AIX Performance Tools
Top 5 AIX performance tools used are:
1. Vmstat
2. Topas
3. Iostat
4. Netstat
5. Ps
Vmstat:
- Gives:
i. Traps
ii. Virtual memory
iii. Paging
iv. CPU
v. Number of interrupts per second
vi. Kernel threads
Iostat:
- Gives:
i. CPU usage
ii. i/o of disk, adapter, ttys
iii. i/o subsystem
topas:
- Gives:
i. logical partition information (# topas -L)
ii. processes(# topas -P)
iii. file system(# topas -F)
iv. disks(# topas -D)
For CPU Monitoring,
Admin can make use of:
- netpmon
- sar (sar -u)
- topas
For memory monitoring,
Admin can make use of:
- svmon
- netpmon
- filemon
Svmon and filemon are perfagent tools.
For I/O subsystem,
Admin can make use of:
- fileplace
- filemon
For Network,
- tcpdump
- netpmon
For processors and threads,
- svmon
- kdb
- fuser
- prof
- truss
nmon will give entire OS performance information.
Mpstat: this command displays performance statistics of all logical CPU in system.
Lparstat: reports LPAR related information and statistics.
Traced based commands:
CPU Monitoring: tprof, trace, trcrpt
Memory: trace, trcrpt
i/o subsystem: trace, trcrpt
network: iptrace, trace, trcrpt
processes and threads: tprof, trace, trcrpt
SAR: System Activity Records: it collects reports and saves system activity information.
Happy Learning!
