Exploring vuSiteManager

Overall Health

Here, the overall health of the vuSmartMaps cluster is displayed for the selected time range, indicating the availability of all VM hosts and K8s cluster components. If any VM host or K8s component is down, it will be shown under active alerts currently in vuSmartMaps, as well as all alerts that have ended (inactive alerts).

The first panel at the top represents the total number of alerts, indicating the quantification and severity of alerts in critical and warning states.

The overall health panel displays a bar graph representing the status of the vuSmartMaps cluster. Each bar represents the cluster’s status for an hour within the selected time range of the past 24 hours. If the health status is above 80%, the bar is shown in green, indicating good health. If the health status is below 80%, the bar is displayed in red, indicating critical health status for the vuSmartMaps cluster.

The Active Alerts panel showcases a table representing information related to the active alerts.

The following fields will be displayed as follows

  • Alert Name: The name or description of the active alert
  • Alert Type: The category or classification of the alert
  • Severity: The level of severity associated with the alert
  • Start Time: The timestamp indicating when the alert was triggered
  • End Time: The timestamp indicating when the alert was resolved (This field is empty, as the alerts remain unresolved)
  • Alert ID: A unique ID assigned to the alert for tracking and reference purposes.

Inactive alerts showcase a table representing information related to alerts that have been resolved. These alerts typically indicate the issues that were previously active but have since been resolved.

Availability

Availability provides a graphical depiction of the vuSmartMaps URL availability in the selected time range. It ensures accessibility by performing an HTTP request to the vuSmartMaps URL every minute.



The first panel at the top represents the total number of alerts, indicating how many are in the critical state and how many are in the warning state.



The availability panel displays a bar graph representing the availability of the vuSmartMaps cluster’s URL. For example, each bar represents the availability for an hour within the selected time range of the past 24 hours. If the availability is above 80%, the bar is shown in blue, indicating that the vuSmartMaps cluster has been available. If it is below 80%, the bar is displayed in red, indicating a reduction in the availability of the vuSmartMaps cluster URL.

VM Hosts

VM Hosts provide the user’s VM data in a tabular format. The following are the details displayed in this section:

  1. System: This displays the status of all the hosts
  2. CPU: This shows the CPU percentage usage and CPU load average (for 1 min and 5 min) for all hosts.
  3. Memory: Details of memory usage and availability for all hosts.
  4. Network IO: This tab presents network details such as data packets transferred and received by the hosts, along with the type of interface used.
  5. Disk IO: This section details disk read and write operations.
  6. Disk: This displays disk path and usage for respective hosts

Clicking on each of these tabs will take you to the corresponding table, where you can find detailed information.

Above the table, you’ll find a search box and an ‘Add Filter’ option, designed to streamline your search process.

In the search box, simply input the hostname or IP address of the system to initiate your search. Additionally, you have the option to add filters, such as Hostname and status, to further refine your search

💡Note: You can add more than one filter at a time. Filter options vary by VM Host type.

Alerts

The Status Alerts are triggered by vuSiteManager and created when any host or other Kubernetes resources go down. The severity of these alerts will be critical. The alerts section lists the details of these alerts in a tabular format.

VM Host Alert

The VM Host Alert section outlines the details of the alert triggered when the VM Host goes down.

The following are the fields displayed in the table:

  • Alert Name: Name or description of the alert
  • Alert Type: Category or classification of the alert
  • Severity: Level of severity associated with the alert
  • Start Time: Timestamp indicating when the alert was triggered.
  • End Time: Timestamp indicating when the alert was resolved
  • Alert ID: A unique ID assigned to the alert for tracking and reference purposes.

K8s Metrics

K8s (Kubernetes) Metrics outline the details of the alert triggered when any K8s metric goes down. It has individual tables for the following:

  • K8s Pods
  • K8s Deployment
  • K8s DaemonSet
  • K8s StatefulSet

Services

This section offers a comprehensive view of the status of all vuSmartMaps services operational within the user’s environment in the tabular format.

The following are the fields displayed in the table:

  • Timestamp: The date and time when the status information was recorded.
  • Name: The name of the vuSmartMaps service
  • Type: The type or category of the service (e.g., application, deployment).
  • Namespace: The namespace or logical grouping within which the service operates
  • Created time: The timestamp indicates when the service was created.
  • Pods: The number of pods associated with the service.
  • Status: The current operational status of the service.
  • Logs: A button that allows users to access the logs associated with the service

Users can access service logs directly by clicking the Logs button.

On clicking, it will showcase the log associated with a particular service

You can download this log by clicking the Download button located at the top left. Once clicked, the log file will be downloaded to your local system.

The refresh button enables you to update the status information, ensuring that you have the most recent and accurate data regarding the operational status of vuSmartMaps services within your environment.

K8s Metrics

Under the K8s (Kubernetes) Metrics section, you’ll find detailed information about the various health and performance metrics of your Kubernetes cluster.

K8s Pods

In Kubernetes, a pod is the smallest deployable unit. Think of it as a wrapper that encapsulates one or more containers, storage resources, a unique network IP, and configuration options. Pods are ephemeral by nature, meaning they can be easily created, destroyed, or replicated.

This section provides insights into the status and performance of the Kubernetes pods within your Kubernetes cluster, offering details such as their operational status and other relevant information.

K8s Pods have two tabs

    • Pods Status
    • Pods Performance

Pods Status

Under Pod status, the following are the fields displayed in the table:

  • TimestampIndicates the time at which the status information was last updated.
  • Pod NameSpecifies the name of the pod.
  • NamespaceIdentifies the namespace in which the pod is deployed.
  • HostnameSpecifies the hostname of the node where the pod is running
  • StatusDescribes the current operational status of the pod, such as “Running,” or “Not Running.”

Pod Performance

Under Pod Performance, the following are the fields displayed in the table:

  • TimestampIndicates the time at which the status information was last updated.
  • Pod Name: Specifies the name of the pod.
  • NamespaceIdentifies the namespace in which the pod is deployed.
  • HostnameSpecifies the hostname of the node where the pod is running
  • CPU UsageProvides information about the CPU usage of the pod, indicating the amount of CPU resources consumed
  • Memory UsageIndicates the memory usage of the pod, specifying the amount of memory resources utilized.
  • Disk IO (MB)This shows the amount of disk input/output (I/O) operations in megabytes (MB) performed by the pod, indicating disk usage and data read/write volume.

K8S DaemonSet

DaemonSets in Kubernetes ensures that a specific pod runs on every node within the cluster. They’re like background processes that run on each machine, providing services such as logging, monitoring, or networking. 

Here, you can view the status of the DaemonSets running across all nodes in your cluster. DaemonSets ensure that specific pods (or daemons) are running on all or a subset of nodes in the cluster.

The following are the fields displayed in the table:

  • TimestampIndicates the time at which the status information was last updated.
  • NameRepresents the name of the DaemonSet.
  • NamespaceSpecifies the namespace in which the DaemonSet is deployed.
  • HostIdentifies the node (host) within the cluster where the DaemonSet is running.
  • Created atDenotes the time when the DaemonSet was initially created.
  • ReplicasIndicates the desired number of replicas (instances) of the DaemonSet pods.
  • StatusDescribes the current status of the DaemonSet, such as whether it is running as expected or encountering any issues (Not Running).

K8s Deployment

Deployments in Kubernetes are used to manage sets of identical pods, typically for stateless applications. They ensure a specified number of pod replicas are running at any given time, and handle scaling, updates, and rollbacks automatically.

This section offers a status overview of Kubernetes Deployments, which manage the rollout and scaling of applications across the vuSmartMaps cluster.

The following are the fields displayed in the table:

  • TimestampIndicates the time at which the status information was last updated
  • NameSpecifies the name of the deployment.
  • NamespaceIdentifies the namespace in which the deployment is deployed.
  • HostSpecifies the host or node where the deployment is running.
  • Created TimeDenotes the time when the deployment was initially created.
  • ReplicasIndicates the desired number of replicas (instances) of the deployment.
  • StatusDescribes the current status of the deployment, such as whether it is successfully running, scaling, or encountering any issues.

K8S StatefulSet

StatefulSets are used for managing stateful applications, such as databases or key-value stores, in Kubernetes. Unlike stateless applications, stateful applications require unique identities and stable network addresses. StatefulSets ensure that each instance of a pod maintains its identity and can be managed effectively, making it suitable for databases or applications that require persistent storage.

In this segment, you’ll find information about StatefulSets, a controller used to manage stateful applications such as databases. Specifically, it outlines the status and management of stateful applications, ensuring stability and predictability.

The following are the fields displayed in the table:

  • TimestampIndicates the time at which the status information was last updated.
  • NameSpecifies the name of the StatefulSet.
  • NamespaceIdentifies the namespace in which the StatefulSet is deployed.
  • HostSpecifies the host or node where the StatefulSet is running.
  • Created TimeDenotes the time when the StatefulSet was initially created.
  • ReplicasIndicates the desired number of replicas (instances) of the StatefulSet.
  • StatusDescribes the current status of the StatefulSet, such as whether it is “Running” or “Not Running”.
