Telegraf is maintained by InfluxData, the people behind InfluxDB. It can then send those metrics to a variety of datastores, e.g. system statistics, API calls, DB queries, and SNMP. Telegraf: Telegraf is “…a plugin-driven server agent for collecting and reporting metrics.” This can collect data from a wide variety of sources, e.g.It is designed for exactly this use-case, where metrics are collected over time. InfluxDB: InfluxDB is “…a data store for any use case involving large amounts of timestamped data.” This is where we’re going to store our network statistics.We’re going to use this as our main front end for visualizing our network statistics. It works with several different data sources such as Graphite, Elasticsearch, InfluxDB, and OpenTSDB. Grafana: Grafana is “The open platform for beautiful analytics and monitoring.” It makes it easy to create dashboards for displaying data from many sources, particularly time-series data.We can write our own scripts like shell scripts or python scripts to generate metrics. Telegraf can collect database metrics like MongoDB, MySQL, Redis, and others and send metrics to Grafana.ĭatabase monitoring is available through the Telegraf plugin. For example: we can get all the CPU metrics like usage_guest, usage_idle, usage_iowait etc. This is critical for our system monitoring. From these metrics, we can easily see what is going on for our Linux systems. Yes, these beautiful charts are generated by Grafana/InfluxDB/Telegraf. Most metrics are directly pulled from the OS /proc directory every 15 seconds, although it is possible to alter the collection interval. The telegraf agent collects basic system metrics including memory usage, CPU utilization, disk I/O statistics, and more. Monitor Basic OS metrics For Linux system Monitor Basic OS metrics For Linux system.We can monitor the following metrics with TIG system. Today we are going to learn Linux metrics we can monitor using this monitor bundle Telegraf/Influxdb/Grafana. Luckily we have open-source software to monitor these metrics now. Linux monitoring is not an easy task for Linux admins.
