How to change the log level of "hawk-apiserver" service

This document (000020986) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Linux Enterprise High Availability Extension 15

Situation

To troubleshoot Hawk2 issue, it may be required to change the log level of the "hawk-apiserver" service.

Resolution

The log level for the "hawk-apiserver" service can be changed by setting the "loglevel" parameter in the file "/etc/hawk/server.json".

The possible values for the "loglevel" parameter are as follows:
debug
info
warning
error
fatal
panic

By default the "loglevel" parameter is not set in "/etc/hawk/server.json", but the default value is internally set to "info".

For example, to set the log level of the "hawk-apiserver" service to "debug" level, add the "loglevel" parameter to "/etc/hawk/server.json":
{
"loglevel": "debug",
"route": [
{
"handler": "monitor",
"path": "/monitor"
},
......
}

Restart the hawk service.
For example:
systemctl restart hawk.service

The "hawk-apiserver" debug messages will now be printed in the system message log.
For example:
... systemd[1]: Starting HA Web Konsole...
... systemd[1]: Started HA Web Konsole.
... hawk-apiserver[18102]: level=info msg="Reading /etc/hawk/server.json..."
... hawk-apiserver[18102]: level=info msg="Listening to https://0.0.0.0:7630\n"
... hawk-apiserver[18102]: level=debug msg="[proxy] / -> unix:///usr/share/hawk/tmp/hawk.sock"
... hawk-apiserver[18102]: level=debug msg="[proxy] /login -> unix:///usr/share/hawk/tmp/hawk.sock"
... hawk-apiserver[18102]: level=debug msg="[file] /usr/share/hawk/public/assets/vendor-420e822e02c390e16b4686904ca61330ef4e6a5b1004951429196a1f3a245f62.css"
... hawk-apiserver[18102]: level=debug msg="[file] /usr/share/hawk/public/assets/authentication-12e2206a5fce0a847386ab20b1906c2d9311f4a3e84f1ed7853c59429a8c5e39.css"
