Cluster settings

Use the Cluster settings to create a clustered environment, to monitor the health of the cluster and its members, and to define managed networks for high availability and load distribution.

It is the responsibility of the Appliance Administrator or the Operations Administrator to create a cluster, monitor the status of the cluster, and define managed networks.

Before creating a Safeguard for Privileged Passwords cluster, become familiar with the Disaster recovery and clusters chapter to understand:

  • Go to Clusters:
    • web client: Navigate to Cluster.
    • desktop client: Navigate to Administrative Tools | Settings | Cluster.
    Table 157: Cluster settings
    Setting Description

    Cluster Management

    Where you create and manage a cluster and monitor the health of the cluster and its members.

    Managed Networks

    Where you define managed networks to distribute the task load for the clustered environment.

    Offline Workflow (automatic)

    Where you configure Offline Workflow Mode to automatically trigger if an appliance has lost consensus (quorum) and, optionally, automatically resume online workflow. You can also manually Enable Offline Workflow and Resume Online Operations from this dialog. For more information, see About Offline Workflow Mode.

    Session Appliances with SPS link

    Where you view, edit, and delete link connections when a Safeguard for Privileged Sessions (SPS) cluster is linked to a Safeguard for Privileged Password (SPP) for session recording and auditing. For more information, see SPP and SPS sessions appliance link guidance.

  • Cluster Management

    Cluster Management allows you to create and diagnosis clusters.

    The display of Cluster Management is different in the desktop client and the web client. Refer to the instructions for the client you are using.

    web client: Cluster Management

    When using Cluster Management from the web client, performing operations against other members of the cluster will incur a Cross-Origin Resource Sharing (CORS) HTTP request. This may require you to change the Trusted Servers, CORS, and Redirects setting to allow the specific host name being used in your web browser.

  • Navigate to Cluster | Cluster Management.

    Cluster Management grid

    • Health indicators: Health indicators display in the first column in the Cluster Management grid. Cluster members periodically query other appliances in the cluster to obtain their health information. Cluster member information and health information is cached in memory, with the most recent results displayed.

      The health indicators on the nodes indicate if cluster members are in any of these states:

      error: Indicates a definite problem impacting the functionality of the cluster

      warning: Indicates a potential issue with the cluster

      locked: Indicates the cluster is locked

      (green) healthy state.

      Expand the View More section to see more details.

    • Name: The name of the appliance.
    • Network Address: The IPv4 address (or IPv6 address) of the appliance configuration interface. You can modify the appliance IP address. For more information, see How do I modify the appliance configuration settings.
    • Primary: Displays Yes if the appliance is the primary.
    • Appliance State: Indicates the appliance state. For a list of available states, see Appliance states.

    When you select an appliance, the details for the appliance display on the right. The grid information displays: name, network address, primary, and state. This additional information is available:

    • Disk Space: The amount of used and free disk space.
    • Version: The appliance version number.
    • Last Health Check: Last date and time the selected appliance's information was obtained.
    • Uptime: The amount of time (days, hours, and minutes) the appliance has been running.
    • If the replica is selected, this additional information displays for the Primary:
      • Network Address: The network DNS name or the IP address of the primary appliance in the cluster
      • MAC Address: The media access control address (MAC address), a unique identifier assigned to the network interface for communications

      • Link Present: Displays either Yes or No to indicate if there is an open communication link

      • Link Latency: The amount of time (in milliseconds) it takes for the primary to communicate with the replica. Network latency is an expression of how much time it takes for a packet of data to get from one designated point to another. Ideally, latency is as close to zero as possible.

    • Errors and warnings are reported:
      • Errors: Errors are reported. For example, if an appliance is disconnected from the primary (no quorum), an error message may be: Request Workflow: Cluster configuration database health could not be determined.

  • Unlocking a locked cluster

    In order to maintain consistency and stability, only one cluster operation can run at a time. To ensure this, Safeguard for Privileged Passwords locks the cluster while a cluster operation is running, such as enroll, unjoin, failover, patch, reset, session module join, update IP, and audit log maintenance. While the cluster is locked, changes to the cluster configuration are not allowed until the operation completes.

    The lock notification displays as follows:

    • web client: The Appliance State will show a red lock icon ().
    • desktop client: In the Cluster view, the banner that appears at the top of the screen explains the operation in progress and a red lock icon () next to an appliance indicates that the appliance is locking the cluster.

    You should never cancel the cluster lock for an SPP unjoin, failover, cluster reset, restore, patch, or IP address update. Other considerations:

    • If a SPP join (enroll) is taking a long time, you may cancel it during the streaming audit data step.
    • If a patch distribution is taking a long time, you may cancel it and upload the patch to the replicas directly.
    • If an audit log synchronize operation is taking a long time, or you have reason to believe it will not complete due to a down appliance in the cluster, you may cancel it. Canceling this operation requires monitoring as detailed in Cancel Audit Log Maintenance from the Audit Log Maintenance page.
    • If an audit log archive or purge operation is taking a long time, or you have reason to believe it will not complete due to a down appliance in the cluster, you may cancel it. Canceling this operation requires monitoring as detailed in Cancel Audit Log Maintenance from the Audit Log Maintenance page.

    To unlock a locked cluster

    1. Go to Cluster Management:
      • web client: Navigate to Cluster | Cluster Management.
      • desktop client: Navigate to Administrative Tools | Settings | Cluster | Cluster Management.
    2. Click the lock icon in the upper right corner of the warning banner.
    3. In the Unlock Cluster confirmation dialog, enter Unlock Cluster and click OK.

      This will release the cluster lock that was placed on all of the appliances in the cluster and close the operation.

    IMPORTANT: Care should be taken when unlocking a locked cluster. It should only be used when you are sure that one or more appliances in the cluster are offline and will not finish the current operation. If you force the cluster unlock, you may cause instability on an appliance, requiring a factory reset and possibly the need to rebuild the cluster. If you are unsure about the operation in progress, do NOT unlock the cluster.

    Managed Networks

    Managed networks are named lists of network segments serviced by a specific Safeguard for Privileged Passwords (SPP) or Safeguard for Privileged Sessions (SPS) appliance in a clustered environment. Managed networks are used for scheduling tasks, such as password or SSH key change, account discovery, sessions recording, and asset discovery to distribute the task load. Using managed networks, you can:

    • Distribute the load so there is minimal cluster traffic.
    • Specify to use the appliances that are closest to the target asset to perform the actual task.

    An SPP cluster has a default managed network that consists of all cluster members. Other managed networks can be defined.

    CAUTION: If the role of a managed host that belongs to a linked SPS cluster is changed or if a managed host is added or removed from the cluster, SPP will detect the change by querying each Central Management node and attempt to stay in sync with the SPS cluster topology. If the Central Management node is down, SPP warns the administrator there may be invalid policies with a message like: The session connection policy was not found, in addition to flagging each broken Access Request Policy with an Invalid notation (Administrative Tools | Entitlements | Access Request Policies tab). Based on the size of your network and other factors, this will take one to 10 minutes and, during this time window, an unavailable managed host may continue to appear on the Managed Networks page. Any requests made will be invalid and will not be able to be launch sessions.

    Task delegation

    A Safeguard for Privileged Passwords' cluster delegates platform management tasks (such as password and SSH key check and password and SSH key change) to appliances based on platform task load. The primary appliance performs delegation and evaluates cluster member suitability using an internal fitness score that is calculated by dividing the number of in-use platform task threads by the maximum number of allowed platform task threads.

    The maximum number of allowed platform task threads can be adjusted using the Appliance/Settings API and adjusting the MaxPlatformTaskThreads value. By adjusting this number, you can tune task distribution.

    IMPORTANT: Adjusting the MaxPlatformTaskThreads will impact SPP's available resources for handling access requests and may impact user experience. Best practice is to engage Professional Services if the value may need to be changed.

    Increasing the maximum number of allowed platform task threads will decrease the fitness score thus increasing the number of tasks passed to that appliance.

    The fitness score is cached and is recalculated in 8-minute intervals when the scheduler is not busy. When the scheduler is running tasks, the fitness score is calculated more frequently so the scheduler can dynamically adjust.

    The selection of a Safeguard for Privileged Sessions (SPS) Appliance is primarily dependent on managed network rules. However, if there aren't any managed network rules or if the managed network rules result in more than one SPS appliances selected, a fitness score is used as the tie breaker. The fitness score is calculated based on the percentage of disk available minus the overall load average of the SPS appliance. (Load average is a Linux metric which provides a numerical indication of the overall resource capacity in use on the server.) The higher the fitness score, the more likely that the corresponding appliance will be selected.

    Precedence

    The selection made on the Entitlement | Access Request Policy tab takes precedence over the selections on Settings | Cluster | Managed Networks page. If a Managed Networks rule includes nodes from different SPS clusters, SPP will only select the nodes from the same cluster that was assigned on the Session Settings page of the Access Request Policy tab.

    IMPORTANT: Discovery, password and SSH key check and change will not work if a managed network has been configured with a subnet but is not assigned to an appliance (the appliance is blank). If the managed network does not have an assigned appliance, a message like the following displays: No appliances in network '<NameOfEmptyNetwork>' available to execute platform task request. To resolve the issue, assign at least one appliance to manage the passwords, SSH key, and/or sessions or delete the managed network entry.

    Go to Managed Networks:

    • web client: Navigate to Cluster | Managed Networks.
    • desktop client: Navigate to Administrative Tools | Settings | Cluster | Managed Networks.

    The Managed Networks page displays the following information about previously defined managed networks. Initially, this page contains the properties for the Default Managed Network, which implicitly includes all networks and is served by all appliances in the cluster.
