* alarm_clear: Mapping In this PR I mapped all the necessary steps to discover the solution for the ISSUE 6581 * alarm_clear: Documentation and fixes This commit fixes the problem that were present in Netdata and it also updates the documentation of the functions and Netdata. * alarm_clear: shell script The original implementation did not have a shell script, here I begin to fix this * alarm_clear: shell script It is necessay to verify why make is not producing the same binary than cmake and finish the changes in the script * alarm_clear: adjust in health.c I rewrote the health.c to be more readable, but I discovered the problem I had in the last few hours were due kernel update * alarm_clear: script changes In this commit I am bringing the final version of the script that test the alarm repetition * alarm_clear: script fix and remove comments IN this commit I am fixing the shellcheck errors and removing some debug messages that were present in the code while I was developing * alarm_clear: Format The health.c had wrong tabulation, this PR brings back the pattern of space as tab for this file * alarm_clear: Script The script was using killlall that is not more present in all Linux distribution this commit removes this and bring the new way to stop Netdata * alarm_clear: return to previous tabulation I am bringing back the old tabulation here and I will create a new PR exclusively for this * alarm_clear: Remove comments I am removing comments from this PR to keep the focus in the major problem * alarm_clear: Remove comments 2 I forgot one comment * alarm_clear: New variable I am appending a new variable in the check before the rebase, because the health.c changed in other file has a direct relationship with what I did here until now * alarm_clear: Fix clear repetition With this last commit, I am bringing a new way to raise the clear alarm, but it is not repeating more with this fix, it displayed one time when it is cleaned and it will display the message again, if and only if, the alarm was raised.
