Device Limit & Drop Check

Sanjay Shah3 years ago

I have 1000 devices on traccar. I find that at times device don't get connected to server. And some time is see delay in response.

I have set parameters as guided in Optimization page. Still I see that devices get disconnected abruptly and fail to reconnect unless they are manually rebooted.

my timeout parameters in config are

web.timeout - 90000
server.timeout - 250
status.timeout - 250

my system ram is 32 GB
mysql is 5.7

I m using AWS EC2 Linux Instance

any ubuntu command to check if the file open is exceeding the permitted limit or heap size is low.

Also I m using websocket to see real-time tracking in web and app.

You will see errors in the log if exceed the limit.

Are devices disconnect by themselves? That probably means some device issues. What makes you think it's a server problem?

that was quick reply. Device disconnect by themselves as i see they go online. but when i send sms command it show GPRS Link up & Server Link also Up. But on server i see it disconnected, Then i do manual reboot and it appears online.

I checked log for such error, but none found. Today i will enable full trace and see if that is reported

is there any command line to check number of open connections vs the open connection allowed....

Typically what no. of devices i can connect to one server in AWS EC2 instance with 32 GB Ram
