Anaconda Enterprise provides detailed logs and monitoring information related to the Kubernetes services and containers it uses. You can use the Operations Center and Kubernetes CLI to access this information, to help diagnose and debug errors that you or other users may encounter while using the platform.
The Anaconda Enterprise cluster#
As an Operations Center Admin, you can use the Operations Center to configure and monitor the platform.
To access the Operations Center:
Click Manage Resources.
Login to the Operations Center using the Administrator credentials configured after installation.
To view resource utilization:
Select Servers in the menu on the left.
Click on the Private IP address of the Anaconda Enterprise master node, and select SSH login as root.
To display the current resource utilization of each node in the cluster, run this command:
kubectl top nodes --heapster-namespace=monitoring
This is actual resource utilization, not limits or requests.
To view utilization and requests for a particular node, run the
kubectl describe nodecommand against the IP address for the node (listed under
NAME). For example:
kubectl describe node 172.31.25.175
To view the resource utilization per pod, run this command:
kubectl top pods --heapster-namespace=monitoring
To view the current status of all pods in the cluster, run
kubectl get pods.
The following table summarizes common pod states:
The pod has been bound to a node, and at least one container is running.
The pod is waiting for one or more container images to be created.
The pod is in the process of being terminated.
An error has occurred with the pod.
The pod failed to start, and will make another attempt in a few minutes.
To view information for a particular pod, run the
kubectl describe podcommand against the pod (listed under
NAME). For example:
kubectl describe pod anaconda-session-89747d7fdb154b89b182d5eaa25b2e59-7f497db55wl9g
You can also use the Operations Center Logs to gain insights into pod behavior and troubleshoot issues. See logging for more information.
If a user experiences issues within a Notebook session, have them send you the name of the pod associated with their project session. They can obtain this information by running the
hostname command from within a Jupyter Notebook or terminal window.
You can then use the commands described above or the Operation Center’s Monitoring and Logs features to investigate the issue. See Monitoring sessions and deployments for more information.
As an Administrator, you can also use the Authentication Center to impersonate a user to try to reproduce the problem they are experiencing.
To access the Authentication Center:
Click Manage Users.
In the Manage menu on the left, click Users.
On the Lookup tab, click View all users to list every user in the system, or search the user database for all users that match the criteria you enter, based on their first name, last name, or email address.
Click Impersonate in the row of Actions for the user to display a table of all Applications this user has interacted with on the platform, including editor sessions and deployments.
Click the Anaconda Platform link to interact with Anaconda Enterprise as the user.
See Managing users for more information on managing users.
To help you troubleshoot issues with editor sessions, it might be helpful to understand what is happening “behind the scenes”.
When a user starts a session, Anaconda Enterprise launches the appropriate editor for them to work with their project files. In the background, the editor environment and other services are running in Docker containers.
To improve startup time for projects, the editor container includes conda environments for each of the project template environments provided by the platform. These environments are stored in
/opt/continuum/anaconda/envs, along with any custom environments created during the editor session.
The project repository is cloned into
/opt/continuum/project. (Only changes to files in this directory can be saved to the repository.)
anaconda-project preparecommand runs, scans the project’s
anaconda-project.ymlfile for new packages and environments, and installs them into the running session.
During this phase, you can monitor the progress by watching the output of
When this process completes, the
Any changes made to the container image will be lost when the session stops, so any packages installed from the command line are available during the current session only. To persist package installs across sessions, they must be added to the project’s
