There is a lot of potential in system status module in Hawat and a lot of room for improvements. Start with displaying processing statistics of real-time message processing modules and then consider another possibilities for improvements.

Implemented first working proof of concept of displaying internal daemon component counters. However current implementation will not properly display counters for paralelized modules.

added Done 10% S-In Progress labels and removed Done 0% S-New labels

This task will take a lot more time to complete. I am moving it to the next version and instead decided to fix the issue with heavy sequential scans in list precalculation queries #4252.

Sometimes, I am using the system status view, I think it can be helpful. So I would like to improve the view.

The description of this issue is quite vague, so I was thinking of my own improvements.

Here are my ideas:

• There are 'unknown processes' like precache and reporter, we could also display information about those modules.
• The bug mentioned in https://gitlab.cesnet.cz/709/migrace/homeproj/mentat-project-05/mentat-ng/-/issues/4218#note_198730 is still present.
• I think it would be nice to parse the configs of cronjobs and display them in a format 'Runs every Sunday at 1 am.' or something similar.
• Maybe we could also display the last N lines of log files or the last run of a module.

It's possible that we will get rid of mentat-controller in #6928, so this should wait until that issue is resolved.

Relation Blocked - Feature 6928 Reconsider Mentat process management

Relation Relates - Feature 4447 System status monitor should also report on warden-filer status

added S-Waiting label and removed S-In Progress label

Function module_status in lib/mentat/system.py could also handle the following states:

• Process is dead and /var/lock lock file exists (return STATUS_RT_DEAD_LOCK_EXISTS
• Process or service status is unknown (return STATUS_RT_UNKNOWN)
