kill operation in monitoring not allowed...

It is possible that it is not displayed just because there is not enough space. Try maximizing the window.

Can you check that all the data returned has the following fields ['host', 'desc','active','opid']？ If any field is missing, the button will be invisible. It could be a flaw, and we'll fix it in the next version.

I don't see " host " what can i do ? . It's for this functionality I bought your software.

I don't know why there's no ”host" field. Any special settings for your MongoDB server? What version?

Here is a work-around solution to add host field if it does not exists. Please paste the following code.

var ops = db.currentOp({
active: true,
//waitingForLock : true,
//secs_running : { $gt : 3 }, //longer than 3 seconds
//$ownOps:true //returns information on the current user’s operations only.
//$all:true, //including operations on idle connections and system operations
//ns : /^db\.collection/
});

(ops.inprog || ops).map(it=>{return {host:"none", ...it}}) 

Thanks it work!!
