Pool Member status page iRule Version 11

looks like the scan is expecting the data string to be without the quotes:

% set x {"lp1/192.168.101.20:514",}
"lp1/192.168.101.20:514"
% scan $x {%[^/]/%[^:]:%s} poolname addr port
3
% puts $poolname
"lp1 **wrong!**
% puts $addr
192.168.101.20
% puts $port
514", **wrong!**

so you can either change the bash script to not echo the quotes (best) for each pool/ip/port, or string them off before passing to scan (see below), or update the scan command to account for them.

% set x {"lp1/192.168.101.20:514",}
"lp1/192.168.101.20:514",
% scan [string range $x 1 end-2] {%[^/]/%[^:]:%s} poolname addr port
3
% puts $poolname
lp1
% puts $addr
192.168.101.20
% puts $port
514
