Istio Monitoring (Kubernetes)

Introduction to Istio Monitoring for Kubernetes

​Istio is a service mesh that provides traffic management, policy enforcement, and telemetry collection for microservices. Using LogicMonitor's Istio package for Kubernetes, you can gather metrics from the backing Prometheus time-series database (TSDB) that comes bundled with Istio. LogicMonitor's Istio Kubernetes package supports Kubernetes only. ​

The LogicModules in the Istio Kubernetes package utilize the "/metrics" endpoint from the Prometheus pod on port 9090. By default, these LogicModules apply to the pod in the "istio-system" namespace labeled with "app=prometheus".

Compatibility

LogicMonitor's Istio Kubernetes package supports Kubernetes only. As Istio releases support for other platforms, LogicMonitor will test and extend coverage as necessary. ​

Setup Requirements

Import LogicModules

From the LogicMonitor Repository, import all Istio Kubernetes LogicModules, which are listed in the LogicModules in Package section of this support article.

Add Devices Into Monitoring

It is recommended that your Kubernetes cluster already be added into LogicMonitor for monitoring, as many of the AppliesTo properties set by Argus, LogicMonitor's open-source Kubernetes monitoring solution, are necessary for seamless operation. For instructions on adding your Kubernetes cluster into monitoring, see Adding your Kubernetes Cluster into Monitoring.

Port Access

The Istio Kubernetes package gathers metrics from the backing Prometheus TSDB that comes bundled with Istio. Istio must be installed on the Kubernetes cluster and port 9090, which is used to access the Prometheus "/metrics" endpoint, must be open to the Collector. ​

LogicModules in Package

​ LogicMonitor's Istio Kubernetes package consists of the following LogicModules. For full coverage, please ensure that all of these LogicModules are imported into your LogicMonitor platform.

When setting static datapoint thresholds on the various metrics tracked by this integration package, LogicMonitor follows the technology owner's best practice KPI recommendations. If necessary, we encourage you to adjust these predefined thresholds to meet the unique needs of your environment. For more information on tuning datapoint thresholds, see Tuning Static Thresholds for Datapoints.
