我正在尝试使用实时显示容器内存使用情况的Highchart。我希望Y轴上的内存使用量(30M,28M ......)和X轴上的内存使用时间。
因此,在我的收藏中,我'读'是什么时候我使用的是Unix时间,'memory_stats {usage}'是我要显示的用法。
然后我创建Highchart的代码是:
Template.chart.onRendered(function() {
data = [];
var cursor = Template.currentData(),
query = DockerStats.find(),
initializing = true,
liveChart;
data = [];
DockerStats.find().fetch().forEach(function(el) {
var date = new Date(el.read*1000);
// Hours part from the timestamp
var hours = date.getHours();
// Minutes part from the timestamp
var minutes = "0" + date.getMinutes();
// Seconds part from the timestamp
var seconds = "0" + date.getSeconds();
var time = hours + ":" + minutes + ":" + seconds;
data.push([time, el.memory_stats.usage]);
});
// Create basic line-chart:
liveChart = Highcharts.chart(cursor.chart_id, {
title: {
text: 'Memory usage of the controlcontainers_mongo_1'
},
xAxis: {
title: {
text: 'time reading'
}
},
yAxis: {
title: {
text: 'usage'
}
},
series: [{
type: 'line',
name: 'memory usage',
data: data
}]
});
// Add watchers:
query.observe({
added: function(addedThing) {
if (!initializing) {
var points = liveChart.series[0].points;
// console.log(points)
liveChart.series[0].addPoint([addedThing.memory_stats.usage]);
}
},
removed: function(removedThing) {
if (!initializing) {
var points = liveChart.series[0].points;
liveChart.series[0].addPoint([removedThing.memory_stats.usage]);
}
}
});
initializing = false;
});
有人可以帮我找到我在制作图表时遇到的错误吗?
