Not sure whether it is not 2.4.1 specific problem. In kea 2.6.0 and the
following logger config, everything works fine. I am running on Ubuntu
22.04.03 LTS
"loggers": [
{
"name": "kea-dhcp4",
"severity": "INFO",
"output_options": [{
"output": "/var/log/kea/dhcp4-all.log",

"maxsize": 102400000

},

Subject: [Kea-users] Kea dhcp log rotate
Dear All,
We are running kea 2.4.1 in our production network (University college).
In the kea dhcpv4 config I have setup below loggers:
"loggers": [
{
"debuglevel": 0,
"name": "kea-dhcp4",
"output_options": [
{
"flush": false,
"maxsize": 10240000,
"maxver": 8,
"output": "/var/log/kea-dhcp4.log",
"pattern": "%d{%j %H:%M:%S.%q} %c %m\n"
}
],
"severity": "INFO"
},
{
"debuglevel": 0,
"name": "kea-dhcp4.bad-packets",
"output_options": [
{
"flush": true,
"maxsize": 10240000,
"maxver": 8,
"output": "/var/log/kea-dhcp4-debug.log",
"pattern": "%d{%j %H:%M:%S.%q} %c %m\n"
}
],
"severity": "ERROR"
}
],
Kea is running on a redhat 8.9
For some reason the old logs are not preserved when they get rotated, only 1
log file is available at any time (latest)
Anyone experience a similar problem?
Thanks in advance,
Kristof
