Product and Software: This article applies to all Aruba controllers and ArubaOS 3.3.2.24 and later. Aruba OS 3.3.2.24, 3.3.3.3, 3.4.2.1 and later builds have an enhanced memory monitoring routine. The memory monitor now saves up to 30 logs of debugging information. The logs rotate on a first-in first-out basis so that the most recent log contains the most current debug information. These logs include information on system memory, irregular application memory usage, large files in the ramdisk, large pending tx/rx queues, and memory block usage. This information can be leveraged by Aruba Networks technical support while analyzing nanny post-crash reports. The memory monitoring logs can be retrieved from the controller by issuing the 'tar logs' or 'tar logs tech-support' commands at the CLI or by downloading the logs from the WebUI. These logs are stored in the tarred logs under \var\log\oslog\memlogs. In this folder, you can see a compressed mm_logs.tar.gz file. Unzip the mm_logs.tar.gz file to extract several logs named memlog.01, memlog.02, and memlog.03. The following sample output of one of these memlog files shows the memory-related information that is collected. memory snapshot: Sun Oct 24 18:32:29 2010 ========================================= Memory (Kb): total: 256060, free: 38497 9448 /mswitch/bin/auth 5544 /mswitch/bin/profmgr 5208 /mswitch/bin/l2tpd -D 4396 /mswitch/bin/wms -l 5 4248 /mswitch/bin/isakmpd 2392 /mswitch/bin/snmpd 1856 /mswitch/bin/udbserver 18232 /mswitch/bin/fpapps 17300 /mswitch/bin/cfgm 1712 /mswitch/bin/mobileip 1512 /mswitch/bin/ospf 14732 /mswitch/bin/stm 1440 /mswitch/bin/slb 1380 /mswitch/bin/dbsync 1356 /mswitch/bin/pptpd -f 1208 /mswitch/bin/pim auth : 9/18M (cur/typical) 0M over stm : 14/18M (cur/typical) 0M over wms : 4/18M (cur/typical) 0M over cfgm : 16/22M (cur/typical) 0M over fpapps : 17/20M (cur/typical) 0M over profmgr : 5/ 8M (cur/typical) 0M over isakmpd : 4/ 6M (cur/typical) 0M over l2tpd : 5/ 8M (cur/typical) 0M over mobileip : 1/ 4M (cur/typical) 0M over ospf : 1/ 4M (cur/typical) 0M over pim : 1/ 2M (cur/typical) 0M over pptpd : 1/ 5M (cur/typical) 0M over dbsync : 1/ 3M (cur/typical) 0M over slb : 1/ 4M (cur/typical) 0M over snmpd : 2/ 5M (cur/typical) 0M over udbserver: 1/ 4M (cur/typical) 0M over Large files under /tmp ====================== /tmp/.var/log/oslog:-rw------- 1 root root 1500023 Oct 24 18:28 filter.1.pcap %CPU S PID PPID RSS CMD 0.0 S 820 669 18232 fpapps 0.0 S 821 669 18232 fpapps 0.0 S 822 669 18232 fpapps 0.0 S 823 669 18232 fpapps 0.0 S 824 669 18232 fpapps 0.0 S 825 669 18232 fpapps 0.0 S 826 669 18232 fpapps 0.0 S 827 669 18232 fpapps 0.0 S 828 669 18232 fpapps 0.0 S 831 669 18232 fpapps 0.0 S 832 669 18232 fpapps 0.0 S 798 669 18232 fpapps 0.0 S 799 669 18232 fpapps 0.0 S 939 669 18232 fpapps 0.0 S 669 668 18232 fpapps 0.0 S 670 669 18232 fpapps 0.0 S 668 526 18232 fpapps 0.0 S 793 669 18232 fpapps 0.0 S 797 669 18232 fpapps 0.0 S 748 669 18232 fpapps 0.0 S 812 669 18232 fpapps 0.0 S 661 526 17300 cfgm 0.2 R 542 526 17036 fpcli 0.0 S 12782 542 17036 fpcli 2.2 S 709 526 14732 stm 0.0 S 528 526 12316 arci-cli-helper 0.3 S 708 526 9448 auth 0.0 S 706 526 5544 profmgr 0.0 S 685 526 5208 l2tpd -D 0.4 S 700 526 4396 wms -l 5 0.1 S 693 526 4248 isakmpd 0.0 S 966 761 3808 apache/bin/httpd -DFOR 0.1 S 726 526 2984 trapd 0.0 S 576 575 2728 mysql/libexec/mysqld -
