System Metrics for Monitoring

Why use the System Telegraf plugin?

The System plugin collects general usage data that can help benchmark or identify problem areas in your system or applications.

Monitoring system performance is important in identifying the root cause of performance degradation. Combining system metrics with Telegraf plugins such as Disk and Disk I/O, Mem Telegraf Input, PF, and SNMP to provide a broader view into overall system performance, including memory, storage, network connectivity, etc. This important data can be used to resolve performance issues, proactively monitor hardware, and get detailed real-time reports on utilization, traffic and, various interface parameters.

How to monitor System using the Telegraf plugin

Determine which metrics you want to collect and from which CPUs. Get the number of available CPUs from the /proc/cpuinfo file. Point the configured plugin at InfluxDB to start collecting metrics.

Some of the important System metrics that you should proactively monitor include:

• load1
• load15
• load5
• n_users
