myq_gadgets's Issues

Use --login-path for 5.6 pxc

Hello

More a feature request than an issue :-)
Output gets very ugly on 5.6 Clusters:

./myq_status -u root -p ... wsrep

I altered MySQL_Script_Utils.pm quick and dirty:
from:

my @output = `echo "$sql" | mysql $user_str $pass_str $host_str $port_str`;

to:

my @output = `echo "$sql" | mysql --login-path=$user $host_str $port_str`;

Better:

./myq_status -u root  wsrep
c1 / node (idx: 2) / Galera 3.7(r7f44a18)
Wsrep    Cluster  Node Repl  Queue     Ops       Bytes     Conflct   Gcache    Window        Flow

Perhaps the easiest way would be a --login-path command line option.

Release Tag with version number

it would be awesome if you could create an GitHub release tag with the version number(s) from the change log. This would help me a lot to create a package from your fantastic scripts based on the version number.

Thanks a lot for your work.

The "commands" view is not readable

The output is similar to the following:

./myq_status commands

This is not as readable as the other views.

myq_status wsrep sets wsrep_cluster_size to 0

whenever i run myq_status wsrep somehow the cluster size becomes 0 and doesn't recover until i do a restart of the node.
The node still behaves as it is fully connected except for the cluster size.
