Elasticsearch sum total values for specific hours within a month -


I have an elastic search server with fields: timestamp , user and bytes_down (among others)

I would like to complete a byte_down value for a user for one month but only where the hours from 8 am to 8 pm Yes,

I am able to get a daily sum with the date histogram along with the following query (I used the Perl API here I do not know one way to reduce it to the hour limit for every day. 

  my $ query = {index = & gt; 'Cm', body = & gt; {Query = & gt; {Filtered = & gt; {Query = & gt; {Word = & gt; {User = & gt; $ User}}, filter = & gt; {And = & gt; [{Border = & gt; {Timestamp = & gt; {Gte = & gt; '2014-01-01', lte = & gt; '2014-01-31'}}}, {bool = & gt; {Should> & gt; {Word = & gt; {Zone = & gt; $ Zone}}}}}}}}, aspect => {Bytes_down = & gt; {Date_histogram = & gt; {Field = & gt; 'Timestamp', interval = & gt; 'Day', value_field = & gt; 'Downstream'}}}, size = & gt; 0}};   
 Thanks Dell   
 
 
 I think you should filter instead You need to use  category  filter and then you have to enter the  facet_filter  section of your aspect:  
  "Facet_filter" = & gt; {"Script" = & gt; {"Script" = & gt; "Doctor ['timestamp]] date.getHourOfDay ()> gt; = 8 & amp; amp; amp; document [' timestamp ']. Date.getHourOfDay () <20"}}

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
