{#DEVNAME}: Disk read/write request response are too high

{#DEVNAME}: Disk read/write request response are too high (read > {$VFS.DEV.READ.AWAIT.WARN:"{#DEVNAME}"} ms for 15m or write > {$VFS.DEV.WRITE.AWAIT.WARN:"{#DEVNAME}"} ms for 15m)

Hello!

Im having this trigger email alert so many times in a day, im trying to trace what's is going but I have no clue about...

Its a new appliance with 500Gb SSD 50Gb of RAM

Looking for the IOSTAT, TOP, IOTOP i cant see nothing even in Zabbix daily statistic o `ms` read and write slowdown... I tried to change the trigger to 30mins but still happening with a minor frequency.

I would like to some advice about this trigger getting fired a lot of times without a reason.

About this server, i was preparing it to receive our new DB but actually there's nothing in production with in this server.

No cron, no backup schedule,no data transferring,no raid, a single new SSD with no use. So, how can I debug this possible problem (if it really is) and how can i get the application which is messing it? The mail is sent in a random hour, no pattern, 2am,12;12pm and so on...



anyone experiencing the same scenario?


Thanks in advance.

Hi
I also have this issue quite often.

[cyber]

Trigger name does not really give others that info, what would be needed to analyze things...
I suppose it is the trigger from "Template Module Linux block devices by Zabbix agent active" ?
{Template Module Linux block devices by Zabbix agent active:vfs.dev.read.await[{#DEVNAME}].min(15m)} > {$VFS.DEV.READ.AWAIT.WARN:"{#DEVNAME}"} or {Template Module Linux block devices by Zabbix agent active:vfs.dev.write.await[{#DEVNAME}].min(15m)} > {$VFS.DEV.WRITE.AWAIT.WARN:"{#DEVNAME}"}
{$VFS.DEV.READ.AWAIT.WARN} and{$VFS.DEV.WRITE.AWAIT.WARN} have been set by default to 20ms...Looking at trigger expression, it will trigger if minimal value during 15m is higher than 20ms... (everything is higher than that)
So please, look at the data, what is gathered. Maybe that value of 20ms does not suit your environment, Maybe its too low? Maybe it is normal to have those times over 20ms ?Adjust it (Macros in template..).
