There are certain questions they need to answer to get maximum value for their team such as:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Will an observability tool support all kinds of workloads and heterogeneous systems?<\/li>\n\n\n\n<li>Will the tool support all kinds of data aggregation such as logs, metrics, traces, topology etc..?<\/li>\n\n\n\n<li>Will the investment in the (on-going or new) observability tool justified?<\/li>\n<\/ol>\n\n\n\n<p>In this article, we will provide the best way to get started with unified observability of your entire infrastructure using open source Skywalking and Istio service mesh.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Istio Service mesh of multicloud application&nbsp;<\/h2>\n\n\n\n<p>Let us take an example of a multicloud example where there are multiple services hosted on on-prem or managed Kubernetes clusters. The first step for unified observability will be to form a service mesh using Istio service mesh. The idea is that all the services or workloads in Kubernetes clusters (or VMs) should be accompanied with an Envoy proxy to abstract the security and networking out of business logic. As you can see in the below image a service mesh is formed and the network communication between edge to workloads, among workloads, and between clusters are controlled by the Istio control plane.&nbsp;<\/p>\n\n\n\n<p>In this case Istio service mesh emits a logs, metrics, traces for each Envoy proxies which will help to get unified observability. We need a visualization tool like Skywalking to collect the data and populate for granular observability.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"426\" src=\"https:\/\/imesh.ai\/blog\/wp-content\/uploads\/2023\/09\/Multicloud-Application-and-Istio.png\" alt=\"Multicloud Application and Istio\" class=\"wp-image-1554\" srcset=\"https:\/\/imesh.ai\/blog\/wp-content\/uploads\/2023\/09\/Multicloud-Application-and-Istio.png 1024w, https:\/\/imesh.ai\/blog\/wp-content\/uploads\/2023\/09\/Multicloud-Application-and-Istio-300x125.png 300w, https:\/\/imesh.ai\/blog\/wp-content\/uploads\/2023\/09\/Multicloud-Application-and-Istio-768x320.png 768w, https:\/\/imesh.ai\/blog\/wp-content\/uploads\/2023\/09\/Multicloud-Application-and-Istio-400x166.png 400w, https:\/\/imesh.ai\/blog\/wp-content\/uploads\/2023\/09\/Multicloud-Application-and-Istio-800x333.png 800w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\">Why Skywalking for Observability&nbsp;<\/h2>\n\n\n\n<p>SREs from large companies such as Alibaba, Lenovo, ABInBev, Baidu use Apache Skywalking and the common reasons are:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Skywalking aggregates logs, metrics, traces and topology.&nbsp;<\/li>\n\n\n\n<li>It natively supports popular service mesh software like Istio.

So we have enabled the appropriate rules:\n<ol class=\"wp-block-list\">\n<li>SW_OTEL_RECEIVER: default<\/li>\n\n\n\n<li>SW_OTEL_RECEIVER_ENABLED_HANDLERS: &#8220;otlp&#8221;<\/li>\n\n\n\n<li>SW_OTEL_RECEIVER_ENABLED_OTEL_RULES: &#8220;istio-controlplane,k8s-cluster,k8s-node,k8s-service,oap&#8221;<\/li>\n\n\n\n<li>SW_TELEMETRY: prometheus<\/li>\n\n\n\n<li>SW_TELEMETRY_PROMETHEUS_HOST: 0.0.0.0<\/li>\n\n\n\n<li>SW_TELEMETRY_PROMETHEUS_PORT: 1234<\/li>\n\n\n\n<li>SW_TELEMETRY_PROMETHEUS_SSL_ENABLED: false<\/li>\n\n\n\n<li>SW_TELEMETRY_PROMETHEUS_SSL_KEY_PATH: &#8220;&#8221;<\/li>\n\n\n\n<li>SW_TELEMETRY_PROMETHEUS_SSL_CERT_CHAIN_PATH: &#8220;&#8221;<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n\n\n\n<p>We have instructed Skywalking to collect data from Istio control plance, Kubernetes cluster, node, services and also <strong>oap <\/strong>(Observability Analytics Platform by Skywalking).<br><br>(The configurations from \u2018d\u2019 to \u2018i\u2019 enable Skywalking OAP&#8217;s self-observability, meaning it will expose Prometheus-compatible metrics at port 1234 with SSL disabled. Again in Step 3, we will configure the OTel collector to scrape this endpoint.)<\/p>\n\n\n\n<p>In the helm chart, we have also enabled the creation of a service account for Skywalking OAP.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step:3- Setting up Istio + Skywalking Configuration<\/h3>\n\n\n\n<p>After that we can install Istio using this <a href=\"https:\/\/github.com\/imesh-ai\/webinar\/blob\/main\/Unified%20Observability%20with%20Istio%20and%20Skywalking\/operator.yaml\">IstioOperator<\/a> configuration. In the IstioOperator configuration, we have set up the meshConfig so that every Sidecar will have enabled the envoy access logs service, and set the address for access logs service and metrics service to skywalking. Additionally with the proxyStatsMatcher, we are configuring all metrics to be sent via the metrics service<\/p>\n\n\n\n<pre class=\"wp-block-code has-white-color has-black-background-color has-text-color has-background\"><code>meshConfig:\r\n  defaultConfig:\r\n    envoyAccessLogService:\r\n      address: \"skywalking-skywalking-helm-oap.skywalking.svc:11800\"\r\n    envoyMetricsService:\r\n    \taddress: \"skywalking-skywalking-helm-oap.skywalking.svc:11800\"\r\n    proxyStatsMatcher:\r\n    \tinclusionRegexps:\r\n        - .*\r\n  enableEnvoyAccessLogService: true<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Step:4- OpenTelemetry Collector<\/h3>\n\n\n\n<p>Once the Istio and Skywalking configuration is done, we need to feed metrics from applications, gateways, nodes, etc to Skywalking.
