| | Field | Type | Criteria | | ||
| | --- | --- | --- | | ||
| | `seconds_since_last_transition` | float | The number of seconds passed since the last transition in the FSM. | | ||
| | `is_tm_healthy` | bool | `false` if more than `BLOCKS_STALL_TOLERANCE` (60) seconds have passed since the last begin block request received from the tendermint node. `true` otherwise. | |

This practically means that the agent <-> tm communication is all good.

| | `rounds` | list | The last rounds (upto 25) in the FSM that happened including the current one. | | ||
| | `is_transitioning_fast` | bool | `true` if `is_tm_healthy` is `true` and `seconds_since_last_transition` is less than twice the `reset_pause_duration`. `false` otherwise. | | ||

| So, you can usually use `is_transitioning_fast` as a rule to check if an agent is healthly. To add a more strict check, you can also tune a threshold for the `seconds_since_last_transition` and rate of change of `period`, but that will require some monitoring to fine tune it. |

It's also quite easy to add more metrics, although changes to the agent code would be required.
