Pacemaker / Cluster Web Interface

Hello all.



Has anyone written a web interface for any of Linux-HA? I'm thinking it
would be very useful for administration rather than initial set up. Also
I don't think it would be that hard as the web server would just have to
run certain commands and parse the output.



Features should include:

Realtime state of cluster - crm status / crm_mon -1

Resource scores - ptest -Ls

Resource migration graphs - ptest -Ls -save-dotfile

Cleaning up resources - crm resource cleanup $resource

Starting / Stopping resources - crm resource stop / start $resource

Migrating / Unmigrating resources - crm resource migrate $resource $node

Ldirectord (LVS) scores change - ipvsadm / edit ldirectord.cf

Log file search / displaying down to stack component e.g. lrmd ,
stonithd etc.



Is anyone working on anything like this? If there isn't anything out
there yet I'll certainly start writing something.



Cheers

Darren

Well, you could crm_mon -h <htmlfile> for this.

Basically no. There is some read-only stuff produced by crm_mon but
its not really extendable to be interactive in any way.
