AIX Monitoring

Thanks mate for coming up with the query on AIX Performance Monitoring.

Here are few to performance monitoring:

Performance monitored for CPU, Memory, Disk, Network and Virtual Memory.

CPU:

# topas, sar , vmstat : Command to monitor the CPU performance.

The value of "usr+sys" cannot be more than 80%.

Memory:

# sar -m, vmstat, svmon, topas: Command to monitor Memory Peformance.

The value of "avm" and "free" to be noted.

Disk:

# iostat : Command to monitor Disk.

%busy and %tps: Should not be high.

Get the Port in AIX

# netstat -Aan | grep -i "Port Number" : Command on AIX which will tell which program or process running on the respective port.

The ports could be a static port, well known port, dynamic port, registered or un-registered port.

To check the registered port look at the file "/etc/services".

Which Program Is Running On My Port?

# lsof : Litst Open Files, It is one of the utility to find which program or the process running on a specific port.

# lsof -inP | grep "Port Number" 

The command output will show which process is running on which port.
