I build a docker image, everything runs well on my dev machine. But when i deploy the images to my other machine, some services in the container was not able to start.

When we configure inputs.exec , your program/bash script must have exit code 0. If it’s not 0 , telegraf will not send the metrics. This is an example , i have a bash file which will run 10 small scripts myscripts.sh /scripts/file1.sh/scripts/file2.sh/scripts/file3.sh/scripts/file9.sh/scripts/file10.sh Telegraf will run my scripts.sh , the last script file10.sh is very important, if this script does not exit 0 , the entire stack will not send any metrics. There is a trick , we can add exit 0 at the end of the myscripts.sh /scripts/file1.sh/scripts/file2.sh/scripts/file3.sh/scripts/file9.sh/scripts/file10.shexit 0Read More →
