If it doesn't find it, then + the app is considered not to be running. + + [2] An application PID file -- JKEEPALIVED can fetch a file which is + supposed to contain the most up to date + PID of a given process, writen by the app + itself. If that PID isn't found, then + the app is considered not to be + running. + [3] A PID -- This is deprecated and several improvements could have + been made to it. I didn't do it because this was plain + stupid. Do not use it. + + +JKEEPALIVED searches for all this information in /etc/jkeepalived.d/jkeepalived.conf +This file has a simple syntax (# denotes a comment, inline comments are supported): + # freq type type_data start command arg1 arg2 ... argN + +First, the frequency, freq, in seconds, of check. This means that after 'freq' +seconds, jkeepalived will check to see if an app is running. + +Then, "type", determines the method to determine if the app is running. Possible +values are: "pid" (deprecated), "proc_name" or "pname", or "pid_file". +proc_name corresponds to [1], pid_file corresponds to [2] and pid corresponds +to [1]. + +Thirdly, "start command" determines the string to execute the app if it isn't +running. + +Lastly, all arguments to the app can be defined and separated by spaces. +All arguments but "freq" can be quoted ("like this"), or unquoted(like_this). + +Example file: + + # freq type type_data start command arg1 arg2 ... argN + 3600 pid_file "/home/jorl17/.jorl-package-updater.pid" "jorl-package-updater" --background + 5 process_name "pcmanfm" "pcmanfm" + 5 process_name "volcontrol" "volcontrol" + +JKEEPALIVED logs its messages to syslogd. + +WHY? +---- + Why not? I wanted something to do this because some of my + background-applications are important. I don't want to check if they + have crashed or purely gone away. Hence, I decided to design my own + solution, knowing that there are many others. + +GPLv3 +----- + All code is GPLv3. The source has the license info.
