![]() Click “Save & Test” and Grafana will check the connection and save the data source. You can also specify that this data source will be used by default. If the standard plugins are not enough you can download the one you need.Ĭhoose “Graphite” and configure data source settings: By default, Grafana supports Graphite, Open TSDB, and several other aggregators. Go to “Configuration” and choose “Data Sources”. First of all, we need to set up a data source because Grafana concentrates on the visualization part of the metric analysis. Now let's figure out how to build a Grafana dashboard to monitor server load. How to monitor server load with the Grafana dashboard Grafana is a powerful visualization tool that allows you to connect to Graphite and build customized interactive dashboards, set alerts for specific events, and much more. Graphite is a monitoring tool that efficiently stores time-related data (through the Whisper database), provides an interface for basic visualization of the stored data, and gives mathematical functions to sum/group/scale stored data in real time. So let’s summarize what Graphite and Grafana are. Note that with the help of Graphite and Grafana, you can also monitor cloud servers that provide all of the providers: AWS, GCP, Azure, Digital Ocean, etc. If you need more information about Collectd installation and its plugins, please read our blog post-Collectd plugins. Also, there are plugins to monitor different software, plugins that can aggregate and push metrics to a database, and many others.Ĭollectd sends metrics to Graphite via the “Write Graphite” plugin on port number 2003. The most common plugins can be the following: monitor CPU, memory, network, and swap usage. There are many plugins for a wide variety of purposes. It tracks and sends metrics to Graphite via its plugins. Collectd must be installed on each PC, whose indicators you need to monitor. It’s a small application that was designed to collect metrics. For this reason, we will use Collectd as the metric collector. In this article, we will monitor server load with Ubuntu 18.04 LTS operating system. The web application pulls data from storage and builds graphs. Carbon gradually puts them in storage (DB). The collector partially aggregates them and sends them to Carbon with a given frequency. The server generates metrics and sends them to the collector. ![]() In general, the metrics collection system can be described with the following diagram: Even Graphite, in itself, consists of at least three subsystems - a metric collection Daemon (carbon), a database with metrics (W hisper, etc.), and a web application for visualization.Īt the same time, the standard Graphite web application can be replaced with the more advanced Grafana. It may include a different number of components, each of which somehow interacts with the others, has its configuration file, and is a unique way to start. The metrics collection system may have different compositions. Graphite focuses on data collection, storage, serialization, and transmission, while Grafana excels in data visualization and analysis.Grafana allows users to create customized interactive dashboards for monitoring various server metrics such as CPU usage, system load, memory usage, disk I/O, and used disk space.Collectd is a useful metric collector that sends data to Graphite for analysis and visualization.Graphite and Grafana complement each other well in the metrics collection and visualization process.Server outages can lead to loss of customers and reputation, making it crucial to monitor server load in a timely manner.If you would like to learn more about it please book a demo with us, or sign up for the free trial today. You can use our product with minimal configuration to gain in-depth insight into your environment. This is very convenient for solving the tasks described above. MetricFire specializes in monitoring systems and uses both Graphite and Grafana. These two programs complement each other well and make server monitoring simple and efficient. Graphite copes well with these task s, and Grafana makes visualization beautiful and understandable. For example, if your server load metrics are showing issues, you will be able to correlate it with page load speed or another KPI of your app. There is also a possibility to correlate app statistics with server load metrics. Servers generate a large number of metrics and it is essential to not only track their values but also to observe their changes over time. MetricFire's Hosted Grafana and Graphite will help you monitor server load in a timely and efficient manner. ![]() ![]() Since server outages can lead to a loss of customers, reputation, and other troubles and it is important to get information on the status of the server on time.
