 做两件事情： Store numberic time-series data 存储 numberic time-series 数据 Render graphs of this data on demand 使用这些数据按需求渲染图表 What Graphite does not do is collect data for you, Graphite 不能为你收集数据， however there are some tools out there that know how to send data to graphite. 然而这里有很多工具，使用它们发送数据给graphite. Even though if often requires a little code , sending data to Graphite is very simple. 虽然这需要一点代码， 但是发送数据给Graphithe非常简单。 About the project 关于这个项目 Graphite is an enterprise-scale monitoring tool that runs well

I have a scenario as follows. Nginx is being used as a reverse proxy to a apache server listening at port 8080. nginx is running at port 80. There is a wsgi application which is being run by the apache server. Now, I have added a proxy_pass to the nginx configuration such that whatever requests come to localhost/ (nginx port is the default port 80) they get redirected to localhost:8080. Here is an excerpt from the nginx conf file: server { listen 80; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $remote_addr; proxy_set_header Host $host; location <app_name> { proxy
