Hi.
Had sustained cpu at 100% but after I deleted deploy statistics it peaks at whatever available cpu during sync cycle.

Wasn't that fixed in 6.22? It's worth having a look though and checking that there are no deployments clogging up the system. But the symptoms for that are sustained CPU, as I saw it out at a customer

The most recent case like that I worked on.... was leftover remote deploy status data.

John, it’s the standby HUB the acting is not having any cpu issues at all. And it’s 100% related to it pulling data from the acting.

High CPU is always a concern for a TEMS. TEMS is a real time server and should also run low utilization so it can respond promptly,
Two recent cases where a situation created 100% CPU
1) 6K Agents and customer created a MS_Online with sampling interval 5 minutes - wham 100% CPU
2) 14K Agents, MS_Offline with persist=2 and sampling interval 5 minutes - wham 100% CPU.
so I would seriously suggest a PMR and an investigation.

It's never good to have a CPU situation, as it will generate false alarms due to the design of Unix.
It should either be for an extended period of time or for a combination of other factors
e.g
if CPU > 95% for over an hour then alert
or something smarter like if CPU > 95% and CPU run queue/divided number of processors > 5

Right, the worries I have is that our def. cpu situation fires on this one (-:
I have now excluded this hostname from the situation.
As long as the cpu drops and the sync completes I can probably forget about it.

I am not sure you have much to worry about to be honest, Unix is designed to give as much CPU out as possible, especially when the system is quiet. If it was running at constant 100%, and the run queue (column marked q below) was high, then you may have an issue. Unfortunately most of the CPU is User (Us Column below), which means its application bound, and there is not much you can do on the system to tweak this.

CPU running peaking is a bit vague, can you run the following command and post the out here next time it peaks, might help identify the bottleneck a bit further
vmstat 1 10

Hi.
Everytime between
(510BDF05.0000-10:kdyctrl.cpp,3932,"rTEMSSynchThread") TEMS is MIRROR, Synchronizing with HUB TEMS tables.
And:
q(510BE00D.0000-10:kdyctrl.cpp,4045,"rTEMSSynchThread") Sychronization complete. Going to sleep.
The cpu peaks at 99% an nothing unusual in the *_ms_* logs. HUB on Linux RHEL6 6.2.3 FP02.
As soon as sync is complete it drops to close to nothing within seconds.
I need tips on tracing FTP sync, anyone?
