AIX’s built-in iptrace utility collects more information than tcpdump, and its companion ipreport tool provides better decoding.
The legendary packet-sniffing program popular on other Unix flavors, tcpdump, is available in AIX but may not be the best tool for the job.
To get the same information for virtual memory, run svmon -Pgt 3.Ħ. Pid Command Inuse Pin Pgsp Virtual 64-bit Mthrd 16MB For example, to discover the top three users of real memory Memory comes in two varieties, virtual and real, and despite the “v” in the svmon command name, it can report on real memory usage as well as virtual. Troubleshooting application performance problems typically requires first verifying that resource starvation isn’t the cause, and the most common resource that applications run out of is memory. Timeout Errors: 0 Packets Discarded by Adapter: 0 Late Collision Errors: 10007 Receive Collision Errors: 0ĭeferred: 281379 Packet Too Short Errors: 0 Max Collision Errors: 216 No Resource Errors: 0 Specifying ALL for the user name lists all user attributes for all users, or if you specify an attribute using the -a option, all of that attribute for all usersĪIX’s entstat tool delivers the stats for one interface at a time, with crystal-clear captions, making it easy to assess an interface’s error conditions. Without -f, all the attributes are strung together on one line, which may be more convenient for parsing using regular expressions. The -f option requests attributes in stanza form, indented under the user name, one attribute per line. Lsuser command lets you query the attributes of an individual user, and AIX by default stores more than 50 attributes, including a user’s groups, home directory, shell, quotas, and last-login timestamps. lsdev: List Attached Devices and Their Characteristicsįor example, to get a list of network interface cards, runĮn0 Available 07-08 Standard Ethernet Network InterfaceĮn1 Defined 07-09 Standard Ethernet Network InterfaceĮt0 Defined 07-08 IEEE 802.3 Ethernet Network InterfaceĮt1 Defined 07-09 IEEE 802.3 Ethernet Network Interface
