Red Hat Bugzilla – Bug 1306385
/etc/cron.hourly/miq_top_hourly calls /bin/miqtop which does not exist
Last modified: 2017-08-30 04:02:48 EDT
Description of problem: /etc/cron.hourly/miq_top_hourly calls /bin/miqtop which does not exist. /bin/miqtop.sh does exist. On CF 3.2 this appears to break the ability for top_output.log and vmstat_output.log processes from restarting automatically hourly. Version-Release number of selected component (if applicable): 5.4.4.2.20151130143928_89a28ce How reproducible: Install a current 3.2 appliance Steps to Reproduce: 1. view /etc/cron.hourly/miq_top_hourly 2. try to run command from last line without redirecting stdout and stderr 3. view /bin/miqtop.sh and note error there as well for creation of cron job. Actual results: If top or vmstat logging processes die, they do not restart. Expected results: If top of vmstat logging processes die, the cron job will restart them. Additional info: This process appears to have been reworked in 4.0. Not sure what restarts the processes there at this point, but there's no incorrect entry in the cron file and the cron file has been renamed.
For version 5.5 these services were broken out into systemd units and the timestamp functionality was left as a cron job. Systemd allows for options to restart services if they exit with a failure state. This change can be made for 5.5 and upstream. For 5.4 we can fix the typo in the file, and that should fix the issue.

Killing the processes (kill -9) running miqtop and miqvmstat (can be found via `systemctl status <service>`) should cause them to be restarted automatically (can be seen in the logs yielded with `journalctl -u <service>`)
