System Manager GUI access issue or the following alert appears:
ddr_procmon: ALERT: MSG-PMON-00012: Cannot restart /ddr/bin/sm_em. Setting state to FAILED.
The alert can be seen on the console itself and in messages.engineering.
There will be no alerts seen in #alerts show current
Note: This alert has also been seen with DDVE
The procmon alert is commonly seen;
Procmon's job is to restart a process, if it has failed/exited. And if a process repeatedly keeps failing, procmon throws an alert about it. Earlier Releases: What changed in last release:
Procmon has been configured to monitor sm_em process. As soon as sm_em dies, procmon restarts it.
sm_em internally starts Apache inline, sm_em keeps waiting at this line, until Apache is running. If Apache quits for any reason, sm_em will move forward and exit. Procmon is monitoring sm_em, it restarts sm_em, and as a result Apache is started again by sm_em.
sm_em is starting Apache in background, Therefore, it doesn't stop execution of sm_em. sm_em moves ahead and quits.
Procmon is still monitoring sm_em. It restarts sm_em, and throws alert when sm_em keeps on quitting every time.
Procmon's job is to restart a process, if it has failed/exited. And if a process repeatedly keeps failing, procmon throws an alert about it.
What changed in last release:
Restarting the system's web service, by disabling then re-enabling them using the below commands on DD CLI/Putty can bring up the GUI if it's inaccessible but will not suppress the alerts:
ddr## adminaccess disable http
ddr## adminaccess disable https
ddr## adminaccess enable http
ddr## adminaccess enable https
Proceed with the upgrade.
Upgrade DDOS to 18.104.22.168 or above
