Some theoretics explanations needed

Question

Good day everyone.
i have to make some custom MP for monitoring some application.
i create one DS for powershell script, one Probe Action for on demand detection, one Monitor Type 2 state.
i use many monitors with different PS Scripts to monitor diferent properties of application.
in production i freqently got this error
can it be because that i use one monitor type with all monitors?
should i create one Monitor type for each monitor? should i create one DS for each Monitor type?
what best parctice to make custom MP with several (about 10) PS Scripted Monitors on loaded system?
AND one more question.
on examples i saw that PropertyBag Object can contains many objects or values.
how can it be used except just output those on alert string or monitor description ?
