Hello everyone!
I'm troubleshooting a performance issue on my PostgreSQL stack that is running on EC2 instances in AWS.
The instances have EBS GP2 volumes with 2048GB and a total of 6144 IOPS.
You can see below that Zabbix reports the /pgsql volume to reach 100% of utilization. And the timing of those are exactly when I have the performance issues. However, looking at the AWS dashboard, I see that the disks are not reaching their limit.
So, I would like to know what does vfs.dev.util[] mean? Which Linux command does vfs.dev.util[] represent? I wanna know if that graph is valid and is showing real and valid data.
Thanks in advance!
