metrics

1. 创建一个namespace[kube-ops.yaml] 1 apiVersion: v1 2 kind: Namespace 3 metadata: 4 name: kube-ops 2. 设置配置文件[kube-config.yaml] 1 apiVersion: v1 2 kind: ConfigMap 3 metadata: 4 name: prometheus-config 5 namespace: kube-ops 6 data: 7 prometheus.yml: | 8 global: 9 scrape_interval: 15s 10 evaluation_interval: 15s 11 scrape_configs: 12 13 - job_name: 'kubernetes-apiservers' 14 kubernetes_sd_configs: 15 - role: endpoints 16 scheme: https 17 tls_config: 18 ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt 19 bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token 20 relabel

PerfMon Metrics Collector：服务器性能监控数据采集器。在性能测试过程中，还需要监控服务器的资源使用情况，如CPU、memory、I/O等。该插件可以在性能测试中实时监控服务器的各项资源使用。 JMeter 无法提取除 Tomcat 之外的其他服务器的默认指标，为了克服这一状况，研发了PerfMon Metrics Collector服务器代理，JMeter 通过这个代理来获取性能数据。PerfMon Metrics Collector使用的是SIGAR开源库，它是由一个 Java 通用部分和一个每个 OS 的本地库组合而成。 环境搭建 1、在服务器上搭建java环境 2、下载 ServerAgent-2.2.3.zip 3、用 Xftp 或 WinSCP 工具将 ServerAgent-2.2.3.zip上传到服务器 4、解压并启动服务器代理 $unzip ServerAgent-2.2.3.zip #解压 $rm -rf ServerAgent-2.2.3.zip #删除原压缩文件 $cd ServerAgent-2.2.3 $ll $sudo chmod 777 startAgent.sh #更改startAgent.sh文件的权限 $nohup ./startAgent.sh & #把代理服务放到后台并且不挂起 备注： 1）可以在运行脚本时添加-

I try to get "workingSet" metrics with pymongo. In MongoDB is just db.runCommand( { serverStatus: 1, workingSet: 1 } ) . I've tried in python from pymongo.mongo_client import MongoClient connection = MongoClient('localhost', 27017) db = connection['admin'] workingSetMetrics = db.command("serverStatus", "workingSet") print 'workingSetMetrics: ', workingSetMetrics My approach doesn't work. It the output isn't any "workingSet" metrics. Any idea how i can get those metrics programmatically in python? >>> import pymongo >>> c = pymongo.MongoClient() >>> c['admin'].command('serverStatus', workingSet

I want to know how many methods an interface declares or a class/enum implements. How to get that in Eclipse? A plugin like metrics could give you that: The eclipse-metrics plugin (another one) provided also a similar metric (Weighted Methods per Class) 来源： https://stackoverflow.com/questions/1831570/how-to-get-method-count-in-a-type-interface-class-enum-in-eclipse

I am trying to create some buttons with text in javascript using the Rahpael library. I would like to know the size of the styled text, before drawing to avoid that so I can create proper background (the button). Also I would like to avoid drawing the text outside of the canvas/paper (the position of the text is the position of its center). I can use Raphaels getBBox() method, but I have to create (draw) the text in first place to do this. So I draw text to get the size to be able to draw it on the right position. This is ugly. So I am searching for some general method to estimate the metrics

I've dockerized graphite and am working with this library to get metrics from an Apache Storm topology. I'm getting metrics data, but no matter what I do I can only get data per minute where I really need the points to be per second. As per this SO post I've set the retention policy to grab data every second. I've also set conf.put("topology.builtin.metrics.bucket.size.secs", 1); and void initMetrics(TopologyContext context) { messageCountMetric = new CountMetric(); context.registerMetric("digest_count", messageCountMetric, 1); } in the class that's setting up the topology and the bolt itself,

kubernetes1.16 版本对应最新的metrics-server为v0.3.5。 下载metrics-server配置文件 git clone https://github.com/kubernetes-incubator/metrics-server kubernetes1.16 对应的文件再目录 metrics-server/deploy/1.8+ 下。 下载后还要修改配置文件 metrics-server/deploy/1.8+/resource-reader.yaml 。 --- apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRole metadata: name: system:metrics-server rules: - apiGroups: - "" resources: - pods - nodes - nodes/stats - namespaces ## 如果这行没有请添加 verbs: - get - list - watch --- apiVersion: rbac.authorization.k8s.io/v1 kind: ClusterRoleBinding metadata: name: system:metrics-server roleRef: apiGroup: rbac
