PCMonitorSrv consuming I/O disk reads

Hi,

is it normal that PCMonitorSrv is hanging on so much DISK READ I/O? It consumes 90% of all disk I/O reads on Windows Server, where all Windows services, Exchange and Oracle DB do not consume alltogether the rest 10% disk I/O:

Hi,

not that I am aware of. Same for plugins.

BTW...when I look at momentary I/O impact, PCMonitorSrv.exe is NOT consuming a lot of I/O at the moment. But as counter is so big, I guess it is using intensive I/O at some other times, maybe at night.

Hi Chris,

did you ever resolve this issue? I have dozen of servers with same symptoms - Pulseway service is top disk I/O Reader:

Typically I have NO plugins installed, and under settings on all servers selected those features:

  • SYSTEM --> NETWORK --> Display Ping Response from some IP
  • SYSTEM --> SERVICES --> Selected to manage all Auto-start services
  • SYSTEM --> FILE BROWSER Enabled
  • SYSTEM --> REMOTE DESKTOP Enabled
  • MODULES --> MANAGE --> Active Directory
  • MODULES --> MANAGE --> Exchange
  • MODULES --> MANAGE --> IIS
  • MODULES --> MANAGE --> SQL Server
  • MODULES --> MANAGE --> Windows Server Backup
  • NOTIFICATIONS --> Services
  • NOTIFICATIONS --> Storage
  • NOTIFICATIONS --> Hardware --> CPU temperature
  • NOTIFICATIONS --> SERVER MODULES --> AD (Locked User)
  • NOTIFICATIONS --> SERVER MODULES --> Exchange (Messages Que longer than 20)

That's more or less all I have.

It is hard for me to test, because I would need to disable all features and enable them one by one, reboot server and left it over for a week or so to see results.

Hi Labsy,

Thank you for your detailed report. Can you please turn off the storage notifications to see if this decreases the I/O read growth?
