How to reduce husarnet-daemon logs?

[bnbhat]

Hi,

How to reduce the logs created by the daemon?

Daemon is logging thousands of lines and I would like to only have error or warning level logs from it.

Aug 10 00:47:39 AP-004 husarnet-daemon[908]: 2024-08-10_00:47:39 INFO     hello 2 from a*****b
Aug 10 00:47:39 AP-004 husarnet-daemon[908]: 2024-08-10_00:47:39 INFO     established secure connection to *****

Thank you!

Hi @bnbhat

You can do this using HUSARNET_LOG_VERBOSITY variable.

Here is what each value for this variable means:

    NONE, /* 0 */
    CRITICAL /* 1 */,
    ERROR /* 2 */,
    WARNING /* 3 */,
    INFO /* 4 */,
    DEBUG /* 5 */);

To apply this setting for Husarnet on every system boot open your /etc/systemd/system/husarnet.service file, and under

[Service]
Type=notify

add following line:

Environment="HUSARNET_LOG_VERBOSITY=3"

In my case end result looks like this:

[Unit]
Description=Husarnet
After=network-online.target
Wants=network-online.target

[Service]
Type=notify
Environment="HUSARNET_LOG_VERBOSITY=3"
ExecStart=/usr/bin/husarnet-daemon
Restart=always
RestartSec=3
NotifyAccess=all

[Install]
WantedBy=multi-user.target

I hope this information was helpful. Please let me know if you have any questions.

Regards, Filip
