Very good question thanks for asking.
I have a daily routine task to monitor all the device dashboards, notifications etc.
I have a routine task once in a month to check all the device means as follows:
- Check the cable of the Device (LAN and Power)
- Check the LEDs of the Device (sometimes you are not notified by the software or you misses to see.
- Check for the updates if anything available by the manufacturer
I have a biannual task (or as per required) to perform cleanup of all the device dust in the racks. Where I work has no proper room for the server rack so it quickly stores all the dust and debris inside the devices and racks.
At present this is what I think of I will update the post If I remember anything more.
