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.
