What is Syslog?

Supported by InfluxData

Syslog protocol standard defined

Syslog is a protocol standard that describes how log messages should be formatted and transmitted. Devices and applications can send data about status, events and diagnostics to a central server, a.k.a. Syslog server, where a listener process gathers the data sent over UDP or TCP.

Syslog network monitoring overview

Syslog monitoring involves sending Syslog messages to a central location for storage, filtering, analytics, visualization and alerting. The majority of network devices communicate Syslog messages, which include information about IP address, timestamp, and the actual log message, as well as built-in severity levels ranging from an emergency to debugging purposes, providing valuable insights for network monitoring and alerting.

Syslog network monitoring with Telegraf

InfluxDB supports Syslog network monitoring via the Telegraf Syslog Input Plugin, which allows Telegraf to ingest logs using the Syslog protocol. Telegraf converts the Syslog messages to line protocol to be written to InfluxDB, from which data can be queried in real-time for alerts using Kapacitor and visualized using Chronograf, Grafana, or other visualization tools.
