Hi Janaka,
Yes seems like thrift-client-config.xml file in haproxy extension has not
been updated. If you prefer you can send a pull request to fix it. Will
include the fix in the next release.
Regarding the second issue:
// echo "get weight <backend>/<server>" | socat stdio <stats-socket>
command = String.format("%s/get-weight.sh %s %s %s", scriptsPath,
backendId, member.getMemberId(), statsSocketFilePath);
try {
output = CommandUtils.executeCommand(command);
if ((output != null) && (output.length() > 0)) {
array = output.split(" ");
if ((array != null) && (array.length > 0)) {
weight = Integer.parseInt(array[0]);
if (log.isDebugEnabled()) {
log.debug(String.format("Member weight found:
[cluster] %s [member] %s [weight] %d", member.getClusterId(),
member.getMemberId(), weight));
}
totalWeight += weight;
}
}
}
We expect the first item of the array to be an integer. Will you be able to
execute socat stdio <stats-socket> and share the result?
Thanks
