Currently loading of the monitoring host is done from iepm-bw.slac.stanford.edu.

  • Enter the node into the 'NODES' data base.
  • Enter the node into the 'MONHOST' data base.
  • On iepm-bw.slac.stanford.edu, make a tar file including all the code.
    Code Block
    
cd /afs/slac/package/netmon/bandwidth-tests/v3src
tar -cvf dist.tar -T dist.scripts.list
scp dist.tar iepm@<fully qualified monitoring host name>:/home/iepm/dist.tar
  • Log onto the new monitoring host node under the 'iepm' account.
  • Execute the following to install the source code
    Code Block
    
mkdir v3src
cd v3src
tar -xvf dist.tar
  • Now configure the 'config' directory. The following files may need configuration:
    • 'cleanup-list' - should be configured correctly. If there are processes which are known to hang, they should go in this file. 'bw-cleanup' uses this file to clean processes known to hang (now or in the past). If the process with the name in this list exists longer than the number of minutes indicated on its line, it will be killed.
    • 'owampd.conf.template', 'owampd.limits', and 'owampd.keys' are configuration files for owamp.  'owampd.limits' and 'owampd.keys' should be ok.  Look at owampd.conf.template. 'datadir' and 'vardir' are defined to be '/home/iepm/owamp/data' and '/home/iepm/owamp/run' respectively. If this is ok (recommended

...

    • default), save 'owampd.conf.template' as 'owampd.conf'. Then create the directories:
      Code Block
      
mkdir /home/iepm/owamp

...

    • 
mkdir /home/iepm/owamp/data

...

    • 
mkdir /home/iepm/owamp/run

...

    •
    • 'servers.alive' may beed to be configured. This is the file that has the information for starting the servers. It is used by 'keep-servers-alive' to start, and if necessary, restart the servers. For a standard monitoring host, this file should be:
      Code Block
      
bw-iperf-server,bin,-s -p 5000 -w 20M
thrulayd,bin,
pathload_snd,bin, -q -i
map-updated,,
pathchirp_snd,bin,
owampd,bin, -c /home/iepm/v3src/config -Z >& /tmp/owampd.log &
      The first field is the name of the script. The second field is the directory in $iepmSrcDir where the script resides. The third is a list of parameters to start it with.
    • Make copies of /etc/my.cnf and /etc/iepm.cnf in the config directory. They are used to provide configuration information to the CGI scripts.
      Code Block
      
cp /etc/my.cnf /home/iepm/v3src/config
cp /etc/iepm.cnf /home/iepm/v3src.config/iepm.cnf.<aliasname>
