Set several hostnames for cluster checks (like check_icmp can)

[MarcusCaepio]

Hi Claudio,
using this awesome plugin to check several elastic clusters in icinga2. I have both local and "cluster" services, where the local checks are configured in the host objects themself and for the cluster checks, I define a "cluster" Host object. As check_icmp can check several Hosts and alert when hosts_alive < x, this fits nice for a general host check_command. But it would be nice, if I could also set several hostnames in es_system to get the cluster state from any of my configured nodes, without the need of using an HAproxy etc. What do you think about this?

Have a nice weekend.
Cheers,
Marcus

hi, I just ran into this, I had blindly used multiple instances of -e assuming this would extend the list.
do you think a regex for the valid mawsters would be a nice solution?

if so I can send a PR, I don't really like the idea of passing something like -e es-master,es-secondary,es-tertiary since the parsing would make the check a bit fugly.
