Read And Write to Disk- If an application writes to a file system, then it must be able to read from the file system. Otherwise, if the application cannot read from the file system, it may crash.
Processes Functioning- A liveness check may test proxies, but it may not check the actual application links. However, local health checking goes beyond the basic check to verify that the processes are actually working properly.
Missing Processes- Make sure that support processes are working correctly. If they don’t monitor them deeply enough, they may miss some issues, which could be hard to spot and require more time to fix.
