question raised out of curiosity while working on sql query on vpn connection. vpn slow hence query performing slow. don't have direct access database server, test queries need run them through vpn :( is there way eliminate time taken network lag due vpn , know actual time taken query? without making copy of database , bringing local system/network. you network performance totally dependent on infrastructure. for identifying execution time can use time statistics. run below query set on set statistics time on; now run query. if switch "messages" table of results see below. execution time. sql server execution times: cpu time = 0 ms, elapsed time = 0 ms.

i have read files web address folder ...so have used below code ...i not getting list of files... string pathuser = "http:/mentpc.blob.core.windows.net/cents/201503"; string pathdownload = path.combine(pathuser, @"20150302110215315197/20150401100536436792"); webclient client = new webclient(); stream stream = client.openread(pathdownload); streamreader reader = new streamreader(stream); but getting exception saying ===>the remote server returned error: (404) not found. please me what error means, url not found. should pretty easy debug , check combined path in debugger. firstly don't think path.combine correct function use url's. path.combine used physical file paths. should using uri this. uri baseuri = new uri("http:/mentpc.blob.core.windows.net/cents/201503"); uri downloaduri = new uri(baseuri, "20150302110215315197/20150401100536436792"); also, looks trying access 2 files in same url. if case, need change ...

i'm trying deal following situation: class profile:mq { include rabbitmq } class rabbitmq ( $user, $pass, $host ) { ...logic... } i use hiera auto lookup fill in parameters in rabbitmq through profile::mq class (eg profile::mq:rabbitmq::user: "value", not rabbitmq::user: "value") guess encapsulate rabbitmq not sure how in puppet. automated data binding: plan. it doesn't work way propose, however. hiera keys given class looks parameter values depend on class , parameter names. independent of locus of , declarations of class. cannot otherwise, because multiple declarations of same class may evaluated same target node, , -- because classes singletons -- declare same class (instance). you may able achieve you're after putting rabbitmq parameter values in profile-specific level of hiera hierarchy. doesn't feel quite right me, may serve enough purposes.
