 Description   

Steps to reproduce:

  1. Create item vfs.dir.size[D:\oracle\fast_recovery_area\dbname]
  2. oracle db every night deletes files from D:\oracle\fast_recovery_area\dbname forming a backup.
  3. oracle db and user can't delete files from D:\oracle\fast_recovery_area\dbname
    {2023_04_01}

    because files are held by Zabbix Service

Result:
See screenshot.
Oracle db and user can't delete files

Hello Alex,

Please confirm Agent type (C (1) or Go (2)) and Agent version.

How many files do you have in this directory (and total size) and how long does it take to execute same check from the Zabbix Server/Zabbix Proxy with zabbix_get? 

time zabbix_get -s <ip> -k 'vfs.dir.size[D:\oracle\fast_recovery_area\dbname]'

real    0m1.806s
user    0m0.174s
sys     0m1.161s

210-230 items add every day in subfolder and every night this directory D:\oracle\fast_recovery_area\dbname is cleared

Total size 22-25Gb.

Do you have storage IO performance metrics like latency, IOPS/sec performed during backup time?

Comment by Alex [ 2023 Apr 14 ]

No. Please tell me the template for Windows Server 2016 x64 is suitable. I'll measure tonight.

I updated the template at the link you specified, but the item (as an example) perf_counter_en"\PhysicalDisk({#DEVNAME})\Disk Reads/sec",60 did not appear.

When I tried to add it manually, I got a message that the item already exists.

I went to "Discovery rules" -> "Physical disks discovery" and tried to click "Test" and got an error.

Deleted the templates completely and tried to add again. Got an error: Graph "{#DEVNAME}: Disk utilization and queue" already exists on "SRVORACLE" (items are not identical).

But there are no graphs on the specified host at all. I read that similar behavior may occur due to a large version difference between the server and the agent.

Downloaded and installed Zabbix agent 2 v6.0.16. The template was no added to the existing host.

I created a new item and specified the same ip as the existing one by adding the desired template.

All necessary items appeared.

Tomorrow I will send the metrics you requested.
