@@ -25,6 +25,8 @@ There are several extras which are required only for some scripts:
- script designed to execute multiple monitoring probes
- output is compatible with CheckMK
- it is required to put configuration file to `/etc/run_probes_cfg.yaml`
+- default timeout in seconds for all checks is set by `default_timeout` in the config, and each check can optionally have its own `timeout` setting overriding the default one.
