[one-users] regular monitoring logged in oned.log

[Hyun Woo Kim]

Hi,

When you said  "3 and 4 may come from Sunstone, clients periodically refresh the information",
can you be more specific about "clients"?

In case of (3) below, when the last ID of virtual machine is N, 
some part of ON seems to mistakenly think that there is one more VM whose ID is N+1
and does something like "onevm show N+1" which produces an error message
(obviously because VM N+1 does not exist) every hour:20.

I would like to know which part exactly does this hourly monitorings against the list of virtual machines.

Thanks,
Hyunwoo

Hi

3 and 4 may come from Sunstone, clients periodically refresh the information. 
Also the sunstone server (or econe-server) caches the user pool to perform authentications, so periodically polling UserPool.

Cheers

Ruben

I observe the following repeated messages in oned.log

1. Every 30 seconds
   - HostPoolInfo
   - VirtualMachinePoolInfo
   - AclInfo

2. Every 10 minutes
   - Monitoring VM "all IDs"
   - Monitoring host "all names"

3. Every hour(:20)
   - UserInfo
   - VirtualMachineInfo

4. Every 15 minutes(00, 15, 30, 45)
   - VirtualMachineInfo

I understand (1) is controlled by SCHED_INTERVAL in sched.conf
and conducted by the sched daemon.

I understand (2) is controlled by the two variables in oned.conf
HOST_MONITORING_INTERVAL
VM_POLLING_INTERVAL
and conducted by VMM.

I would like to know which part of opennebula code conducts (3).

Thanks in advance..

Hyunwoo
