We have set "Delay between checks" to 5 minute for a particular monitor, however sometimes we don´t see the check happening and we are not sure whether the was an error or whether the check was performed successfully.
Why are not we seeing the check happening every 5 minutes in ASM logs?
It could be possible the monitor has just few stations selected (eg: 3 stations) so if the stations are overloaded or if they go to maintenance mode it won´t display any information
within ASM logs as the check didn´t complete due to lack of available monitoring stations. You can add more checkpoints to the pool as this will reduce the problem.
