Monitoring PIAware status?

[psellati]

I did some work with monit and have the basics working.

You need to make one change to the dump1090 start script, as is it won’t create the pid file that monit needs in order to monitor the process. Add the option --make-pidfile before the --pidfile option in the line that starts with “/sbin/start-stop-daemon --start” in /etc/init.d/fadump1090.sh.

Place the following in /etc/monit/conf.d/piaware after you install the monit package::

check process piaware with pidfile /var/run/piaware.pid
  start program = "/etc/init.d/piaware start"
  stop  program = "/etc/init.d/piaware stop"
  if 5 restarts with 5 cycles then timeout

check file piaware.out with path /tmp/piaware.out
  if timestamp > 10 minutes then exec "/etc/init.d/piaware restart"

check process dump1090 with pidfile /var/run/dump1090
  start program = "/etc/init.d/fadump1090.sh start"
  stop program = "/etc/init.d/fadump1090.sh stop"
  if 5 restarts with 5 cycles then timeout
  if failed host localhost port 8080 with protocol http and request "/" with timeout 5 seconds for 4 times within 5 cycles then restart
  if failed host localhost port 199 type tcp then restart

If you want to be able to monitor monit remotely you’ll need to update the listen config in /etc/monit/monitrc. You’ll find documentation under Web Service on digitalocean.com/community/ … gure-monit.

I modified the fadumo1090.sh and piaware files and when I check status it says that the faup1090 is not running and the piaware is not running, see below:

pi@piaware ~ $ sudo piaware-status
dump1090 is running.
faup1090 is not running.
piaware is not running.
dump1090 is listening for connections on port 30005.
dump1090 is listening for connections on port 10001.
piaware is NOT connected to port 10001.
piaware is NOT connected to FlightAware.
dump1090 is producing data on port 10001.
dump1090 is producing data on port 30005.

I modified the file and placed the new code near the end not knowing where exactly it should go as shown below:

pi@piaware /etc/init.d $ cat piaware.work
#!/bin/bash

    echo "Usage: $0 {start|stop|restart|try-restart|force-reload|status}"
    exit 2
    ;;

After making the changes I ran the pi@piaware ~ $ less /tmp/piaware.out command and it came back stating that no log file can be found.

Any help is greatly appreciated!
