How to get the current status of the Kura from command line [message #1758974]

Hello,

how to get the information whether Kura is started or stopped from the command line?

When I enter this;

pi@pi:$ sudo /etc/init.d/kura status 
.

the console only shows a period (.) I do not know if it is the correct way to look at the current "running" or "stopped" status of Kura.

Thank you in advance.

Thank you for your answer.

I have entered what you said and the result is;

● kura.service - LSB: Kura initscript
   Loaded: loaded (/etc/init.d/kura)

Hint: Some lines were ellipsized, use -l to show in full.

Even if I could not connected to Kura Web UI and the Kura via Eclipse, the message above says in the third column, active (running) since ....

Two related questions;

1. What is active in the message above?

2. When I could not connect to Kura Web UI, what should be started?

Thank you in advance for your help.

Hello,

If you just want to know if Kura is running, you can run the command recommended by Said. You can also run

ps aux | grep java

If you have multiple Java processes running, you can grep for the PID of Kura found in /var/run/kura.pid.

It looks like Kura is running on your system. If you are having trouble using Kura, check both log files (/var/log/kura-console.log and /var/log/kura.log) for errors. You should also check the 'ss' and 'ls' commands from the OSGi console to make sure all components are active.

Thanks,

Thanks for the answer but I still did not understand.

If the message says that the Kura is running, why could not I connect to Web UI (after I issued sudo /etc/init.d/kura start, I could connect again)?

Hello,

Unfortunately I am not sure. One possibility is that you have multiple instances of Kura running. If Kura attempts to start along side an already running instance of Kura, the web bundle (Web UI) will not start because the HTTP port is in use. I would recommend restarting your device. Kura should start automatically.

Thanks,
