Isilon Monitoring Client to Host Performance - Steps to capture the ISILON PCAPS for one client to analyze performance

####Monitoring Client to Host Performance######
Here are the steps to capture  the ISILON PCAPS for one client to analyze performance. Also please run the Wireshark on the host end too at the same time.

And copy isiperf_v3.sh script to the location in step 2.

1. Make the following directory:
# mkdir -p /ifs/data/Isilon_Support/$(date +%m%d%Y)

2. Open a second SSH session and start isiperf.sh (it will run for 10 minutes) in the second session, so it can run in the background while the additional below are performed.
# /bin/bash /ifs/data/Isilon_Support/isiperf_v3.sh -i 10 -e 5 -r 12 -d -g lwio,lsass,netlogon

check and ensure what node client is connected:
#  isi_for_array -s netstat -an | grep "10.252.194.19"

run capture command below on node client is connected to:

4. Start a packet trace with snaplength of 320 from the node.
# ifconfig | grep flags= | awk -F: '{print $1}' | egrep -v 'lo0|ib0|ib1' | while read ifcon; do tcpdump -s 320 -i "${ifcon}" -w /ifs/data/Isilon_Support/$(date +%m%d%Y)/`hostname`.$(date +%m%d%Y_%H%M%S)."${ifcon}".pcap hsot 10.252.194.19 &; done

5. Start pcaket trace on client.

6. Reproduce the issue:

7. Stop packet trace and verify tcpdump has stoped :
#  isi_for_array "killall -2 tcpdump";sleep 2;  isi_for_array ps -auwx | grep tcpdump | grep -iv grep

9. Upload all the files to us:
# isi_gather_info --local-only --nologs -s "isi_hw_status -i" -f /ifs/data/Isilon_Support/$(date +%m%d%Y)
