Search query on page load and after selecting particular host?

[geetanjali]

Hello,

I have following query. $HostSelectBoxValue$ is drop down field name. I have to run this query on page load and also after selecting particular host. The default host is 'any' and value is '*'.

I want to show all hosts on page load and after selecting particular host, graph should show particular host's data graph.
Query is giving some problem.

index="power" sourcetype="power_usage" | eval host=if(HostSelectBoxValue=='$HostSelectBoxValue$','$HostSelectBoxValue$','*') | timechart max(Power_consumption) by host | sort 10 host

I think you can use search selector module in advanced view.

Also, you can define multiple host in static select.

I recommend App 'UI example" and ' 'side view'. These contains good example views. Please refer to them.
