disk read request avg wait time

[jronpaul]

hello !.
i have zabbix monitoring my machines at home.
running mint Linux Mint 20.3 Una \n \l

got an alert for
sdb: Disk read/write request responses are too high (read > 20 ms for 15m or write > 20 ms for 15m)

this is for a MDADM raid 0
mdadm -D looks good.
both disks are identical models

smartctl looks good
the only thing i did recently was shut it down and upgrade the memory... swap is not on this disk..

im not sure why its high read on sdb ... even when its unmounted..

so i assume its zabbix checking the disk, that said why just sdb?

here is zabbix monitoring over one day.. you can see the sudden spike and its only sdb read

Disable david for a day and you may know if it causes requests ..
zabix and the like is for mission critical application. Do you run any such? If not remove it totally. After all it taxes resources.

im not even sure if zabbix is causing it..
it was just speculation..

im using zabbix to collect data on my home machines..., laptops etc.etc.

what else is as good as zabbix ? i tried cockpit but wasnt impressed.

Disable zabix for some time and see if it makes a difference.

[jronpaul]

i could try that..

any suggestions for a zabbix alternative?
