Trying to figure out how to increase the SMZ size for Frigate app running it ZimaOS+.
I have tried from Frigate forum instructions but can’t find where to do in ZimaOS.
In your docker yaml for frigate. I have it setup as follows:
name: frigate

Sorry for the messed up layout, I’m pasting this from my phone. Note the shm_size tag. Put that in your own yaml and configure to your needs.
Ok that did not work, but I found how to get it in.
In Zima frigate Settings< Advanced< In (form) I used Environment Variables: Name<shm_size>Value:<“268435456”> for 256MB. This worked and now shows up in the yaml under entry point environment:
Now my other issue is: frigate.comms.mqtt
Message
Unable to connect to MQTT server: Invalid host.
I have MQTT enabled: true in frigate config, bu tget that error.
And I noticed you have port 8971 UDP in that config, is that for mqtt?
I have MQTT installed in Zima but I don’t know what settings in either Frigate or MQTT to set.
Here is MQTT yaml:
services:
mosquitto:
command:
- sh
- -c
- |-
if [ ! -f "/mosquitto/config/mosquitto.conf" ]; then
echo -n "No config file found. Create one... "
{
echo "# config generated on $(date +%Y.%m.%d\ %H:%M:%S)"
echo "allow_anonymous true"
echo "listener 1883"
echo "persistence true"
echo "persistence_location /mosquitto/data/"
echo "log_dest file /mosquitto/log/mosquitto.log"
} > /mosquitto/config/mosquitto.conf
if [ $? -eq 0 ]; then
echo "done."
else
echo "error."
exit 1
fi
fi
echo "Starting Mosquitto"
