Multipath example

Linux

To get multipath information on Linux it is necessary to run the agent either under root or use sudo for "multipath -ll" command if it runs under ordinary user.
Sudo way is supported since the OS agent v7.20
Usage:
  • Put this into sudo, it supposes the OS agent running under lpar2rrd user:
    lpar2rrd  ALL = (root) NOPASSWD: /sbin/multipath -ll
    
  • Place "-m" parameter to OS agent start up script like this
    * * * * * /usr/bin/perl /opt/lpar2rrd-agent/lpar2rrd-agent.pl -m <lpar2rrd server hostname/IP>    > /var/tmp/lpar2rrd-agent.out 2>&1
