mongodb logfile entries 'end connection' -


i have mongodb 2.6.0 running on ubuntu 12.04 64-bit. database in replication set 1 node far. after running 3 weeks application uses mongodb hanged. @ excat time found following log entries in mongodb.log:

2014-08-17t06:41:27.408+0200 [clientcursormon]  connections:8 2014-08-17t06:41:27.408+0200 [clientcursormon]  replication threads:32 2014-08-17t06:45:20.863+0200 [conn2] end connection 127.0.0.1:40189 (7 connections open) 2014-08-17t06:45:20.863+0200 [conn1] end connection 127.0.0.1:40188 (7 connections open) 2014-08-17t06:45:20.866+0200 [conn3] end connection 127.0.0.1:40339 (5 connections open) 2014-08-17t06:45:20.866+0200 [conn7] end connection 127.0.0.1:60176 (4 connections open) 2014-08-17t06:45:20.866+0200 [conn8] end connection 127.0.0.1:60178 (3 connections open) 2014-08-17t06:45:20.867+0200 [conn6] end connection 127.0.0.1:51651 (2 connections open) 2014-08-17t06:46:27.451+0200 [clientcursormon] mem (mb) res:745 virt:51196 2014-08-17t06:46:27.451+0200 [clientcursormon]  mapped (incl journal view):50664 2014-08-17t06:46:27.451+0200 [clientcursormon]  connections:2 2014-08-17t06:46:27.451+0200 [clientcursormon]  replication threads:32

my question is: 'end connection' initiated client or server here? after these lines, mongodb server restarted. next lines on new logfile:

2014-08-17t06:47:02.674+0200 [signalprocessingthread] pid=1090 port=27017 64-bit host=efr02 2014-08-17t06:47:02.674+0200 [signalprocessingthread] db version v2.6.0 2014-08-17t06:47:02.674+0200 [signalprocessingthread] git version: 1c1c76aeca21c5983dc178920f5052c298db616c 2014-08-17t06:47:02.674+0200 [signalprocessingthread] build info: linux build14.nj1.10gen.cc 2.6.32-431.3.1.el6.x86_64 #1 smp fri jan 3 21:39:27 utc 2014 x86_64 boost_lib_version=1_49 2014-08-17t06:47:02.674+0200 [signalprocessingthread] allocator: tcmalloc 2014-08-17t06:47:02.674+0200 [signalprocessingthread] options: { config: "/etc/mongod.conf", processmanagement: { pidfilepath: "/var/lib/mongodb/mongod.pid" }, replication: { replset: "rs_ipzr_db" }, storage: { dbpath: "/mongodata" }, systemlog: { destination: "file", logappend: true, path: "/var/log/mongodb/mongod.log" } } 2014-08-17t06:51:27.488+0200 [clientcursormon] mem (mb) res:745 virt:51196

that looks restart or wrong? don't know, initiated restart nor find entry in local.db/startup_log. there last entry july 23.

could please point me right direction, find relevant information behaviour?

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
