Monitoring Sisense on Linux

Previous Step

Sisense comes with several tools for monitoring the health of your Sisense deployment that allow you to troubleshoot any issues. These tools allow you to monitor the following areas:

  • Dashboard performance build times
  • Sisense cluster status
  • Sisense containers in your Kubernetes namespace

Sisense Monitor

Sisense Monitor provides information about dashboard performance and your ElastiCube builds. For example, you can identify if too many concurrent builds are affecting query performance and then take corrective action such as scheduling builds throughout the day.

For more information, see Sisense Monitor. To access Sisense Monitor, contact your CSM.

System Management

In the Admin page of Sisense, you can view the health of your nodes from the System Management tab.

Within the System Management tab, you can view which nodes are active, the status of your system, and a description of the system's hardware specifications.

Application Health Check

You can monitor the Sisense deployment using third-party tools to check its CPU and RAM usage, hard-disk health, and so on. However, what if the Sisense instance is functioning properly, but your dashboards don’t load? Third-party applications can’t monitor Sisense -specific services and aren't useful for tracking down the cause of these issues. To fill this gap, Sisense provides Application Health Check, an API to help you easily see if the Sisense queue is full, if your queries are processing properly, if your dashboards are loading, and so on.

There are several individual tests that you can perform with the Application Health Check API on your Sisense deployment. You can run all of the tests at once, or select the one(s) you want to run. The API performs tests that checks the health of the following in Sisense :

  • Dashboard loading and rendering services
  • ElastiCube building services
  • Reporting services
  • Infrastructure services
  • Logging services
  • Rate limiting services

To use this feature, you'll need to set up certain parameters for these tests. For example, for the test that evaluates the health of a specific ElastiCube , use the API to set the name(s) of the ElastiCubes to monitor.

You can also specify the inline test configurations instead of using the global preset tests. This enables you to configure health monitoring tests for ad-hoc use.

For technical API information about Application Health Check, see sisense.dev.

You can also run system monitoring tests via the REST API or a Command Line Interface (CLI). For more information, see Monitoring Sisense with APIs and CLI.

Grafana

Sisense provides a Grafana dashboard on Prometheus for monitoring your Sisense Linux cluster. This dashboard allows you to track performance and usage of different pods across different namespaces, investigate performance issues from a centralized location.

You can access your Grafana from the System Management tab:

OR

In your browser, type http://{IP}:(random _port*)/login

You can retrieve the port with the following command: kubectl get svc -n monitoring prom-operator-grafana

If you have set a base URL in a Linux environment that is accessed through SSH, you can't access Grafana through the Admin page until you update the URL of Grafana in your Linux CLI with the following command:

kubectl -n sisense set env deploy/grafana-sisense GF_SERVER_ROOT_URL=< Enter Your URL Here >/app/grafana

If you want to customize Grafna’s port, you can modify it in the default.yaml configuration file location in “sisense version number”/kubespray/default.yaml.

In this file, the value of grafana_port is 30300. You can modify this value to customize the port.

Kubernetes Dashboard

The Kubernetes Dashboard provides an interface for troubleshooting Sisense containers, and manage the cluster’s resources. You can use the dashboard to get an overview of how Sisense is running on your cluster as well as monitoring Sisense resources.

To access your Sisense Kubernetes dashboard, enter the following URLs into your browser:

Single Node Deployments
https://{IP}:6443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy

Multi-Node Deployments
https://{IP}:6443/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy

Note:

{IP} should be replaced with the IP address you defined in the config.yaml file when you provisioned Sisense.
