[Feature Request] Script hook on view refresh cycle.

[RimBlock]

Firstly thanks to Swar and the other contributers for this great system.

There are a number items that people would like implemented that have not made it in yet.

i.e.

• Job stall check.
• Disk space checks and drive activation / deactivation depending on state.
• Post job plot moving.
• General system heathchecks.

One quick way to help people with this maybe to add the ablilty to run a script on each "view" cycle. Frequency is controlled by view refresh timer.

Advantages

• People can run healthchechs etc without needing to merge code with the project.
• Saves people the need to play with Cron or MS Scheduler etc and to keep everything in the Swar bundle.
• People can also share scripts and the most popular ones could be evaluated for a future feature addition.
• Doesn't limit script runs to only after a plot has finished (although that hook will be great to have when it is merged and released).

Examples of scripts for constand checks.

• Run a script that check to see if a jobs logfile has updated in the last 5 minutes. If not, send a notification, scape the jobs PID and polt ID, kill the job, remove the PlotID's tmp files.
• Run a script that checks if a disk is filling up, amend the config.yaml and # that location out.
• Implement tmp and destination location rotation. Have pools of tmp / dest paths (one for SSD / one for NVME, one for HDD) and amend the config.yaml with the next in the pool as one is used for a new plot process.
• General system health checks and alerting

for monitoring and health checking: why don't you run a monitoring and health checking tools? if you don't want to mess with your own, there is a chiamon for you. also, swar plot manager is exposing limited set of metrics via prometheus.

btw, i like the idea to have a "Job stall check" (I implemented this in my own plot manager which I can open source in the future =p still under development).

Yep, I am working on an ELK setup for that in my own setup. Was thinking more for others. Thanks for the chiamon link.
