Linux logs
StackState Self-hosted v5.0.x
This page describes StackState version 5.0.
Overview
In a Linux setup, StackState keeps all log files in the var/log subdirectory of the StackState installation directory. By default this is /opt/stackstate/var/log. In case of a two-node installation, logs are kept in the var/log directory on each node. Note that the logs are node-specific - the StackState node keeps StackState related logs and the StackGraph node keeps logs related to StackGraph.
var/log details
var/log detailsInside var/log, there is a subdirectory for each type of logs kept by StackState. By default, each subdirectory has a size cap of 2 GB; when exceeded, the oldest files are deleted. Example of var/log contents:

Log files
StackState keeps logs in files that have a maximum size of 50 MB. When a log file exceeds 50 MB size cap, it is divided into ordered parts, as in the below example:
./sync:
total 1043088

-rw-r--r--. 1 stackstate stackstate 52430381 Dec 18 10:26 sync.Agent.2019-12-18.3.logDefault log pattern
StackState builds log files using the following default log pattern: "%date [%thread] %-5level %logger{60} - %msg%n"
