  1. TIM:

To collect the logs:

  1. Go to TIM setup page : http://<hostname>/cgi-bin/wily/packages/cem/tim/index
  2. Using the link “Collect Tim Log and Configuration files” the logs, configuration, Packet statistics, Transaction statistics and core dump files can be downloaded in the timlogs.data file which is aleady zipped.

To increase the log size:

  1. Go to TIM setup page : http://<hostname>/cgi-bin/wily/packages/cem/tim/index
  2. Using link "Configure Tim Settings" and set MaxLogSizeInMB = 200 will give the size of the logs.

To enable the traces:

  1. Go to TIM setup page : http://<hostname>/cgi-bin/wily/packages/cem/tim/index
  2. Using the link “Configure Tim Trace Options” and Enable all the Tim Trace options (Left column). CA Support may advise on specific trace options to set for a particular problem scenario. Also note that setting all trace options on an MTP TIM can cause TIM processing of pcap files from MTP feed directory to be impacted. 

To capture a pcap file on the Standard TIM server:

  1. SSH to the TIM server. 
  2. Run this command to capture packets:

    tcpdump -s 50000 -i eth0 -w test.pcap 

  1. Once the command is running it will start to listen the packets on the port.
  2. After few minutes please do ctrl+c to stop the listening.The captured packets file will be on the directory where the command ran. 

Note: change the eth* port according to which TIM NIC is the monitoring port.

To capture a pcap file on the MTP TIM server:

  1. SSH to the MTP as user netqos
  2. The command /opt/NetQoS/bin/buildpcap command can be used to extract a pcap from the MTP vertica database. To see a full list of parameter options type:

/opt/NetQoS/bin/buildpcap --help

An example command to capture data for web server 10.0.0.1 for a 5 minute period between 10.30-10.35 AM on Nov 25 would be:

opt/NetQoS/bin/buildpcap --feed 0 --start-datetime 20151125-10:30:00 --end-datetime 20151125-10:35:00 --filter-server-address 10.0.0.1 --filter-server-port 443 --output-file /tmp/test1.pcap
