language agnostic - Does there exist an open-source distributed logging library? -

-

i'm talking library allow me log events different machines , align these events on "global" time axis sufficiently high precision.

actually, i'm asking because i've written such thing myself in course of cluster computing project, found terrifically useful, , surprised couldn't find analogues.

therefore, point whether exists (and better contribute it) or nothing exists (and better write open-source analogue of solution).

here features i'd expect such library:

  • independence on clock offset between different machines
  • timing precision on order of @ least milliseconds, preferably microseconds
  • scalability thousands of concurrent logging processes, @ least several megabytes of aggregated logs per second
  • soft real-time operation (t.i. don't want collect 200 big logs 200 machines , compute clock offsets , merge them - want see happens "live", perhaps small lag 10s)

facebook's contribution in matter called 'scribe'.

excerpt:

scribe server aggregating streaming log data. designed scale large number of nodes , robust network , node failures. there scribe server running on every node in system, configured aggregate messages , send them central scribe server (or servers) in larger groups.

...

scribe implemented thrift service using non-blocking c++ server. installation @ facebook runs on thousands of machines , reliably delivers tens of billions of messages day.

the api thrift-based, have platform coverage, in case you're looking simple integration java may want have @ digg's log4j appender scribe.

ho can set spacing beween stars? thats ratingbar: ratingbar = (ratingbar) inflater.inflate(r.layout.ratingbar, null); ratingbar.setlayoutparams(new layoutparams(layoutparams.wrap_content, layoutparams.wrap_content)); the layout: <?xml version="1.0" encoding="utf-8"?> <ratingbar xmlns:android="http://schemas.android.com/apk/res/android" style="@style/mystyle" android:layout_alignparentright="true" android:layout_height="19dp" android:layout_width="wrap_content" android:numstars="5"> </ratingbar> the style: <style name="mystyle" parent="@android:style/widget.ratingbar"> <item name="android:progressdrawable">@drawable/android_r2_ratingstar_yellow</item> <item name="android:indeterminatedrawable">@drawable/android_r2_ratingstar_grey</item> </style> thanks, cheers you have

i'm using devexpress grid , i'm trying 'country' column display header filter properly: <dx:gridviewdatacolumn caption="country" fieldname="countryname" showincustomizationform="true" visible="false"> <settings allowheaderfilter="true"/> </dx:gridviewdatacolumn> if 'country' column set visible='true', header filter displayed should(it shows value option list). however, want 'country' column hidden, available in customization window(like in code above). in case, when column dragged outside customization window , grid , header filter clicked, javascript error encountered: element null element.addeventlistener(eventname, func, true); is known bug? there workarounds? set aspxgridview.settings.showheaderfilterbutton property true resolve problem. the following markup works fine me (i using dxperience 10.1.7): <asp:accessdatasource id="accessda
