Re: Disk Bottleneck & Network Bottleneck
1) bdf on the system. Clean up the full file system problems. See if your other problems go away.
2) Check statistics when the system is running normally and I/O isn't backing up, waiting to write to disks that might be full.

Re: Disk Bottleneck & Network Bottleneck
Steven,
I have attached the output of the bdf which shows the 2 logical volume lvol10 and lvol13 are having space less then the 45%

Re: Disk Bottleneck & Network Bottleneck
regarding file system full msg in messages file
/oracle/PRD/oraarch and /eu_diveline
Arch folder is probable to get full.
Are you sure that you getting same error again?
for bottle neck you have to see the which disk is having IO.

Re: Disk Bottleneck & Network Bottleneck
Instead of looking at old stale dmesg data, look at syslog.log.

Re: Disk Bottleneck & Network Bottleneck
You printed dmesg - old info
You printed the Alarm screen on Glance - may be old info, hence why they have a Clear option in the toolbar.
Use syslog, use the clear button in Glance to ensure you're not looking at old info. Another good one to clear first is vmstat with a vmstat -z, so when you see a value in 'paged-out' you know it's an issue and not just a past occurance.
Confirm that you are sending 'current' conditions to be addressed.
Kindest regards,
Rita

Re: Disk Bottleneck & Network Bottleneck
I have checked syslog.log their was message related to Filesystem but i am not able to figure it out. But currently i am getting similar alert for the /dev/vg01/lvol4 which is 61%. I have attached the error log which i am getting today from syslog.log.
------------------------------------------
As far my research i found that
Disk bottleneck message is related to disk access performance, not for available disk space. Usually its due to application overloading on an individual disk/disk subsystem it may also be due to faster disk utilization I/O operation.
Network bottleneck probability message is related to network traffic We can check the Network interface statistics for any collision and any other erroneous packets, choking the network.
