 >>>> : Fri Oct  2 15:20:30 +03 2020 - [INFO] Avalanchego node is healthy ! -  health.getLiveness result.healthy=true hostname=oracle-1
 >>>> : true

./check_avalanchego_status.sh test
 >>>> : Fri Oct  2 16:25:53 +03 2020 - [TEST] [TEST] Avalanchego node TEST message !!!..
 >>> sendig Fri Oct  2 16:25:53 +03 2020 - [TEST] [TEST] Avalanchego node TEST message !!!..
{"ok":true,"result":....................................."date":100045154,"text":"Fri Oct  2 16:25:53  03 2020 - [TEST] [TEST] Avalanchego node TEST message !!!.."}}

4-) Check crontab - Script will check avalanchego heath status every minutes and if NODE is not healthy it will alert via telegram and if NODE is healthy again it will send a recovery message

# list crontab
crontab -l
